    Abstract / Zusammenfassung

    Summary The existing study is part of an interdisciplinary project involving three different universities, with the aim of attaining more information about the widespread, presumably multifactorial, disease named Osteochondrosis dissecans (OCD). This paper provides, in its literature-overview an introduction into the Osteochondrosis- complex, the state of research with regard to pathogenesis, etiology, frequency and location and finally the background on x-ray procedures and OCD-diagnosis in hock and stifle joints. Within the frame-work of this survey, 630 warmblood foals ranging in age from three to ten months and 596 of their mothers were examined via x-ray imaging. Overall 19.7% of the 630 examined foals and 11.4% of the 596 mares showed detectable osteochondrotic lesions. It was detected that 10.5% of the foals (n=630) showed osteochondrotic lesions at the sagittal ridge of the distal tibia, 1.6% at the lateral trochlea tali and 1.2% at the distal tibia and the trochlea tali at the same time. It became obvious that the overall frequency of osteochondrotic changes at the hock is 13.3%. Colts were affected significantly more often than fillies. Stifle-joints of foals were affected by 7.3% (n=630) with osteochondrotic lesions. None of these joints showed isolated boney fragments. It was observed that the frequency of osteochondrotic changes especially in the stifle-joint was governed by age. The osteochondrosis incidence varied within the different offspring groups considerably and ranged from 0 to 41.7%. The mares showed 8.9% (n=596) OCD-lesions at the sagittal ridge of the tibia and 1 % at the lateral trochlea tali. The frequency of OCD in the stifle-joint was 1 %. Data analysis shows that foals from mares with OCD-lesions are significantly more likely to develop OCD-lesions than foals from unaffected mares.
