Surgical experience on 27 cases of lumbar degenerative De novo scoliosis

Abstract

Objective To summarize the clinical features of lumbar degenerative scoliosis (LDS) and to explore the indications for surgery, selection of the surgical procedures, and the surgical efficacy in order to improve the clinical treatment level. Methods The clinical data on 27 patients who had undergone surgical treatment during the period of February 2005 to February 2009 were retrospectively analyzed. Results Of 27 patients, 6 received simple posterior decompression, the remaining 21 received resection of lamina of vertebral arch combined with spinal canal decompression, internal fixation of pedicle of vertebral arch, and articular process bone graft fusion or partial intervertebral bone graft fusion or transverse process fusion. The symptoms and signs were improved obviously in all the patients.Low back pain relieved in 77.8% of the patients, relieved in 92.5% of the patients, and the radiologic findings were improved in 74.1% of the patients. Conclusions For the patients with LDS who are surgical candidates, logical treatments should be established based on the specific symptoms and signs, the affected portion of the vertebral column, the stricture level of the spinal canal, the unstable state of lumbar vertebrae, the vertebral rotation degree, and the general physical condition, so that the long-term efficacy of surgery can be improved.
