Glenoid reconstruction using an autograft prior to arthroplasty

Glenoid reconstruction using an autologous bone graft is indicated when bone loss is too extensive to allow for the stable implantation of a shoulder prosthesis. A bone graft, most commonly harvested from the resected humeral head or, in exceptional cases, from the iliac crest, is fixed to the glenoid to restore its volume and orientation. Once the reconstruction is complete, the shoulder prosthesis is implanted under better conditions, improving its stability and long-term fixation. This technique enables the treatment of complex cases whilst optimising functional outcomes and the durability of the arthroplasty.
