The superficial digital flexor tendon (SDFT) runs down the palmar aspect of the equine limb superficial to the deep digital flexor tendon. It originates from the superficial digital flexor muscle and inserts primarily on the proximal aspect of the middle phalanx (P2), with some fibers continuing distally. The SDFT functions to flex the fetlock and pastern joints and provides elastic energy storage during locomotion. While the SDFT is less directly involved in the navicular region than the DDFT, injuries to the SDFT in the pastern and fetlock can alter overall limb biomechanics and indirectly affect loading of the foot. It is commonly injured in the mid-cannon region in performance horses. This information is for educational purposes only. Always consult with a licensed veterinarian for diagnosis and treatment of your horse.
Chronic inflammation and remodeling of the proximal sesamoid bones from repetitive loading and suspensory ligament traction.
Chronic inflammation and remodeling of the proximal sesamoid bones from repetitive loading and suspensory ligament traction. Signs include: Chronic low-grade forelimb lameness; pain on palpation of the sesamoid bones; positive flexion test; enlarged, remodeled sesamoids on radiographs; seen in young racehorses and sport horses.; Consult veterinarian for specific symptoms.
