Osteosynthesis of ununited femoral neck fracture by internal fixation combined with iliac crest bone chips and muscle pedicle bone grafting

Background:Ununited femoral neck fracture is seen commonly in developing countries due to delayed presentation or failure of primary internal fixation. Such fractures, commonly present with partial or total absorption of femoral neck, osteonecrosis of femoral head in 8–30% cases with upward migration of trochanter posing problem for osteosynthesis, especially in younger individuals. Several techniques for treatment of such conditions are described like osteotomies or nonvascularied cortical or cancellous bone grafting provided varying degrees of success in terms of fracture union but unsatisfactory long term results occurred due to varying incidence of avascular necrosis (AVN) of femoral head. Moreover, in presence of AVN of femoral head neither free fibular graft nor cancellous bone graft is satisfactory. The vascularied bone grafting by deep circumflex iliac artery based on iliac crest bone grafting, free vascularied fibular grafting and muscle pedicle periosteal grafting showed high incidence of success rate. Osteosynthesis is the preferred treatment of choice in ununited femoral neck fracture in younger individuals.Results:The mean followup is 12.5 years (range 3-35). The union of fractures occurred in 202 (82.8%), delayed union in 18 (7.3%), and established nonunion in 24 (9.8%) patients. Full weight bearing was permitted at 16–22 weeks after union of fractures. Mean Harris hip score at the longest followup was 85.5. Among the complications, superficial wound infection occurred in 20 (8.2%), deep infection in seven (2.9%), and coxa vara in 39 (16%) patients. Preoperative radiodensity of femoral head disappeared mostly after the union of fracture whereas fresh radiodensity of femoral head appeared in 20 (8%) patients; nine (45%) of them developed segmental collapse.Conclusion:Ununited femoral neck fractureis characterized by absorption of femoral neck, posterior cortical defect, smoothening and overriding of fracture surfaces with intervening fibrous tissues associated with or without AVN of femoral head. The above method of osteosynthesis rectified the above pathology and provided satisfactory results with union of fractures in 90.1% patients at long term followup.

Internal fixation and muscle pedicle bone grafting in femoral neck fractures

Background:

The treatment of displaced intracapsular femoral neck fracture is still an unsolved problem. Non-union and avascular necrosis are the two main complications of this fracture, especially if patient presents late. Muscle pedicle bone grafting has been advocated to provide additional blood supply. We present analysis of our 32 cases of displaced femoral neck fracture treated by internal fixation and quadratus femoris based muscle pedicle bone grafting.

Materials and Methods:

Open reduction and internal fixation with muscle pedicle grafting was done in 32 patients. The age of patients varied from 14-62 years (average age 45 years) with male to female ratio of 13:3. Twenty-nine fractures were more than three weeks old. All the cases were treated by Meyers'' procedure. The fracture was internally fixed after open reduction and then a muscle pedicle graft was applied. It was supplemented by cancellous bone graft in seven cases. Fixation was done by parallel cancellous lag screws (n = 19), crossed Garden''s screws (n = 7), parallel Asnis screws (n = 5) and Moore''s pin (n = 1).Quadratus femoris muscle pedicle graft was used in 32 cases. In the initial 12 cases the graft was fixed with circumferential proline sutures, but later, to provide a secure fixation, the graft was fixed with a cancellous screw (n = 20). Postoperative full weight bearing was deferred to an average of 10 weeks.

Results:

Union was achieved in 26/29 (89.65%) cases which could be followed for an average period of 3.4 years, (2-8.5 years) with good functional results and had the ability to squat and sit cross-legged. Results were based on hip rating system given by Salvatti and Wilson. The results were excellent in 15 cases, good in four cases, fair in four cases and poor in six cases. Complications were avascular necrosis (n = 2), transient foot drop (n = 2), coxa-vara (n = 1) and temporary loss of scrotal sensation (n = 1).

Conclusion:

Muscle pedicle bone grafting with internal fixation is a viable treatment option in displaced femoral neck fractures with late presentation.     

Closed reduction, internal fixation with quadratus femoris muscle pedicle bone grafting in displaced femoral neck fracture

Background:

Management of femoral neck fracture is still considered as an unsolved problem. It is more evident in displaced fractures where this fracture is considered as some sort of vascular insult to the head of the femur. We have used closed reduction, internal fixation and quadratus femoris muscle pedicle bone grafting in fresh displaced femoral neck fractures.

Materials and Methods:

From April 1996 to December 2004 we operated 73 consecutive patients of displaced femoral neck fracture in the age group of 24 to 81 years, mean age being 54.6 years. The patients were operated within one week of injury, the mean delay being 3.6 days. Closed reduction internal fixation along with quadratus femoris muscle pedicle bone grafting was done in all cases. They were followed up for an average period of 5.6 years (range 2-11 years).

Results:

Results were assessed according to modified Harris Hip Scoring system and found to be excellent in 53, good in 12, fair in six and poor in two patients. Bony union occurred in 68 cases, no patient developed avascular necrosis (AVN) till date.

Conclusion:

For fresh displaced femoral neck fracture in physiologically active patients closed reduction, internal fixation and quadratus femoris muscle pedicle bone grafting is a suitable option to secure union and prevent development of AVN.

Augmented osteosynthesis with tensor fascia latae muscle pedicle bone grafting in neglected femoral neck fracture

Background:

Neglected intracapsular femoral neck fracture in young patients may fail to unite because of the excessive shearing strain at the fracture site and it is a surgical challenge to any orthopedic surgeon. The problem is compounded by resorption of the femoral neck and avascular necrosis (AVN) of femoral head. There is no satisfactory solution available in the management of femoral neck fracture as far as the union of the fracture and AVN of femoral head are concerned. Muscle pedicle bone grafting has been advocated to provide additional blood supply to the femoral head. We report a retrospective analysis of 48 cases of neglected femoral neck fracture treated by internal fixation and tensor fascia latae based muscle pedicle bone grafting.

Materials and Methods:

48 patients with femoral neck fractures with age varied from 20 to 53 years (average age 32.9 years) with male to female ratio of 2:1 were enrolled. All fractures were more than 3 weeks old with mean delay being 86 days (22–150 days). Open reduction and internal fixation along with tensor fascia latae muscle pedicle bone grafting was done in all cases. It was supplemented by multiple drilling and cortico-cancellous bone grafting. Fracture fixation was done with three parallel 6.5-mm AO cannulated cancellous lag screws and the graft fixed with a 4-mm cancellous screw to provide a secure fixation. During the followup period of 2-6.8 years (average 4.4 years) the results were assessed clinically by modified Harris hip scoring system and radiologically by the evidence of signs of fracture union.

Results:

Union was achieved in 41/48 (85.41%) cases which were followed for an average period of 4.4 years (2–6.8 years) with good functional results and ability to squat and sit cross-legged. Results were assessed according to modified Harris Hip Scoring system and found to be excellent in 19, good in 22, fair in 5, and poor in 2 patients. Complications were nonunion, (n=3) avascular necrosis (n=2), and coxa vara deformity (n=2).

Conclusion:

Internal fixation with muscle pedicle bone grafting is a suitable option to secure union in neglected femoral neck fractures in physiologically active patients with late presentation.
