髋臼是典型的杵臼关节，其生理作用为连接躯干和下肢。髋臼是人体力学传导、维持正常活动的重要结构，其位置较深、周围结构复杂。髋臼骨折多由高能量损伤造成，发生骨折后对其做出迅速明确的分型诊断及相应处理成为许多创伤骨科医师面临的一大难题。目前，髋臼骨折分型方法复杂多样，许多传统分型方法存在难以理解、不能直观反映骨折形态、学习曲线较长和不能决定治疗、指示预后等不足。笔者重点对传统髋臼骨折分型方法进行梳理，对近二十年新提出的分型方法进行总结分析，并参阅相关文献客观阐述其优缺点，以期能加深创伤骨科医师对髋臼骨折的认识。“,”The acetabulum is a typical spheroid joint and its physiological function is to connect the trunk and lower limbs. As an important structure for human mechanical conduction and maintenance of normal activities, the acetabulum is anatomically deep with complicated peripheral structures. Acetabular fractures are generally caused by high energy trauma. After the fractures occur, it is a big problem for many orthopedic trauma surgeons to make a rapid and accurate diagnosis and treatment. At present, the classification methods of acetabular fractures are complex and diverse. Many traditional classification methods are difficult to understand and directly reflect the fracture morphology, have a long learning curve, camn't determine treatment or indicate prognosis. The authors aim at sorting out the traditional classification methods of acetabular fractures, summarizing and analyzing the classification methods newly proposed in the past two decades, and objectively describing their advantages and disadvantages by referring to relevant literatures, in order to deepen the understanding of acetabular fractures among orthopedic trauma surgeons.
