J Surg Pak Jan ;18(1):28-31.

Objective: To determine the effectiveness of exchange nailing for delayed or nonunion of diaphyseal femur fractures. Study design: Descriptive case series. Place & Duration of study: Department of Orthopaedics Jinnah Postgraduate Medical Center Karachi, from March 2009 to February 2012. Methodology: All patients with delayed or hypertrophic nonunion of diaphyseal femur fractures diagnosed on clinical and radiological examination, were included. Patients with infective nonunion, segmental fractures or fractures with bone loss and open fractures were excluded. Exchange nailing was performed. Results: A total of 36 patients were managed which included 27 males and 9 females. Twenty-four (66%) patients were between 30 – 40 year of age. Left femur was predominantly involved (56%). The non union involved middle third in 61% cases. Following surgery union was achieved in 33 (92%) cases. In 14 patients union occurred between 4 to 6 months. Superficial infection occurred in 2 patients. Conclusion: Exchange nailing is the one of best options for delayed or nonunion of femoral diaphyseal fractures.
