The aim of operative treatment for ankle fractures is to allow early movement after internal fixation. The hypothesis of this study was that early mobilization would improve functional recovery in patients after surgery for ankle fractures.
                In a prospective randomized controlled study, 66 consecutive patients with ankle fractures that required open reduction and internal fixation (ORIF) were assigned to one of two postoperative regimens: immobilization in a nonweightbearing below-knee cast or early mobilization in a removable cast. Four patients were excluded from the study, leaving 62 for review.
                Patients who had early mobilization in a removable cast had higher functional scores (Olerud-Molander and AOFAS) at 9 and 12 weeks postoperatively. They also returned to work earlier (67 days) compared with those treated in nonweightbearing below-knee cast (95 days), p<0.05. There was no statistical difference in Quality of Life (SF-36 Questionnaire) at 6 months between the two groups. We had an approximately 10% postoperative infection trend (one superficial and two deep) in the early mobilization group.
                Despite the overall short-term benefit of early mobilization, we had three patients in the early mobilization group who had wound complications. Both the surgeon and patient should be aware of the higher risk of wound complications associated with this treatment, and thus the accelerated rehabilitation protocol should be individualized. Sixty-one active-duty military personnel with operatively treated ankle fractures were randomized into two postoperative immobilization regimens: Group I--six weeks short-leg cast, nonweight-bearing; Group II--six weeks removable orthosis, nonweightbearing. Group I began physical therapy at six weeks postoperatively, and Group II began physical therapy within the first postoperative week. Objective measurements of swelling, strength, range of motion, and functional tests were examined. Subjective scores of pain, function, cosmesis, and motion were recorded. Patients in Group II (early mobilization) had significantly better subjective scores at three and six months postoperatively; however, time to return to duty was not significantly different. Objective tests of swelling, strength, range of motion, and functional tests were not significantly different at three months postoperatively for either group. Early mobilization in a removable orthosis, while not objectively altering the postoperative course, provides a safe, preferable method of treatment in the reliable and cooperative patient. Adequate and intensive rehabilitation is an important requirement for successful total knee arthroplasty. Although research suggests that Continuous Passive Motion (CPM) should be implemented in the first rehabilitation phase after surgery, there is substantial debate about the duration of each session and the total period of CPM application. A Cochrane review on this topic concluded that short-term use of CPM leads to greater short-term range of motion. It also suggested, however, that future research should concentrate on the treatment period during which CPM should be administered.
                In a randomised controlled trial we investigated the effectiveness of prolonged CPM use in the home situation as an adjunct to standardised PT. Efficacy was assessed in terms of faster improvements in range of motion (RoM) and functional recovery, measured at the end of the active treatment period, 17 days after surgery. Sixty patients with knee osteoarthritis undergoing TKA and experiencing early postoperative flexion impairment were randomised over two treatment groups. The experimental group received CPM + PT for 17 consecutive days after surgery, whereas the usual care group received the same treatment during the in-hospital phase (i.e. about four days), followed by PT alone (usual care) in the first two weeks after hospital discharge. From 18 days to three months after surgery, both groups received standardised PT. The primary focus of rehabilitation was functional recovery (e.g. ambulation) and regaining RoM in the knee.
                Prolonged use of CPM slightly improved short-term RoM in patients with limited RoM at the time of discharge after total knee arthroplasty when added to a semi-standard PT programme. Assessment at 6 weeks and three months after surgery found no long-term effects of this intervention Neither did we detect functional benefits of the improved RoM at any of the outcome assessments.
                Although results indicate that prolonged CPM use might have a small short-term effect on RoM, routine use of prolonged CPM in patients with limited RoM at hospital discharge should be reconsidered, since neither long-term effects nor transfer to better functional performance was detected.
                ISRCTN85759656. There have been few randomized controlled trials evaluating nonoperative treatment of proximal humeral fractures. To investigate shortening the period of dependence, we assessed the feasibility and efficacy of early mobilization of the shoulder (within three days after the fracture) in comparison with those of conventional three-week immobilization followed by physiotherapy.
