Methods： We performed 127 total arthroplasty operations between June 1999 to February 2003 and investigated 49 cementless hip replacements with the Metalcancellous cementless Lubeck Ⅱ system being used in all hips. There were twenty men and twenty-nine women whose mean age at the time of the operation was 60 years （range, 52-81 years）. The patients were divided into osteoporosis or normal groups according to the femoral metaphyseal BMD measured preoperatively. The average duration of follow-up was 30 months （range, 8-52 months）. We evaluated all of the patients from a clinical standpoint with use of a standard-terminology questionnaire with respect to the short-term curative effects and patients＇ satisfaction. Hip pain status and functional ability were important indicators of treatment efficacy. Results： Harris hip score and patients＇ satisfaction in femoral osteoporosis patients who underwent noncemented hip arthroplasty were lower （P=0.004, P=0.03） while the incidence of thigh pain was higher （P=0.03） than the patients with non-osteoporosis. Conclusion： The higher incidence of pain, as well as the decrease in function experienced by the patients in osteoporosis group, supports the case that cementless arthroplasty is not a better choice for those patients and that we had better select prosthesis based on the femoral metaphyseal BMD.展开更多
目的 探讨绝经女性患者骨密度(bone mineral density,BMD)对骨关节炎全膝关节置换术恢复情况的预测价值。方法 选取2019年4月至2021年12月湖州市第一人民医院收治的骨关节炎全膝关节置换术患者78例为研究对象,采用双能X线测量患者的BMD...目的 探讨绝经女性患者骨密度(bone mineral density,BMD)对骨关节炎全膝关节置换术恢复情况的预测价值。方法 选取2019年4月至2021年12月湖州市第一人民医院收治的骨关节炎全膝关节置换术患者78例为研究对象,采用双能X线测量患者的BMD水平,术后6个月采用美国膝关节协会评分(Keen Society score,KSS)对膝关节功能进行评估,根据KSS评分将患者分为恢复良好组(n=41)和恢复不良组(n=37);采用Logistic回归分析对患者术后膝关节功能恢复的影响因素进行评估;利用R软件建立预测列线图模型;绘制受试者操作特征曲线分析构建模型的预测效能。结果 术后6个月,非骨质疏松患者的KSS评分均显著高于骨质疏松患者(P<0.05)。两组患者的年龄、病程、绝经时间、BMD及体质量指数(body mass index,BMI)比较差异均有统计学意义(P<0.05)。多因素Logistic回归分析表明,年龄、BMI、病程、绝经时间及BMD均是影响骨关节炎全膝关节置换术后关节功能恢复的独立危险因素(P<0.05)。列线图构建关节功能恢复预测模型的曲线下面积为0.832 (95%CI:0.762~0.883),预测的敏感度与特异性较高。结论 绝经女性患者BMD对骨关节炎全膝关节置换术后关节功能恢复产生影响,建立的列线图对判断预后具有较高应用价值。展开更多
