There are no randomised trials comparing internal fixation and hemiarthroplasty for a displaced intracapsular femoral neck fracture in relation to mental state.
                To establish what should be the treatment of first choice, a prospective randomised clinical study was performed on 60 demented patients with displaced intracapsular femoral neck fractures, comparing internal fixation (n = 31) with hemiarthroplasty (n = 29).
                There was no significant difference in the mortality rate of both groups. Hemiarthroplasty was associated with significantly more loss of blood and more wound complications. Reoperation for secondary displacement of the fracture after internal fixation occurred in four patients. Although not-statistically significant, failure of internal fixation seemed to be higher after an inadequate osteosynthesis.
                Postoperative mortality is high and the chance of successful rehabilitation very small for both types of treatment in this group of patients. In our opinion, demented patients should not be treated with a major surgical procedure like hemiarthroplasty. Internal fixation should be considered the treatment of choice, because it is a smaller operation than prosthetic replacement, with less morbidity. If adequate reduction can not be achieved, a primary hemiarthroplasty should be performed. 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. Orthopaedic surgeons vary in their management of displaced intracapsular fractures of the hip in healthy older patients. The aim of this investigation was to determine the functional, clinical, and resource consequences of three different types of surgical treatment.
                The study was a multicenter randomized controlled trial. Reduction and fixation was compared with bipolar hemiarthroplasty with cement and total hip replacement with cement. Participating surgeons elected to randomize their patients to be treated with either one of the three types of procedures or with either fixation or bipolar hemiarthroplasty. Functional outcomes were measured with a hip-rating questionnaire and the EuroQol health status measure. Clinical outcomes included mortality and complications. The direct health service costs were compared. Participants were followed up for two years.
                Two hundred and seven patients were randomized to be treated with one of the three operations, and ninety-one were randomized to be treated with either fixation or bipolar hemiarthroplasty. There were no differences in the mortality rates among the treatment groups. The rate of secondary surgery was highest in the fixation group (39% compared with 5% in the group treated with bipolar hemiarthroplasty and 9% in the group treated with total hip replacement). The fixation group had the worst hip-rating-questionnaire and EuroQol scores at four and twelve months. The total hip replacement group had significantly better functional outcome scores at twenty-four months than the other two groups. Although fixation was initially the least costly procedure, this short-term advantage was eroded by significantly higher costs for subsequent hip-related hospital admissions.
                Arthroplasty is more clinically effective and cost-effective than reduction and fixation in healthy older patients with a displaced intracapsular fracture of the hip. The long-term results of total hip replacement may be better than those of bipolar hemiarthroplasty. 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. We randomised prospectively 44 patients with fractures of the shaft of the humerus to open reduction and internal fixation by either an intramedullary nail (IMN) or a dynamic compression plate (DCP). Patients were followed up for a minimum of six months. There were no significant differences in the function of the shoulder and elbow, as determined by the American Shoulder and Elbow Surgeons' score, the visual analogue pain score, range of movement, or the time taken to return to normal activity. There was a single case of shoulder impingement in the DCP group and six in the IMN group. Of these six, five occurred after antegrade insertion of an IMN. In the DCP group three patients developed complications, compared with 13 in the IMN group. We had to perform secondary surgery on seven patients in the IMN group, but on only one in the DCP group (p = 0.016). Our findings suggest that open reduction and internal fixation with a DCP remains the best treatment for unstable fractures of the shaft of the humerus. Fixation by IMN may be indicated for specific situations, but is technically more demanding and has a higher rate of complications. A total of 455 patients aged over 70 years with a displaced intracapsular fracture of the proximal femur was randomised to be treated either by hemiarthroplasty or internal fixation. The preoperative characteristics of the patients in both groups were similar. Internal fixation has a shorter length of anaesthesia (36 minutes versus 57 minutes, p < 0.0001), lower operative blood loss (28 ml versus 177 ml, p < 0.0001) and lower transfusion requirements (0.04 units versus 0.39 units, p < 0.0001). In the internal fixation group 90 patients required 111 additional surgical procedures while only 15 additional operations on the hip were needed in 12 patients in the arthroplasty group. There was no statistically significant difference in mortality between the groups at one year (61/226 versus 63/229, p = 0.91), but there was a tendency for an improved survival in the older less mobile patients treated by internal fixation. For the survivors