What is glenohumeral subluxation?
Glenohumeral subluxation is defined as symptomatic translation of the humeral head on the glenoid without complete separation of the articular surfaces. Subluxation of the glenohumeral joint is usually transient: the humeral head returning spontaneously to its normal position in the glenoid fossa.
