1.Why does habitual dislocation of the shoulder joint occur? Habitual dislocation of the shoulder joint often occurs after a traumatic injury. The first dislocation will cause the ligaments that keep the shoulder joint stable to tear off. During repositioning, the joint is reset, but the torn ligaments are often difficult to restore to their original position, so the shoulder joint is missing an important stabilizing structure in front of it. After that, every time you move to a more dislocation-prone angle, you will be dislocated due to the lack of the necessary blocking structure in front of you, which causes habitual dislocation of the shoulder joint. 2. Does everyone who has a dislocated shoulder become habitually dislocated? No. Modern research suggests that whether a shoulder dislocation becomes a recurrent dislocation is closely related to the age of the patient when the dislocation first occurred. If the first dislocation occurs in a young person, for example, before the age of 30, then most of these patients will become recurrent dislocations because the shoulder joint mobility is well recovered after repositioning and the patient usually has a greater range of motion in the shoulder joint. If the first dislocation occurs in a middle-aged or older patient, such as someone over the age of 40, it is often difficult to restore the range of motion of the shoulder joint to the previous level after dislocation, so the chance of recurrence is relatively low. 3.What should I do if I have a recurrent dislocation of the shoulder? If the shoulder joint has been dislocated more than once before, i.e. recurrent dislocation, then according to the more recognized research results at home and abroad, I am afraid that only surgical treatment can completely eliminate the risk of future recurrence. Some patients may be able to reduce the risk of recurrence by limiting the mobility of their shoulder joint. In general, dislocation will only occur if the shoulder joint is moved to a certain position. However, as mentioned earlier, recurrent dislocations tend to occur in younger patients, where there is a lot of daily upper extremity activity, and it is often difficult to completely eliminate movements that could result in dislocation. 4.What kinds of surgery are available to treat recurrent shoulder dislocations? There are many types of surgery, which can be broadly divided into two types: incisional surgery and arthroscopic surgery. Incisional surgery is a traditional surgery with a large incision under direct visualization, which is generally more invasive and slower to recover than arthroscopic surgery. Arthroscopic surgery is a new surgical approach that has emerged in the last decade or so. Generally, the procedure requires only a few small incisions and is performed with the aid of arthroscopic instruments, resulting in less trauma and a better recovery for the patient. The choice of surgery depends largely on the severity of the injury. If the bony damage is too severe, arthroscopic surgery cannot be performed and an incision will be required. It is recommended that if there is more than one dislocation of the shoulder joint, surgery should be performed as soon as possible for better results. In addition, a 3D CT examination should be done before surgery to determine the way of surgery. 5.When is the best time to operate after a recurrent dislocation? If the dislocation is already recurrent, the sooner the surgery is performed, the better the result will be. This is because each dislocation will aggravate the damage to the ligaments, joint capsule and bones around the shoulder joint, thus increasing the difficulty of surgery. 6.How long does it take to recover after arthroscopic surgery? After surgery, the affected limb needs to be protected by a triangular scarf or sling on the chest for 6 weeks to allow the repaired ligaments to heal, and after 6 weeks, functional rehabilitation of the affected limb begins. At this time, the affected limb can be used for activities of daily living, but not for sports. By six months after surgery, you can start some less strenuous physical activities, such as running, sit-ups, breaststroke, etc., but not freestyle, backstroke, butterfly, tennis or badminton. By one year after surgery, you can do any sports. 7.How much does arthroscopic surgery cost? If you have Beijing Municipal Health Insurance, you can save a lot, in that case it will cost about 10,000 RMB. However, if you have to pay for it completely out of pocket, it will cost about 40,000 RMB.
