2021 Annual Meeting Wrist & Elbow Access Pass-Biomechanical Comparison of Ulnar Collateral Ligament Reconstruction with and without Internal Bracing

Biomechanical Comparison of Ulnar Collateral Ligament Reconstruction with and without Internal Bracing

Video Transcription

Video Summary

This study investigated the biomechanical effects of adding an internal brace to ulnar collateral ligament (UCL) reconstruction in cadaver elbows. The internal brace, a strong suture aligned with the ligament, aims to reduce stress and improve repair stability. Results showed that UCL reconstruction with internal bracing provided similar valgus stability to standard reconstruction and the native ligament, but significantly increased stiffness and load-to-failure strength. Importantly, fewer graft ruptures occurred with internal bracing. Although limited by older specimens and lab conditions, findings suggest internal bracing may protect the graft and potentially accelerate rehab for overhead throwing athletes.
