The utility of reverse distal femur locking compression plate in minimally invasive osteosynthesis for type C subtrochanteric fractures of the femur: technical description and a clinical series of 50 cases.

BACKGROUND

Establishing fracture consolidation and avoiding postoperative complications of comminuted subtrochanteric fractures of the femur are technically challenging. The authors delineated a technical description of minimally invasive plate osteosynthesis (MIPO) by using a reverse distal femur locking compression plate (LCP-DF) and retrospectively reviewed the outcomes of these particular fractures.

METHODS

Fifty patients with 51 type C subtrochanteric fractures of the femur were operated on by MIPO and reverse LCP-DF fixation. The collected data included postoperative complications, union times, and clinical outcomes.

RESULTS

All fractures were united with a mean union time of 19.4 weeks (range 16-22). Regarding postoperative complications, asymptomatic valgus angulation occurred in five patients and trochanteric pain in six. According to Harris hip score, nine patients were determined to be excellent, 36 to be good and five to be fair.

CONCLUSION

MIPO by reverse LCP-DF is reliable and effective for type C subtrochanteric fractures of the femur particularly in situations where intramedullary nailing is not feasible.
