钛合金网架髋臼重建术

Acetabular reconstruction with autograft and Ti-alloy mesh

目的观察自体植骨 ,钛合金网架重建内陷性髋臼的临床效果。方法1993年1月～1995年8月 ,25侧内陷性髋臼应用局部自体植骨 ,钛合金网架重建术。男11髋 ,女14髋 ,年龄45～76岁 ,平均69岁。术前诊断类风湿性关节炎11髋 ,骨关节炎8髋 ,股骨头缺血性坏死4髋 ,髋臼发育不良2髋。平均随访4.5年 (3～5年 )。结果25髋按Merled Aubigne标准评分,平均为10.2分 ,优良率88 % ,全部植骨获得骨性融合。无髋臼帽松动 ,髋臼内壁无一发生骨折或金属网架断裂。结论自体植骨同时用钛合金网架加固 ,能有效重建内陷性髋臼。

Objective To observe the clinical results of reconstruction with autograft and Ti-alloy mesh for acetabular protrusion. Methods Between January 1993 to August 1995, 25 protrusio acetabuli were reconstructed with autograft and Ti-alloy mesh. There were 11 males and 14 females. The patients were aged 45-76 years, with an average of 69 years. Of the 25 hips, 11 were rheumatoid arthritis, 8 were degenerative arthritis, 4 were femoral head necrosis and 2 dysplasia. The average follow up was 4.5 years (range,3-5 years ).Results The average Merle dAubigne Score of 25 hips was 10.2. 88%of the patients was graded excellent and good results. All grafts achieved bony union. No acetabular component had definitely loosening. Acetabular inner wall fracture or broken mesh was not seen in any hip. Conclusion Autograft and Ti-alloy mesh could rebuild protrusio acetabuli effectively.
