摘要Degenerative scoliosis ( DS ), known as de novo scoliosis developing after skeletal maturity without a previous history of spinal deformities, is associated with the asymmetric degenerative process of intervertebral discs and facet joints. It frequently involves the lumbar and thoracolumbar spine, and can give rise to symptoms of persistent low back pain, radicular pain and intermittent claudication as well as cosmetic concerns. In the presence of severe pain and progressive neurological deifcits, and when nonoperative treatment is ineffective, surgical management should be considered. A perfect classification scheme will help guide the operation decision-making, and while a uniifed standard for the DS classiifcation is lacking. Thus far, several classiifcation schemes have emerged to describe DS in previous literatures, including the Scoliosis Research Society ( SRS ) system, the Schwab system, the Simmons system, the Aebi system and the Coronal Imbalance system. The classiifcation schemes stated above are still not perfect now, but there is clinical signiifcance in each of them. Regarding the surgical management of DS, the primary aims are to relieve pain, normalize both sagittal balance and coronal plane deformity, restore normal function and improve the quality of life ( QOL ). However, due to the disparities in patients’neurogenic symptoms, general conditions and demands for QOL, the choice of treatment strategy is the key point of contention, especially aboutfusion segments. Although Silva and Lenke proposed the Lenke-Silva Treatment Levels I-VIto help guide the surgical planning, the question of fusion level selection still remains largely unsolved. All in all, comprehensive assessment before the surgery and selection of appropriate surgical approach play pivotal roles in improving the QOL of patients with DS.
