Abstract：Objective To explore the clinical curative effects of modified Jaslow technology on treatment of degenerative scoliosis.Methods A retrospective analysis was conducted on 14 patients with degenerative scoliosis underwent surgeries in the affiliated hospital of Xuzhou Medical College from March 2011 to June 2012. They received modified Jaslow technology, transforaminal interbody fusion and pedicle-screw internal fixation. The postoperative efficacy was evaluated by Japanese Orthopaedic Association(JOA) score for lower back pain, Oswestry disability index (ODI) and Cobb angle.Results These patients underwent successful surgeries. One patient with postoperative cerebrospinal fluid leakage received corresponding treatment and healed without retrograde intracranial infection. All patients were followed up for 12 to 16 months, with an average of 14 months. All patients were significantly improved in postoperative symptoms and signs. The last follow-up Cobb angle (3.35°±0.87°) and ODI(10.53±2.00) were significantly decreased compared with those before surgery(20.37°±5.57°, 39.42±8.34, t=10.99, t=15.06, all P values<0.01), and JOA score was significantly increased compared with that before surgery(25.00±1.22 vs 11.42±2.40, t=-24.72, P<0.01). After surgery for one year, the efficacy was evaluated according to the improvement rate of JOA score, and there were 13 patients with excellent efficacy and one patient with good efficacy. The anterioposterior and lateral X-ray lumbar radiographs were reviewed, without loosening, displacement and screw breakage in internal fixation. Review with X-ray test at neutral position and lateral position suggested that the all of the lumbar intervertebral space reached bony fusion.Conclusions Due to diverse ways of degenerative scoliosis surgery, the surgical plan needs to be selected depending to preoperative examination results. The posterior lumbar complete decompression, reset by modified Jaslow technology, pedicle-screw internal fixation and transforaminal interbody fusion have satisfactory clinical efficacy in treatment of scoliosis.
