The Effect of the Central Post and Screw Constructs on the Univers Revers Total Shoulder System.

Introduction: The use of lateralized glenoid components in reverse total shoulder arthroplasty (rTSA) is increasing to avoid scapular notching and improve strength and impingement-free range of motion. However, maximizing glenoid lateralization increases stress at the bone-baseplate interface. The ideal type and length of central fixation remains a subject of debate.
