MOREIRA, Juan Javier Moreira; FUENTES, Andres Edgar Rodriguez  and  CORREA, Paulo Henrique De Castro. Radiological study of the angular value of thoracic kyphosis in adolescents. Coluna/Columna [online]. 2010, vol.9, n.4, pp.353-357. ISSN 1808-1851.

OBJECTIVE: to determine the difference of the thoracic kyphosis angular values using different levels (T2 a T5) as a terminal cranial vertebra. METHODS: sagittal radiographies of one hundred healthy adolescent volunteers, who study at Escola Industrial do Serviço Social da Indústria (SESI) in Ribeirão Preto SP), were evaluated the sagittal radiographies of one hundred health volunteers adolescent, that studies at Escola Industrial do SESI in Ribeirão Preto (SP), with parents consent. Ten adolescents were excluded because of flaws in the quality. The studied parameters were: the measurement of thoracic kyphosis by the Cobb method, using T2, T3, T4, T5 as a terminal proximal vertebra and T12 as a distal final vertebra. RESULTS: Ninety individuals (46 men and 44 women), aged from 13 to 15 (average of 14±6), were evaluated. The angular value of thoracic kyphosis in the different levels varied from 46º (T2 - T12) to 35º (T5 - T12) in men, and from 44º (T2- T12) to 30º (T5 - T12) in women. CONCLUSION: A constant difference of approximately 5º was observed when comparing the angular values of thoracic kyphosis using different levels (T2 - T5) as a terminal cranial vertebra.
