A young German Shepherd Dog presented to the Small Animal Orthopedic Surgery Service on 8/13/12 for a six-week history of right forelimb lameness variably responsive to rest and carprofen. On presentation to the Cornell orthopedics service, the patient was otherwise healthy aside from abnormalities noted on orthopedic examination. A sedated orthopedic examination revealed evidence of both elbow and hip dysplasia. Due to greater severity of clinical signs, treatment of elbow dysplasia was prioritized over hip dysplasia. The patient underwent CT scan of both forelimbs, which confirmed a diagnosis of bilateral ununited anconeal processes without fragmented coronoid processes with associated mild osteoarthritis.

The patient returned to the hospital on 9/4/12 for bilateral surgical correction, and subsequently for several recheck appointments. This report will focus on the diagnosis, treatment, outcome, and post-surgical complications of ununited anconeal processes in the dog.
