Purpose. To evaluate the use of fibular grafting for fresh femoral neck fractures with posterior comminution. Methods. 18 women and 15 men aged 20 to 60 years underwent osteosynthesis and fibular strut grafting supplemented with 7.0-mm cannulated hip screws for Garden grades III (n=21) and IV (n=12) femoral neck fractures associated with posterior comminution. All fractures were reduced by closed methods, and no hip was aspirated. Clinical and radiological outcomes were evaluated. Results. The mean delay in presentation after injury was 3.2 (range, 1–12) days. The mean delay in operation was 8.8 (range, 5–21) days. The mean follow-up period was 2 (range, 1–4) years. According to the Harris hip score, outcome was good to excellent in 20 patients, fair in 7, and poor in 6. 27 of the 33 patients achieved bone union after a mean of 4.7 (range, 4.2–7) months. In 5 patients, the bone was united with a mean of 10° of varus collapse and a mean of 1 cm of shortening. Six patients had nonunion. Other complications included screw migration in the joint space (n=1), graft migration into the joint space (n=3), and screw pullout (n=5). No patient had avascular necrosis of the femoral head. Conclusion. Osteosynthesis and fibular grafting for freshly displaced femoral neck fractures with posterior comminution is an inexpensive and technically less demanding procedure for retaining a stable, painless, mobile, and functional hip.
