Biomechanical differences of the anterior and posterior bands of the ulnar collateral ligament of the elbow.

Purpose: The main purpose of this study was to examine the functional characteristics of the anterior and posterior bands of the anterior bundle of the ulnar collateral ligament (UCL).

Methods: Six cadaveric elbows were tested using a digital tracking system to measure the strain in the anterior band and posterior band of the anterior bundle of the UCL throughout a flexion/extension arc. The specimens were then placed in an Instron materials testing machine and loaded to failure to determine yield load and ultimate load of the UCL.

Biomechanical comparison of screw versus plate/screw construct for talonavicular fusion.

Background: Talonavicular fusion is performed for a variety of indications. This study examined the effects of fixation techniques on plantar pressures, construct stiffness, and strength.

Materials And Methods: Eight matched pairs of cadaveric lower extremities were axially loaded intact and after talonavicular fixation with a 3.