                We randomly assigned seventy-four patients with an impacted proximal humeral fracture to receive early passive mobilization or conventional treatment. The primary outcome was the overall shoulder functional status (as measured with the Constant score) at three months. The secondary outcomes were the Constant score at six weeks and at six months, the change in pain (on a visual analog scale), and the active and passive range of motion.
                At three months and at six weeks, the early mobilization group had a significantly better Constant score than did the conventional-treatment group (between-group difference, 9.9 [95% confidence interval, 1.9 to 17.8] [p = 0.02] and 10.1 [95% confidence interval, 2.0 to 18.1] [p = 0.02], respectively) and better active mobility in forward elevation (between-group difference, 12.0 [95% confidence interval, 1.7 to 22.4] [p = 0.02] and 28.1 [95% confidence interval, 7.1 to 49.1] [p = 0.01], respectively). At three months, the early mobilization group had significantly reduced pain compared with the conventional-treatment group (between-group difference, 15.7 [95% confidence interval, 0.52 to 30.8] [p = 0.04]). No complications in displacement or nonhealing were noted.
                Early mobilization for impacted nonoperatively treated proximal humeral fractures is safe and is more effective for quickly restoring the physical capability and performance of the injured arm than is conventional immobilization followed by physiotherapy. To investigate the short- and long-term effects of a multidisciplinary postoperative rehabilitation programme in patients with femoral neck fracture.
                A randomized controlled trial in patients (n = 199) with femoral neck fracture, aged >or= 70 years.
                The primary outcomes were: living conditions, walking ability and activities of daily living performance on discharge, 4 and 12 months postoperatively. The intervention consisted of staff education, individualized care planning and rehabilitation, active prevention, detection and treatment of postoperative complications. The staff worked in teams to apply comprehensive geriatric assessment, management and rehabilitation. A geriatric team assessed those in the intervention group 4 months postoperatively, in order to detect and treat any complications. The control group followed conventional postoperative routines.
                Despite shorter hospitalization, significantly more people from the intervention group had regained independence in personal activities of daily living performance at the 4- and 12-month follow-ups; odds ratios (95% confidence interval (CI) ) 2.51 (1.00-6.30) and 3.49 (1.31-9.23), respectively. More patients in the intervention group had also regained the ability to walk independently indoors without walking aids by the end of the study period, odds ratio (95% confidence interval) 3.01 (1.18-7.61).
                A multidisciplinary postoperative intervention programme enhances activities of daily living performance and mobility after hip fracture, from both a short-term and long-term perspective. There is an increasing drive to make nursing care evidence-based. High quality evidence from systematic reviews relevant to postoperative pain relief exists, yet pain after surgery remains poorly controlled for many patients. This study aimed to assess whether implementing evidence-based pain management improved postoperative pain outcomes. Pain on a 0-10 scale was the primary outcome and analgesic consumption a secondary outcome. A baseline audit was undertaken on four surgical wards to establish whether there was a need for the study. A randomized-controlled trial was then designed to assess the effects of implementing an evidence-based approach to postoperative pain management. The four wards were randomized to receive the intervention or act as a control. Outcomes were assessed 3 months after the intervention on both intervention and control wards. The intervention (implementation of an oral analgesic algorithm derived from systematic reviews) was then implemented on the control wards and outcomes reassessed after 3 months on the control wards. The intervention was designed using an evidence-based approach to effective implementation. Four interactive sessions covered: (1) detailed feedback of baseline data and discussion (utilizing audit and feedback), (2) why systematic reviews, analgesic league tables and choice of drugs to develop an analgesic algorithm (see Figure 1), (3) principles of evidence based health care (EBHC), including critical appraisal and (4) facilitation and change workshop. The findings revealed no significant differences in pain level or