Prospective randomized comparison between a dynamic hip screw and a mini-invasive static nail in fractures of the trochanteric area: preliminary results.
A randomized comparison was made of condylocephalic (Ender) nails and a nail-plate technique (McLaughlin) for fixation of trochanteric fractures, to evaluate the consumption of acute hospital bed-days, number of reoperations, peroperative blood loss, and operation time. Reoperations were performed in 30% of the Ender group and in 10% of the McLaughlin group and blood loss was doubled for the McLaughlin method. Our study has shown, that in our hands, patients operated on with Ender nails had more reoperations, but in spite of this the total cost, in the form of days in hospital or operation time was not increased. 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. Controversy exists with regard to whether to treat AO/OTA 31-A2 fractures of the proximal part of the femur with an intramedullary device or an extramedullary device. A prospective, randomized, controlled trial was performed to compare the outcome of treatment of these unstable fractures of the proximal part of the femur with either a sliding hip screw or a long gamma nail.
                Two hundred and ten patients presenting with an AO/OTA 31-A2 fracture of the proximal part of the femur were randomized, at the time of admission, to fixation with use of either a long gamma nail or a sliding hip screw. The primary outcome measure was reoperation within the first postoperative year. Secondary measures included mortality, length of hospital stay, transfusion rate, change in mobility and residence, and quality of life as measured with the EuroQol 5D outcome score.
                There was no significant difference between the reoperation rates for the two groups. In total, five patients (three from the long-gamma-nail group and two from the sliding-hip-screw group) underwent revision surgery because of cut-out. Tip-apex distance was found to correlate with the implant cut-out rate. There was no significant difference between the two groups in terms of the EuroQol 5D outcome scores, the mortality rates after correction for the mini-mental score, or any of the secondary outcome measures.
                When compared with the long gamma nail, the sliding hip screw should remain the gold standard for the treatment of AO/OTA 31-A2 fractures of the proximal part of the femur because it is associated with similar outcomes with less expense. To compare the results between a sliding compression hip screw and an intramedullary nail in the treatment of pertrochanteric fractures.
                Prospective computer-generated randomization of 206 patients into two study groups: those treated by sliding compression hip screw (Group 1; n = 106) and those treated by intramedullary nailing (Group 2; n = 100).

                All patients over the age of fifty-five years presenting with fractures of the trochanteric region caused by a low-energy injury, classified as AO/OTA Type 31-A1 and A2.
                Treatment with a sliding compression hip screw (Dynamic Hip Screw; Synthes-Stratec, Oberdorf, Switzerland) or an intramedullary nail (Proximal Femoral Nail; Synthes-Stratec, Oberdorf, Switzerland).
                Intraoperative: operative and fluoroscopy times, the difficulty of the operation, intraoperative complications, and blood loss. Radiologic: fracture healing and failure of fixation. Clinical: pain, social functioning score, and mobility score.
                The minimum follow-up was one year. We did not find any statistically significant difference, intraoperatively, radiologically, or clinically, between the two groups of patients.
                There is no advantage to an intramedullary nail versus a sliding compression hip screw for low-energy pertrochanteric fractures AO/OTA 31-A1 and A2, specifically with its increased cost and lack of evidence to show decreased complications or improved patient outcome. 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. The purpose of this study is to compare a cephalomedullary nail that uses a piriformis fossa starting point to one that uses a trochanteric starting point, in the treatment of high-energy proximal femur fractures in young patients. Our hypothesis was that a nail that uses a trochanteric starting point would result in less blood loss than a nail that uses a piriformis fossa starting point.
                Prospective, randomized.
                Level 1 trauma center.
                Thirty-four consecutive patients aged between 18 and 50 years who sustained a subtrochanteric, intertrochanteric, or ipsilateral femoral neck/shaft fracture due to a high-energy injury were enrolled.
                Patients were randomized to have their fractures repaired with a Russell-Taylor Recon Nail or Howmedica Long Gamma Nail. Surgery was performed on a fracture table, in supine or lateral position according to the surgeon's preference. Direct fracture exposure was avoided. Reduction was obtained through traction, patient positioning, and manual pressure. If necessary, stab-wound incisions were made to introduce instruments to improve reduction. Intramedullary reamers were used, and all nails were statically locked. Bone grafting was not used.
                Blood loss, incision length, duration of surgery, and body mass index were recorded for each patient. Surgeon's assessment of ease of use of the device and quality of reduction were noted. Patients were to be followed up to assess fracture union. Hip and knee ranges of motion at latest follow-up were measured. Radiographs obtained at the time of union were assessed for varus malalignment. Return to work status was recorded, and the Harris Hip Score was used to assess hip function.
