The B2 glenoid - a low tech approach to shoulder arthroplasty

 A sixty year old active man presented with pain and stiffness in both shoulders.

His preoperative x-rays show bilateral osteoarthritis with B2 type pathoanatomy: posterior bone loss and posterior decentering of the humeral head on a biconcave glenoid.








He had bilateral anatomic total shoulder arthroplasties performed with standard length impaction grafted humeral stems and standard all-polyethylene glenoid components inserted without preoperative CT scans, 3D planning, augmented glenoid components or interscalene blocks (see this link).

At three years after his surgeries, he has full painless function of his shoulders and these x-rays.


On both sides, there is good bony integration into the central peg and no evidence of osteolysis or radiolucent lines.
