The deep digital flexor tendon (DDFT) runs down the back of the leg and attaches on the bottom surface of the coffin bone. Contraction of the deep digital flexor muscle will flex the digit. At rest, the DDFT applies a constant traction to the bottom surface of the coffin bone, which is counteracted by the laminae holding the coffin bone to the ...
The deep digital flexor (DDF) tendon runs down the back of the cannon and soft tissue in that area and under the navicular bone before attaching to the back of the coffin bone. The DDF tendon flexes the coffin joint, and the navicular bone acts as a fulcrum that the DDF tendon runs over. [2]
Deep digital flexor: 3 tendons of the deep digital flexor muscle travel distally and join at the carpus, where they pass through the carpal canal, and travel distally along the back of the leg, finally inserting into the palmar side of the third phalanx. Below the knee/hock, the tendon is superficial to the suspensory ligament, but deep to the ...
Long toes force the horse to pivot (break over) further forward over the toe. The toe acts as a lever arm, and its increased length makes it harder for the heels to rotate off the ground. This increases strain on the deep digital flexor tendon and the ligaments of the navicular bone. [10] An abscess has ruptured out of the coronary band of this ...
Deep digital flexor tenotomy Main article: Treatment of equine lameness § Deep digital flexor tendon tenotomy Because the rotation of P3 is exacerbated by continued pull on the deep digital flexor tendon, one approach to therapy has been to cut this tendon, either in the cannon region (mid-metacarpus) [ 4 ] or in the pastern region.
Injury to the superficial digital flexor tendon as a cause of curb is as common as injury to the long plantar ligament. Injury to the deep digital flexor tendon as a cause of curb is less common, and collateral ligament desmitis in the tarsocrural joint is uncommon.
The main tendon in the hoof is the deep digital flexor tendon, which connects to the bottom of the coffin bone. The impact zone on the bottom of the hoof includes the sole, which has an outer, insensitive layer and a sensitive inner layer, and the frog, which lies between the heels and assists in shock absorption and blood flow.
The distal check originates from the palmar carpal ligament and attaches to the deep digital flexor tendon, approximately 2/3-way down the metacarpus. Plantar ligament: in the hind leg, originates on the calcaneus, running down the lateral side of the tarsus, attaches to the 4th tarsal and 4th metatarsal bones.
