carpal joint(redirected from carpal joint osteochondrosis)
a series of joints that includes the antebrachiocarpal, formed by the distal ends of the radius/ulna and the proximal carpal row, the intercarpal joint between the two rows of carpal bones, the carpometacarpal joint(s) between the distal row of carpal bones and the metacarpal bone(s). The joint capsule is continuous throughout all of the joints and has three major sacs, the radiocarpal, the intercarpal and the carpometacarpal sacs. Called also the knee. See also carpus.
carpal joint luxation
a major injury in horses while racing, usually involving fractures of carpal bones and rupture of ligaments. The animal is unable to bear weight on the leg and there is excessive mobility and crepitus. In dogs and cats, violent hyperextension of the carpus damages soft tissue support for the joint so that the animal walks with the carpus on or near the ground.
carpal joint osteochondrosis
osteochondrosis dissecans and subchondral cysts occur in the carpal joints of horses, causing lameness, pain on passive extension and sometimes distention of the joint capsule.
carpal joint subluxation
may occur in the dog as a result of trauma but is also recorded as a familial disease associated with the simultaneous occurrence of hemophilia A.