assessed at one, two and three years from injury there were no differences with regard to the outcome for pain and mobility. Limb shortening was more common after internal fixation (7.0 mm versus 3.6 mm, p = 0.004). We recommend that displaced intracapsular fractures in the elderly should generally be treated by arthroplasty but that internal fixation may be appropriate for those who are very frail. A prospective randomised trial of surgical treatment for the displaced subcapital femoral fracture in patients of 70 years or more is presented. Two hundred and eighteen patients were randomly allocated into one of three treatment groups: manipulative reduction and internal fixation using Garden screws; Thompson hemiarthroplasty through a posterior (Moore) approach; and Thompson hemiarthroplasty through an anterolateral (McKee) approach. There is no significant difference in the mortality of the internal fixation and posterior arthroplasty groups. Both groups showed a significantly higher mortality than patients operated on through the anterior approach. The technical results of operation were worse in the internally fixed group, with only 40 per cent being satisfactory. Mobilisation was best achieved after the posterior approach. It is concluded that Thompson hemiarthroplasty, using an anterolateral approach, is the safest operation in this group of patients. One hundred and thirty-eight patients with a closed grade-4 supination-external rotation or pronation-external rotation ankle fracture (Lauge-Hansen classification) who were seen in the emergency room of the University of Chicago Hospitals were entered into a randomized study of the results of various methods of treatment. Ninety-six patients with satisfactory initial closed reduction were randomized between continued closed treatment in a plaster cast and open reduction with rigid internal fixation according to the techniques of the Association for the Study of Internal Fixation (ASIF). Forty-two patients with unsatisfactory closed reduction were randomized between open reduction with internal fixation of only the medial malleolus and open reduction with rigid internal fixation according to the ASIF techniques. Of the 138 patients who were admitted to the study, only seventy-one (51 per cent) could be followed for an average of 3.5 years (a typical return rate of urban trauma centers). The outcomes were evaluated by a scoring system that included clinical, anatomical, and arthritis scores. Statistical analysis of the data showed that, of the patients with initial satisfactory closed reduction, the ones treated by open reduction and rigid internal fixation had significantly higher total scores, particularly the patients who were more than fifty years old and those with a medial malleolar fracture. The small number of patients with unsatisfactory closed reduction who were treated by one of the two types of open reduction and internal fixation and were available for follow-up precluded drawing any conclusions about the superiority of one method of internal fixation over the other in that group. The difference in the talocrural angle between the injured and normal sides was the only statistically significant radiographic indicator of a good prognosis. We studied 60 patients with an acute displaced fracture of the femoral neck and with a mean age of 84 years. They were randomly allocated to treatment by either internal fixation with cannulated screws or hemiarthroplasty using an uncemented Austin Moore prosthesis. All patients had severe cognitive impairment, but all were able to walk independently before the fracture. They were reviewed at four, 12 and 24 months after surgery. Outcome assessments included complications, revision surgery, the status of activities of daily living (ADL), hip function according to the Charnley score and the health-related quality of life (HRQOL) according to the Euroqol (EQ-5D) (proxy report). General complications and the rate of mortality at two years (42%) did not differ between the groups. The rate of hip complications was 30% in the internal fixation group and 23% in the hemiarthroplasty group; this was not significant. There was a trend towards an increased number of re-operated patients in the internal fixation group compared with the hemiarthroplasty group, 33% and 13%, respectively (p = 0.067), but the total number of surgical procedures which were required did not differ between the groups. Of the survivors at two years, 54% were totally dependent in ADL functions and 60% were bedridden or wheelchair-bound regardless of the surgical procedure. There was a trend towards decreased mobility in the hemiarthroplasty group (p = 0.066). All patients had a very low HRQOL even before the fracture. The EQ-5D(index) score was significantly worse in the hemiarthroplasty group compared with the internal fixation group at the final follow-up (p < 0.001). In our opinion, there is little to recommend hemiarthroplasty with an uncemented Austin Moore prosthesis compared with internal fixation, in patients with severe cognitive dysfunction. Although the use of a sliding hip screw is considered to be the preferred treatment for pertrochanteric femoral fractures, we theorized that external fixation could produce clinical outcomes equal to, if not better than, the outcomes obtained with conventional treatment. Furthermore, because external fixation is minimally invasive, we expected a lower rate of morbidity and a reduced need for blood transfusions. Therefore, we compared the two treatments in a clinical trial of elderly patients with pertrochanteric fracture.
