A Comparison Of Cyclic Valgus Loading On Reconstructed Ulnar Collateral Ligament Of The Elbow, Roshan Pradip Shah

Yale Medicine Thesis Digital Library

This study compares the biomechanics of early cyclic valgus loading of the ulnar collateral ligament (UCL) of the elbow repaired by either the Jobe technique or the docking technique. Better understanding of the biomechanical properties of each reconstruction may help surgeons choose the optimal surgical technique, particularly in planning earlier rehabilitation programs. Sixteen fresh frozen cadaver limbs (eight pairs) were randomized to either the Jobe cohort or the docking cohort. First intact UCLs were tested, followed by the repaired constructions. A Bionix MTS apparatus applied a constant valgus load to the elbows at 70o flexion, and valgus displacement was measured …
