Osteoarthritis (OA) of articular processes (APJs), OA of intertransverse joints (ITJs), intervertebral disc (IVD) mineralisation, impingement of spinous (SPs) and transverse (TPs) processes and spondylosis were scored. Breed differences in prevalence and severity of pathologies were analysed by linear regression analysis and by calculating Spearman's rank correlation coefficients (\n r<\/jats:italic>\n \n s<\/jats:italic>\n <\/jats:sub>\n ).\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n In Warmblood horses, the prevalence of OA of APJs, impingement of SPs and TPs was respectively 90%, 36%, and 35%, significantly higher than in the other breeds (\n p<\/jats:italic>\n \u2009<\u20090.001). In Konik horses, IVD mineralisation (40%) and spondylosis (10%) were more frequent than in Warmbloods and Shetland ponies (\n p<\/jats:italic>\n \u2009=\u20090.03). Severity score for OA of ITJs was highest in Shetland ponies (\n p<\/jats:italic>\n \u2009<\u20090.001). For impingement of SPs, severity score was highest in Warmbloods (\n p<\/jats:italic>\n \u2009=\u20090.03), and of TPs lowest in Shetland ponies (\n p<\/jats:italic>\n \u2009=\u20090.003). For all parameters, except for spondylosis in Shetland ponies, there was a positive correlation between percentage of vertebrae affected and age, with IVD mineralisation scores increasing faster in Konik horses (\n p<\/jats:italic>\n \u2009<\u20090.001). In all breeds, there was also a positive relation between scores of severity and age for OA of APJs and ITJs and for IVD mineralisation, with severity scores increasing faster in Shetland ponies (\n p<\/jats:italic>\n \u2009=\u20090.04). Strong left\/right correlations of the severity scores were seen for OA of the APJ, ITJ, impingement of TPs, and paramedian spondylosis (\n r<\/jats:italic>\n \n s<\/jats:italic>\n <\/jats:sub>\n \u2009=\u20090.74\u20130.86, all\n p<\/jats:italic>\n \u2009<\u20090.001).\n <\/jats:p>\n <\/jats:sec>\n \n Main limitations<\/jats:title>\n Clinical histories were not available.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n There are distinct breed differences between prevalence and severity of osseous pathologies of the lumbar spine.
