Tissue engineering in wound repair: the three “R”s–repair, replace, regenerate. Horses are predisposed to traumatic wounds that can be labor intensive and expensive to manage. Skin has a considerable potential for efficient and functional repair however, while cutaneous repair is a regenerative process in the fetus, this capability declines in late gestation as inflammation and scarring alter the outcome of healing. The historical gold standard for replacement of lost skin is the autologous skin graft. However, the horse's lack of redundant donor skin limits the practicality of full-thickness grafting to smaller wounds; moreover, graft failure is relatively common in equi...
Comparison of three drilling techniques for carpometacarpal joint arthrodesis in horses. To evaluate 3 drilling techniques for arthrodesis of the equine carpometacarpal (CMC) joint. Methods: Experimental study. Methods: Cadaveric equine forelimbs (n=15). Methods: Limbs were divided into 3 groups (5 limbs each) to evaluate 3 drilling techniques: (1) use of a 4.5 mm drill bit inserted into the joint through 4 entry points and moved in a fanning motion; (2) a 5.5 mm drill bit inserted through 2 entry points to create 3 nonfanned drill tracts (3 drill technique); and (3) a 4.5 mm drill bit used in a 3 drill technique. The CMC joint was disarticulated after drilling, and cartilage and ...
Treatment of carpometacarpal osteoarthritis by arthrodesis in 12 horses. To evaluate arthrodesis as a treatment for carpometacarpal joint osteoarthritis (CMC-OA). Methods: Case series.
