Outcome Analysis of Dual Implant Osteosynthesis for Ipsilateral Proximal and Shaft Femur Fractures: Do We Need Cephalomedullary Nails?

Introduction Most surgeons prefer a single implant for segmental proximal and diaphyseal femur fractures, although results are controversial and still no consensus for proper management is present. This prospective study analyses the functional and radiological outcome of managing 17 patients with ipsilateral shaft and proximal femur fractures by dual implant osteosynthesis at our center. Methods Over a two-year period, we managed 17 patients with a mean age of 35 years, with cancellous cannulated screws or dynamic hip screws for intracapsular femur fractures and improvised proximal femoral nail for extracapsular proximal femur fractures. Distal femoral locking plates or distal femoral nails were used for shaft femur fractures depending upon fracture morphology. The patients had a maximum follow-up of 18 months. Results A total of 80% of patients had a good functional outcome (using the Friedman-Wyman scoring system) while 60% had an excellent Harris Hip Score. The mean time taken for the bone union for proximal femur fractures was 4.75 months and for shaft femur fractures, it was 6 months. Conclusion We had a satisfactory functional and clinical outcome of managing these fractures with two implants, one focusing biomechanically on each fracture. This principle of dual implant osteosynthesis can reliably be used in such difficult fracture patterns and it negates the use of the single cephalomedullary nail for fixating both fractures.
