我院１９８８年以来采用自行设计的贯通式髋臼造盖术治疗ＣＤＨ３１例，通过临床实践，我们认为该手术方法比较简单可靠。手术方法为：股骨头复位后，于髋臼外缘凿一２５ｃｍ长方形骨槽，其深度贯通髂骨内板。骨槽方向为前下后上并与水平线成３０°角。从髂骨切取２ｃｍ×３ｃｍ×４ｃｍ梯形骨块，骨块凹面向下，短底边先插入骨槽内然后缓缓击入，直至骨块于髂骨内板穿出为止。用手摇晃嵌插的骨块不动为好。股骨头复位后紧缩缝合关节囊。本文介绍了手术设计思想，手术设计的生物力学合理性，手术要点。本组病例术前髋臼指数平均为３６°，术后为２１°，髋臼形态由斜坡状变为球窝状的变化率为７４％。股骨头覆盖率由术前１９％变为术后８６％，文章强调手术操作的准确性，并同时强调切取骨块要足够大，否则手术易失误
Our hospital since 1988 using self-designed through the acetabulum in the treatment of CDH31 cases, through clinical practice, we believe that the surgical method is relatively simple and reliable. Surgical methods: femoral head reset, in the outer edge of the acetabulum a 2 5cm rectangular slot, the depth of the ilium through the plate. The direction of the groove is before and after the next up and 30 ° angle with the horizontal line. From the ilium cut 2cm × 3cm × 4cm trapezoidal bone, concave face down, the short edge first inserted into the bone slot and then slowly into the bone until the iliac bone plate piercing so far. Swaying embedded in the bone motionless as well. Femoral head reduction after suture joint capsule. This article describes the surgical design ideas, surgical biomechanical rationality, surgical points. The average preoperative acetabular index in this group of patients was 36 ° after operation and 21 ° after operation. The change rate of acetabular shape from slope to ball-socket was 74%. The coverage of the femoral head changed from 19% preoperatively to 86% postoperatively. The article emphasizes the accuracy of surgical procedures and at the same time emphasizes that the cutting of the bone mass should be sufficiently large or the operation is erroneous