drug use between the intervention and control wards. However, the control wards also changed during the control period. Possible explanations for this are discussed. When looking at changes compared with baseline, both intervention and control wards increased their use of algorithm drugs and reduced use of non-algorithm drugs during the study. No effects were found on pain in the intervention wards. Pain ratings at rest since surgery, on movement since surgery and worst pain on movement were significantly reduced compared with baseline in the control wards. Although there are many pressures to utilize a randomized-controlled trial study design in the culture of evidence-based health care, there will be times, especially when implementing complex changes in practice that other types of design should be considered. A randomised, controlled study of the use of postoperative continuous passive motion (CPM) and immobilisation regimen after total condylar knee arthroplasty was performed. CPM resulted in a significant increase in both the early and late range of knee flexion. This increase occurred in both rheumatoid and osteoarthritic patients. The improvement of 10 degrees at 12 months allowed additional important function to be attained. CPM resulted in significantly earlier discharge from hospital. It did not increase the clinical incidence of wound healing problems, nor did it significantly increase the postoperative fixed flexion deformity or the extension lag. CPM can be recommended as a safe and effective modality to achieve more rapid and more successful postoperative rehabilitation after knee arthroplasty. Several studies have documented the clinical efficacy of guided tissue regeneration (GTR) with non-resorbable expanded polytetrafluoroethylene (ePTFE) membranes and enamel matrix proteins (EMP) in the treatment of infrabony defects. The objective of this controlled clinical study was to compare the clinical outcomes of 3 surgical modalities in the treatment of deep interproximal infrabony defects.
                Ninety (90) defects in 90 healthy subjects affected by chronic periodontitis were assigned to 1 of 3 treatment groups by blocking to prognostic variables. The test group was treated with the application of EMP and the simplified papilla preservation (SPP) technique; the second group was treated with titanium-reinforced ePFTE membranes and the SPP technique; and the third group was treated with the SPP technique used as access flap control procedure. No differences were observed in terms of baseline oral hygiene and defect characteristics among the 3 groups, indicating that the blocking approach was effective. A stringent infection control program was adopted for 1 year.
                The 1-year results indicated that: 1) all treatment modalities resulted in clinically significant improvements in clinical attachment levels (CAL) and reduction in probing depth (PD); 2) a statistically significant treatment effect was demonstrated comparing the EMP test, the membrane control, and the flap control groups in terms of CAL gains; 3) both the EMP test and the membrane control groups showed significant CAL gains compared to the flap control group; 4) a statistically significantly greater amount of CAL gain was demonstrated in GTR-treated compared to EMP-treated patients; 5) deeper residual probing depths but smaller increases in gingival recession were demonstrated following EMP therapy; and 6) smoking habits reduced the clinical outcomes of both regenerative procedures.
                The use of a regenerative procedure is indicated in the treatment of deep vertical bony defects since both the regenerative techniques (GTR and EMD) in the present study resulted in clinically and statistically significant improvements in clinical parameters compared to the access flap procedure. The use of EMP can be helpful in esthetically-sensitive sites and in reducing patient morbidity. To compare elastic stable intramedullary nailing (ESIN) with nonoperative treatment of fully displaced midshaft clavicular fractures in adults.
                The study was a randomized, controlled, clinical trial.
                Level 1 trauma center.
                Sixty patients between 18 and 65 years of age participated and completed the study. They were randomized to either operative or nonoperative treatment with a 2-year follow-up.
                Thirty patients were treated with a simple shoulder sling and 30 patients with ESIN within 3 days after trauma.
                Complications after operative and nonoperative treatments, Disabilities of the Arm, Shoulder and Hand (DASH) score and Constant Shoulder Score for outcome measurement, and clavicular shortening.
