Which joints communicate in a horse's leg?

Which joints communicate in a horse's leg?

• A. Femorotibial with stifle
• B. Carpus with stifle
• C. Medial patellar pouch with stifle; radiocarpal & proximal intercarpal; tibiotarsal & proximal intertarsal
• D. Hip with carpus

Answer: (C)

In the horse, several synovial compartments in the leg are connected, so fluid or infection can spread between them. The medial patellar pouch (the suprapatellar area) communicates with the stifle joint, meaning these two share a continuous synovial space. In the carpus, the radiocarpal joint communicates with the proximal intercarpal joints, and in the tarsus, the tibiotarsal joint communicates with the proximal intertarsal joints. These specific communications explain why distension or infection can involve multiple joints from a single source. The other pairings don’t reflect these established direct communications between joints in the horse’s leg.
