Its main job is to flex the leg, but it also plays a support role at the heel, where the tendon fibers fan out to pass over the navicular bone. Injuries in the lower section of this tendon, from mid-pastern into the foot, are common for sport horses.
What is the digital flexor tendon?
The forelimb superficial digital flexor tendon (SDFT) is an energy-storing tendon that is highly susceptible to injury during activities such as galloping and jumping, such that it is one of the most commonly reported causes of lameness in the performance horse.
Where is the deep flexor tendon?
The flexor tendons which are the deep digital flexor tendon (DDFT) and the superficial digital flexor tendon (SDFT) run down the back of the limb from the level of the knee/hock. The SDFT ends on the pastern and the DDFT end on the back of the pedal bone.
Where does the deep digital flexor tendon attach?
The deep digital flexor tendon (DDFT) is in excess of 50cm in length in the adult horse, attaching to muscle above the carpus (knee) in the forelimb and the hock in the hindlimb.What is the function of the SDFT?
The equine SDFT tendon is a complex hierarchal structure that transmits force from muscle to bone and stores energy through its stretching and recoiling action. It is a common site of pathology in athletic horses.
What does the superficial digital flexor tendon do in horses?
The superficial digital flexor tendon is responsible for the stabilization and support of the fetlock joint. (LLC, HorseDVM). A great deal of weight is supported by this very small cross-sectional area of flexor tendons, which is vulnerable to injuries.
Can a horse recover from tendonitis?
Recovery of Tendonitis in Horses Stall rest is advised but can be supplemented with restricted exercising such as a quiet walking in hand. The amount of time it takes is at least 3 months of inactivity to allow healing. Repeated scans may be necessary to evaluate the tendon prior to increasing the amount of exercise.
How long does a check ligament take to heal?
Ligaments are slow to heal and a full recovery can take 6 months or longer. Repeated ultrasound scans throughout the recovery period can help gauge the healing process and provide prognosis for any return to work.What is the stay apparatus in horse?
WHAT is the stay apparatus? The stay apparatus is a series of muscles, ligaments and tendons in the equine thoracic and pelvic limb, that stabilize the limb in a standing position.
How do you treat navicular in horses?Nonsurgical treatment of navicular syndrome consists of rest, hoof balance and corrective trimming/shoeing, and medical therapy, including administration of systemic antiinflammatories, hemorheologic medications, and intraarticular medications.
Article first time published onCan a horse recover from a hock injury?
Typically, this takes between six and nine months, although a mild mechanical lameness should be expected long term. In those horses unable to return to work, most will become pasture sound.
What causes tendon sheath inflammation in horses?
Acute tenosynovitis of the extensor tendon sheaths is often caused by trauma, such as a fall or hitting a jump with the carpus. This injury is common in event horses, in which it often is not associated with lameness. Diagnosis of acute tenosynovitis is based on clinical signs and ultrasonography.
Where does common digital extensor insertion?
OriginLateral epicondyle of humerus (common extensor tendon)InsertionExtensor expansions of digits 2-5ActionMetacarpophalangeal / Interphalangeal joints 2-5: Finger extensionInnervationPosterior interosseous nerve (C7, C8)
What does the SDFT connect to?
The SDFT arises from the superficial digital flexor muscle at the level of the carpus. At this level, the tendon combines with the accessory ligament (superior check ligament). The tendon passes distally on the caudal aspect of the limb, running through the carpal canal to the metacarpus.
What does SDFT stand for?

Where does the superficial digital flexor tendon originate?
On equine thoracic limb, the superficial digital flexor tendon (SDFT) arises from the superficial digital flexor muscle at the level of the carpus. Then the tendon combines with the accessory ligament (superior check ligament), passes distally on the caudal aspect through the carpal canal.
Can a horse be sound with a tendon injury?
Even a very mild lameness that resolves after a few days can indicate a tendon injury. Many horses remain sound even when there is significant damage to the tendon. Swelling or thickening of the tendon. This can be very noticeable or very subtle.
How do I strengthen my horses tendons?
Consistent forced exercise stimulates blood flow to healing areas. Movement reduces adhesion formation of tendon to tendon sheath and other tissues. Increasing load encourages tendon and ligament strengthening as long as overload does not take place. Exercise is also always good for a horse’s psychological well-being.
How do horses get tendonitis?
Tendinitis usually appears after fast exercise and is associated with overextension and poor conditioning, fatigue, poor racetrack conditions, and persistent training when inflammatory problems in the tendon already exist. Improper shoeing may also predispose to tendinitis.
How do you treat hock injuries in horses?
Joint injection is probably the most widely used and effective treatment for a horse with clearly identified problems in his lower hock joints. The injection puts anti-inflammatory agents directly into the space between the bones of the sore joints.
Where is the superficial digital flexor tendon horse?
The SDFT specifically stretches from below the knee or hock to the pastern bone2 (see figure 1) and is involved in flexing the digit. This tendon is under considerable loading stress, especially in disciplines involving high speeds or jumping, such as Three-Day Eventing.
What is a bowed tendon in horses?
Bowed tendon refers to tendon swelling that appears as a bow in the leg. Chronic stress or an injury can cause a bowed tendon. Treatment includes complete rest, anti-inflammatory drugs and gradual return to exercise. Full recovery can take 8 to 11 months. Premature work or stress can re-injure the tendon.
Do horses lock their legs when they sleep?
Thanks to specialized legs, however, a horse can lock its knees and fall asleep standing up — without falling over! A horse’s fear of predators also leads it to do most of its sleeping during the day. Just because a horse can fall asleep standing up doesn’t mean it never lies down, though.
Why do horses need reciprocal apparatus?
The stifle joint is directly connected to the hock and fetlock joints. This allows the hind limb to move in unison. … The reciprocal apparatus of the horse causes the stifle, hock and fetlock to flex in unison.
What is the near fore limb of a horse?
Near side is the side nearest the kerb, Off side is the side off the kerb. So in this country nearside is the left.
How do you know if you tore a ligament?
- Pain, often sudden and severe.
- A loud pop or snap during the injury.
- Swelling within the first 24 hours after the injury.
- A feeling of looseness in the joint.
- Inability to put weight on the joint without pain, or any weight at all.
How do you look after tendons?
Aside from the obvious call to avoid overuse through repetitive motions, the best way to take care of your tendons is to warm up your tissues before activities and maintain a gentle flexibility/stretching program. You’ll also be promoting positive results with all your other connective tissues, ligaments and fascia.
How long do you cold hose a horse's leg?
Cold hosing is simple, as long as your horse stands still. Run water from a garden hose over the injured area for twenty minutes. The trick, however, is to get some horses to stand quietly as the water runs down their legs for that length of time.
Can horses recover from navicular?
Navicular disease can be treated but rarely cured. Corrective trimming and shoeing is important to ensure level foot fall and foot balance. Often a rolled toe egg bar shoe is used to encourage early break over at the toe and good heel support.
Can you ride a horse with navicular?
Just like people with osteoarthritis, horses with navicular disease who are sedentary grow stiff and their body functions deteriorate. Turn your horse out in a pasture or paddock all day every day, if possible, and limit his time in the stall. If he’s still sound enough to ride, try to do so only on soft footing.
How serious is navicular in horses?
Navicular disease in horses is also known as Navicular syndrome. The result is the inflammation or degeneration of the navicular bone and its surrounding tissues, typically in the front feet of the horse. This disease can lead to significant or disabling lameness of a horse.
