Ender rod fixation of femoral shaft fractures in children.

Ender rod fixation for femoral shaft fractures in children was evaluated in a prospective study at two Level 1 trauma centers. Fifty-seven fractures in 52 patients were evaluated. Criteria for inclusion in the study included age younger than 14 years, femoral shaft fractures occurring in the middle 3/5, canal size greater than 7 mm, and parental consent. Hip and knee motion, gait, leg length discrepancy, and rotational asymmetry were evaluated by clinical examination. Standard radiographs were used to measure any residual angulation. A subset of patients whose injuries occurred more than 12 months previously was evaluated using scanograms. Followup averaged 20 months. There were no delayed unions and all fractures healed within 12 weeks. Clinically significant leg length discrepancy, malunion, or loss of motion did not occur. Functional results were excellent and complications were minor. Ender rod fixation of femur fractures in children allows the advantages of surgical fixation with minimal risk of complications.
