What Is Levoscoliosis?

Levoscoliosis is when the spine curves to the left, according to Spine-health. This type of curvature is common in the lower part of the spine, or the lumbar back, but uncommon in the middle of the back, or the thoracic spine.

Symptoms of any type of scoliosis include back pain, shoulders of unequal heights, shoulder blades in unequal positions and the head not centered the right way on the patient's body, notes North Shore-LIJ Orthopaedic Institute.

The causes of scoliosis include ruptured or degenerated vertebral disks, puberty and poor posture, reports North Shore-LIJ Orthopaedic Institute. Levoscoliosis in the thoracic back is sometimes caused by a spinal tumor. In most cases of scoliosis, however, the cause is unknown.