                Fracture union was achieved in all patients in the operative group, whereas nonunion was observed in 3 of 30 patients of the nonoperative group. Two symptomatic malunions required corrective osteotomy in the nonoperative group. Medial nail protrusion occurred in 7 cases in the operative group. Implant failure with revision surgery was necessary in 2 patients after an additional adequate trauma. DASH scores were lower in the operative group throughout the first 6 months and 2 years after trauma, with a significant difference during the first 18 weeks. Constant scores were significantly higher after 6 months and 2 years after intramedullary stabilization. Patients in the operative group showed a significant improvement of posttraumatic clavicular shortening; they were also more satisfied with cosmetic appearance and overall outcome.
                ESIN of displaced midshaft clavicular fractures resulted in a lower rate of nonunion and delayed union, a faster return to daily activities, and a better functional outcome. Clavicular shortening was significantly lower, and overall satisfaction was higher in the operative group. We compared the efficacy of the Medoff sliding plate (MSP) with 3 other screw-plate systems for fixation of unstable intertrochanteric fractures in a randomized multicenter trial of 569 elderly patients. The MSP has biaxial dynamic capacity along both the neck and the shaft of the femur unlike the other systems, which lack dynamic capacity along the shaft. 268 fractures were operated on with the MSP, and 301 with the dynamic hip screw (DHS), with or without a trochanteric stabilizing plate (DHS/TSP) or with the dynamic condylar screw (DCS). The MSP had recently been shown to the surgeons. The patients in the groups were similar as regards age, domestic situation, preinjury walking ability and type of fracture. We followed the patients clinically and radiographically for at least 1 year. There was no significant difference in walking ability at follow-up or rate of return to home. Fixation failure occurred in 18/268 fractures operated on with the MSP, in 8/238 with the DHS, in 3/49 with the DHS/TSP and in 1/14 with the DCS. The difference in the rate of fixation failure was not statistically significant when the MSP group was compared to the 3 other groups. In 14 of the 18 fixation failures in the MSP group, the biaxial dynamic capacity of the MSP had not been used due to technical errors by surgeons, unfamiliar with the new method. No selection bias was found regarding fracture types in the 2 subgroups of patients with correct or inadequate biaxial dynamization. Extramedullary fixation of unstable intertrochanteric fractures with these implants showed a low failure rate. When using the MSP, biaxial dynamization must be correctly performed. There is no consensus about the management of acute primary traumatic patellar dislocation in young physically active adults. The objective of this study was to compare the clinical outcomes after treatment with and without initial stabilizing surgery for primary traumatic patellar dislocation in young adults.
                Forty young adults, thirty-seven men and three women with a median age of twenty years (range, nineteen to twenty-two years), who had an acute primary traumatic patellar dislocation were randomly allocated to be treated with initial surgical stabilization (eighteen patients, with each receiving one of two types of initial stabilizing procedures) or to be managed with an orthosis (twenty-two patients, including four who had osteochondral fragments removed arthroscopically). After a median of seven years, thirty-eight patients returned for a follow-up examination. Redislocations, subjective symptoms, and functional limitations were evaluated. Radiographs and magnetic resonance images were obtained at the time of randomization, and twenty-nine (76%) patients underwent magnetic resonance imaging at the time of final follow-up.
                A hemarthrosis as well as injuries of the medial retinaculum and the medial patellofemoral ligament were found on magnetic resonance imaging in all patients at the time of randomization. During the follow-up period, six of the twenty-one nonoperatively treated patients and none of the seventeen patients treated with surgical stabilization had a redislocation (p = 0.02). Four nonoperatively treated patients and two patients treated with surgical stabilization reported painful patellar subluxation. The median Kujala scores were 91 points for the surgically treated patients and 90 points for the nonoperatively treated patients. Thirteen patients in the surgically treated group and fifteen in the nonoperatively treated group regained their former physical activity level. At the time of follow-up, a full-thickness patellofemoral articular cartilage lesion was detected on magnetic resonance imaging in eleven patients; the lesions were considered to be unrelated to the form of treatment.
