Reconstruction of glenoid bone defects in shoulder instability with autologous bone.

Bone defects, both at glenoid and at the humeral side are a frequent sequel of anterior shoulder instability. Although the transfer of the coracoid process (Latarjet, Bristow procedures) has gained popularity in treating the glenoid defect, equal results can be achieved with the use of a bone graft, for which mainly a graft of the iliac crest is used. Recently, arthroscopic procedures have been developed, leaving the subscapularis muscle largely intact.
