全陶界面与金属-聚乙烯界面在人工全髋关节置换术后的早期临床效果比较

Comparison of postoperative early efficacy between ceramic-ceramics interface and metal-polyethylene interface in treatment of patients with total hip arthroplasty

目的比较全陶界面(COC)与金属-聚乙烯界面(MOP)在全髋关节置换术的临床早期疗效。方法对行第4代Delta全陶界面全髋关节置换术的28例患者(观察组)和金属-聚乙烯界面全髋置换术的32例患者(对照组)进行早期随访,所有患者均采用Harris评分系统评估髋关节功能,观察2组术后并发症发生情况。结果观察组术前及末次随访髋关节Harris评分、关节总活动度与对照组比较无显著差异(P> 0. 05)。所有患者均未出现假体松动、脱位、骨溶解以及假体周围骨折,5例患者(观察组2例,对照组3例)出现轻微疼痛,3例患者(观察组1例,对照组2例)出现异响,其中2例患者最后一次随访已消失,1例患者(观察组)仍有异响。结论全陶界面与金属-聚乙烯界面应用于全髋关节置换术的早期效果满意,二者均能有效减少因关节面磨损导致的关节松动、脱位等并发症。

Objective To compare the early efficacy of ceramic-ceramics interface （COC） and metal-polyethylene interface （MOP） in treatment of patients with total hiparthroplasty. Methods Totally 28 patients with the fourth generation Delta COC for total hip arthroplasty were selected as observation group, and 32 patients with MOP for total hip arthroplasty were selected as control group. All the patients were followed up, and hip joint function was assessed by Harris scoring system. The postoperative complications of the two groups were observed as well. Results There were no significant differences in Harris score of hip joint function and total joint activity before operation and at last follow up between the two groups （ P 〉0.05）. No patients had prosthesis loosening, dislocation, osteolysis and periprosthetic fracture. Only 5 patients （2 cases in observation group, 3 cases in control group） had slight pain, 3 patients （1 case in observation group, 2 cases in control group） had abnormal sound, of which 2 patients′syndromes disappeared in the last follow-up, 1 patient （observation group） still had abnormal sound. Conclusion Both COC and MOP can achieve satisfactory early efficacy in the treatment of patients with total hip arthroplasty, which can effectively reduce the incidence of complications such as joint loosening and dislocation caused by wear of articular surface.
