A preliminary experience with the Russell-Taylor reconstruction nail for complex femoral fractures.

Eleven cases of complex femoral fractures were seen from November 1987 to November 1989; five ipsilateral femoral neck and shaft fractures and six comminuted subtrochanteric fractures. High-energy accidents accounted for most of these injuries. There were numerous associated injuries, many requiring operative procedures. All of the fractures were treated with Russell-Taylor reconstruction nails. All fractures united, but there were two delayed unions. There was no delay in diagnosis of the femoral neck fractures, and all healed without avascular necrosis. Malalignment occurred in one case, shortening of the femur occurred in two cases, and in two cases only one screw could be placed in the femoral head. In three patients technical errors related to nail insertion led to fracture complications. The use of the Russell-Taylor reconstruction nail is technically demanding. However, we conclude that in complex femoral fractures, this device offers superior stabilization over other currently used methods of internal fixation.

Cephalomedullary interlocked nail for ipsilateral hip and femoral shaft fractures

A retrospective study of the management of 23 cases of ipsilateral hip and femoral shaft fractures, between January 1998 and December 2001, is presented. All except two cases were managed by a single implant, i.e. reconstruction nail. There was delayed diagnosis of femoral neck fracture in two cases where the "miss a nail" technique was used for fixation of the femoral neck fracture. All patients managed by reconstruction nail were simultaneously operated on for both fractures and operative treatment was executed as early as the general condition of the patient permitted. Delay in treatment was generally because of the associated injuries (head, chest or abdominal). There were 22 males and 1 female patient with an average age of 34.5 years. Average follow-up was 30.9 months. There was one case of non-union of the femoral neck fracture, one case of avascular necrosis and one femoral neck fracture united in varus. There were four cases of non-union and six cases of delayed union of femoral shaft fractures. Mean time for union of the femoral neck fracture was 15 weeks and for the shaft fracture was 22 weeks. In this series femoral shaft fracture determined the total union period. Complications involving the femoral shaft fracture were more common than those related to femoral neck fractures. Shaft complications were more manageable with or without secondary procedures as compared to femoral neck complications, which usually require more extensive procedures. This stresses the need to realise the significance and seriousness of both components of this complex injury, in evaluation, management and post-operative care. We conclude that, though technically demanding, reconstruction nail is an acceptable alternative for management of concomitant fractures of the femoral neck and shaft with acceptable rates of complications and good results.     

Ipsilateral femoral shaft and neck fractures: are cephalomedullary nails appropriate?

A retrospective review was conducted to examine rates of malreduction and nonunion in ipsilateral femoral neck and shaft fractures using different fixation strategies. Twenty-two consecutive patients with 23 fractures were identified. Participants were treated with various fixation strategies for ipsilateral femoral neck and shaft fractures. Cephalomedullary devices were used in 13 cases, while cannulated screws and a retrograde femoral nail were used in nine cases. One patient was treated with cannulated screws and external fixation of the femoral shaft. Radiographic assessment of the quality of reduction and union of both fractures was evaluated. Clinical and radiographic follow-up was available in 20 fractures (87%) with a mean of 12 months (range 3-50). Two femoral neck nonunions occurred; both had fair reductions of the fractures obtained by closed maneuvers, and two-device fixation was used in each. One femoral shaft nonunion occurred in a fracture treated with a cephalomedullary nail. All three united after revision surgery. No cases of osteonecrosis or conversion to hip arthroplasty were noted. A combination of retrograde femoral nailing and screw fixation of the femoral neck or placement of a cephalomedullary nail can provide excellent reduction and rate of union in the treatment of this injury pattern. Excellent reduction of the femoral neck fracture is key to preventing femoral neck nonunion.

Treatment of ipsilateral hip and femoral shaft fractures with reconstructive intramedullary interlocking nail

Objective: To evaluate the results of reconstructive intramedullary interlocking nail in the treatment of ipsllateral hip and femoral shaft fractures. Methods: From August 1997 to November 2001, 13 patients were treated with the reconstructive intramedullary interlocking nail. Nine patients were associated with ipsllateral femoral neck fractures, three with ipsilateral intertrochanteric fractures, and one with subtrochanteric fracture. Results: The follow-up time was from 6 to 38 months with an average of 14 months. All the femoral shaft and hip fractures healed up well. There was no nonunion of the femoral neck, and only one varns malunion. No patient had avascular necrosis of the femoral head. The average healing time for femoral neck fracture was 4.6 months and for shaft fracture 5.8 months. The joint movement and other functions were fairly resumed. Conclusions: The reconstructive intramedullary interlocking nail, with less trauma, refiable fixation, and high rate of fracture healing, is an ideal method of choice in the treatment of ipsilateral hip and femoral shaft fractures.

Ipsilateral fractures of the femoral neck and shaft.

