摘要目的:探讨双动全髋关节假体在老年创伤性股骨颈骨折初次髋关节置换术中的应用效果。方法:回顾性收集2015年1月至2019年12月于晋城市人民医院成功接受初次髋关节置换术治疗的老年创伤性股骨颈骨折患者资料，年龄60～75岁。将髋关节置换术中行双动全髋关节假体手术的30例患者纳入观察组，将行骨水泥型人工半髋关节假体手术的30例患者纳入对照组。比较两组围术期相关指标、并发症、术后1～6个月髋关节功能恢复及日常生活能力评分。结果:观察组手术时间、术后部分负重时间、完全负重时间及住院时间少于对照组( t＝5.235、2.609、7.890、3.649， P＝0.001、0.012、0.001、0.001)。术前，两组关节功能力、日常生活能评分比较， P>0.05。术后1～6个月，两组关节功能力、日常生活能评分较术前升高( F＝285.155 、265.243， P<0.05)，且观察组分值高于对照组( F＝123.120、150.121， P<0.05)。两组并发症如术后感染、骨水泥反应综合征、下肢深静脉血栓、假体内脱位发生率比较，差异未见统计学意义(χ 2＝0.741、2.069、0.351、1.017， P>0.05)。 结论:老年创伤性股骨颈骨折患者行初次双动全髋关节假体置换术可缩短手术时间，术后可尽早下床活动，术后髋关节功能恢复较快，日常生活能力提高，且不增加术后并发症发生风险。

abstractsObjective:To investigate the effect of double-acting total hip prosthesis in the primary hip arthroplasty for elderly traumatic femoral neck fracture.Methods:The clinical data of elderly patients with traumatic femoral neck fracture who successfully received initial hip replacement in Jincheng People’s Hospital from January 2015 to December 2019 were retrospectively collected, aged 60-75 years. Among them, 30 patients who underwent double-action total hip prosthesis surgery in hip arthroplasty surgery were included in the observation group, and 30 patients who underwent cemented artificial hip prosthesis surgery were included in the control group. The perioperative indicators, complications, hip function recovery and daily living ability scores from 1 to 6 months after surgery were compared between the two groups.Results:The operation time, postoperative partial weight-bearing time, complete weight-bearing time and hospital stay in the observation group were less than those in the control group ( t=5.235, 2.609, 7.890, 3.649, P=0.001, 0.012, 0.001, 0.001). Before operation, the scores of joint function and daily life performance in the two groups were compared, P>0.05. At 1 to 6 months after operation, the scores of joint function and daily living ability in the two groups were higher than those before operation ( F=285.155, 265.243, P<0.05), and the scores in observation group were higher than those in the control group ( F=123.120, 150.121, P<0.05). There were no significant differences in the incidence of complications between the two groups, such as postoperative infection, cement response syndrome, deep vein thrombosis of the lower limbs, and dislocation of the prosthesis (χ 2=0.741, 2.069, 0.351, 1.017, P>0.05). Conclusions:The initial double-action total hip prosthesis replacement in elderly patients with traumatic femoral neck fracture can shorten the operation time. Patients can get out of bed as soon as possible after surgery, and their hip function will recover faster after surgery, their life ability will be improved, without increasing the risk of postoperative complications.
