Closed intramedullary osteotomy for the correction of deformities of the femur.

Over the period 1986-1990, an intramedullary saw was used to correct length inequality, rotational and axial deformities and malunions of 17 femora in 15 patients. Interlocking intramedullary nails were inserted after the osteotomies were performed. No postoperative complications were encountered. Quadriceps function returned within 2-8 days and all osteotomies healed radiographically within 3 months. All deformities were satisfactorily corrected and all patients were pleased with the outcome. The intramedullary nails were removed in the majority one year following surgery. The authors conclude that closed intramedullary osteotomy of the femur is a safe and effective technique to correct deformities of the femur, although demanding in terms of experience and equipment.
