What is the carpal joint in horses?
The carpometacarpal joint is the articulation between the distal row of carpal bones and the second, third, and fourth metacarpal bones. Vertically oriented joints between adjacent cuboidal carpal bones within each row are referred to as intercarpal joints.
Do horses have Carpals?
The horse’s carpus or knee is also made of 8 bones called the radial carpal bone, ulnar, middle, accessory, first, second, third and fourth carpal bones. Only 50% of horses have the first carpal bone. These bones are in two rows forming 3 joints.
How many Carpals does a horse have?
Horse: 7 or 8 (presence or absence of first carpal bone) Carnivores: 7 (fusion of radial and intermediate carpal bones) Ruminant: 6 (first carpal bone is missing and II and III are fused)
What is the main function of the carpal bones?

What joints are present distal to the carpal joint in the horse limb?
The antebrachiocarpal joint between the radius/ulna and the proximal carpal bones. The middle carpal joint between the two rows of carpal bones. The carpometacarpal joint between the distal carpal bones and the proximal metacarpals.
Is the accessory carpal bone medial or lateral horse?
The accessory carpal bone forms the lateral border of the carpal canal. From lateral to medial, the ulnar carpal, the intermediate carpal, and the radial carpal bones complete the proximal row. The middle carpal joint lies between the proximal and distal rows of carpal bones.
Is carpus and Carpals the same?

The antebrachiocarpal and intercarpal joints are high motion joints while the carpometacarpal joint is low motion. The intercarpal and carpometacarpal joints communicate in all horses.
What is the carpometacarpal joint?
