背景:在全髋关节置换中,髋臼缺损很常见,为重建一个稳定、牢固的髋臼,置换过程中往往需要髋臼的重建.目的:探讨螺钉固定钛网结合骨水泥型髋臼杯在髋臼重建中应用的早期疗效.方法:纳入采用螺钉固定钛网结合骨水泥型臼杯重建髋臼髋关节翻修的患者23例.疼痛病史1-3年,术前 Harris 评分20-48分,平均34分.重建后采用 X 射线平片评价髋臼假体松动标准进行影像学评价及 Harris 评分定期随访.结果与结论:重建后随访1-3年,平均随访24个月,无脱失.重建后3个月 Harris 评分较重建前显著增高,置换后2年髋关节活动度较置换前显著增高,差异均有显著性意义(P <0.05).2例患者下肢不等长,1例患者下蹲后出现脱位,保守治疗后好转.最后一次随访时无早期感染、脱位,无盆腔不适感.重建后随访影像学上显示无髋臼假体松动与移位,未发生钛网断裂.说明螺钉固定钛网结合骨水泥型髋臼杯治疗65岁以上髋关节翻修患者其近期疗效十分满意,后期疗效还有待于进一步随访观察.

@@@@BACKGROUND: In total hip arthroplasty, acetabular defects are common, for the reconstruction of a stable and solid acetabulum, the acetabular reconstruction is often required during the replacement process.OBJECTIVE: To investigate the early effect of the short term results of titanium mesh fixed by screws combined with a cemented acetabular cup in acetabular reconstruction. METHODS: Twenty-three patients treated with acetabular reconstruction by screw fixed titanium mesh combined with a cemented acetabular cup were selected. The pain history was 1 to 3 years. Harris scores before operation were 20-48 with an average score of 34. X-ray plain film was used to evaluate theacetabular prosthesis loosening standards after reconstruction for the radiographic evaluation and Harris score of regular fol ow-up. RESULTS AND CONCLUSION: Al the patients were fol owed-up for 1-3 years and average in 24 months without losing. The Harris score at 3 months after operation was higher than that before operation, and the hip activity at 2 years after operation was higher than that before operation, and the difference was significant (P <0.05). Two patients stil had leg length discrepancy, one patient with dislocation after squatting, and recovered after conservative treatment. The last fol ow-up showed there were no early infection, dislocation and pelvic discomfort. Radiographic results showed that there was no aseptic loosening and displacement of the acetabular cap and there was no fracture on titanium mesh. Screw fixed titanium mesh combined with a cemented cup is satisfactory process in the treatment of hip revision in over 65 years old patients, and the long-term effects are needed to be further fol owed-up and observed.
