[THE TREATMENT OF TRAUMATIC SHOULDER INSTABILITY - THE OPEN APPROACH VS. ARTHROSCOPIC APPROACH]

Shoulder dislocation occurs when the head of the humerus disengages from the glenoid bone. About 95% of shoulder dislocations are traumatic, while the other 5% are not trauma-related in a patient with predisposing factors such as generalized ligamentous laxity. Ninety percent of shoulders dislocate anteriorly from direct force on the arm in the "ABER" position (Abduction- External Rotation). Usually, dislocations are accompanied by injuries to the shoulder that may lead to recurrent anterior shoulder instability and in the long-run, osteoarthritis of the shoulder joint. In the case of traumatic shoulder dislocation in the younger population or competitive sport players, accompanied with bone injury on X-ray's (Bony Bankart or Hill-Sachs), surgical treatment is recommended as soon as possible to avoid recurring dislocation and further joint damage. There are several options to treat recurrent shoulder instability, including soft tissue procedures, bone procedures, and a combination of these procedures. Surgery can be performed by an open or arthroscopic approach.
