OBJECTIVE: The authors discuss the existent correlation between augmented thoracic kyphosis in patients with juvenile Kyphosis or Scheuermann`s disease and hamstrings contraction. This correlation is marginally addressed by existing studies. METHODS: Between June and December 2003, 38 patients belonging to the Spine Group at the Department of Orthopaedics from Santa Casa de São Paulo, Brazil, were analyzed. Among them, 26 (68.4%) were males and 12 (81.6%) were females. The youngest age was 10 and the oldest one was 20 years, with an average of 15.36. Twenty (52.6%) patients presented with Scheuermann´s disease and 18 (47.4%) with juvenile Kyphosis. RESULTS: From all 38 patients under study, 32 (84.2%) presented hamstring contracture, which was statistically significant (p<0.001). 85% of patients presenting only Scheuermann`s disease and 83.3% of patients with only juvenile Kyphosis had contracture. Conclusion: There was no statistically significant difference between contraction percentage in Scheuermann`s disease patients versus juvenile Kyphosis patients (p=0.61).
