Abstract
Distal sesamoidean ligament (DSL) injury is a recognized cause of lameness in horses. The purpose of this study was to describe the contrast-enhanced computer tomography (CE-CT) findings in horses with injury to the DSL compared to a control group without injury to the DSL. Medical records of horses referred for CE-CT between 2008 and 2015 were reviewed. Cases were selected retrospectively based on a CE-CT imaging finding of injury to the DSL. Three horses had DSL injury as the only finding, while the remaining horses had one or more concomitant injuries. DSL injury and fetlock trauma and/or suspensory branch desmitis were the most frequent injury combinations. CE-CT can be of value in diagnosing DSL injury. The high number of concurrent DSL and fetlock and/or suspensory lesions suggests that further investigation should be considered when evaluating horses with injuries related to either of these structures.
