Subtrochanteric fractures involve the proximal femur just below the lesser trochanter and are uniquely challenging due to the dense cortical bone and powerful muscle forces acting across the region, which produce predictable deformity patterns. These injuries typically result from high-energy trauma in younger individuals or low-energy falls in elderly patients with osteoporotic bone. A wide spectrum of fracture morphologies adds further complexity, necessitating individualized surgical planning. A sound understanding of the injury mechanism and fracture configuration is essential to formulate an effective reduction and fixation strategy. The difficulty in managing these fractures lies in the high physiological forces across the subtrochanteric region, frequent medial comminution, and the inherent instability caused by muscle pull. These factors contribute to reported malunion rates of 10% to 15% and nonunion rates that may reach up to 15% in some series. Reduction is often difficult with traction alone, as muscle forces exacerbate deformity. The wide and sometimes deformed proximal medullary canal limits the role of the nail as a reduction aid, often necessitating adjunctive reduction techniques such as Steinmann pin joysticks, provisional plating, or percutaneous clamps. Implant selection should be guided by fracture pattern, bone quality, and patient-specific considerations. Intramedullary nails are generally preferred for their biomechanical advantage, particularly in comminuted fractures, while extramedullary devices remain valuable in selected scenarios. Ultimately, careful preoperative planning and adherence to sound biomechanical principles are key to optimizing outcomes in this complex and technically demanding fracture pattern. This article provides a comprehensive overview of the anatomy, injury mechanisms, surgical challenges, and current strategies in the management of subtrochanteric femur fractures, with particular focus on reduction techniques and decision-making in implant selection to achieve durable fixation and early mobilization.
