Bankart lesion

Signs and symptoms

Bankart lesions are characterized by recurrent shoulder instability and widespread shoulder discomfort. Some individuals may experience catching, locking, or popping feelings in their shoulders. The majority of Bankart lesion patients have primary or recurrent anterior shoulder dislocation.

Diagnosis

The diagnosis is usually initially made by a combination of physical exam and medical imaging, where the latter may be projectional radiography (in cases of bony Bankart) and/or MRI of the shoulder. The presence of intra-articular contrast allows for better evaluation of the glenoid labrum. Type V SLAP tears extend into the Bankart defect.

Treatment

Arthroscopic repair of Bankart injuries have good success rates. However, a study has found that nearly one-third of young adult patients require further surgery for continued instability after the initial procedure, with higher re-operation rates in those less than 20 years of age. Options for repair include an arthroscopic technique or a more invasive open Latarjet procedure, with the open technique tending to have a lower incidence of recurrent dislocation, but also a reduced range of motion following surgery.
