Shoulder dislocations

Often due to a shallow glenoid socket compared to the diameter of the shoulder joint causing ligaments or the capsule to stretch or tear the labrum making the joint dislocate or sublux. 97% of dislocations are anterior, but joints may also dislocate posteriorly and inferiorly. Dislocations can be caused by trauma due to significant force such as a traffic accident or a minimal force depending upon the strength of the surrounding ligaments and muscles. Treatment includes relocating the shoulder into joint followed by a period of rest in a sling and physiotherapy. Open or arthroscopic surgery may be considered after the initial episode or if shoulder dislocation is recurrent.
