Morphometric data on the accessory ligament of the deep digital flexor tendon in the equine hindlimb

摘要

Desmopathy of the accessory ligament of the deep digital flexor tendon (ALDDFT) in the hindlimb has recently been described as a cause of lameness in horses. However, there is limited morphometric data on this ligament. In the present study, the ALDDFT was carefully dissected in 165 hindlimbs that were collected from an abattoir. Length, width (lateral-to-medial) and thickness (plantar-to-dorsal) of the ligament were measured. It was found that the ALDDFT may be absent in a minority of horses, but when it was present the general morphology was variable. The ALDDFT can be a single rectilinear structure ranging from slender or poorly developed to quite large and can be divided, in part or in its entirety, into two or three bundles.
