【 摘 要 】

Hip fractures are among the most common fractures in orthopaedics, and are associated with a high social burden and mortality, estimated at approximately 22% at one year.1 The worldwide incidence of hip fractures is estimated at 1.5 million people per year, rising to 2.6 million in 2025 and 6.25 million in 2050, because of the aging population and an increased incidence of osteoporosis.2 Hip fractures (proximal femoral fractures) are classified in accordance with the Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) classification into trochanteric (31A), femoral neck (31B) and femoral head (31C) fractures. Trochanteric fractures are defined as fractures occurring from the extracapsular basilar femoral neck to the region along the lesser trochanter, proximal to the medullary canal, and represent approximately 50% of proximal femoral fractures.3 Trochanteric fractures are further classified into simple pertrochanteric, two-part fractures (31A1), multi-fragmentary pertrochanteric fractures (31A2) and intertrochanteric fractures with a horizontal (reverse oblique) line (31A3) (Table 1).4 A stable fracture, once reduced and fixed is compressed and minimally displaced by weight-bearing. A1 and A2 fractures demonstrate generally stable patterns. Unstable fracture patterns include dorsomedial comminution, basicervical patterns, reverse obliquity patterns and fractures with an incompetent lateral wall and are associated with collapse on axial loading.
