新型髋关节假体行全髋关节置换术后近期疗效分析

The analysis of the short-term outcome of the novel hip prosthesis total hip replacement

目的通过前瞻性研究,对比分析国产髋关节假体与国际品牌髋关节产品的全髋关节置换术后近期疗效。方法以我科自2009年3月至2010年4月由同一组手术医生进行的国产髋关节假体全髋关节置换26例患者(26髋)为研究对象,并与同期本手术组医生所进行的国际品牌的26例髋对比分析。实验组和对照组术前及术后均行Harris评分,实验组术前平均(37.6±4.32)分,对照组术前平均(38.7±4.16)分。所有患者进行平均17个月随访。结果对实验组和对照组分别统计术后1周、4周、3个月、半年Harris评分。实验组术后Harris平均分较术前明显提高(<0.05),两组间术后对比无统计学意义(>0.05)。实验组病例术后出现1例置换关节脱位,两组均无明显下肢深静脉血栓症状、感染、下肢不等长及坐骨神经损伤等并发症发生。结论实验组在近期疗效上能达到与对照组同样的满意效果。全髋关节置换术能够明显解除患侧关节疼痛、改善关节功能;对于股骨颈骨折患者能早期恢复活动;避免长期卧床所致的并发症;使患者术后明显提高生活质量。

Objective By prospective study, to analyze the short-term outcome of the total hip replacement of the tested hip joint prostheses, compared with an international brand of hip joint products. Method We researched 26 cases （26 hips） of the total hip replacement of the tested hip joint prostheses, treated by the same group surgeons from March 2009 to April 2010, compared with 26 hips of an international brand of hip joint products completed by our department during the same period. The experimental group and the control group were assessed by the preoperative and postoperative Harris scores, the average preoperative score of the experimental group was （37.6＋4.32）, and the control group was （38.7~4.16）. All the patients were followed up for 17 months. Result We counted the postoperative Harris of the experimental group and the control group respectively afer 1 week, 4 weeks, 3 months and half a year. The average postoperative Harris scores of the experimental group were improved obviously compared with the preoperative conditions （P 〈 0.05）, there was no postoperative statistical significance between the two groups （P 〉 0.05）. There was 1 ease replacement joint de- articulation in the experimental group after operation, no deep vein thrombus of lower limbe, infection, lower limbs length inequality, siatic nerve damage and other complications in both two groups. Conclusion The experimental group have the same satisfying effects of the short-term outcome, compared with the control group. Total hip replacement can remove with joint pain obviously, improve joint function; for femoral neck fracture patients can early recovery activities; avoid the complications caused by prolonged bed; and make patients improve the quality of life after operation distinctly.