                In a study of young, mostly male adults with primary traumatic patellar dislocation, the rate of redislocation for those treated with surgical stabilization was significantly lower than the rate for those treated without surgical stabilization. However, no clear subjective benefits of initial stabilizing surgery were seen at the time of long-term follow-up. We conducted a prospective, randomized study to determine if patients with midshaft clavicle fractures would benefit from immediate operative stabilization with a modified Hagie pin in comparison with a matched group treated with nonoperative therapy. At a level II trauma center, patients with closed midshaft clavicle fractures were prospectively randomized to receive either operative or nonoperative treatment. Fifty-seven (29 operative, 28 nonoperative) patients were enrolled in the study. Operative patients underwent open reduction and internal fixation of the clavicle using a modified Hagie pin; nonoperative patients were treated with a sling for comfort. All patients were followed at regular intervals for 1 year. They were evaluated for radiographic healing and complications and were scored with the Single Assessment Numeric Evaluation and L'Insalata instruments. Injury severities and radiographs were not statistically significantly different between the 2 groups. Functional scores in the operative group were slightly higher at 3 weeks, and the nonoperative group had slightly higher scores at 6 months and 1 year. The only statistically significant difference between the groups was at 3 weeks. Percentage follow-up at 1 year was 93% for the operative group and 82% for the nonoperative group. One patient in each group developed a nonunion, and 1 patient in each group had a refracture. Complications were higher in the operative group, and most were related to pin prominence at the posterior shoulder. Results of this study suggest that, though patients with midshaft clavicle fractures had higher functional scores at short-term follow-up after internal fixation, functional scores were similar at 6 months and 1 year. In addition, internal fixation with a modified Hagie pin was associated with a higher complication rate. We performed a prospective randomized study on 60 patients with dorsally displaced extra-articular or noncomminuted intraarticular fractures of the distal radius. All 60 fractures were treated by closed reduction and Kirchner wire trans-styloid fixation. 30 patients had 1 weeks' postoperative immobilization and 30 patients had 6 weeks' immobilization. All patients had a clinical and radiographic review at 6 weeks and at 1 year after the operation. Pain, range of movement and grip strength were tested clinically, and changes in dorsal tilt, frontal radial deviation, ulnar variance, and radial shortening were assessed radiographically. Rates of complications were the same in both groups. At follow-up, pain was similar in both groups and range of motion and grip strength were somewhat better after early mobilization--in comparison with the opposite wrist--but this was statistically significant only for ulnar deviation. The postoperative radiographic reductions were similar in both groups, with no differences in loss of reduction after bone healing. Therefore, in Colles' fractures, trans-styloid fixation with two K-wires seems to give a stable osteosynthesis, which does not need additional immobilization with a plaster cast. Numerous studies have been published regarding the comparison between intramedullary nail and the dynamic hip screw and plate for the fixation of intertrochanteric fractures in elderly patients. In this paper we present a comparative study of these two methods regarding their systemic effects on this group of patients.
                This is a randomized trial of 120 consecutive patients with an intertrochanteric fracture treated with either extramedullary fixation (dynamic hip screw and plate; DHS, Synthes-Stratec, Oberdorf, Switzerland) or intramedullary nail (Gamma nail, Stryker Howmedica, Freiburg, Germany and Endovis BA, Citieffe, Bologna, Italy). The parameters that we assessed pre-operatively, in addition to their demographics, included their mental state (MMSE), their nutritional and immune state and their pulmonary function. Intra-operatively we calculated the amount of radiation exposure, the amount of blood loss and the length of operative time for each procedure. Postoperatively we repeated the calculation of the mental and pulmonary state and the blood loss, during days 1, 3, and 10 and related them to the ease of the patient's mobilization.
                Decreased bleeding and post-operative pain, reduced post-operative morbidity and faster recovery of function were better but not significant in the group of intramedullary fixation (all p>0.05). However, in the same group there were slightly more patients in whom the MMSE was falling, together with their pulmonary function, suggesting that this method probably predisposes to higher chances of pulmonary dysfunction and the possibility of pulmonary embolism.
