Articular calcified cartilage canals in the third metacarpal bone of 2-year-old thoroughbred racehorses
We describe morphological aspects of the articular calcified cartilage
mineralizing front 'tidemark' in the distal joint surface of the third
metacarpal bone from 14 horses. Compositional backscattered electron scanning
electron microscopy and confocal scanning light microscopy were conducted on
polymethylmethacrylate (PMMA)-embedded medio-lateral slices. After maceration,
scanning electron microscopy (SEM) was used to study the calcified cartilage
surface in the 'wedges' intervening between the slices. An anatomically
reproducible clustering of canals in the calcified cartilage was found at one
site on the sagittal ridge in all the horses. The site is one that is relatively
less loaded during joint function. These canals through calcified cartilage
result from osteoclastic resorption (cutting cones) penetrating from bone
through to the non-mineralized hyaline articular cartilage. Their presence may
indicate a pathway for connection between bone and cartilage extracellular
fluid. In one horse, repair of such canals by plugging with new calcified
cartilage was demonstrated. Differences in the degree of mineralization of
regions of cartilage were seen in the combined compositional-cum-topographical
backscattered SEM images of the macerated 'tidemark' front. More-or-less
circular patches of lower mineralization density were frequently centred on (and
may possibly originate from) canals. These microanatomical features should be
searched for in other joints, at other ages and in other species to discover
their frequency and significance.
