肩关节典型运动分析

Analysis on Typical Motion of Shoulder Joint

肩关节置换术是治疗肩关节疾病最有效的方法之一。术后短期内人工肩关节存活率高,患者恢复效果好,但长期而言,人工肩关节磨损产生的无菌性松动会大大增加手术失败的机率。肩关节结构复杂、典型运动不明确,目前国际上仍未公布人工肩关节的磨损试验标准。因此,需要研究、分析总结出肩关节的生物力学环境并建立相应的运动曲线,为人工肩关节磨损试验方案及标准的制定提供依据。本文基于人体肩关节活动规律,采用日常活动(activities of daily living,ADL)量表将肩关节活动能力划分为基本或躯体日常生活活动能力(basic or physical activities of daily living,BADL or PADL)和工具性日常生活活动能力(instrumental activities of daily living,IADL),并对其中几种特定运动规律建立了肩关节运动曲线。本文研究结果为人工肩关节磨损试验方案及标准的制定奠定了基础。

Shoulder arthroplasty surgery is one of the most effective method for treating shoulder joint diseases.In short term,the survival rate of the artificial shoulder joint is high,and the recovery effect of the patient is good,but in long term,the aseptic loosening caused by the wear and tear of the artificial shoulder joint will greatly increase the chance of surgical failure.Due to the complex structure and unclear typical motion of the shoulder joint,the wear test standards for artificial shoulder joints have not yet been published internationally.Therefore,it is necessary to study,analyze and summarize the biomechanical environment of the shoulder joint and establish corresponding motion curves,so as to provide references for the development of artificial shoulder joint wear test scheme and standards.Based on human shoulder joint activity rules,the shoulder joint activity ability can be divided into basic or physical activity of daily living(BADL or PADL) and instrumental activity of daily living(IADL) by using the activities of daily living(ADL) scale.In this study,shoulder joint motion curves for several specific motion rules were established.The results lay foundation for the establishment of wear test scheme and standard of artificial shoulder joint.
