For a front leg, this is when the lower leg is in front of the horse, i.e. angled forward, while the caudal phase is when the leg is underneath the horse, i.e. angled backward. For a hind leg, the cranial phase occurs when the lower leg is under the body of the horse, and the caudal phase is when the limb is out behind the body of the horse.
In the early 1900s, dysfunction of the sacroiliac joint was a common diagnosis associated with low back and sciatic nerve pain. [18] However, research by Danforth and Wilson in 1925 concluded that the sacroiliac joint could not cause sciatic nerve pain because the joint does not have a canal in which the nerves can be entrapped against the ...
Skeleton of the lower forelimb. Each forelimb of the horse runs from the scapula or shoulder blade to the third phalanx (coffin or pedal) bones. In between are the humerus (arm), radius (forearm), elbow joint, ulna (elbow), carpus (knee) bones and joint, large metacarpal (cannon), small metacarpal (splint), sesamoid, fetlock joint, first phalanx (long pastern), pastern joint, second phalanx ...
The sacroiliac joint is a paired joint in the pelvis that lies between the sacrum and an ilium. Due to its location in the lower back, a dysfunctional sacroiliac joint may cause lower back and/or leg pain. The resulting leg pain can be severe, resembling sciatica or a slipped disc.
Lameness is most commonly associated with injury to synovial joints, or those joints containing articular cartilage, a joint capsule, and a synovial membrane.Joint disease may affect the joint capsule and synovial membrane, articular cartilage, subchondral bone (the bone underneath the cartilage), menisci, or any ligaments associated with the joint.
Hip joint : Ball-and-socket joint made up of the acetabulum of the pelvis and the femur. It is very stable. Stifle joint (femoropatellar joint): actually composed of three joint compartments: the femoropatellar joint, the medial femorotibial joint, and the lateral femorotibial joint, which are stabilized by a network of ligaments. The stifle ...
The joint capsule may also be completely ruptured and the articular portion of the bones exposed to view. [51] An osselet is inflammation of the metacarpophalangeal joint (fetlock) of the equine front leg. [52] Osselets are a result of trauma, such as hard, heavy, or fast use, a slip or fall, or a direct blow to the joint. [53]
A flexion test is a preliminary veterinary procedure performed on a horse, generally during a prepurchase or a lameness exam. The purpose is to accentuate any pain that may be associated with a joint or soft-tissue structure, allowing the practitioner to localize a lameness to a specific area, or to alert a practitioner to the presence of sub-clinical disease that may be present during a pre ...
