Incidence and Prevalence: The shoulder is the most commonly dislocated joint in the body, and glenohumeral dislocation accounts for more than half of all joint dislocations in the US. Approximately 95% of the glenohumeral dislocations are anterior dislocations, and 4% are posterior dislocations (Park). An international estimate of the annual incidence of glenohumeral dislocation is 17 per 100,000 individuals (Wilson).
If glenohumeral external rotation ROM is greater at 90 degrees of abduction than at 45 degrees of abduction, suspect a muscle flexibility deficit of the subscapularis Normal glenohumeral external rotation ROM is 90 degrees Glenohumeral Internal Rotation ROM Measurement Performance Cues: Stand above the patient Stabilize scapula in neutral - use forearm to prevent protraction Be precise with humeral abduction (90 degrees if possible) and horizontal abduction (maintain 0 degrees) Normal is 60 degrees of isolated glenohumeral internal rotation ROM Glenohumeral Flexion ROM Measurement
