Zur Dicke des Gelenkknorpels an der Trochlea tali proximalis und der Cochlea tibiae beim großwüchsigen Hund

Osteochondrosis dissecans (OCD) is a well known disease in dogs that usually affects convex joint surfaces of largebreed, fastgrowing dogs aged four to seven months. Nine percent of the canine CCD-cases affect the hock joint, more precisely the trochlea tali proximalis (Montgomery et al., 1994). OCD is regarded as a result of a disturbed enchondral ossification. The cartilage thickness of the trochlea tali proximalis and the cochlea tibiae was measured in ten adult largebreed dogs. The measurement was done photooptically. In each joint the cartilage thickness was determined on eleven points at the trochlea tali proximalis and two points at the cochlea tibiae. At the trochlea tali proximalis it decreased from proximal to dorsal. Almost no difference in cartilage thickness was recorded between dorsal und distal. Regarding the proximal measuring points the cartilage was statistically significantly thicker at the lateral ridge than at the medial ridge. In contrast the cartilage thickness was almost equal at the two ridges proximodorsal, dorsal and distal. At the cochlea tibiae the thickness at the two measuring points was similar Usually the cartilage was statistically significantly thicker in male than in female adult largebreed dogs.
