What makes the shoulder joint dislocate?
Dislocation happens when a force overcomes the strength of the muscles and ligaments of the shoulder. This is usually when the arm is in a “ball-throwing” position. Sometimes the shoulder does not come out of the socket completely. It slips out partially and then returns to its normal position, this is called subluxation. The initial treatment would be to put the shoulder back into its socket. The shoulder will usually be sore for up to 2 weeks after a dislocation. Although the shoulder may subsequently appear normal with full motion and no pain, it will still remain unstable. This is because often the labrum and ligaments that restrain the shoulder would have been stretched and even torn from the socket (see Bankart lesion diagram below). This causes the shoulder to become loose especially in certain position or when the muscles around the shoulder are fatigued. In some cases, shoulder instability can occur without previous dislocation. This is common among athletes who do repetitive
