Bony Bankart lesions represent a critical component in anterior shoulder instability, characterized by detachment of the anteroinferior glenoid rim with an osseous fragment. Accurate recognition and management of glenoid bone injury are essential to restore joint stability and prevent recurrence. The extent and location of the glenoid defect, as well as humeral head centering, are pivotal in treatment planning. Early arthroscopic reduction and internal fixation (ARIF) are recommended for repairable lesions within 3 weeks post-trauma, allowing for minimally invasive anatomical reconstruction. Imaging modalities such as CT and MRI provide complementary insights into osseous and soft-tissue pathology, while arthroscopic evaluation confirms lesion extent and associated injuries. Treatment strategies depend on fragment size: soft-tissue repair may suffice for minor defects (<12.5%), whereas medium (12.5–25%) and large lesions require bony reconstruction to achieve functional restoration. Chronic or resorbed fragments often necessitate osseous augmentation techniques such as Latarjet or Bristow procedures. Technical pearls include careful mobilization of the osteolabral fragment, precise anchor placement, and portal optimization for visualization. Proper early intervention and biomechanically sound reconstruction are decisive for successful long-term outcomes, particularly in athletic populations where glenoid bone loss is a leading cause of recurrent instability and surgical failure.
