摘 要 目的：探讨多孔钽金属涂层髋关节假体置换术在老年股骨颈骨折治疗中的应用价值。方法：选取80例老年股骨颈骨折患者作为研究对象。随机分为观察组与对照组各40例，对照组采用常规生物型髋关节假体治疗，观察组采用多孔钽金属涂层髋关节假体治疗，比较两组髋关节功能的恢复及手术一般指标。结果：两组手术用时、术中出血量、住院时间、术后开始负重时间差异无统计学意义（P>0.05）。观察组术后并发症发生率低于对照组；术后3、6个月Harris评分高于对照组（P<0.05）。结论：多孔钽金属涂层髋关节假体治疗老年股骨颈骨折可有效改善患者髋关节功能的恢复情况。

ABSTRACT Objective： To investigate the application value of porous tantalum coated hip arthroplasty in the treatment of elderly femoral neck fracture. Methods： Eighty cases of elderly patients with femoral neck fracture were selected as research subjects and were randomly divided into an observation group and a control group with 40 cases each. The control group was treated with conventional biological hip joint prosthesis and the observation group with porous tantalum coated hip joint prosthesis. The recovery of hip joint function and the general indexes of operation were compared between the two groups. Results： there were no significant differences in operation time， intraoperative blood loss， hospitalization time and postoperative weight-bearing time between the two groups （P>0.05）. However， the incidence of postoperative complications was significantly lower and Harris scores at 3 and 6 months after operation were significantly higher in the observation group than the control group （P<0.05）. Conclusion： Porous tantalum coated hip prosthesis can effectively improve the recovery of hip joint function in elderly patients with femoral neck fracture and the stability of its prosthesis is reliable and the incidence of complications is low and is suitable for elderly patients with relatively poor bone conditions.

股骨颈骨折是临床常见的下肢骨折类型之一，由于老年人群普遍机体素质状态较差且多合并有多种慢性病，如高血压、冠心病等，活动能力较差，因此当发生跌倒、交通意外等暴力因素时极易发生股骨颈骨折。目前，临床针对股骨颈骨折的治疗技术较为成熟，但受老年人群髋关节骨质条件的影响，传统保守疗法或内固定术的近远期预后均不理想，因此临床多采用全髋/半髋关节置换术治疗老年股骨颈骨折，可显著提升骨折愈合率，术后髋关节功能恢复良好[1-2]。但不同材料的髋关节假体在功能与预后方面存在较大的差异。
