Abstract：Objective To explore the clinical curative effects of improved modified Jaslow technology on treatment of lumbar stenosis.Methods The retrospective analysis was used in 23 lumbar stenosis patients who had surgical treatment from August 2011 to April 2012. Semi-laminectomy, transforaminal lumbar interbody fusion (TLIF) and transpedicular screw fixation were used with improved modified Jaslow technology to treat the patients. Preoperative and postoperative visual analogue scale (VAS) scores, Japanese Orthopaedic Association (JOA) scores and Oswestry disability index (ODI) were observed. Improvement rate of JOA was adopted for evaluation on clinical curative effects.Results Twenty-three cases were successfully completed the surgery. One case of patient was accompanied with cerebrospinal fluid leakage after the surgery. The patient was given the corresponding treatment and then recovered, and no retrograde intracranial infection occurred. Twenty-three cases were followed up with 12 to 23 months (average 18 months). The symptoms and signs in all patients were significantly improved. No screw was broken, and no internal fixation was loosened and shifted. VAS scores and ODI were significantly reduced at the last follow-up compared with the preoperative values, while JOA scores were obviously increased, and the differences were statistical significance (all P values <0.01). Review with X ray examination at neutral position and lateral position suggested that all of the lumbar intervertebral space reached bony fusion. The curative effect was evaluated according to the recovery rate of JOA scores at 1 year after the surgery. There were 21 cases of excellent results and 2 cases of good results, with the excellent and good rate of 100%.Coclusions There are various surgical methods for the treatment of lumbar stenosis. The operation scheme should be selected based on the patients′ preoperative evaluation results. Semi-laminectomy, TLIF and transpedicular screw fixation were used with improved modified Jaslow technology to treat the patients with lumbar spinal stenosis, and the clinical curative effects were satisfied.
