Traumatic dislocations of the shoulder can result in a bony Bankart lesion (tear). The head of the humerus (ball of upper arm bone) is stabilized against the glenoid (socket of the shoulder joint) by a combination of muscles, labrum, and ligaments. When the humeral head is forced out of place in a dislocation, the soft tissues stretch or tear, and in some cases, bone is fractured off the glenoid rim, resulting in a bony Bankart lesion.
Typically, dislocations that result in bony Bankart lesions leave the shoulder joint unstable and prone to repeat dislocations. Patients with pain and instability following a dislocation and bony Bankart injury are candidates for bony Bankart repair surgery. Reconstructive surgery of the glenoid using a bone graft can address the deficient bone, repair torn soft tissues, and restore the shoulder’s function and stability. Dr. Steven Chudik developed instruments and techniques to perform the surgery arthroscopically.
