Ununited medial epicondyle of the humerus in a dog : a case report

A Labrador crossbreed female dog was presented for a right forelimb lameness of 4.5 years' duration. The severity of the symptoms had suddenly increased 8 months earlier, after a trauma. Surgical exploration did not reveal calcification either in the joint capsule or in the flexor tendons. The fragment was intraarticular. No evidence of bone repair was noticed at surgery which confirmed imaging findings. The histologic findings were very much like those observed with chronic fragmented coronoid process. Finally, the lameness, although suddenly exacerbated by a trauma, was already present. All these facts led to a final diagnosis of a true "ununited medial humeral epicondyle", a term introduced to describe the lack of fusion of the caudal part of the humeral medial epicondyle
