Mechanical Properties and Failure Mode of Proximal Screw Fixation Technique Using Locking Compression Plate for Proximal Interphalangeal Arthrodesis in Horses: An Ex Vivo Study.

Objective:  The aim of this study was to measure the mechanical properties and failure mode of an model of proximal interphalangeal arthrodesis in horses with different methods of proximal screw fixation using a locking compression plate.

Study Design:  Pastern joint arthrodesis with a 3-hole 4.5-mm narrow locking compression plate was performed on 20 forelimbs of equine cadavers, randomized into four groups based on the fixation method and type of proximal screw used: unicortical cortex, bicortical cortex, unicortical locking, bicortical locking.

Histologic and immunohistochemical evaluation of biocompatibility of castor oil polyurethane polymer with calcium carbonate in equine bone tissue.

OBJECTIVE To evaluate the efficacy of castor oil polyurethane polymer with calcium carbonate for use in a unicortical ostectomy on the dorsal surface of the third metacarpal bone of horses. ANIMALS 6 adult horses. PROCEDURES A unicortical ostectomy was created on the dorsal surface of both third metacarpal bones of each horse.

Effect of postoperative xylazine administration on cardiopulmonary function and recovery quality after isoflurane anesthesia in horses.

Objective: To evaluate equine cardiopulmonary function and recovery quality after administration of 0.25 or 0.50 mg/kg xylazine intravenously (IV) during recovery.

3-D technology used to accurately understand equine ileocolonic aganglionosis.

Ileocolonic aganglionosis (ICA) is the congenital and hereditary absence of neurons that constitute the enteric nervous system and has been described in various species including humans - Hirschsprung's disease - and horses - overo lethal white syndrome (OLWS). Hirschsprung's disease affects circa 1 in 5,000 live births. At best, this disease means an inability to absorb nutrients from food (humans).

Effect of ephedrine and phenylephrine on cardiopulmonary parameters in horses undergoing elective surgery.

Objective: To assess the cardiopulmonary effects of ephedrine and phenylephrine for management of isoflurane-induced hypotension in horses.

Study Design: Prospective randomized clinical study.

Animals: Fourteen isoflurane-anesthetized horses undergoing digital palmar neurectomy.

Effect of pressure support ventilation during weaning on ventilation and oxygenation indices in healthy horses recovering from general anesthesia.

Objective: To determine if pressure support ventilation (PSV) weaning from general anesthesia affects ventilation or oxygenation in horses.

Study Design: Prospective randomized clinical study.

Animals: Twenty client-owned healthy horses aged 5 ± 2 years, weighing 456 ± 90 kg.

Arthrodesis of the equine proximal interphalangeal joint: a biomechanical comparison of 3-hole 4.5 mm locking compression plate and 3-hole 4.5 mm narrow dynamic compression plate, with two transarticular 5.5 mm cortex screws.

Objectives: To compare the biomechanical characteristics of 2 arthrodesis techniques for the equine proximal interphalangeal joint (PIP) using either a 3-hole 4.5 mm locking compression plate (LCP) or 3-hole 4.5 mm narrow dynamic compression plate (DCP), both with 2 transarticular 5.

Bilateral sinus cysts in a filly treated by endoscopic sinus surgery.

Bilateral cysts in the frontal and caudal maxillary sinuses in a filly treated by endoscopic sinus surgery (sinoscopy) and triangulation technique are described. Sinoscopy has the advantage of being a minimally invasive technique and permits a complete inspection of the frontal and maxillary sinuses, which is not possible through flap sinusotomy.

Characterization of equine adipose tissue-derived progenitor cells before and after cryopreservation.

In horses, stem cell therapies are a promising tool to the treatment of many injuries, which are common consequences of athletic endeavor, resulting in high morbidity and often compromising the performance. In spite of many advantages, the isolation of stem cells similar to human, from equine adipose tissue, occurred only recently. The aim of this study was to isolate equine adipose tissue-derived progenitor cells (eAT-PC), to characterize their proliferative potential, and to study their differentiation capacity before and after cryopreservation.
