陶瓷对陶瓷全髋关节置换治疗中青年股骨颈骨折的分析

背景：陶瓷对陶瓷全髋关节置换适用于活动量较大、生活质量要求较高的年轻患者。目的：分析陶瓷对陶瓷全髋关节置换治疗青壮年患者股骨颈骨折近期治疗效果。方法：使用陶瓷对陶瓷全髋关节置换治疗的年龄在50岁以下的中青年股骨颈骨折患者51例，评估患者治疗后髋关节功能及并发症。结果与结论：所有患者均获随访，随访时间6个月至3年8个月。末次随访时，Harris 评分为（92.0±3.4）分，优良率94.1%。置换后无关节脱位病例发生，3例轻度跛行，均未作特殊处理。至随访结束影像学检查结果显示，未见假体松动、下沉及碎裂发生，假体周围无透亮线形成。陶瓷对陶瓷人工髋关节置换治疗活动量相对较大的青壮年患者股骨颈骨折能有效减少因磨损碎屑造成的骨溶解，减少假体的松动及下沉，延长关节的使用寿命，改善患者的生活质量。

Ceramic-on-ceramic total hip arthroplasty in young and middle-aged patients of femoral neck fracture

BACKGROUND：Ceramic-on-ceramic total hip arthroplasty can be applied to young patients requiring frequent activity and high quality of life. OBJECTIVE：To explore the short-term efficiency of ceramic-on-ceramic total hip arthroplasty in young and middle-aged patients of femoral neck fractures. METHODS：Fifty-one young and middle-aged patients under 50 years old with ceramic-on-ceramic total hip arthroplasty were selected to analyze the function of hip joints and the complication after operation. RESULTS AND CONCLUSION：Al the patients were fol owed up for 6 months to 44 months. At the last fol ow-up, the average Harris score was 92.0±3.4 points with an excellent and good rate of 94.1%. No dislocation was observed and three cases exhibited mild limping. Imaging examination showed that, no prosthesis loosing, broken, sinking or radiolucent line around prosthesis was observed. Ceramic-on-ceramic total hip arthroplasty in young patients with femoral neck fractures can effectively decrease the osteolysis, prosthesis loosing and sinking caused by the debris of wearing, prolong the working life of the prosthesis, and improve the patient’s quality of life.
