Curb as a visible blemish is an easy diagnosis, as swelling in the distal lateral hock region is, by definition, curb. However, ultrasound is an essential tool in the diagnosis and in establishing a treatment plan. Diagnostic anesthesia (local or nerve blocks) can be helpful, but is not perfectly specific in this area.
Radial nerve paralysis will cause a dropped elbow and make it difficult to extend the affected limb. Suprascapular nerve damage will lead to atrophy of the main muscles of the shoulder (sweeny). Femoral nerve paralysis causes hyperflexion of the stifles, hocks, and fetlocks and the horse usually walks on the toe of the hind foot. [9]
Points of a horse. Equine anatomy encompasses the gross and microscopic anatomy of horses, ponies and other equids, including donkeys, mules and zebras.While all anatomical features of equids are described in the same terms as for other animals by the International Committee on Veterinary Gross Anatomical Nomenclature in the book Nomina Anatomica Veterinaria, there are many horse-specific ...
Injury to this ligament is an important cause of lameness in performance horses. The suspensory is a modified muscle, the equine equivalent of the interosseous muscle, which contains both tendon fibers and residual muscle fibers. [1] Interosseous ligaments: connect the cannon bone to each splint bone.
The anatomy of the forelegs begins at the scapula. This is the shoulder where the scapula contributes to the movement of the limb. The next bone is the humerus which leads onto the radius below. The radius is then connected to the bones of the knee. The carpus is located at the front of the knee and the pisiform is the back of the knee.
The coffin bone, also known as the pedal bone (U.S.), is the distal phalanx, the bottommost bone in the front and rear legs of horses, cattle, pigs and other ruminants. It is encased by the hoof capsule. In horses and other odd-toed ungulates it is the third phalanx, or "P3"; in even-toed ungulates such as cattle, it is the third and fourth (P3 ...
The annotation P2 stands for the middle phalanx, or pastern bone, and P3 denotes the distal phalanx, or coffin bone. The yellow lines mark the distance between the top and bottom part of the coffin bone relative to the hoof wall, showing the distal (bottom) of the coffin bone is rotated away from the hoof wall.
Gluteus profundus: originates from the superior ischiatic spine and shaft of the ilium, inserts into the femur. Allows the limb to rotate inward. Gracilis: originates from the pelvic symphysis all the way to the pubic tendon. Inserts into the medial femorotibial ligament, medial side of the tibia, and medial patellar ligament. Adducts the limb.
