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).
