A complex, multi-articulation joint composed of the tibia, talus, calcaneus, and tarsal bones that is subjected to substantial biomechanical stress during athletic activity. The tarsus is commonly affected by osteoarthritis, osteochondral disease, subchondral bone injury, and fractures, making it a frequent source of hindlimb lameness.
Tarsus
-
Tarsal Osteochondrosis Dissecans (OCD) & Osteochondral Fragments
Commonly affects the distal tibia, resulting in cartilage defects and loose fragments. Arthroscopic removal improves joint health and function.
-
Subchondral Bone Cysts (SBCs) of the Tarsus
Cystic lesions that may cause persistent lameness. Treatment includes imaging-guided planning, arthroscopic debridement, and screw placement.
-
Septic Arthritis of the Tarsal Joint
Serious infection requiring rapid surgical intervention and antimicrobial therapy.
