Arthrodesis techniques in horses. When medical therapy and surgical treatments of an injured joint fail to return the animal to athletic performance or comfortable use of the limb, arthrodes is is a final option for some joints. Arthrodesis refers to the surgical fusion of a joint, resulting in bony ankylosis. Successful arthrodesis requires debridement of the articular cartilage through the calcified cartilage layer, exposing the subchondral bone; alignment of the joint into a weight-bearing position; and stabilization. The methods by which these steps are accomplished are variable, depending on the individual joint. There ar...
Diagnosis and treatment of ligamentous and meniscal injuries in the equine stifle. The accuracy of the diagnosis of ligamentous and meniscal injuries in the equine stifle has improved significantly in the last 20 years.
