髋臼旋转截骨术（RAO）、基亚里截骨术和髋臼支架术是延缓发育性髋关节发育不良（DDH）患者骨关节炎进展的重要治疗方法，但其生物力学差异尚不清楚。本研究旨在探讨三种手术方式对髋关节生物力学的影响。在8具成人尸体标本上建立16个DDH模型，采用不同的手术方法进行处理，然后用应变片测量股骨头周围的应变。髋臼髋臼外固定术（P左= 0.016，P右= 0.021）和髋臼旋转截骨术（P = 0.004）治疗后，DDH模型髋关节应变值明显降低，而基亚里截骨术治疗后髋关节应变值无明显变化（P = 0.856）。RAO治疗组的改善率明显优于支架术（P = 0.015）和基亚里截骨术（P = 0.0007），支架术组的下降幅度大于基亚里截骨术（P = 0.018）。从生物力学角度看，RAO术在缓解髋关节应力方面优于支架术和基亚里截骨术。
Rotational acetabular osteotomy (RAO), Chiari osteotomy and shelf procedure are important treatments to delay the progression of osteoarthritis in developmental dysplasia of hip (DDH) patients, but their biomechanical differences are still unknown. This study was to evaluate the different biomechanical changes of hip joint after these three surgeries. Sixteen DDH models of 8 human cadaver specimens were reconstructed, and treated by different surgeries, and then strain around femoral head was evaluated by strain gauges. Hip strain value of DDH model was decreased after treated by shelf procedure (Pleft = 0.016 and Pright = 0.021) and rotational acetabular osteotomy (P = 0.004), but not in Chiari osteotomy (P = 0.856). Moreover, the improved ratio of RAO treatment was better than shelf procedure (P = 0.015) and Chiari osteotomy (P = 0.0007), and the descendent range of shelf procedure was greater than Chiari osteotomy (P = 0.018). From biomechanics points, RAO was more effective in relieving hip joint stress compared with shelf procedure and Chiari osteotomy.
