T-plate for middle carpal and carpometacarpal arthrodesis in a dog.

Partial arthrodesis was performed for carpal hyperextension injury in a dog. T-plate application for middle carpal and carpometacarpal arthrodesis was associated with low patient morbidity and allowed normal pet activity without clinical lameness. Radiography revealed bony healing of arthrodesed joints, reactive bone formation over the dorsal aspect of the plate, and periarticular osteophyte formation. A guarded prognosis is advised for degenerative joint disease that may lead to decreased range of motion of the antebrachiocarpal joint.
