About The Webinar

This presentation begins with a recap of the anatomy of the carpus with an emphasis on the features of relevance to disease. The palmar fibrocartilage is a passive resistor of carpal hyperextension, and multiple other short ligaments are critical to the stability of the joint.
Imaging of the carpus typically involves plain radiography, though stressed views are of use for this joint, since instability is a common cause of carpus-related lameness. Computed tomography is also useful in a number of situations, including where small fracture fragments of the cuboidal bones, distal radius/ulna and proximal metatarsals are suspected.
Diseases of the carpus including instability associated with hyperextension injury (not necessarily the same entity in dogs and cats) and collateral ligament injury are covered individually. Hyperextension injury management typically necessitates pan carpal arthrodesis in the dog, but may be amenable to joint salvage in the cat, depending on the nature of the injury. Fractures of the first row of cuboidal bones should be considered for dogs with carpal pain. They often demonstrate a typical orientation and may or may not be amenable to fixation (the alternative approach often involving pan carpal arthrodesis).
Finally stenosing tenosynovitis of the abductor pollicis longus tendon of insertion and fractures of the metacarpal bases are discussed, with emphasis on their management.
