Anatomy Of The Glenohumeral Joint

The glenohumeral joint is a ball and socket joint formed between the articulation of the rounded head of the humerus the upper arm bone and the cup like depression of the scapula called the glenoid fossa. The humeral head lies within the glenoid fossa a cavity that is lined by the glenoid labrum.

The glenohumeral gh joint is a true synovial ball and socket style diarthroidal joint that is responsible for connecting the upper extremity to the trunk.

Muscles and tendons of the shoulder. Abduction abduction requires external rotation to clear the greater tuberosity from impinging on the acromion. This joint is formed from the combination of the humeral head and the glenoid fossa of the scapula.

As mentioned previously the tendons of the rotator cuff muscles as they near their. Therefore if someone has an internal rotation contracture they can not abduct 120. The relative weakness of the capsule itself coupled with the bony structure of the glenohumeral joint means that the rotator cuff muscles are largely.

It is one of four joints that comprise the shoulder complex. Injury to the shoulder. Coracohumeral ligament attaches the base of the coracoid process to the greater tubercle.

Glenohumeral joint anatomy stabilizer and biomechanics. Reinforcement of the joint capsule. The active and passive soft tissue and bony stabilizers work together to provide glenohumeral stability.

Transverse humeral ligament spans the distance between the two tubercles of the humerus. Inferior glenohumeral ligament inferior part of blenoid labrum inferomedial part of humeral neck stabilise the glenohumeral. The glenohumeral joint motion is a result of a complex interplay between the passive and active stabilizers that require intricate balance and synchronicity.
