The glenohumeral joint (from ancient Greek glene eyeball puppet doll + -oid ‘form of’ + Latin humerus shoulder) or shoulder joint is a multiaxial synovial ball and socket joint and involves articulation between the glenoid fossa of the scapula (shoulder blade) and the head of the humerus (upper arm bone). Due to the very limited interface of the humerus and scapula it is the most mobile joint of the human body.
