The treatment of the upper extremities is not as prevalent as that of the lower limbs, but it is nonetheless equally important. Today, there are no load data relating to upper extremity bone-anchored prosthesis users in the literature, but they are important in order to improve the rehabilitation protocol, design aspects and confidence of the user when it comes to loading the prosthesis in daily life. The aim of the present study was to investigate, in a population of eleven transhumeral amputees with osseointegrated implants, the load levels reached during specific prosthetic movements at maximum voluntary effort and during daily activities. The data showed a wide range of maximum load levels throughout the different activities. Furthermore, the data indicate that some test subjects felt apprehensive about loading the prosthesis, resulting in relatively low loads compared with the group as a whole. Within the limits of the present study, it was concluded that loading the implant system was subject specific, which resulted in large subject-to-subject variability. Moreover, some subjects exhibited uncertainty about the levels that could damage the fixation or the implant system. The study illustrates the diversity and uncertainty that exist in a population of transhumeral amputees treated with bone-anchored prostheses in terms of loading in daily life.
上肢的治疗不如下肢那么常见，但同样重要。目前，文献中没有涉及上肢骨锚式假体使用者的负荷数据，但这些数据对于改进康复方案、设计方面以及用户在日常生活中加载假体的信心非常重要。本研究的目的是在 11 名接受骨整合植入物的肱骨截肢患者中，调查在最大自主努力和日常活动中进行特定假体运动时达到的负荷水平。数据显示，在不同的活动中，最大负荷水平范围很广。此外，数据表明，一些测试对象对加载假体感到担忧，导致与整个组相比，负荷相对较低。在本研究的范围内，可以得出结论，加载植入物系统是特定于个体的，这导致了个体之间的很大变异性。此外，一些受试者对可能损坏固定装置或植入物系统的水平存在不确定性。该研究说明了在使用骨锚式假体治疗的肱骨截肢患者群体中，日常生活中的加载存在多样性和不确定性。
