  • Title: Clinical and radiographic findings, treatment, and outcome in cattle with osteochondrosis: 29 cases (1986-1996).
    Author: Trostle SS, Nicoll RG, Forrest LJ, Markel MD.
    Journal: J Am Vet Med Assoc; 1997 Dec 15; 211(12):1566-70. PubMed ID: 9412686.
    Abstract:
    OBJECTIVE: To summarize the radiographic and clinical findings, treatment, and outcome in cattle with osteochondrosis diagnosed radiographically. DESIGN: Retrospective case series. SAMPLE POPULATION: 29 cattle with radiographic evidence of osteochondrosis. PROCEDURES: Medical records were reviewed, and owners or referring veterinarians were contacted for outcome assessment. Data were analyzed for potential interactions between osteochondrosis classification (osteochondritis dessicans vs subchondral cyst-like lesions), clinical and radiographic findings, treatment, and outcome, using Fisher's exact test and descriptive statistics. RESULTS: Osteochondrosis was associated with young, male, purebred cattle, clinical evidence of lameness, and radiographic evidence of concurrent degenerative joint disease. Osteochondritis dissecans and subchondral cyst-like lesions had similar clinical findings and outcomes but varied significantly in their radiographic distribution among joints. Osteochondrosis often manifests clinically as a unilateral condition, but bilateral lesions were often found (88%) when limbs were radiographically examined. Cattle managed conservatively tended to be culled (within 6 months of diagnosis because of lameness) more often than those managed surgically, despite the lack of treatment bias. CLINICAL IMPLICATIONS: Osteochondrosis in cattle is often associated with lameness or degenerative joint disease. Conservative management does not result in a favorable clinical prognosis for long-term, lameness-free survival, and more studies need to be completed to evaluate the efficacy of surgical treatment of osteochondrosis in cattle.
