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 are currently accepted methods for arthrodesis of several joints in the horse; however, not all joints are amenable to arthrodesis. Case selection is an important aspect of performing arthrodesis procedures in horses.
