Innovation in shoulder arthroplasty prosthesis design has led to a paradigm shift in recent years to “platform” (convertible) humeral stems that obviate the need for stem extraction when converting between non-constrained anatomic total shoulder arthroplasty and reverse arthroplasty.

In the article “Reverse total shoulder glenoid baseplate stability with superior glenoid bone loss” by Martin et al, the authors looked to quantify glenoid baseplate stability with worsening superior glenoid bone loss.
