We conducted a retrospective study of the placement of porous-coated acetabular components using screws at more than 20 mm above the teardrop without structural bone graft for dysplastic hips to determine long-term outcome. Thirty hips (29 patients) were monitored for a mean of 15.2 years (range, 10.4-18.3 years) after surgery. Compared with 12 contralateral normal hips, the distance of the hip center from the teardrop was significantly high (26.8 +/- 4.8 and 13.4 +/- 2.7 mm P < .001); however, it was not laterally different (31. 5 +/- 5.1 and 31.7 +/- 5.0 mm). No acetabular components showed loosening. One metal shell was revised for wear and osteolysis. Morselized bone grafted in 25 hips was incorporated in all cases. Slight elevation of the hip center without lateralization in cementless cups fixed with screws was well tolerated for dysplastic hips.
我们进行了一项回顾性研究，针对发育不良性髋关节，在泪滴上方20多毫米处使用螺钉置入多孔涂层髋臼组件，且不进行结构性骨移植，以确定长期疗效。术后对30例髋关节（29例患者）进行了平均15.2年（范围为10.4 - 18.3年）的监测。与12例对侧正常髋关节相比，髋关节中心距泪滴的距离显著更高（分别为26.8±4.8和13.4±2.7毫米，P <.001）；然而，其在侧方并无差异（分别为31.5±5.1和31.7±5.0毫米）。没有髋臼组件出现松动。有1个金属杯因磨损和骨溶解而进行了翻修。25例髋关节中植入的碎骨均全部融合。对于发育不良性髋关节，用螺钉固定的非骨水泥杯使髋关节中心轻度抬高且无侧方移位，患者对此耐受性良好。
