WHAT IS ANGULAR LIMB DEFORMITY?
Synchronous growth of the radius and ulna is essential for normal limb development. Premature closure of a physis (growth plate) in the radius or ulna may lead to deformity and shortening of the limb. The severity of the deformity depends on the segment of bone that is affected and the pet’s potential for further growth.
HOW IS ANGULAR LIMB DEFORMITY TREATED?
Treatment depends on the maturity of the animal, the severity of deformity and the growth potential of the remaining bone growth plates. Treatment often includes 1 or more surgeries and may involve placement of a plate and screws or external skeletal fixator. An osteotomy is the surgical division of a bone and shifting of the divided ends to change the alignment of the bone or to alter the pets weight bearing load.
If closure of a bone is identified early, the patient is young, and the remaining bone growth plates still have growth potential, then treatment could be as simple as a small ostectomy and placement of a graft to prevent bone closure.
Prognosis for normal appearance and function depends on severity and the growth potential of the remaining bones growth plates. The presence of elbow and carpal deformity and/or arthritis will also negatively affect the outlook for the patient.
