Soft tissue procedures may be insufficient in the treatment of recurrent shoulder dislocations, especially if there is a bone defect at the anterior glenoid border. New concepts and defect measurement methods in shoulder instability guide shoulder surgeons in the treatment modalities. Bone block methods come to the fore in the treatment of bone defects. The block options to be used in glenoid anterior margin reconstruction can be autograft or allograft. The history of surgical treatment has evolved from the Latarjet procedure to new techniques and graft options that can better fit the native glenoid anatomically. These procedures can also be performed fully arthroscopically, with advanced technological tools and fixation materials.
