Changes in the curvature have not been reported in degenerative lumbar scoliosis (DLS) when the correction surgery was performed. The purpose of our study was to clarify the influence of the correction surgery of DLS. Twenty-one patients underwent corrective lumbar reconstruction surgery (1998–2003) only at the neurologically affected levels. The spinal curvature was retrospectively evaluated in these 21 patients with DLS using Cobb's methods. The mean preoperative Cobb's angle was 17.7° while the mean postoperative Cobb's angle was 6.1° (p < 0.0001) at 1 month after the surgery and 9.0° at the final follow-up. The correction rate was 65.2% at 1 month after the surgery and 50.2% at the final follow-up. Cobb's angle increased by 2.9°/43.4 months (mean, 0.80°/year) in these procedure. The surgical goals of DLS are the relief of neurological disorders and the cessation of the deterioration of spinal alignment. Strategies for DLS may include complete decompression, or correction of the spinal alignment in elderly patients with poor bone quality. Decompression and correction in the PLIF procedure only at neurologically affected levels may be one of the surgical procedures to challenge DLS.
