Treatment of severe sternoclavicular joint dislocation by internal fixation 重度胸锁关节脱位的内固定治疗
2.
The sternoclavicular articulation is the only point at which the upper extremity is connected to the rest of the skeletal system 胸锁关节是上肢与骨骼系统的其它部分相连接的唯一部位。
3.
The aim is to get the rotation angles of left and right hands ' shoulder joints , elbow joints , wrist joints , sternoclavicular joint and the trunk when there is the longest horizontal distance between the center of gravity and the finish position 主要目的在于利用创建的模式求解重心与冲线位置生成最大水平距离时，左右手之肩关节、肘关节、腕关节及颈关节与躯干扭转的角度。
4.
The result and discussion show three conclusions . 1 . sternoclavicular joint should berd backward as best as the subject can , 2 . the best finish effect can be obtained when both hands lift behind and parallel the ground , 3 . the rotation angle of the trunk should be within go degrees under the circumstance of hands lifting behind and paralleling the ground 经由结果讨论得知，受试者在冲线时，一、颈关节应尽最大能力向后弯曲，二、双手向后摆置成与地面平行时，具有最佳的冲线效益，三、躯干扭转时，在不影响双手后摆成与地面平行的情况下，以不超过90度为范围。
