Resumo: | Locomotor conditions are the most frequent causes of discontinuity of horses? training and performance. Radiology is the most used noninvasive technique for the identification of bone diseases in horses due to its portability and economic viability. The aim of this study was to investigate bone maturity and prevalence of radiographic abnormalities (RA) in Thoroughbred horses between 18 and 24 months of age, raised and commercialized in Brazil, prior to the beginning of training, and to correlate bone maturity and radiographic abnormalities with longevity and athletic performance. Radiographic images obtained through direct digital radiology between 2012 and 2015 were evaluated by two experienced veterinarians. In study 1, 286 radiographic images obtained in dorsopalmar view of the left carpus were evaluated. The distal epiphysial closure stage of the radius was evaluated and classified in A, B or C. The results were submitted to regression analysis and adjusted to linear and quadratic models. In the study 2, purchase exams of 100 horses with at least 18 radiographic projections were evaluated. The radiographic studies were classified as without (G1) or with radiographic abnormalities (G2), and had their anatomical location described. To each of the RA observed, a severity score was assigned that summarized forming an individual general severity radiographic score (IGSRS). The horses on G2 were separated by IGSRS in 3 groups. To investigate the prevalence and anatomical location of the RA, a descriptive statistical study of frequency was performed with comparison by chi-square test. The multivariate discriminant analysis technique was used to evaluate the significance of the group separation. All animals had their athletic performance obtained, including both qualitative and quantitative information, and a control group was formed of 100 different animals from those evaluated in groups 1 and 2. The severity scores of the RA on G2 were correlated to the horses? athletic performance. All the data obtained were analyzed considering the level of statistical significance of 95%. The linear regression demonstrates the influence of age at first start over the total number of races and over the duration of the athletic campaign in months. Of the 100 animals evaluated in the study 2, 7% did not present RA while 93% presented RA. Of the 645 RA observed, 75.97% had a severity radiographic score of 1. The most prevalent RA were the changes detected on the proximal sesamoid bones in the thoracic and pelvic limbs. Horses that ran for the first time between 30 and 35 months of age and had a frequency of participation in races of approximately once a month had the most enduring athletic campaigns. The most prevalent radiographic abnormalities detected on purchase exams were in the metacarpophalangeal region, being mostly of a low degree of severity. The presence of moderate to severe radiographic abnormalities on the radiographic purchase exam of Thoroughbred foals at 18 months of age, decreased the duration of the athletic campaign and the athletic performance. |

O objetivo deste estudo foi investigar a maturidade ?ssea e a preval?ncia das anormalidades radiogr?ficas locomotoras em equinos da ra?a Puro Sangue Ingl?s entre 18 e 24 meses de idade, criados e comercializados no Brasil, antes do in?cio do treinamento, e correlacionar a maturidade ?ssea e as anormalidades radiogr?ficas ? longevidade e ao desempenho atl?tico destes animais. Imagens radiogr?ficas obtidas atrav?s de radiologia digital direta entre 2012 e 2015 foram avaliadas por dois m?dicos veterin?rios experientes. No estudo 1 foram avaliadas 286 imagens radiogr?ficas obtidas em posi??o dorsopalmar da regi?o carpiana esquerda. Foi avaliado o est?gio do fechamento epifis?rio distal do radio, classificando-o em A, B ou C. Os resultados foram submetidos ? an?lise de regress?o e ajustados aos modelos linear e quadr?tico. No estudo 2 foram avaliados exames de comercializa??o de 100 equinos com no m?nimo 18 proje??es radiogr?ficas. Os estudos radiogr?ficos foram classificados em sem altera??es radiogr?ficas (G1) ou com altera??es radiogr?ficas (G2), e estas tiveram sua localiza??o anat?mica descrita. A cada altera??o foi atribu?do um escore radiogr?fico de severidade que somados formaram um escore radiogr?fico de severidade geral individual (ERSGI). Os animais do G2 foram separados pelo ERSGI em 3 grupos. Para investigar a preval?ncia e localiza??o anat?mica foi realizado estudo estat?stico descritivo de frequ?ncia e compara??o pelo teste Qui-quadrado. A t?cnica multivariada de an?lise discriminante foi utilizada para avaliar a signific?ncia da separa??o dos grupos. Foram obtidas as informa??es do desempenho atl?tico todos os animais, visando avalia??o quantitativa e qualitativa, inclusive de um grupo controle formado de 100 animais diferentes dos avaliados nos grupos 1 e 2. Foi realizada a correla??o entre os escores de severidade das altera??es radiogr?ficas do G2 com o desempenho atl?tico dos animais. Todos os dados obtidos foram analisados considerando-se o n?vel de signific?ncia estat?stica de 95%. A regress?o linear demonstra influ?ncia da idade a primeira corrida sobre o n?mero total de corridas disputadas e sobre a dura??o da campanha atl?tica em meses. Dos 100 animais avaliados no estudo 2, 7% n?o apresentaram altera??es radiogr?ficas (AR) e 93 % apresentaram. Das 645 AR observadas, 75,97% possu?a escore radiogr?fico de severidade 1. As AR mais prevalentes foram as altera??es dos ossos sesam?ides proximais em membros tor?cicos e p?lvicos. Os equinos que correram pela primeira vez entre 30 e 35 meses de idade, e que apresentaram frequ?ncia de participa??o em corridas de aproximadamente uma vez ao m?s, tiveram as campanhas atl?ticas mais duradouras. As altera??es radiogr?ficas mais prevalentes nos exames de comercializa??o estavam localizadas na regi?o metacarpo falangeana sendo em sua maioria de baixo grau de severidade. A presen?a de altera??es radiogr?ficas de moderadas a severas no exame radiogr?fico de compra de equinos PSI jovens diminuiu a dura??o da campanha atl?tica e o desempenho atl?tico dos animais.Made available in DSpace on 2022-01-198T20:18:33Z (GMT).
