From: Clinicopathological findings in horses with a bi- or tripartite navicular bone
Case 3. Macroscopic pathological findings of the RF (A), LF (B), RH (C) and LH (D) navicular bones (panels 1: coffin joint articular surface, panels 2: transverse cut surface, formalin-fixed). The LH navicular bone shows marked sagittal indentation at its articular surface at the lateral side at one third of its length. On the transverse cut surface, cystic structures resembling those described in Case 2 can be appreciated at both sides of the connection site. The RF and RH navicular bones show only mild superficial sagittal indentation of the articular cartilage (picture insets), without changes of the subchondral bone; L = lateral side, M = medial side
