金属对金属全髋关节表面置换术早中期临床报告

目的探讨金属对金属全髋关节表面置换术治疗髋关节疾病的早中期临床效果,分析影响疗效的相关因素。方法回顾性分析我科全髋关节表面置换术患者54例60髋,男28例32髋,女26例28髋,年龄22～62岁,平均（42.3±12.5）岁。术后患者均进行定期临床与影像学随访16～45个月,平均随访32个月。采用Harris,UCLA,VAS评分对患者术前术后的髋关节功能进行评估。结果 Harris评分由术前38.3分增加到术后95.4分;UCLA评分由术前3.6分增加到术后7.9分;VAS评分由术前8.8分降低到术后1.8分。患者假体位置良好,无假体松动、关节脱位、股骨颈骨折及明显骨溶解等并发症。结论全髋关节表面置换术能有效改善髋关节疾病患者的关节功能、减轻疼痛,早中期随访结果满意。

Short and medium term clinical follow-up of metalon-metal hip resurfacing arthroplasty

Objective To evaluate the Short and medium term outcome of patients receiving metal-on-mental hip resurfacing arthroplasty and analyze the factors affecting the results.Methods 54 patients received metal-on-metal hip resurfacing arthroplasty were followed up for 16 to 45（average 32） months.Preoperative and postoperative pelvis plain radiographs were taken,Hip joint function was accessed before and after operation according to Harris,UCLA and VAS score. Results Harris and UCLA Score revealed an improvement from an average score of 38.3 and 3.6 preoperatively to 95.4 and 7.9 after the surgery respectively;VAS Score decreased from an average score of 8.8 to 1.8 after the surgery.No obvious complications such as prosthesis loosening,dislocation,femoral neck fracture and and bone absorption were found. Conclusion Metal-on-Metal hip resurfacing arthroplasty is effective at pain relief and joint function improvement and the Short and medium term outcome is encouraging.
