ICJR Interviews: Rotator Cuff Failure after Anatomic Shoulder Arthroplasty

    Poor functional outcome scores – the SPADI, ASES, SST, Constant, and UCLA, for example – as early as 6 weeks following anatomic shoulder arthroplasty are likely a sign of a rotator cuff in the process of failing.

    When comparing a group of shoulder arthroplasty patients who developed rotator cuff failure with a matched group of patients who had successful shoulder arthroplasty outcomes, researchers from the University of Florida in Gainesville found worse outcomes scores in the rotator cuff dysfunction group, and the differences were seen anywhere from preoperatively to 6 months after the procedure.

    Stiffness in active and passive forward elevation, also as early as 6 weeks after surgery, was a harbinger of rotator cuff dysfunction as well, and it may have been related to overstuffing the joint, said Stephen T. Ikard Jr., MD, now with the University Orthopaedic Clinic in Tuscaloosa, Alabama, Patients with rotator cuff dysfunction were significantly more likely to exhibit humeral head height above the greater tuberosity, he said.

    In addition, Dr. Ikard and his colleagues saw significantly more superior and anterior humeral head translations and significantly more glenoid radiolucent lines in the rotator cuff dysfunction group.
