Abstract
AbstractCongenital 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.
Highlights
The feline elbow is a composite joint made up of the humeroradial, humero-ulnar and proximal radio-ulnar articulations
Dogs that show mild clinical signs should be managed with a conservative approach and they should be strictly monitored with radiographies until the development of pain or progressive subluxation of the elbow warrant surgical intervention.[18]
Whenever a preventive approach is preferred, a surgical correction should be performed as early as possible to reduce the risk of secondary osteoarthrosis and to allow a better remodelling of the humero-radial articulation.[10,18,24]
Summary
The feline elbow is a composite joint made up of the humeroradial, humero-ulnar and proximal radio-ulnar articulations. Reports of the treatment of congenital radial head dislocations in dogs include conservative management, surgical reduction and stabilization, radial head ostectomy and arthrodesis.[5,13,15,16,17,18]. Only one report of a cat affected by bilateral CEL type I was diagnosed; no surgical correction was attempted.[19]. This case report describes the radial head ostectomy surgery used to treat a cat with congenital radial head luxation and its outcome
