股骨假体周围骨密度变化对人工髋关节置换近期疗效影响的研究

目的探讨股骨假体周围骨密度对人工全髋关节置换术后近期疗效的影响。方法78名人工全髋关节术后的患者进行平均14个月的随访，随访时进行Harris评分，每个患者在术后1周和复查时都进行骨密度检查。结果在骨水泥固定组、非骨水泥固定组和杂交固定组，Harris评分低于80分的患者，其假体周围骨密度低于高于80分者。结论股骨假体周围骨密度能够反映假体周围骨丢失情况，股骨假体周围骨密度可能与人工髋关节置换术后的早期功能恢复有一定的关系。

Short-term effect of the periprosthetic BMD variations of femurs on hip replacement

Objective To study the short-term clinical influence of periprosthetic bone mineral density(BMD) variations on hip replacement.Methods Seventy-eight patients underwent hip replacement were followed up for an average of 14 months. Periprosthetic BMD and Harris scores were performed for all subjects at one week after operation and at each following-up.Results The periprosthetic BMD of patients with Harris scores <80 was lower than those with Harris scores >80 in all the three groups.Conclusions Periprosthetic BMD could show periprosthetic osteolysis and periprosthetic BMD may be associated with the Harris scores of hip.
