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).
The cost of such versatility is an increased risk of injury. It is important that family physicians understand the anatomy of the shoulder, mechanisms of injury, typical physical and radiologic findings, approach to management of injuries, and indications for referral.he glenohumeral joint is one of the most commonly dislocated joints. Ninety percent of shoulder dislocations are anterior (Figure 5) , 3 with most of the others being posterior. 9 Inferior dislocations (luxatio erecta) are rare and often are accompanied by neurovascular injury and fracture.
