A cross-sectional, multicenter study. ⋯ Factors associated with a higher risk vary between LBP and PGP. History of LBP, related or not to previous pregnancy or postpartum, LBP surgery, and anxiety were the factors more strongly associated with pregnancy-related LBP. When these variables are taken into account, obstetrical data from current or previous pregnancies and other variables do not show a significant association with LBP. Stage of pregnancy and depression were associated with PGP.

-
A retrospective study. ⋯ This technique is indicated for most patients with rigid post-traumatic kyphosis in the thoracolumbar spine and can yield satisfactory clinical results not only in terms of pain relief, kyphosis correction, vertebral height restoration, and spinal canal integrity preservation, but also in reducing the risk of excessive bleeding and spinal cord injury.
