Test for stifle collateral ligament damage: the stifle is held still, while the distal limb is abducted (to test for damage to the medial collateral ligament) or adducted (to test for lateral collateral ligament damage). Excessive movement by the distal limb relative to the stifle suggests rupture of the collateral ligament.
It is used as a salvaging procedure to save the horse with an injury that disrupts the stability of a joint, such as septic arthritis, failure of the suspensory apparatus, subluxation, fracture, or collateral ligament rupture, or may be used to treat chronic osteoarthritis. It is most commonly used to treat disease of the coffin, fetlock ...
Curb is defined in older literature as enlargement secondary to inflammation and thickening of the long plantar ligament in horses. [1] However, with the widespread use of diagnostic ultrasonography in equine medicine, curb has been redefined as a collection of soft tissue injuries of the distal plantar hock region.
The joint is stabilized by paired collateral ligaments which act to prevent abduction/adduction at the joint, as well as paired cruciate ligaments. The cranial cruciate ligament and the caudal cruciate ligament restrict cranial and caudal translation (respectively) of the tibia on the femur. The cranial cruciate also resists over-extension and ...
Obel grading system. The severity of lameness is qualified using the Obel grading system: [16] Obel grade 1: Horse shifts weight between affected feet or continuously lifts feet up. It is sound at the walk but displays a shortened stride at the trot. Obel grade 2: Horse displays a stilted, stiff gait, although is willing to walk.
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 Thoroughbred Owners and Breeders Association (TOBA) statistics on racing related career ending injuries show that high grade races have a much lower rate of injury than low grade races. [94] While this could be attributed to many factors, including the quality of the horse, economics, or medications, the trainer still must make the decision ...
As the horse developed as a cursorial animal, with a primary defense mechanism of running over hard ground, its legs evolved to the long, sturdy, light-weight, one-toed form seen today. Good conformation in the limbs leads to improved movement and decreased likelihood of injuries. Large differences in bone structure and size can be found in ...
