Heart-related causes. Examples of heart-related causes of chest pain include: Heart attack. A heart attack is a result of a blood clot that's blocking blood flow to your heart muscle. Angina. Thick plaques can gradually build up on the inner walls of the arteries that carry blood to your heart.
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).
Posterior dislocation. For an uncomplicated posterior shoulder dislocation that is diagnosed within 6 weeks of injury, reduction in the ED is generally appropriate. A small humeral head defect is not a contraindication for attempting a closed reduction in the ED.owever, this anatomy also makes the glenohumeral joint the most unstable joint in the body. Anterior dislocations (in which the humeral head is displaced anteriorly in relation to the glenoid), account for as many as 95-98% of shoulder dislocations.
