Background By and large vertebral osteoporotic fractures result, in increased kyphosis angle. This alteration could led to disturbance in the pulmonary function. Spinal deformity is associated with alterations in pulmonary function.
Objectives Our objective was to evaluate the pulmonary function in osteoporotic patients.
Methods Fifteen women with osteoporosis and vertebral fracture (G1), 20 women with osteoporosis without vertebral fracture (G2) and 20 mormal women (G3) were selected. All performed spirometry in the Viatrace-130 SL spirometer.
Results Our results showed that women with osteoporosis and vertebral fracture had increased kyphosis angle (median = 60 degrees), decreased forced vital capacity (G1 vs. G2, p = 0.020; G1 vs. G3, p = 0.039) and forced wxpiratory volume in the first second (FEV1)(G1 vs. G2, p = 0.008; G1 vs. G3, p = 0.014). When compared with women with no vertebral fracture and no osteoporosis there wasn`t difference. There was a negative correlation between thoracic kyphosis and the predicted value of expiratory forced volume in one second (p = 0.003). Since 55 degrees of thoracic kyphosis the pulmonary function had showed compromised (p = 0.021).
Conclusion We conclude that women with vertebral fracture have an increase of their kyphosis angle and a decrease of pulmonary function.
