Humeral head resurfacing is associated with less pain and clinically equivalent functional outcomes compared with stemmed hemiarthroplasty at mid-term follow-up

Purpose Humeral head resurfacing (HHR) is a less invasive, anatomic alternative to the conventional stemmed hemiarthroplasty in patients in whom isolated humeral head replacement is preferred. It was hypothesized that, in a mid-term cross-sectional subjective outcome analysis, HHR would have equivalent patient-reported and functional outcomes to stemmed hemiarthroplasty (HA).
