Vascularized iliac bone graft for displaced femoral neck fractures in young adults.
From November 1989 to September 1994, a total of 26 patients (18 men and 8 women) with acute displaced femoral neck fractures were treated with closed reduction and Knowles pinning combined with vascularized iliac bone grafting. Mean patient age was 37.5 years (range: 24-48 years). The mean time interval from injury to surgery was 3.6 days (range: 1-10 days). One patient experienced loss of the reduction at 6 weeks postoperatively and subsequently went on to hip replacement. Mean follow-up for the remaining 25 patients was 56.2 months (range: 20-78 months). All fractures united within 4 months. The average union time was 3.3 months. Plain radiographs confirmed the presence of avascular necrosis in 2 patients during the final follow-up; 1 of these patients developed systemic lupus erythematous 1 year after the fracture and had been treated with high doses of corticosteroid. Functional and radiographic results were satisfactory in the remaining patients.
