OBJECTIVE: To determine the effects of water temperature and cure time on cast strength. STUDY DESIGN: Prospective randomized experimental study. METHODS: Two water temperatures were tested, 23°C (cold) and 42°C (warm). Cast constructs were made of 4-inch fiberglass casting material over a rubber mandrel. Each construct was divided into 3 segments and tested in 4-point bending at 0.5, 1, and 24 hours. Stiffness and bending moment, cumulative energy, and angular deformation at yield and failure were recorded and analyzed by using repeated measures ANOVA...

OBJECTIVE: To test the feasibility and safety of an arthroscopic imbrication of the medial glenohumeral ligament (MGHL) and the subscapularis tendon with knotless anchors in dogs. STUDY DESIGN: Cadaveric study. SAMPLE POPULATION: Ten limbs. METHODS: Cranial and caudal arms of the MGHL were imbricated with a 2.9- or a 2.4-mm knotless anchor.

OBJECTIVE: To describe normal antebrachiocarpal joint kinematic motion during axial loading and to describe the effect of palmar radiocarpal ligament (PRL) and palmar ulnocarpal ligament (PUL) transection on this motion. SAMPLE POPULATION: Ten forelimbs from 5 adult greyhound cadavers. METHODS: Limbs were placed in a custom jig and computed tomography images of limbs were obtained in neutral and extended positions. The translation and rotation of the intermedioradiocarpal bone (RCB), ulnar carpal bone, and accessory carpal bone were described relative to the radius through rigid body motion analysis...

OBJECTIVE: To determine the effect of a prototype dynamic laryngoplasty system (DLPS) on arytenoid abduction. STUDY DESIGN: In vitro experimental. STUDY POPULATION: Ten equine larynges. METHODS: Dissected larynges were mounted, and the right arytenoid was maximally abducted for testing. A left-sided laryngoplasty (LP) was performed by using a strand of No. 2 FiberWire and a FASTakII anchor. Phase 1 involved tightening the suture, without the DLPS device in place, in 1-mm increments and acquiring a digital image of the rima glottidis at each increment...
