Joint dislocation, commonly referred to as dislocation, is a phenomenon in which a bone is dislocated from a joint, usually resulting in a strain or tear of the ligaments or, in severe cases, a fracture. The shoulder joint is the most mobile joint in the human body and can meet the different needs of people in life and sports, but it is also the most unstable joint in the human body. A blow, a fall, a cramp, a forceful ball throw, a traffic accident, etc., may cause a dislocation of the shoulder joint. Therefore, among all joint dislocations in the human body, shoulder dislocation has the highest percentage, 45% to 50%. The vast majority of traumatic shoulder dislocations occur in people between the ages of 14 and 34. Because this group is more active, the recurrence rate after the first dislocation is high, with 90% of patients abroad reporting recurrences, also known as “habitual dislocation”. This is also called “habitual dislocation”, which means that the dislocation is triggered when the patient’s shoulder joint is in a specific position, such as the “shooting” in basketball, “dunking” in volleyball, “serving” in tennis, and the stroke in backstroke. When riding on a bus, dislocation occurs when pulling the handrail and encountering the emergency brake. Even everyday actions such as wearing clothes and stretching sleeves, spreading arms and rubbing backs, raising arms and hanging clothes can cause dislocation of the shoulder joint, which can become a habit and cause damage to the relevant joints, ligaments, bones and even nerves, seriously affecting the function of the shoulder joint. Whenever a dislocation occurs again, some patients come to the hospital to have it fixed, while others can reset themselves because the joint capsule is already loose due to repeated dislocations. These patients often have some psychological barriers in their daily life due to the fear of dislocation, and are afraid to exercise or raise their hands above their heads. In order to reduce habitual dislocation of the shoulder joint, different treatment methods should be adopted according to the specific situation. After the first traumatic dislocation of the shoulder joint, you should go to a professional hospital for examination. The joint should be fixed in a stable position for 2 to 4 weeks after the reset; active functional exercises should also be performed after the release of fixation to facilitate the restoration of joint function. In recent years, due to the development of arthroscopic surgery, minimally invasive wound surgery techniques have been used to repair the torn glenoid labrum ligament after the first shoulder dislocation for young people, athletes, and sports-loving patients, in order to reduce the chance of future recurrence and the complexity of retreatment after recurrence. The results of arthroscopic surgery can reduce the chance of recurrence to less than 10% to 20% in these patients with high recurrence rates. In conclusion, the importance of preventing habitual shoulder dislocations should not be underestimated. Habitual dislocations not caused by injury are best treated with rehabilitation, while those caused by injury are best treated with surgery. Only by transforming an unstable joint into a stable one will you have the opportunity to enjoy unrestricted movement and reduce the chance of arthritis.
