Abstract：
The creation of a single-bone-forearm is a salvage procedure to stabilize the forearm. The purpose of this study was to investigate clinical outcomes and how these patients compensate for the lack of forearm rotation. We evaluated four patients (three children, one adult) who had undergone single-bone-forearm surgery. Patients were examined clinically and with three-dimensional motion analysis. We found these patients are generally capable to perform important activities of daily living (e.g. glass jug pouring), which would normally need forearm rotation. Motion analysis revealed remarkable compensatory motion at other joints during these activities. We conclude that patients with a single-bone-forearm can maintain a certain level of daily activities by using compensatory motions at other joints, although the time needed to complete the tasks may be longer. Level of evidence: IV.
摘要：
单骨前臂的创建是稳定前臂的抢救程序。这项研究的目的是调查临床结果以及这些患者如何补偿前臂旋转的不足。我们评估了四名患者(三名儿童，一名成年人）接受过单骨前臂手术。对患者进行了临床检查和三维运动分析。我们发现这些患者通常能够进行重要的日常生活活动（例如玻璃罐浇注），这通常需要前臂旋转。运动分析显示，在这些活动中，其他关节的补偿性运动显着。我们得出的结论是，患有单骨前臂的患者可以通过在其他关节处使用代偿运动来维持一定水平的日常活动，尽管完成任务所需的时间可能更长。证据级别：IV。
