Complex femur fractures in children: treatment with external fixation.

External fixation was used to treat complex femur fractures in 10 children. These injuries were associated with head trauma, cerebral palsy, epidermolysis bullosa, open wounds, and failed casting. The duration of external fixation averaged 8 weeks, and the mean follow-up was 5 years 8 months. At follow-up, one patient had 2.6 cm of residual shortening, and two had overgrowth. Complications included one refracture. Three children developed superficial pin site drainage. Although most femur fractures can be treated with traction or casting, external fixation may simplify overall care in children with multiple injuries and is effective in controlling unacceptable femoral shortening and angulation.
