Osteocondrite dissecante da cabeça do úmero em cães: Estudo retrospectivo de 36 casos (1991-1996)

A osteocondrite dissecante da cabeça do úmero (OCD) é uma condição patológica da cartilagem articular, decorrente de distúrbio da ossificação endocondral. Foram analisados 36 casos de OCD em cães com idades compreendidas entre 5 e 24 meses, observando-se maior representação entre machos comparados com fêmeas (3,5:1). A maioria destes animais (80,6%) tinha recebido suplementação alimentar. Oito cães foram tratados conservativamente através de repouso e restrição alimentar, enquanto os demais foram submetidos a intervenção cirúrgica por meio de artrotomia e remoção do retalho de superfície articular da cabeça do úmero. Concluiu-se que a predisposição de algumas raças, associada ao desequilíbrio nutricional durante os primeiros meses de vida, são as causas determinantes da OCD, e que a cirurgia é a melhor terapia a ser empregada.

Prevalência e fatores associados da síndrome de Osgood-Schlatter em uma amostra populacional de adolescentes brasileiros

Osgood-Schlatter (O-S) syndrome, a pathology of the musculoskeletal system, exhibits high incidence in adolescence, a phase of accelerated bone growth. Detection of physiopathological mechanisms that may cause disorders and dysfunctions in bone growth must be taken into account when planning physical activities, in order to promote normal physiological growth patterns. The aim of this epidemiological investigation was to identify and analyze the relationships between sociodemographic, anthropometric and clinical aspects and O-S. A cross-sectional design was used, with a representative sample of 956 subjects: 474 (49.6%) males and 482 (50.4%) females. Age range varied between 12 and 15 years (mean = 13.7±1.04). We used a battery of tests, previously applied in a pilot study, which met the aims of the investigation. Descriptive statistics (frequency, mean and standard deviation) were used and the odds ratio was calculated from bivariate and multivariate logistic regression (p<0.05). A prevalence of 9.8% was found (n = 94 cases): 11% males and 8.3% females. Hierarchized multivariate analysis showed a significant association between regular physical activities (OR= 1.94; CI 95%, 1.22-3.10) and shortening of the rectus femoris muscle (OR= 7.15; CI 95%, 2.86-17.86). The results may serve as a basis for therapeutic and prophylactic measures, in addition to increasing our knowledge of this syndrome in Brazilian adolescents. This investigation used a multidisciplinary approach, involving elements of anatomy, nutrition, physical education and physical therapy to elucidate the object under study related to Osgood-Schlatter syndrome