                Forty consecutive elderly female patients who had a pertrochanteric fracture were randomized to be treated with either fixation with a 135 degrees four-hole sliding hip screw (Group A) or an external fixation device with hydroxyapatite-coated pins (Group B). The inclusion criteria were female gender, an age of at least sixty-five years, an AO/OTA type-A1 or A2 fracture, and a bone mineral density T-score of less than -2.5. There were no differences in patient age, fracture type, bone mineral density, comorbidities, length of hospital stay, or quality of reduction between the two groups.
                The average intraoperative time (and standard deviation) was 64 +/- 6 minutes in Group A and 34 +/- 5 minutes in Group B (p < 0.005). The average number of units of blood transfused postoperatively was 2.0 +/- 0.1 in Group A and none in Group B (p < 0.0001). Group B had less pain five days postoperatively (p < 0.05). Varus collapse of the fracture at six months averaged 6 degrees +/- 8 degrees in Group A and 2 degrees 1 degrees in Group B (p < 0.002). No pin-track infections occurred in Group B. The average Harris hip score at six months was 62 +/- 19 points in Group A and 63 +/- 17 points in Group B.
                This study showed that external fixation with hydroxyapatite-coated pins is an effective treatment for this fracture in this patient population. The operative time is brief, the blood loss is minimal, the fixation is adequate, and the reduction is maintained over time. To compare the surgical complications and functional outcome of the Gamma nail intramedullary fixation device versus the Richards sliding hip screw and plate device in intertrochanteric femoral fractures.
                A prospective, randomised controlled clinical trial with observer blinding.
                A regional teaching hospital in the United Kingdom.
                All patients admitted from the local population with intertrochanteric fractured femurs were included. There were 400 patients entered into the study and 399 followed-up to one year or death.
                The devices were assigned by randomization to either a short-type Gamma nail (203 patients) or a Richard's-type sliding hip screw and plate (197 patients).
                The main surgical outcome measurements were fixation failure and reoperation. A functional outcome of pain, mobility status, and range of movement were assessed until one year.
                The requirement for revision in the Gamma nail group was twelve (6%); for Richard's group, eight (4%). This was not statistically different (p = 0.29; odds ratio, 1.48 [0.59-3.7]). A subcapital femoral fracture occurred in the Richard's group. Femoral shaft fractures occurred with four in the Gamma nail group (2%) and none in the Richard's group (p = 0.13). Three required revision to another implant. Lag-screw cut-out occurred in eight patients in the gamma nail group (4%) and four in the Richard's group (2%). This was not statistically significant (p = 0.37; odds ratio, 2.29 [0.6-9.0]). The development of other postoperative complications was the same in both groups. There was no difference between the two groups in terms of early or long-term functional status at one year.
                The use of an intramedullary device in the treatment of intertrochanteric femoral fractures is still associated with a higher but nonsignificant risk of postoperative complications. Routine use of the Gamma nail in this type of fracture cannot be recommended over the current standard treatment of dynamic hip screw and plate. 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. 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 trial comparing three treatments for displaced intracapsular fractures of the hip in 280 patients aged 65 to 79 years. The mean patient survival was significantly higher in the group undergoing reduction and internal fixation (79 months) compared with that with a cemented Thompson hemiarthroplasty or a cemented Monk bipolar hemiarthroplasty (61 months and 68 months, respectively). After three years, 32 of 93 patients (34.4%) who had undergone fixation had local complications, necessitating further intervention in 28 (30%). There were no significant differences in the functional outcome in survivors, who were reviewed annually to five years. Either reduction and internal fixation or cemented hemiarthroplasty may be offered as alternative treatments for a displaced intracapsular fracture in a mobile and mentally competent patient under the age of 80 years. The choice of procedure by the patient and the surgeon should be determined by the realisation that the use of internal fixation is associated with a 30% risk of failure requiring further surgery. If this is accepted, however, hemiarthroplasty is avoided, which, in our study has a significantly shorter mean survival time. The use of a bipolar prosthesis has no significant advantage. The objective of this study was to determine the effect of different prosthetic systems on the functional and radiographic outcomes after shoulder arthroplasty for fractures. This study comprised 35 patients (28 women and 7 men) with a mean age of 74 years (range, 56-88 years) who sustained 4-part fractures of the proximal humerus and were randomly allocated to 2 different groups regarding the type of prosthesis. The 2 systems used differ mainly in the type of fixation of the tuberosities. In group 1 (EPOCA), the