55 year old avid handball player with a B2 glenoid - is any plastic needed?

 A 55 year old highly competitive handball player from several states away presented with activity-limiting pain and stiffness in his right shoulder and the x-rays below showing posterior decentering of the arthritic humeral head on a biconcave B2 glenoid

Because of his love for the impact sport of handball, he elected a ream and run procedure (https://www.reamandrun.com/), which avoids the risks and limitations associated with a plastic glenoid component. The humeral prosthesis was a smooth stem (no ingrowth surface) inserted with impaction autografting and a low filling ratio. No preoperative CT scan or 3D planning were used. He had general anesthesia without a brachial plexus block.

At seven years after his surgery he reported a successful return to competitive handball with full shoulder function. Along with his report, he sent us the x-rays below showing secure fixation of the humeral prosthesis without stress shielding, a humeral head centered in the glenoid, and a remodeled, concentric glenoid concavity. 

Comment: In some quarters there is enthusiasm for treating this type of shoulder pathology with a posteriorly augmented glenoid component or an "inlay" glenoid component. As shown here, our experience is that a plastic glenoid component is often not necessary for a durably excellent clinical outcome.
