摘要
目的 :研究髋臼缺损时全髋置换术髋臼重建的手术方法。 方法 :因先天性髋关节发育不良、全髋关节置换术失败等原因导致髋臼缺损的 118例 ( 12 5个髋 )行全髋置换术或翻修术 ,应用非骨水泥髋臼 ,并采用加深髋臼、上移髋臼、大型髋臼填充或结构植骨等方法。 118例中的 10 2例 (男 3 7例、女 65例 )得到随访 12个月至 10年 ,平均 62个月 ,另 16例失随访。结果 :根据 Merle D′Aubigne评分方法 ,优 2 2例 ,良 48例 ,中 3 1例 ,差 1例。结论 :各种髋臼骨缺损应根据 X线片及 CT加以明确 ,观察其运动中心、上移程度 ,结果对髋臼重建方法的选择特别有意义。非骨水泥髋臼重建成功与否有赖于假体稳定 ,并尽量与宿主骨接触 。
Objective: To study the surgical technique of reconstructure acetabulum for deficient acetabulum in total hip arthroplasty(THA). Methods: One hundred and twenty five hips of 118 patients with insufficient bone stock of acetabulum,such as CDH, failure of THA, underwent primary THA or revision. Variable technique reconstruction of the acetabulum by cementless acetabular component including deepening the medial wall of acetabulum,using a small cup or jumbo cup filling the expanded acetabulum, placing the component high position and structural bone graft were used. One hundred and two of 118 cases were reviewed. The mean follow up period was 62 months (12 months to 10 years). Results: Based on Merle D′ Aubigne evaluation method, all but one patients showed marked impovement.Conclusion: It is important for reconstruction of acetabular deffects to determine the extent of acetabular deficiencies by radiographic approch and CT. Measuring the hip center migration can help to determine the appropriate reconstruction method for each type of defect. However, good results with cementless acetabular component depend on the intial component stability, great contact with host bone and avoiding or decreasing structure bone graft.
