简要总结
There is a high probability of mechanical complications in patients with degenerative lumbar scoliosis after long segment fixation and fusion, and there are few studies on distal borderline kyphosis deformity/failure. This study was designed to retrospectively analyze the patients with degenerative lumbar scoliosis (DLS) who underwent posterior selective decompression and long segment fixation and fusion surgery in the lumbar spine department of our hospital from April 2009 to May 2016. Patients' basic data, surgical data and preoperative, immediate postoperative and follow-up imaging data were collected to study the incidence of distal mechanical complications, risk factors and their relationship with clinical symptom scores in DLS patients undergoing posterior selective decompression and long segment fixation and fusion. It has guiding significance for clinical operation decision making.
