Correction and fixation surgery is indicated for degenerative scoliosis. Degenerative scoliosis is a condition where aging causes degeneration or displacement of the intervertebral discs and facet joints, leading to progressive deformity of the spine. As this deformity worsens, it can result in severe lower back pain that makes it difficult to stand, and may also lead to conditions such as gastroesophageal reflux disease (GERD).
