Five-year Outcome of Arthroscopic Partial Humeral Head Resurfacing-Dr. Leo Pauzenberger, M.D., PhD.

Video Transcription

Video Summary

This presentation discusses arthroscopic partial humeral head resurfacing using a specific implant, showing a surgical technique involving transhumeral portals and retrograde reaming. A five-year study of 30 patients revealed significant, stable improvements in clinical scores, pain reduction, and shoulder function. Smaller and larger implant sizes had similar outcomes. Revision rates were 13.3%, mainly due to osteoarthritis progression, particularly in cases with glenoid cartilage defects—now considered a contraindication. No neurological complications occurred, and implant fixation was confirmed histologically. Overall, the technique is a safe, effective option for young, active patients with focal humeral cartilage defects.
