Nonunion of fractures of the femoral neck in children.

Overview

The authors present the prospective clinical outcome of nine pseudoarthroses resulting from surgical treatment carried out in nine children, whose ages varied from 6 years and 2 months to 14 years and 2 months (mean 10 years and 2 months), who had fractures of the femoral neck. Five were classified as type II, according to the Delbet classification modified by Colonna, and four were type III. The initial fractures were caused by high-energy traumas, such as trampling, bicycle falls, and car accidents. Treatment of choice was valgus osteotomy of the femoral neck associated or not with insertion of bony graft. The mean time of follow-up was 38 months, ranging from 23 to 71 months, and the mean time of pseudoarthrosis consolidation after osteotomy was 76.6 days, varying from 45 to 240 days. In this study, all the pseudoarthroses consolidated. For final analysis of clinical and radiographic results, the Ratliff's classification was used. We obtained three cases as good results, five as fair and one as poor. The authors concluded that valgus osteotomy is a good option for treatment of pseudoarthrosis in the femoral neck fractures in children.
