B2 genoid in a young active meam

An active man in his late 40s presented with severe pain and loss of motion in his left shoulder.
His x-rays on presentation are shown below.



His axillary "truth" view shows a B2 glenoid with retroversion, biconcavity and posterior decentering.



 He elected to have a ream and run operation. His films at two years are shown below.

 His postoperative view shows his prosthetic humeral head centered on a mono concave, retroverted glenoid.



At two years after surgery, his motion was excellent and painless as shown in this video he kindly gave us permission to show here. He challenges us to decide which was the operated shoulder. He thanks all his fellow ream and runners for the inspiration to put in the work. He states he is also 15 - 20 lbs lighter (note we have just been through the holiday season).





Comment: This case shows a bone-preserving approach to the B2 glenoid in comparison to the bone removal associated with some posteriorly augmented glenoid components

or with "corrective" anterior reaming.


As well it avoids the risks and limitations associated with a prosthetic glenoid component.
