The aim of this study was to quantify the compensatory movements of the shoulder and elbow in patients with congenital radioulnar synostosis during 10 activities of daily living (ADL).
Maximum and minimum joint angles and range of motion were measured by use of a motion capture system in seven patients and seven matched controls. The forearm was fixed in 0 degrees of rotation in four patients and in 20 degrees of pronation in three patients.
The main compensatory movements were shoulder internal/external rotation during five ADL tasks, shoulder abduction/adduction and elbow flexion/extension during three tasks, and shoulder flexion/extension during two tasks. These compensatory movements were observed mainly when turning a key and drawing.
Patients with congenital radioulnar synostosis in nearly neutral rotation could perform all ADL tasks with the aid of compensatory movements of the shoulder and elbow.
本研究的目的是量化先天性桡尺骨融合患者在10项日常生活活动（ADL）中肩部和肘部的代偿运动。
使用运动捕捉系统测量7例患者和7例匹配对照的最大和最小关节角度及运动范围。4例患者的前臂固定在0度旋转位，3例患者的前臂固定在旋前20度位。
主要的代偿运动为5项ADL任务中的肩部内旋/外旋、3项任务中的肩部外展/内收和肘部屈伸，以及2项任务中的肩部屈伸。这些代偿运动主要在转动钥匙和画画时观察到。
近中立旋转位的先天性桡尺骨融合患者可借助肩部和肘部的代偿运动完成所有ADL任务。
