Known causes of levoscoliosis include birth defects, arthritis, neuromuscular diseases, spine trauma and conditions such as osteoporosis, vertebral compression fractures and disk degeneration, according to North Shore-LIJ Orthopaedic Institute. Tumors are a rare cause of levoscoliosis. The majority of levoscoliosis cases have no known cause.
Scoliosis is a spinal disease that causes the spine to curve abnormally. Doctors use specific terms to describe the type of curvature of the spine present in scoliosis. Levoscoliosis is a type of scoliosis where the spine curves to the left by 10 degrees or more, particularly the lower part, explains North Shore-LIJ Orthopaedic Institute.
