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).
The axillary nerve is located at the proximal end, against the shoulder girdle. Dislocation of the humerus's glenohumeral joint, has the potential to injure the axillary nerve or the axillary artery. Signs and symptoms of this dislocation include a loss of the normal shoulder contour and a palpable depression under the acromion. The radial nerve follows the humerus closely.
