An In Vitro Biomechanical Comparison of Equine Proximal Interphalangeal Joint Arthrodesis Techniques: Two Parallel Transarticular Headless Tapered Variable Pitch Screws Versus Two Parallel Transarticular AO Cortical Bone Screws Inserted in Lag Fashion

Objectives: To compare the mean number of cycles to failure under axial compression of equine proximal interphalangeal (PIP) joint arthrodesis constructs created by 2 parallel transarticular Acutrak Plus screws (AP‐TS) or 2 parallel transarticular 5.5 mm cortical screws inserted in lag fashion (AO‐T...

Description
Summary:Objectives: To compare the mean number of cycles to failure under axial compression of equine proximal interphalangeal (PIP) joint arthrodesis constructs created by 2 parallel transarticular Acutrak Plus screws (AP‐TS) or 2 parallel transarticular 5.5 mm cortical screws inserted in lag fashion (AO‐TLS). Study Design: Paired in vitro biomechanical testing of 2 methods of stabilizing cadaveric adult equine forelimb PIP joints. Sample Population: Cadaveric adult equine forelimbs (n=5 pairs). Methods: For each forelimb pair, 1 PIP joint was stabilized with AP‐TS and 1 with AP‐TLS. The 5 construct pairs were tested for cyclic fatigue under axial compression. Mean number of cycles to failure for each fixation method were compared by a paired t‐test within each group with statistical significance set at P
