Distal Femur Fractures: Contemporary Treatment Options and Surgical Strategies

Distal femur fractures represent complex injuries associated with significant morbidity, high complication rates, and challenging surgical management. These fractures occur across a broad patient spectrum, including high-energy trauma in younger individuals and fragility fractures in elderly patients with poor bone quality. In addition, periprosthetic fractures further complicate decision-making. A key concern is the elevated risk of non-union and suboptimal functional outcomes, making careful planning essential.

Management is guided by fundamental AO principles, including restoration of limb alignment, achieving stable fixation, preservation of blood supply, and early mobilization. Multiple surgical techniques are available, each with specific indications. Lateral locking plate fixation remains a widely used approach, offering angular stability and suitability for minimally invasive techniques. Retrograde intramedullary nailing provides a biologically favorable option, particularly for metaphyseal and diaphyseal extensions, while newer strategies such as nail–plate combination fixation and dual plating have emerged to address complex or unstable fracture patterns.

Optimizing outcomes requires attention to both mechanical and biological factors. Surgical technique plays a crucial role, including appropriate implant selection, plate length, screw density, and avoidance of excessive soft tissue disruption. Techniques such as percutaneous fixation and use of adjuncts like femoral distractors can improve alignment and facilitate reduction. Early mobilization and weight-bearing, when fixation stability allows, are important for recovery and may enhance healing. Despite advances, individualized treatment remains essential due to the variability in fracture patterns and patient factors.