                There were 17 patients in each group. The 2 groups did not differ with regard to blood loss, incision length, and duration of surgery or intraoperative complications. Body mass index was significantly linked to duration of surgery (P<0.001) and incision length (P<0.001). Surgeon's assessment of ease of use and reduction quality for the two devices did not differ. The rate of varus malunion did not differ between the 2 groups. Two patients were lost to follow-up before fracture union. All other fractures healed with no need for bone grafting or other procedures to obtain union. One obese patient developed a wound infection that resolved after debridement and a course of antibiotics. A total of 6 patients were lost prior to their 1-year follow-up visit. Among the remaining 28 patients, at an average follow-up of 14 months, no difference was noted between the 2 groups with regard to return to work status, Harris Hip Score, or hip and knee ranges of motion.
                Both devices yield predictably good results in these difficult fractures. We found no difference between the two devices with regard to incision length, duration of surgery, blood loss, reduction, ease of use, union rate, complication rate, or outcome. Intramedullary nailing has been the gold standard in the management of lower limb fractures by virtue of advantage of early joint mobilisation and weight bearing. They are being increasingly used in the peri-trochanteric fractures of femur. Biomechanical studies have proved the supremacy of single femoral neck screw construct over two femoral neck screws along with the intramedullary nails in osteoporotic bones due to lower incidence of complications. This randomised clinical trial was conducted to study the clinico-radiological outcome of single and two-femoral neck screw construct in the management of unstable trochanteric fractures in the elderly osteoporotic bones. Although there was no significant difference in the clinical outcome in the two groups, less sliding of the femoral neck screws was noted with two-femoral neck screw configuration. The tip-apex distance was also significantly lower in the two-screw construct compared to that of the single screw construct. This study to our knowledge is the first randomised control clinical trial evaluating the effectiveness of one and two femoral neck screw configuration of intra-medullary nails in the management of unstable trochanteric fractures. The current prospective and randomized study was done to determine whether fixation of intertrochanteric femoral fractures that lack a medial buttress with a dynamically locked intramedullary hip screw prevents proximal stress shielding. Stress shielding was evident by the presence of cortical hypertrophy at the level of the tip of the nail and often was associated with midthigh pain. Of the 80 patients enrolled in this trial, 64 still were alive after 1 year. Among these patients, 30 had the nail classically locked with two screws transfixing the nail in two separate holes (Group A), and 34 had the nail locked with one screw passing through a slot (Group B). The average duration of followup was 37 months (range, 12-49 months). Tolerance to dynamically locked nails was significantly better, with only one patient in Group B having cortical hypertrophy of the femur at the level of the tip of the nail, compared with six patients in Group A. Other outcomes were equal in both groups. Late tolerance to this new dynamically locked intramedullary hip screw is good, while retaining the known advantages of nailing of these fractures. This study aimed at comparing the results obtained with a sliding screw plate and an experimental device including a small-diameter nail that can be placed with a mini-invasive approach and provides a stable fixation.
                Randomized prospective study.
                University hospital.
                The study included two groups with thirty fractures of the trochanteric area.
                In both groups, the surgical procedure was carried out on patients placed on a traction table in a supine position, under an x-ray amplifier. Sliding screw plates (THS) were set in place according to the usual open technique. Nails were placed through a twenty-millimeter supratrochanteric cutaneous incision. This experimental system comprised a locked intramedullary nail with two nonparallel seven-millimeter cervicocephalic screws.
                The comparison between the two groups was based on the surgical procedure (time, duration of x-ray irradiation, and total blood loss); the initial postoperative period (complications, duration of hospital stay, and the time before returning home); the time before full weight bearing became effective; the functional and social recovery; mortality; and the quality of immediate and final anatomic restitution and healing.
                Operating time (p < 0.001) and blood loss (p < 0.001) were lower in the nail group, and no blood transfusion was required. Postoperative pain (p < 0.01), time necessary to support full weight bearing (p < 0.02), and time before returning home (p < 0.05) were reduced in the nail group. All fractures healed in the same amount of time, with good anatomic results in the nail group, whereas ten impactions beyond ten millimeters occurred in the plate group. No difference was found between the two groups in walking ability and autonomy recovery, but hip function (p < 0.05) was better in the nail group.
                This preliminary clinical study has shown the advantages of this mini-invasive technique. It could not evaluate all the possible disadvantages inherent in the method. These points will be evaluated in a multicenter study justified by these preliminary results.
Any advantages in intra-operative outcomes of condylocephalic nails are outweighed by the increase in fracture healing complications, reoperation rate, residual pain and limb deformity when compared with an extramedullary implant, particularly a sliding hip screw. The use of condylocephalic nails (in particular Ender nails), for trochanteric fracture is no longer appropriate.
