Spinal realignment surgery is performed when the gravity line of the vertebral column must be restored to normal or near-normal. This is to relieve stress on the muscles of posture in the back, hips, and knees. Usually this requires one or more osteotomies, a procedure in which a cut is made into the bone to correct alignment. Several forms of osteotomy exist, such as pedicle subtraction or Smith-Peterson. In addition, discectomy may be performed, as well as spinal fusion. Most patients achieve satisfactory results from their surgeries, but patients with past surgeries are at a higher risk of less optimal outcomes.