fixation was achieved with wire cables through a medial and a lateral hole in the stem, whereas in group 2 (HAS), the fixation was performed by use of transosseous braided sutures. After a follow-up of 1 year, the functional and radiographic outcomes were evaluated. The retrieved data demonstrate that rigid fixation and anatomic positioning of the tuberosities (group 1) increase the rate of bony healing superior to all other factors. There was a statistically significant difference regarding the relative individual Constant score (P = .001) and the mean active range of motion (flexion, P < .001; abduction, P = .001; external rotation in adduction, P = .01; and external rotation in 90 degrees abduction, P = .001) when both groups were compared, showing a better outcome in the EPOCA group for all parameters. Radiologic findings, like heterotopic ossification, glenoid erosion, or subluxation, had no significant influence on the outcome in this study. Accurate placement of the tuberosities and healing at the bone-bone interface of the rotator cuff seem to be the most important factors influencing the outcome in prosthetic care of fractures. The aim of this study was to compare the results of the humerus intramedullary nail (IMN) and dynamic compression plate (DCP) for the management of diaphyseal fractures of the humerus. Forty-seven patients with diaphyseal fracture of the shaft of the humerus were randomised prospectively and treated by open reduction and internal fixation with IMN or DCP. The criteria for inclusion were grade 1 or 2a compound fractures, polytrauma, early failure of conservative treatment and unstable fractures. The patients with pathological fractures, grade 3 open fractures, refractures and old neglected fractures of the humerus were excluded from the study. Twenty-three patients underwent internal fixation by IMN and 24 by DCP. Reamed antegrade nailing was done in all cases. DCP was done through an anterolateral or posterior approach. The outcome was assessed in terms of the union time, union rate, functional outcome and the incidence of complications. Functional outcome was assessed using the American Shoulder and Elbow Surgeons' Score (ASES). On comparing the results by independent samples t test, there was no significant difference in ASES scores between the two groups (P>0.05). The average union time was found to be significantly lower for IMN as compared to DCP (P<0.05). The union rate was found to be similar in both groups. Complications such as infection were found to be higher with DCP as compared to IMN, while shortening of the arm (1.5-4 cm) and restriction of shoulder movements due to impingement by the nail were found to be higher with IMN as compared to DCP. However, this improved in all patients following the removal of the nail once the fracture had healed. This study proves that IMN can be considered a better surgical option for the management of diaphyseal fractures of the humerus as it offers a short union time and lower incidence of serious complications like infection. However, there appears to be no difference between the two groups in terms of the rate of union and functional outcome. We compared the efficacy of a load-sharing device, the Medoff sliding plate (MSP), with that of 3 other load-bearing screw-plate devices for the fixation of subtrochanteric fractures in a randomized multicenter trial of 107 elderly patients. 55 fractures were operated on with the MSP, and 52 with the dynamic hip screw (DHS) with or without a trochanteric stabilizing plate (TSP) or with the dynamic condylar screw (DCS). The patient material in the groups was similar regarding age, domestic situation, preinjury walking ability and fracture types. We followed the patients clinically and radiographically for a minimum of 1 year. There was no significant difference in walking ability or return rate to the home at follow-up. Fixation failure occurred in 1/55 fractures operated on with the MSP, in 3/32 with the DHS, in 3/12 with the DCS and in 2/8 with the DHS/TSR The difference in the rate of fixation failure was statistically significant, when the MSP group was compared to the 3 load-bearing devices in the other group (1 vs 8). On the basis of this experience, we think that the load-sharing principle of the MSP, which seems to facilitate fracture impaction and stability, appears to be a good alternative in extramedullary fixation of subtrochanteric fractures. To compare clinical and radiological results in per- and subtrochanteric fractures' management with 90 degrees blade plate or Gamma nail fixation; an implant allowing early weight-bearing and fracture healing in correct position remains still difficult.
                Between 1993 and 1995, 26 patients addressed to our Center for a Kyle IV [1] fracture were divided into 2 groups, one fixed with blade plate and the other with Gamma nail. The follow-up for all patients is 12 months.
                Gamma nail allows early weight-bearing in all patients, fracture healing is acquired at 4.2 months; an operative diaphyseal fracture needed conversion to a long Gamma nail. We observed a slight cut-out that didn't need reoperation. In the blade plate group, we noticed three femoral head necrosis without major flattening, two non-unions, one plate's breakage and two malunions; fracture healing is acquired at 6.3 months. The two non-unions and the plate's breakage didn't need reoperation because of low functional demand.
