Advance in evaluation of lumbar function after long fixation of degenerative scoliosis / 中华外科杂志

ABSTRACT

With the aging of the population, the incidence of degenerative lumbar scoliosis has increased year by year. Long-segment orthopedic fixation surgery is an important method for the treatment of severe degenerative lumbar scoliosis. Currently, the evaluation of postoperative results is mainly based on the degree of relief of postoperative clinical symptoms, as well as the improvement of imaging deformity and balance. The studies show that although surgery has high difficulty and risk, most patients can benefit from surgery. Besides, it is reported that long-segment fixation can alleviate the symptoms of pain and improve the quality of life. However, it also decreases the local activity of the lumbar spine, leading to stiffness of lumbar, which may affect the activities of daily living (ADL) partly. Lumbar Stiffness Disability Index (LSDI) is a scale for evaluating the impact of lumbar spine stiffness on ADL. The scale has certain limitations and needs to be applied to Chinese people on the basis of optimization. In this paper, the researches of lumbar spine function evaluation after degenerative lumbar scoliosis and long segmental orthopedic fixation and the clinical use of LSDI are briefly reviewed.
