Developmental dysplasia of the hip (DDH) is a major cause of hip arthritis and ultimately total hip arthroplasty. Due to the dysplastic acetabulum, how to place the acetabular cup becomes a challenge in acetabular reconstruction for such patients. Especially in the acetabula classified as Crowe typeⅡand type Ⅲ, the dislocation of the femoral head causes bone defects above the true acetabulum, which will affect the stability of the acetabular cup when the acetabular reconstruction is performed at the true acetabulum. Many acetabular reconstruction methods such as bone grafting, the use of small acetabular cups, socket medialization technique, and high hip center technique are used to increase the host bone coverage of the cup. However, each method has its own shortcomings that can not be ignored so that there is no unified conclusion on the acetabular reconstruction methods for Crowe typeⅡand type Ⅲ hip dysplasia. This article summarized and evaluated various reconstruction methods in combination with the acetabular morphology of DDH, and put forward the research direction in the future.
发育性髋关节发育不良（DDH）是髋关节炎以及最终全髋关节置换术的主要原因。由于髋臼发育不良，对于此类患者，在髋臼重建中如何放置髋臼杯成为一项挑战。特别是在CroweⅡ型和Ⅲ型髋臼中，股骨头脱位会导致真髋臼上方出现骨缺损，当在真髋臼进行髋臼重建时，这将影响髋臼杯的稳定性。许多髋臼重建方法，如植骨、使用小髋臼杯、髋臼内移技术和高髋臼中心技术等，都被用于增加髋臼杯的宿主骨覆盖。然而，每种方法都有其不可忽视的缺点，以至于对于CroweⅡ型和Ⅲ型髋关节发育不良的髋臼重建方法尚无统一结论。本文结合DDH的髋臼形态，对各种重建方法进行了总结和评估，并提出了未来的研究方向。
