人工腕关节假体研究进展

Research progress of artificial wrist joint prosthesis

目的总结人工腕关节假体的研究进展。方法查阅国内外人工腕关节假体相关研究,并进行总结分析。结果人工腕关节假体目前已发展至第4代,临床应用于治疗腕关节疾病,可有效缓解疼痛、改善功能,但仍然存在假体松动、下沉、断裂、脱位等问题。而且第3、4代假体仍缺少中远期随访结果。结论由于腕关节生物力学复杂,人工腕关节假体临床应用较少,置换术后早期疗效较满意,但仍然存在远期并发症,有待进一步研究发展。

Objective To summarize the research progress of the artificial wrist joint prosthesis. Methods Domestic and abroad literature concerning artificial wrist joint prosthesis was reviewed and analyzed thoroughly. Results Artificial wrist joint prosthesis has been developed to the 4th generation. The artificial wrist joint arthroplasty has advantages of pain relief and functional improvement and can achieve ideal short-term effectiveness. But there are some problems, such as loosening, subsidence, fracture, and dislocation of prosthesis. The long-term effectiveness of the 3rd and 4th generation prosthesis still need to be followed up. Conclusion The biomechanics of wrist joint is extremely complicated, which results in less application and slow development of artificial wrist joint prosthesis. Early-term effectiveness of artificial wrist joint arthroplasty is basically satisfactory, but there are still some long-term complications. So the artificial wrist joint prosthesis remains to be developed.