                We prefer Gamma nail in per- and subtrochanteric femoral fractures' management, it allows early and fast weight-bearing and fracture healing is acquired in all cases. 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. Unstable intertrochanteric fractures in elderly patients are associated with a high rate of complications. The purpose of this investigation was to compare the results of long-stem cementless calcar-replacement hemiarthroplasty with those of treatment with a proximal femoral nail for unstable intertrochanteric fractures in elderly patients.
                Fifty-eight elderly patients with an AO/OTA type 31-A2 intertrochanteric fracture of the femur were randomized into two treatment groups and were followed for a minimum of two years. The twenty-nine patients in Group I were treated with a long-stem cementless calcar-replacement prosthesis, and the twenty-nine patients in Group II were treated with a proximal femoral nail. The two treatment groups were comparable with regard to demographic and injury variables.
                There were no significant differences between the groups in terms of functional outcomes, hospital stay, time to weight-bearing, or general complications. Patients treated with a proximal femoral nail had a shorter operative time, less blood loss, fewer units of blood transfused, a lower mortality rate, and lower hospital costs compared with those treated with the long-stem cementless calcar-replacement prosthesis.
                In elderly patients with an unstable intertrochanteric femoral fracture, a proximal femoral nail provides superior clinical outcomes but no advantage with regard to functional outcome when compared with a long-stem cementless calcar-replacement arthroplasty.
                Therapeutic Level I. In this prospective randomised trial we compare the mortality, morbidity and functional results of patients following each of the three principal methods of treatment for displaced subcapital fractures of the femur. Two hundred and ninety patients over the age of 65 years were included and randomly allocated to undergo closed reduction and internal fixation with a sliding compression screw plate or uncemented Austin Moore hemiarthroplasty or cemented Howse II total hip arthroplasty (THA). Nineteen patients were subsequently excluded. The 13 year results show that there was no statistical difference in the mortality between the three groups (81, 85 and 91% respectively). Internal fixation and hemiarthroplasty groups fared poorly with a revision rate of 33 and 24%, respectively, compared with 6.75% in the THA group. The dislocation rate was 13% following hemiarthroplasty and 20% following THA. Average Harris hip scores were 62, 55 and 80, respectively, for the internal fixation, hemiarthroplasty and THA groups. In the long term, both internal fixation and hemiarthroplasty resulted in a poor outcome with respect to pain and mobility. Despite high early complications, THA resulted in least pain and most mobility both in the short and long-term and was encouraging with a revision rate of only 6.25%. THA should be seriously considered in physiologically active patients with a displaced subcapital fracture of the femur. We performed a prospective study on 96 patients with extra-articular or intra-articular fractures of the distal radius with a dorsally displaced posteromedial fragment. After closed reduction, we compared trans-styloid fixation and immobilisation with Kapandji fixation and early mobilisation. Forty-two patients of mean age 57.1 years +/- 18.1 (SD) were treated by trans-styloid K-wire fixation and 45 days of short-arm cast immobilisation. Fifty-four patients of mean age 57.7 years +/- 18.7 (SD) had Kapandji fixation and immediate mobilisation according to the originator. All the patients had clinical and radiological review at about six weeks and at 3, 6, 12 and 24 months after the operation. Pain, range of movement and grip strength were tested clinically, and changes in dorsal tilt, radial tilt, ulnar variance, and radial shortening were assessed radiologically. Statistical analysis was applied to comparisons with the normal opposite wrist. Pain and reflex sympathetic dystrophy were more frequent after Kapandji fixation and early mobilisation, but the range of motion was better although this became statistically insignificant after six weeks. The radiological reduction was better soon after Kapandji fixation, but there was some loss of reduction and increased radial shortening during the first three postoperative months. The clinical result at two years was similar in both groups.
There is insufficient evidence to inform the management of these fractures. Early physiotherapy, without immobilisation, may be sufficient for some types of undisplaced fractures. It remains unclear whether surgery, even for specific fracture types, will produce consistently better long term outcomes but it is likely to be associated with a higher risk of surgery-related complications and requirement for further surgery.
There is insufficient evidence to establish what is the best method of surgical treatment, either in terms of the use of different categories of surgical intervention (such as plate versus nail fixation, or hemiarthroplasty versus tension-wire fixation) or different methods of performing an intervention in the same category (such as different methods of plate fixation). There is insufficient evidence to say when to start mobilisation after either surgical fixation or hemiarthroplasty.
