Iliac crest bone grafting of the glenoid to address anterior subluxation after shoulder hemi-arthoplasty

This case illustrates the difficulties encountered in shoulder arthroplasty for the patient who is below 50 years of age. There is a history of prior bankart repair for anterior shoulder instability without bone loss. The anchors were prominent and the patient referred to me for reconstruction. X-rays below indicate the slight anterior subluxation of the humeral head which was persisted even after the hemi-arthoplasty. A second operation was required to reconstruct the anterior glenoid using iliac crest bone graft and address the subluxation which was causing persistent pain. The patient was pain free after the correction of the subluxation. The subscapularis repair was intact during the entire process which made things easier.
