Evaluating the efficacy of hinged elbow braces in reducing passive valgus forces after ulnar collateral ligament injury-A biomechanical study.

ABSTRACT:

Purpose

This biomechanical study aimed to investigate the effectiveness of a hinged elbow orthosis in reducing passive valgus forces following medial ulnar collateral ligament (UCL) injuries of the elbow joint. The hypothesis tested was that a hinged elbow orthosis reduces these passive valgus forces.

Methods

Eight fresh frozen cadaveric elbow specimens were prepared and tested under three scenarios: intact ligaments, simulated UCL rupture and application of a hinged elbow brace after simulated UCL rupture. Valgus instability was assessed using a custom testing set-up and the Optotrak motion capture system. Statistical analysis was conducted to compare the results across scenarios.

Results

Intraclass correlation (ICC) calculation showed that the testing set-up was rel
