However, it is unknown whether it is a superior option when compared to total shoulder arthroplasty in young patients. We compared the survivorship and reasons for revision between pyrocarbon resurfacing and the best-performing anatomic total shoulder arthroplasty prostheses from a large national arthroplasty registry.<\/p>\n\n\n\n<p>Methods &#8211; The study population included all primary shoulder arthroplasty procedures undertaken for osteoarthritis (OA) in patients aged &lt;65 years and reported to the Registry between September 2004 and December 2022. The cumulative percentage revision (CPR) was determined using Kaplan-Meier estimates of survivorship and hazard ratios (HRs) from Cox proportional hazard models adjusted for age and sex. Two cohort groups were compared: pyrolytic carbon (pyrocarbon) humeral hemi-resurfacing (PHR) and 5 anatomic total shoulder replacement (aTSA) prosthesis combinations with the lowest CPR at 5 years, using polyethylene cemented glenoids and restricted to patients aged &lt;65 years.<\/p>\n\n\n\n<p>Results &#8211; A total of 403 PHRs with a mean age of 52.5 years and 1,952 aTSAs with a mean age of 58.6 years were analyzed. Twenty PHRs (5.0%) and 123 aTSAs (6.3%) were revised, with a CPR at 10 years of 7.7% (95% confidence interval [CI] 4.7-12.4) and 9.0% (95% CI 7.4-11), respectively. The PHR and aTSA revision risk did not differ. The predominant reason for revision was implant breakage (35%) for PHR, compared with loosening (33.9%) for aTSA.<\/p>\n\n\n\n<p>Conclusion &#8211; Pyrocarbon humeral resurfacing arthroplasty has a comparable survivorship in younger patients compared with best-in-class anatomic total shoulder arthroplasty.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Authors: Andrew McBride, Robert Hurley, David Gill, Peiyao Du, Phil Duke, Fraser Taylor, Greg Hoy, Richard Page, Mark RossPublication Date: October 2025Journal: Journal of Shoulder and Elbow SurgeryArticle link: https:\/\/www.jshoulderelbow.org\/article\/S1058-2746(25)00752-9\/abstract Abstract: Background &#8211; Pyrocarbon hemi-resurfacing and pyrocarbon hemi-arthroplasty is an emerging class of arthroplasty that demonstrates superior survivorship compared with metal hemiarthroplasty and resurfacing.
