Surgical Treatment of Congenital Radial Head Luxation in a Cat by Ostectomy of Radial Head

Congenital radial head luxation was diagnosed in a 7-month-old, neutered female cat that presented a right forelimb lameness. Clinical and radiographic examination revealed a caudolateral luxation of the right radial head, which was treated by radial head ostectomy. For months, postoperative radiographic recheck documented remodelling of the radial head, without humero-radial conflict, and clinical examination revealed resolution of lameness and restoring of the normal elbow range of motion. To the authors' knowledge, this is the first case report of a congenital radial head luxation in a caudolateral direction in a cat that was successfully managed surgically with radial head ostectomy.
