Is surgery necessary for the treatment of a shoulder dislocation?
Traditionally, most orthopedic surgeons would not choose to operate on a patient after a first dislocation. Rather, after a brief period of immobilization, followed by physical therapy, the patient would gradually resume their normal activities. If the patient sustained a second, or recurrent, dislocation, then surgery was considered.
More recently, there is good scientific evidence to support early surgery, especially in young patients who are at a high risk for redislocation. If you sustain a shoulder dislocation, and are interested in surgery, discuss with your doctor the potential benefits of surgical versus nonsurgical treatment.
