摘要：Two groups of patients are mainly involved in subtrochanteric fractures:young patients with high-energy injury and elder patients with low-energy injury. Recently, bisphosphonate-induced atypical subtrochanteric fractures have attracted great attention as well. Due to the muscle strength surrounding the fracture site, the proximal femur has peculiar deformity of flexion, external rotation, abduction and adduction. Subtrochanteric region bears extremely high stress and is mainly constituted of cortical bone. All factors might contribute to the high rate of complications such as implant failure, nonunion and osteonecrosis of the femoral head, which make subtrochanteric fractures one of the most challenging types for orthopedic surgeons. Surgical management enjoys priority when the patient has no absolute contraindications. However, it is still of great controversy regarding the choice of implants. Intramedullary ifxation has deifnitely advantages over extramedullary ifxation on biomechanics for its short moment arm. With the development of biological reduction and ifxation, some minimally invasive extramedullary ifxations, including proximal femoral locking compression plate ( PF-LCP ) and less invasive stable system ( LISS ), have shown satisfactory clinical results. A number of factors might affect the treatment effects, including age, fracture pattern, reduction methods and quality as well as the fashion of internal ifxation.
