This systematic review pooled 47 studies (N=1670) comparing operative fixation techniques for acute distal femur fractures published between 1989 and 2005. It evaluated compression plating, antegrade nailing, retrograde IMN, LISS, and external fixation across nonunion, fixation failure, infection, and reoperation rates. The goal was to identify the best fixation strategy and quantify the impact of surgical experience on outcomes.
In 2006, there was no consensus on which implant best fixed the metaphyseal-diaphyseal component of distal femur fractures, and the literature was dominated by uncontrolled case series with vastly different fracture populations being compared head-to-head.
This review establishes the benchmark complication rates every trainee should know: 6% nonunion, 3.3% fixation failure, and 16.8% reoperation across all techniques. When a patient asks about risks, these are your numbers.
Because no implant proved superior, your choice of compression plate vs LISS vs retrograde nail should be driven by fracture pattern, bone quality, and what your attending does well — not by evidence favoring one device.
The surgeon volume finding is the most actionable result: higher-volume surgeons cut reoperation nearly in half. Seek mentorship at high-volume trauma centers and recognize that technical execution outweighs implant selection in this injury.
