Abstract

A Cocker Spaniel presented for recurrence of right forelimb lameness 33 months following transcondylar screw placement for a humeral intracondylar fissure. Elbow radiographs showed no evidence of implant-related complications. Standard CT scale reconstruction images failed to demonstrate implant failure. Extended CT scale reconstruction images revealed a fracture through the mid-portion of the screw. Revision surgery confirmed the implant failure; the screw was replaced and the lameness subsequently resolved. Extended CT scale reconstruction images allow detailed assessment of metal implants and should be considered when implant failure is suspected.

Keywords: computed tomography; dog; screw fracture.