                We found no significant differences between the two methods of stabilization of these fractures regarding their systemic effects perioperatively. The classic dynamic hip screw can preserve its position as a safe and effective solution for these already vulnerable patients having sustained a trochanteric fracture against the novel intramedullary techniques.
                Copyright 2009. Published by Elsevier Ltd. To compare postoperative collaborative care between orthopaedic surgeons and physicians in geriatric medicine with routine orthopaedic care in elderly women with proximal femoral fracture.
                Exclusion of patients dying before fit enough to enter trial, those with pathological fractures, those likely to be discharged within seven days of entering the trial, and those remaining unfit for transfer to a peripheral hospital. Remainder allocated to two groups: treatment group and control group.
                District hospital acute admission ward and rehabilitation ward.
                144 sequentially admitted elderly women with proximal fracture of the femur; 36 excluded on above criteria and remainder entered into trial.
                Both treatment and control groups (n = 54 in each) received physiotherapy and other services. The treatment group also received thrice weekly supervision by a geriatrician.
                Physical independence, residence after discharge, and length of hospital stay.
                At discharge significantly more patients in treatment group were independent in terms of activities of daily living than controls (41 v 25) and their median stay was 24 days (range 8-197) compared with 41 (9-365) (95% confidence intervals for difference 2 to 25). Significantly fewer treatment patients were discharged to institutional care (10% v 32%; 95% confidence interval for difference 6% to 37%) and more to their own homes (63% v 38%; 95% confidence interval for difference 6% to 44%). These beneficial effects were consistent across a range of ages and mental state.
                Both hospital and patient benefited when postoperative rehabilitation was provided in a setting specialising in such care for elderly patients with trauma. In a prospective randomized trial the early functional results after immobilisation in a cast were compared to those after using a vacuum stabilizing system. The vacuum stabilizing system Vacoped offers equivalent stability compared to a plaster cast. In contrast to the cast the Vacoped can be removed for body care and physical therapy. Additionally the range of motion for dorsal flexion/extention in the upper ankle joint can be adjusted. From 9/1996 to 7/1997 there were 40 patients included in the study with an operated ankle fracture as monotrauma. Six weeks postoperatively the patients with cast treatment showed significantly higher functional deficits for the upper ankle joint (20%), the lower ankle joint (40%) and muscle atrophy (2.1 cm side difference) than the group with the vacuum stabilizing system (upper ankle joint 15%, lower ankle joint 25%, 1.4 cm muscle atrophy). Five patients out of the group with the vacuum system were already at work three weeks postoperatively. Three months postoperatively the functional results for both groups were approximating. The vacuum stabilizing system Vacoped offers better early functional results than conventional cast treatment after osteosynthesis of ankle fractures. Because of the increased patient comfort and the early ability for physical therapy the vacuum stabilizing system is preferable to cast treatment. In a randomised prospective controlled trial of 52 patients aged 16 to 65 we compared early non-weightbearing ankle mobilisation with ankle immobilisation following surgical treatment of bimalleolar ankle fractures. At 3 months there was no significant difference between the two groups in the range of ankle movements or pain. There was however a significant difference in the gait pattern with a higher proportion of cases in the early ankle mobilisation group having a symmetrical gait (P = 0.0001). We undertook a trial on 60 patients with AO 31A2 fractures of the hip who were randomised after stabilisation of the fracture into two equal groups, one of which received post-operative treatment using a non-invasive interactive neurostimulation device and the other with a sham device. All other aspects of their rehabilitation were the same. The treatment was continued for ten days after operation. Outcome measurements included the use of a visual analogue scale for pain, the brief pain inventory and Ketorolac for post-operative control of pain, and an overall assessment of outcome by the surgeon. There were significantly better results for the patients