General and local [corrected] aetiologic factors in canine osteochondrosis

Observations based on necropsy findings in 89 dogs with osteochondrosis are presented. Osteochondrosis was most common in the elbow joint, followed by the shoulder joint, the stifle and the hock joint. There were 59 male and 30 female dogs, and the mean age was 2 years. The high frequency of bilateral lesions and the occurrence of osteochondrosis in more than one pair of joints in 25 of the 89 dogs indicates that general factors are important. The various manifestations of osteochondrosis and their frequency are reported. Various local factors believed to be important for the occurrence of the lesions within the joints are also considered.
