摘要
目的探讨全髋关节置换术治疗髋臼发育不良(DDH)伴髋关节骨性关节炎的手术疗效。方法对11例(12髋)因DDH致髋关节骨性关节炎患者行全髋关节置换术。根据Zionts分级,Ⅰ度7髋,Ⅱ度5髋。术前Harris评分28~63(48.1±9.4)分。结果11例均获随访,时间6个月~6年。术后Harris评分为82~98(88.6±7.6)分。1例术后3年X线片示人工臼与植骨块间有透亮线,余患者人工臼位置均无移位、松动。有2例患肢轻度跛行,无疼痛,可以长距离行走。结论全髋置换术解除患者症状,改善关节功能,提高生活质量,是一种行之有效的治疗方法。手术成功的关键在于加深髋臼、内移髋关节活动中心及适当植骨。
Objective To introduce the results of total hip arthroplasty in the treatment of developmental dysplasia of the hip (DDH) with osteoarthritis. Methods A total of 12 hips in 11 patients underwent total hip arthroplasty. According to the Zionts classification,7 hips belonged to type Ⅰ ,5 type Ⅱ. Harris scores before operation were 28 - 63 with an average scores of 48. 1± 9.4. Results All the patients were followed up for 6 months - 6 years. The Harris scores after operation were 82 - 98 with an average scores of 88. 6 ±7.6. All patients were pain-free, but 2 patients walked with slight limp after the operation. There was no sign of aseptic loosening and subsidence, except a zona pellucida between the implanted bone and the artificial acetabulum after 3 years of the operation in one case. Conclusions Total hip arthroplasty is an effective method for the treatment of osteoarthritis secondary to DDH. The key techniques for the total hip arthroplasty are as follows:deepening the medial wall of the acetabulum,improving the techniques of the bone graft,and firmly placing the acetabular component in the true acetabulum.
