The most evident of the tomographic findings were bilateral subchondral sclerosis and irregular periosteal reaction in medial and lateral proximal phalanx margin, characterizing fetlock collateral ligament enthesopathy in 5 limbs (25%) and desmopathy in 3 limbs (15%) (Figures 4 and 5). They limit movement of the bones of a joint to one plane. This horse has large irregularity in the middle of the sagittal ridge. The suspensory ligament holds the back of the equine ankle in place and prevents overextension of the fetlock during the weight-bearing phase of a horse's stride. Alternative etiologies include avulsion fractures related to the collateral ligament … Horse tendon injury occurs most frequently within the hoof capsule and the sheath around the tendon, likely from repetitive excessive loading. Diagnosis of ligament … ... which are located in the back of the fetlock joint. Ultrasound can be used to provide a quick and reliable diagnosis of collateral ligament rupture, allowing for early initiation of treatment.

Raul Bras, a farrier and equine veterinarian at Rood and Riddle Equine Hospital in Lexington, Ky., has extensive experience in caring for tendon and ligament injuries in horses. Collateral ligaments of the coffin joint, fetlock joint and hock joints. In comparison, a ligament is a semi-elastic structure that connects bone to bone, often bridging one or more joints to provide external stabilization to that region. fetlock joint. Source of Fetlock Bone Fragments - ... Dr. Alexandra Carlson An osteochondral (bone/cartilage) fragment seen on radiographs in the joint of a young horse is commonly an osteochondritis dissecans (OCD) fragment. Fig. Metacarpophalangeal (Fetlock) Joint Your wrist can bend in both directions - as can a horse's fetlock. Common examples include the suspensory ligament, but also lateral and medial collateral ligaments that aid to stabilize joints such as the fetlock, carpus, and stifle joints. Its function is to support the fetlock joint during the weight-bearing phase of the stride. The suspensory ligament originates at the back of the cannon bone, passing down the back of the leg before dividing into two branches which attach to the sesamoid bones. When treated properly, a horse with a wound of the fetlock, metacarpus, metatarsus, carpus, or tarsus that does not extend into a supporting structure or synovial cavity has a good prognosis for an excellent cosmetic outcome and soundness. Back to Table of Contents. An 11-year-old Haflinger mare was presented to veterinarians at the UC Davis Equine Surgery and Lameness Service on Nov. 21, 2017, for a lameness evaluation. Meniscal and cruciate ligaments of the stifle. Using this approach, the fetlock joint is flexed to a dorsal angle of 225o, the needle is placed through the skin at the level of the midbody of the lateral proximal sesamoid bone, and then through the palmar annular ligament, 3 mm axial to the palpable palmar border of the lateral proximal sesamoid bone, immediately palmar to the palmar digital neurovascular bundle. Fetlock collateral ligament rupture should be considered in horses with acute lameness and fetlock swelling with or without palpable joint instability. Lameness is an abnormal gait or stance of an animal that is the result of dysfunction of the locomotor system. Disorders of the Carpus and Metacarpus in Horses.

The horse is in dorsal recumbency on a surgery table. It originates from the top of the back of the cannon bone and continues down to the fetlock region. There are several soft tissue structures associated with the fetlock; the joint is stabilised by collateral ligaments, located on the inside and the outside of the joint. Tendon/ligament abnormalities were identified in 57% horses on MR and 47% of horses on ultrasound images. 4. Scar tissue is much weaker than normal tendon and ligament fibers, making the horse prone to re-injury despite extensive layups and prolonged treatment periods following the original injury. Short ligaments: Join neighbouring carpal bones either within the same row, or in the adjacent row. Horse. Every horse owner knows that tendons and ligaments a vital component of our horse’s limbs and that tendon and ligament health are very important for their soundness.

With ligament damage, this can mean choosing a differentially wide shoe to better support the injured side, providing the horse with specialized hospital shoes that cover the bottom of the foot and are designed to quickly open, giving ready access to caregivers, or even creating shoes specifically for that horse, used most often for horses with limb deformities or abnormalities. When doubt persists, the horse should be confined and a second radiographic examination carried out 14 to 21 days later. Figure 1. 51 In 24 horses that underwent both ultrasound and CT evaluation of the stifle, desmopathy of the medial collateral ligament was diagnosed in 5 horses with CT and 4 horses with ultrasound. ... fetlock joint and will be affected in any arthropathy.
