Illustration of inflammatory bone pathology in a bone spavin specimen. The proximal intertarsal joint (1) appears to be normal but the more distal tarsal joints (2, 3) are obliterated. 2, distal intertarsal joint; 3, tarsometatarsal joint; 4, tibiotarsal joint (almost all movement here); 5, medial malleolus; 6, medial ridge of trochlea of the talus; 7, lateral ridge of the trochlea; 8, calcanean tuber; 9, most distal part of calcaneus; 10, central tarsal bone (Tc); 11, third tarsal bone (T3); 12, fourth tarsal bone (T4), 13, vascular canal for perforating tarsal artery [the canal is easier to see on the spavin specimen due to a more lateral camera angle]; 14, metatarsal 3 (cannon bone); 15, metatarsal 4 (lateral splint bone).
