Ultrasound diagnosis in spontaneous injury of the AL-SDFT
Spontaneous injury of the AL-SDFT (accessory ligament of the superficial digital flexor
tendon/proximal check ligament) may occur in performance horses. This study showed
ultrasonography as an adequate diagnostic technique for this lesion and indicates that
desmopathy (degenerative histological changes) of the AL-SDFT should be suspected in equine
athletes presenting a carpal canal syndrome and a proximal SDFT tendinopathy.
This study examined the carpal canal of lame horses represented with carpal canal syndrome
and/or proximal superficial digital flexor tendonitis based on clinical/radio-graphical findings
for four years. Ultrasound findings were compared to transverse and longitudinal scans of
seven adult horses without history of lameness.
Abnormal AL-SDFT findings were found in 45 horses. They included thickening, hypoechoic
areas and fiber pattern alteration. Most injuries were seen in performance horses, only four in
Musculoskeletal ultrasound is a very useful diagnostic device for evaluation of tendons,
muscles, nerves and joints in the equine athlete. Do you make use of it already?