receiving treatment by active electrical stimulation (repeated measures analysis of variance, p < 0.001). The findings of this pilot trial justify a larger study to determine if these results are more generally applicable. From 1993 through 1996, a multicenter study was conducted on the surgical treatment of patients with posttraumatic recurrent anterior shoulder dislocations. Fifty-six patients (40 men, 16 women; mean age 26 years [range 18-51 years]), were evaluated with shoulder arthroscopy. If a Bankart lesion was present, the patients were randomly allocated to either an arthroscopic reconstruction with the use of biodegradable tacks or an open reconstruction with suture anchors. The postoperative rehabilitation protocol for the two groups was identical. In all patients, the range of shoulder motion, stability, and the Constant and Rowe scores were evaluated at 3, 12, and 24 months postoperatively. Thirty patients were surgically treated with the arthroscopic technique and 26 patients with the open technique. In the arthroscopic group, there were recurrences in 7 (23%) of 30 patients at a mean of 13 months (range 5 to 21 months) after surgery. All patients with stable shoulders had a negative apprehension test result. In the open group, there were recurrences in 3 (12%) of 26 patients at a mean of 10 months (range 2 to 23 months) after surgery (P = not significant). In the arthroscopic group, 2 patients had new traumatic redislocations, whereas 1 patient redislocated during an epileptic seizure. In the open group, 1 traumatic redislocation occurred. The 2-year results in this study demonstrate a large number of redislocations after reconstruction, even in the open surgery group. Patient noncompliance with the rehabilitation protocol and predisposing disease may partially explain these results. A tendency was seen toward more redislocations in the arthroscopic group, which emphasizes the importance of correct patient selection and careful surgical technique in the difficult surgical procedure. In a monocenter randomized controlled trial, 45 patients with isolated malleolar fracture type OTA/AO 44 A1-B2 undergoing ORIF were allocated randomly to a postoperative treatment either with a vacuum-stabilized orthesis with prescribed full weight bearing after the second week (23 patients) (orthesis group -- OG) or with functional aftertreatment with partial weight bearing of 15 kg for 6 weeks (22 patients) (control group -- CG). Outcomes were compared at 6- and 10-week follow-up examinations. The Olerud and Molander ankle (OMA) score, ankle swelling, usage of crutches, range of motion, Short Form 12, patient-reported visual analogue scales (VAS) (pain, comfort, walking confidence) and time to return to work were evaluated. All patients of OG showed reduced swelling at discharge. The median OMA scores after 6 weeks were 42 and 42.5 (p = 0.46) and after 10 weeks 69 and 72 (p = 0.55) in the OG and CG, respectively. The time to achieve secure walking capacity was reduced by 1 day (p = 0.03) in the OG. After ORIF of simple malleolar fractures, patients with a vacuum-stabilized orthesis can bear full weight 2 weeks postoperatively. This group experienced no adverse events. Postoperative swelling was significantly reduced and of the ability to walk on stairs confidently was shorter as compared to a functional aftertreatment without any external stabilization of the ankle. In a prospective randomised trial between September 1989 and June 1990 one hundred patients with per- and subtrochanteric fractures were consecutively treated by gamma-nail or DHS. The average age of both groups was about 80 years. The operation time for gamma-nailing was longer than for DHS implantation and also the postoperative blood loss was higher in the gamma-nail group. We found no difference of intraoperative blood loss, of perioperative lethality and in duration of hospital care. 90% of gamma-nail patients and 80% of DHS patients were successfully able to walk four days after operation with full weight bearing on the operated limb. Three patients in the DHS group with unstable fractures got cranial perforation of the cephalic screw mobilisation. Five patients of the gamma-nail group were reoperated, one case because of missed distal locking, one because of cranial perforation of the cephalic screw after varus dislocation of the proximal fragment. One patient suffered intraoperatively a proximal femur shaft fracture which was corrected during operation. In one case a wound hematoma was evacuated, an other patient needed secondary wound closure. Despite technical imperfection of implant and instruments, we conclude that the gamma-nail allows a very high percentage early and full weight bearing immediately after