RESUMO Racional: Alto índice de massa corpórea, assim como a manutenção desta condição por longo período de tempo, são importantes fatores de risco para o desenvolvimento de osteoartrite. Objetivo: Determinar a prevalência de dor articular e osteoartrite em pacientes aguardando cirurgia bariátrica. Métodos: Pacientes obesos mórbidos responderam à escala e questionário (VAS e WOMAC) de dor e função. Radiografias dos quadris e joelhos foram avaliadas. Os desfechos primários foram dor articular referida nos questionários e o diagnóstico de osteoartrite feito através dos critérios clinicoradiológicos do Colégio Americano de Reumatologia. Resultados: Cento e quarenta e um pacientes foram entrevistados (85,1% mulheres) com idade média de 40 anos. A média do índice de massa corpórea foi de 46. Coluna lombar e joelhos foram as regiões mais comumente referidas com dor (77,9% e 73,2% respectivamente). A prevalência de osteoartrite dos joelhos foi de 63,1% e dos quadris foi de 40,8%. Idade, média da escala visual de dor e resultados do questionário de WOMAC foram maiores nos indivíduos com osteoartrite. Conclusão: Há prevalência de 90,1% de sintomas dolorosos nos pacientes obesos mórbidos encaminhados para cirurgia bariátrica. A osteoartrite dos joelhos foi de 63,1% e de quadris de 40,8%.

ABSTRACT Background: High body mass index, as well as maintaining this condition for a long period of time, are important risk factors for the development of osteoarthritis. Aim: To determine joint pain and osteoarthritis prevalence in patients referred to bariatric surgery. Methods: Morbidly obese patients referred to bariatric surgery responded to the visual analogue pain scale (VAS) and the WOMAC questionnaire. X-rays of the hips and knees were evaluated. The primary endpoints were self-reported joint pain and the diagnosis of osteoarthritis by clinical and radiological criteria of the American College of Rheumatology. Results: 141 patients were interviewed (85.1% women) with a mean age of 40 years. The mean body mass index was 46. The lumbar spine and knee joint were the most commonly reported as painful (77.9% and 73.2% respectively). Prevalence of knee osteoarthritis was 63.1% and hip osteoarthritis was 40.8%. Age, mean VAS and WOMAC scores were higher in the osteoarthritic individuals. Conclusion: There is prevalence of 90.1% of pain symptoms in morbidly obese patients referred to bariatric surgery. The prevalence of knee osteoarthritis was 63.1% and hip osteoarthritis was 40.8% in this sample.

Objective : To assess intra- and interobserver reproducibility of Sanders Classification System of calcaneal fractures among experienced and less experienced observers. Methods : Forty-six CT scans of intra-articular calcaneal fractures were reviewed. Four observers, two with ten years of experience in foot and ankle surgery and two third-year residents in Orthopedics and Traumatology classified the fractures on two separate occasions three weeks apart from each other. The intra and inter-observer reliability was analyzed using the Kappa index. Results : There was good intraobserver reliability for the two experienced observers and one less experienced observer (Kappa values 0.640, 0.632 and 0.629, respectively). The interobserver reliability was fair between the experienced observers (Kappa = 0.289) and moderate among the less experienced observers (Kappa = 0.527). Conclusions : The Sanders Classification System showed good intraobserver reliability, but interobserver reproducibility below the ideal level, both among experienced and less experienced observers.
