A B2 glenoid in a 67 year old man - 12 year followup after a basic arthroplasty

 An active man in his mid 60s presented with pain and stiffness of his left shoulder. His radiographs at presentation showed an arthritic shoulder with the humeral head posteriorly decentered on a retroverted biconcave glenoid.


After discussion of the option of a reverse total shoulder, he elected to proceed with an anatomic total shoulder.

The procedure was performed without preoperative CT scanning or preoperative 3D planning. General anesthesia was used without a nerve block. The shoulder was exposed with a subscapularis peel preserving the long head of the biceps. The glenoid was conservatively reamed without attempting to alter version. A standard non-augmented all polyethylene glenoid with an ingrowth central peg was used. The standard length smooth humeral stem was fixed with impaction autografting. 

At the age of 80, he returned for routine followup. His 12 year x-rays (shown below) reveal no evidence of stress shielding, component loosening, or instability.

 He reported excellent comfort and function.