operation. So we consider that in the treatment of unstable pertrochanteric fractures of geriatric patients, the gamma-nail has proven to be more efficient than the DHS. We performed a prospective, randomised study on 57 patients older than 60 years of age with unstable, extra-articular fractures of the distal radius to compare the outcome of immobilisation in a cast alone with that using supplementary, percutaneous pinning. Patients treated by percutaneous wires had a statistically significant improvement in dorsal angulation (mean 7 degrees), radial length (mean 3 mm) and radial inclination (mean 3 mm) at one year. However, there was no significant difference in functional outcome in terms of pain, range of movement, grip strength, activities of daily living and the SF-36 score except for an improved range of movement in ulnar deviation in the percutaneous wire group. One patient developed a pin-track infection which required removal of the wires at two weeks. We conclude that percutaneous pinning of unstable, extra-articular fractures of the distal radius provides only a marginal improvement in the radiological parameters compared with immobilisation in a cast alone. This does not correlate with an improved functional outcome in a low-demand, elderly population. To investigate whether early therapy with a novel robotic device can reduce motor impairment and enhance functional recovery of poststroke patients with hemiparetic and hemiplegic upper limb.
                A single-blind randomized controlled trial, with an 8-month follow-up.
                Neurologic department and rehabilitation hospital.
                Thirty-five patients with acute (< or =1 wk of onset), unilateral, ischemic embolic, or thrombotic stroke.
                Patients of both groups received the same dose and length per day of standard poststroke multidisciplinary rehabilitation. Patients were randomly assigned to 2 groups. The experimental group (n=17) received additional early sensorimotor robotic training, 4 hours a week for 5 weeks; the control group (n=18) was exposed to the robotic device, 30 minutes a week, twice a week, but the exercises were performed with the unimpaired upper limb. Training by robot consisted of peripheral manipulation of the shoulder and elbow of the impaired limb, correlated with visual stimuli.
                The Fugl-Meyer Assessment (FMA) of upper-extremity function (shoulder/elbow and coordination and wrist/hand subsections) to measure each trained limb segment; the Medical Research Council (MRC) score to measure the strength of muscle force during 3 actions: shoulder abduction (MRC deltoid), elbow flexion (MRC biceps), and wrist flexion (MRC wrist flexors); the FIM instrument and its motor component; and the Trunk Control Test (TCT) and Modified Ashworth Scale (MAS).
                Compared with the patients in the control group, the experimental group showed significant gains in motor impairment and functional recovery of the upper limb after robot therapy, as measured by the MRC deltoid (P< or =.05) and biceps (P<.05) scores, the FMA for the proximal upper arm (P<.05), the FIM instrument (P<.05), and the FIM motor score (P<.01); these gains were also sustained at the 3- and 8-month follow-up. The FMA and MRC wrist flexor test findings did not differ statistically either at the end of training or at the follow-up sessions. We found no significant differences in MAS and TCT in either group in any of the evaluations. No adverse effects occurred and the robotic approach was very well accepted.
                Patients who received robotic therapy in addition to conventional therapy showed greater reductions in motor impairment and improvements in functional abilities. Robotic therapy may therefore effectively complement standard rehabilitation from the start, by providing therapeutic support for patients with poststroke plegic and paretic upper limb.
There is limited evidence supporting early commencement of weight-bearing and the use of a removable type of immobilisation to allow exercise during the immobilisation period after surgical fixation. Because of the potential increased risk of adverse events, the patient's ability to comply with the use of a removable type of immobilisation to enable controlled exercise is essential. There is little evidence for rehabilitation interventions during the immobilisation period after conservative orthopaedic management and no evidence for stretching, manual therapy or exercise compared to usual care following the immobilisation period. Small, single studies showed that some electrotherapy modalities may be beneficial. More clinical trials that are well-designed and adequately-powered are required to strengthen current evidence.
