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.
[72] [73] Some occurrences of desmitis may be difficult to detect because the ligament is deep within tissue. An injury to the collateral ligament of the fetlock predisposes the horse to fetlock luxation, the second most common fatal injury. [74] [75]
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 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 ...
Arthrodesis is used in horses as a salvage procedure to treat severe breakdown injuries, such as failure of the suspensory apparatus, subluxation, fracture, or collateral ligament rupture. It is also performed in horses with osteoarthritis, primarily of the distal hock joints, to fuse these low-motion joints so they no longer produce pain for ...
Bone spavin indicated by A.. Bone spavin is osteoarthritis, or the final phase of degenerative joint disease (DJD), in the lower three hock joints.It usually affects the two lowest joints of the hock (the tarsometatarsal and the distal intertarsal joints), with the third joint, the proximal intertarsal, being the least likely to develop bone spavin.
