Causes and symptoms of sacral kyphosis

sacral kyphosisSacral kyphosis is the posteriorly convex sacral spine, which normally does not exceed 40 degrees. This part of the vertebral column is strong enough, so deformation in it are rare. Only against the background of trauma or congenital malformations of the sacral vertebrae appears deformation.

In newborns there is a total convexity of the spinal column, but it can be considered a physiological, as after a few months it disappears.

When forming the bulge there is no influence of factors such as stress muscle corset back. Over the area of the sacrum are gluteus muscles that perform more protective than the positioning (under them are major nerves). Consequently, hypertonicity of skeletal muscles of the posterior group of the thigh or the gluteal area has no significant effect on the formation of sacral spine.

This deviation may appear in young children with rickets (lack of calcium in the body). In this case, simultaneously with increased convexity of the lumbosacral (over 40 degrees) will be observed deformity of the lumbar, thoracic and cervical spine.
