joints that make up the shoulder complex |
The shoulder complex is formed by a series of unique articulations including the glenohumeral joint, sternoclavicular joint, acromioclavicular joint, and scapulothoracic articulation.

|
|
|
glenohumeral joint
|
The glenohumeral joint is formed by the convex head of the humerus and the concave glenoid fossa of the scapula.
Glenohumeral Snapshot: Osteokinematic motions: flexion, extension, abduction, adduction, medial rotation, lateral rotation Loose packed position: 55 degrees abduction, 30 degrees horizontal adduction Close packed position: abduction and lateral rotation Capsular pattern: lateral rotation, abduction, medial rotation |
convex/concave, Osteokinematic motions,loose packed, close packed position, and Capsular pattern.

|
sternoclavicular joint
|
The sternoclavicular joint is formed by the medial end of the clavicle and the manubrium of the sternum.
Sternoclavicular Snapshot: Osteokinematic motions: elevation, depression, protraction, retraction, medial rotation, lateral rotation Loose packed position: arm resting by the side Close packed position: maximum shoulder elevation Capsular pattern: pain at extremes of range of movement |
Osteokinematic motion, loose and close packed postion, and Capsular pattern |
|
|
acromioclavicular joint |
the acromioclavicular joint is formed by the acromion process of the scapula and the lateral end of the clavicle. Acromioclavicular snapshot: osteokinematic motions: anterior tilting, posterior tilting, upward rotation, downward rotation, protrction, and retraction. Loose packed position: arm resting by the side Close packed position: arm abducted to 90 degrees CApsular pattern: pain at extremes of ROM |
osteokinematic motion, loose and close packed positions, and capsular pattern |
|
|
Scapulothoracic joint |
it is formed by the body of the scapula and the muscles covering the posterior chest wall. |
