Instability Shoulder Surgery
Instability occurs when the head of the upper arm bone is forced out of the shoulder socket. This can happen as a result of sudden injury or from overuse of the shoulder ligaments.
The two basic forms of shoulder instability are subluxations and dislocations. A subluxation is a partial or incomplete dislocation. If the shoulder is partially out of the shoulder socket, it eventually may dislocate. Even a minor injury may push the arm bone out of its socket. A dislocation is when the head of the arm bone slips out of the shoulder socket. Some patients have chronic instability. Shoulder dislocations may occur repeatedly.
Patients with repeat dislocation usually require surgery. Open surgical repair may require a short stay in the hospital. Arthroscopic surgical repair is often done on an outpatient basis. Following either procedure, extensive rehabilitation, often including physical therapy, is necessary for healing.
Treatments
Arthroscopy
Arthroscopy allows the orthopaedic surgeon to insert a pencil-thin device with a small lens and lighting system into tiny incisions to look inside the joint. The images inside the joint are relayed to a TV monitor, allowing the doctor to make a diagnosis. Other surgical instruments can be inserted to make repairs, based on what is with the arthroscope. Arthroscopy often can be done on an outpatient basis. According to the American Orthopaedic Society for Sports Medicine, more than 1.4 million shoulder arthroscopies are performed worldwide each year.
Open Surgery
Open surgery may be necessary and, in some cases, may be associated with better results than arthroscopy. Open surgery often can be done through small incisions of just a few inches.
Recovery and rehabilitation is related to the type of surgery performed inside the shoulder, rather than whether there was an arthroscopic or open surgical procedure.
