When addressing subtrochanteric fractures, one of the most significant challenges is the nature of the fracture itself, which often involves extreme angular forces and a minimal bony interface. This anatomical region, located just below the greater trochanter of the femur, experiences significant mechanical stress during weight-bearing activities. As a result, fractures here are subjected to complex forces that can displace the fragments severely.

The minimal bony interface in subtrochanteric fractures refers to the small surface area available for stable fixation. This lack of adequate bone for solid anchoring can make it difficult to achieve stable fixation through conventional methods such as plates or intramedullary nails. The combination of these factors can result in poor mechanical stability after fixation, increasing the likelihood of malunion or nonunion if the functional forces acting on the site are not adequately countered.

Recognizing this complexity is essential for developing effective surgical strategies and rehabilitation protocols aimed at optimizing patient outcomes following such fractures. By understanding the specific challenges posed by the unique biomechanics of subtrochanteric fractures, clinicians can better tailor their approach in both surgical intervention and postoperative care.
