Patients with peri-acetabular osteolysis around a well fixed cementless acetabular component may be treated with liner exchange. When the locking mechanism is unreliable or unavailable, cementing the liner into the fixed acetabular component is a feasible option. The purpose of this study was to evaluate the clinical and radiographic long term results of this technique. Forty hip revisions with liner cementation in 37 patients were performed. The minimum follow up was 10 years. Modified Harris Hip Score and recent x rays were reviewed. Four hips were re-revised. Two patients were diagnosed with exacerbation of osteolysis but refused revision. Dislocation rate was relatively high (16%). Liner cementation technique in revision hip surgery is useful in patients with a well fixed metal backed acetabular component.
对于髋臼周围骨溶解且髋臼杯假体固定良好的非骨水泥型患者，可采用内衬置换治疗。当锁定机制不可靠或无法使用时，将内衬粘结到固定的髋臼部件中是一种可行的选择。本研究的目的是评估该技术的临床和影像学长期结果。对37例患者进行了40次内衬粘结的髋关节翻修手术。最短随访时间为10年。回顾了改良Harris髋关节评分和近期X线片。4例髋关节再次翻修。2例患者被诊断为骨溶解加重，但拒绝翻修。脱位率相对较高（16%）。内衬粘结技术在髋关节翻修手术中对金属背衬髋臼部件固定良好的患者有用。
