Movements taking place during abduction of shoulder joint are all except
Correct Answer: Medial rotation of scapula
Description: The total range of abduction is 180. Abduction up to 90 occurs at the glenohumeral joint. Abduction from 90 to 120 can occur only if humerus is rotated laterally. Abduction from 120-180 can occur if scapula rotates forwards on the chest wall. The humerus and scapula move in the ratio of 2:1 during abduction i.e. for every 15-degree elevation, the humerus moves 10 degrees and scapula moves 5degrees. During the early and terminal stages of elevation, the sternoclavicular and acromioclavicular joints move maximum respectively.
