How many joints does the carpus contain?
Three
antebrachiocarpal joint,
middle carpal joint,
and carpometacarpal joint
Which joints in the carpus always communicate with each other?
Middle carpal and carpometacarpal
What is a critical consideration when performing regional anesthesia in the proximal palmar metacarpal region?
Risk of puncturing the carpometacarpal joint, palmar outpouchings of the carpometacarpal joint extend distad
In which joint are injuries most commonly found in the carpus of horses?
Antebrachiocarpal joint and middle carpal joints
Name the proximal row of carpal bones
radius; the proximal row of carpal bones (radial carpal, intermediate carpal, and ulnar carpal bones);
Name the distal row of the carpus
distal row of carpal bones (second,
third, and fourth carpal bones);
Name the bones of the metacarpal region
metacarpal (MC) bones II, III, and IV; the accessory carpal bone; and occasionally a first carpal bone (but rarely a fifth).
Name the ligaments of the carpus and tendons related to the carpus
1.intercarpal ligaments,
2. collateral ligaments,
3. fibrous joint capsule,
4. palmar carpal ligaments.
TENDONS
1. extensor carpi radialis and 2.** common digital extensor** tendons as well as their sheaths span the carpus dorsally and dorsolaterally, respectively
3.** lateral digital extensor tendon** courses over the lateral side of the carpus, as does the tendon of the
4. ulnaris lateralis
5. flexor carpi ulnaris
6. flexor carpi radialis
7. carpal sheath with SDFT, DDFT, radial head of DDFT, median artery and n.
How are the extensor carpi radialis and common digital extensor tendon are maintained against the surface of the carpus?
surface of the carpus by the extensor retinaculum located at the distal radius approximately at the level of the physeal scar.
