The cases were diagnosed in our clinic during a 3-year period. The pigs were examined clinically, then one side of the pigs was radiographed (because osteochondrosis is assumed to be a generalized condition). Radiographs were made for the coxofemoral joints (24), femorotibila joints (24), tarsi (16), humeroradioulnar joints (20), and distal physis of the ulna and carpi (37).Results: Two categories of radiographic changes were recognized: 1) those affecting the articular epiphyseal cartilage complex; and 2) those affecting the physeal growth plates of the long bones. The frequency of osteochondrotic lesions at the distal physeal plate of the ulna was 32 of 37 (86.4%) of the distal ulna examined. The changes at the distal physeal plate of ulna were graded on a scale from 0-5 according to the size, location, and extent of the lesions, as previously reported. Examples of lesions encountered in different locations were illustrated.Implications: Radiography is a useful tool for diagnosing osteochondrosis in pigs. The distal physeal plate of the ulna is a suitable site to be radiographed to establish the diagnosis of this generalized condition. ER -
