OSSIFICATION OF THE LATERAL CARTILAGE. SIDE-BONE.

both cartilages of one foot or the cartilages of both feet always become 
diseased together. 
Lungwitz, who examined 1,251 horses, states that side-bones occurred 
as shown in the annexed table :—

1. Ossification of the lateral cartilage occurs principally in heavy, 
coarse-bred horses. 2. The fore feet suffer more frequently than the 
Fig. 245.— A, Pedal bone; B, lateral 
cartilage cut through horizontally at 
the level of the pedal-joint; a, sur¬ 
face, formed by pedal and navicular 
bones, for articulation with coronet 
bone ; b, postero-lateral ligaments of 
navicular bone cut through ; b', por¬ 
tion of above which are attached to 
back of navicular bone ; c, the lateral 
ligament of navicular bone.