Thirty-three patients with ipsilateral intracapsular femoral neck and shaft fractures were treated with antegrade reamed intramedullary (IM) nails and cancellous screw fixation of the femoral neck. The shaft fractures were fixed prior to definitive neck stabilization. A "reversed" nail construct was used in 13 patients, a conventional interlocked nail was used in 6, and a reconstruction nail was used in the remaining 14. Thirty-one (94%) of the femoral shaft fractures healed primarily. In two patients, the shaft fracture failed to unite and was bone grafted and plated, respectively; the fractures subsequently healed. However, only 27 (82%) of the femoral neck fractures healed after initial fixation. In six patients (18%), a symptomatic varus nonunion developed, requiring a valgus osteotomy. Five of the six femoral neck non-unions and all of the osteotomy sites united; however, two of these patients later developed osteonecrosis of their femoral heads. Closed reamed antegrade IM nailing with supplemental screw fixation of ipsilateral femoral neck and shaft fractures did not produce uniformly successful results because of high rates of varus nonunion of the femoral neck fracture.     

Antegrade nailing of femoral shaft fractures combined with neck or distal femur fractures

Introduction Complex femoral fractures pose considerable therapeutic challenges to orthopedic surgeons. We present a retrospective review of 25 patients with complex femoral fractures treated with intramedullary locked nailing and supplemental screw fixation.Materials and methods Fifteen patients with ipsilateral femoral neck and shaft fractures (group 1) and 10 patients with ipsilateral femoral shaft and distal femur fractures (group 2) were treated from 1990 to 1998. High-energy injuries occurred in all patients. There were 4 open fractures. Antegrade, locked nailing of diaphyseal fractures was performed in all cases. Supplemental screws for the neck were used in all patients in group 1 and in 3 patients in group 2.Results All of the fractures united during the follow-up. Five patients in group 1 underwent reoperation (33.3%): one due to a delayed union, the second due to an implant failure, the third due to a nonunion of a neck fracture, and the last two because of an initially missed femoral neck fracture. None of the patients in group 2 underwent reoperation. Angular malalignment of the shaft was found in 6 fractures in group 1 (average 4.8^o, range 3^o–11^o) and in 4 fractures in group 2 (average 6^o, range 3^o–12^o). Shortening of the limb occurred in 3 patients in group 1 (average 1.4 cm, range 1–1.8) and in 1 patient in group 2 (2 cm). Loss of fixation was seen in 1 patient in each group. Avascular necrosis and infection were not seen in any case in both groups.Conclusion Femoral intramedullary nails with antegrade or retrograde options for insertion and different locking possibilities have extended the indications to include both diaphyseal and metaphyseal fractures. New nail designs, usually more expensive than the conventional nails, have been introduced into the market for this purpose. One has to keep in mind that antegrade, locked nailing of femoral shaft fractures combined with neck or distal femur fractures is a technically demanding but efficacious procedure. The success rate is high when the technique is meticulously implemented.     

Treatment of ipsilateral femoral neck and shaft fractures with the Russell-Taylor reconstructive nail.

Twenty-seven ipsilateral femoral neck and shaft fractures were treated with the Russell-Taylor reconstructive nail. Follow-up ranged from 6-48 months (average: 23.6 months). Femoral neck fractures healed within an average of 3.7 months and femoral shaft fractures healed within an average of 4.8 months. Complications included one case of avascular necrosis of the femoral head, a varus healing of one femoral neck fracture, and a rotational malalignment of the femoral shaft in another case. There were no cases of hardware failure. The Russell-Taylor reconstructive nail allows concomitant hip and shaft fractures to be fixed with a single implant.

Long proximal femoral nail in ipsilateral fractures proximal femur and shaft of femur

Background:

Ipsilateral fractures of the proximal femur and femoral shaft are extremely uncommon injuries which occur in young adults who sustain a high energy trauma. A variety of management modalities have been tried to treat this complex fracture pattern ranging from conservative approach to recently introduced reconstruction nails. All these approaches have their own difficulties. We studied the outcome of long proximal femoral nail (LPFN) in the management of concomitant ipsilateral fracture of the proximal femur and femoral shaft.

Materials and Methods:

We analysed the prospective data of 36 consecutive patients who had sustained a high energy trauma (30 closed fractures and 6 open shaft fractures) who had concomitant ipsilateral fractures of the femoral shaft associated with proximal femur fractures treated with LPFN between December 2005 and December 2011. The mean age was 39 years (range 28-64 years). Twenty nine males and seven females were enrolled for this study.

Results:

The patients were followed up at three, six, twelve, and eighteen months. The mean healing time for the neck fractures was 4.8 months and for the shaft fractures was 6.2 months. The greater trochanter was splintered and widened in two cases which eventually consolidated. Two patients had superficial infection, two patients had lateral migration of the screws with coxa vara which was due to severe osteoporosis detected during the followup. We had two cases of nonunion of shaft fracture and one case of nonunion of neck fracture. Two cases of avascular necrosis of femoral head were detected after 2 years of followup. No cases of implant failure were noted. Limb shortening of less than 2 cms was noted in four of our patients. The functional assessment system of Friedman and Wyman was used for evaluating the results. In our series 59.9% (n = 23) were rated as good, 30.6% (n = 11) as fair, and 5.5% (n = 2) as poor.

Conclusion:

Long PFN is a reliable option for concomitant ipsilateral diaphyseal and proximal femur fractures.
