ABSTRACT

BACKGROUND: Low back pain and low limb disability are classical symptoms of patients with degenerative lumbar spondylolisthesis who are often treated with operative internal fixation.OBJECTIVE: To observe the improvement of low-back pain and low-limbs disability of patients with degenerative lumbar spondylolisthesis following the treatment with general spine system(GSS).DESIGN: Self control clinical study with patients as subjects.SETTING: Department of Orthopaedics, Peking Union Medical College Hospital.PARTICIPANTS: Sixteen patients with degenerative lumbar spondylolisthesis combined with lumbar stenosis, including 10 males and 6 females with the average age of 58.5 years(ranged from 42 to 72 years) received treatment in our hospital between September 2001 and December 2001. Patients with low back pain were found in 16 cases and low-limb claudication in 15cases; preoperative spondylolisthesis of grade I was observed in 10 cases and grade Ⅱ in 6 cases.METHODS: After receiving lumbar canal decompression by spinal process and GSS for restoring spondylolisthetic vertebra, as well as internalfixation and lumbar fusion operation, patients were followed up at postoperative week 2 and month 1,3,6,12,18,24 for assessing the low-back pain and low-limb disability and meanwhile preoperative spondylolisthesis and postoperative restroration were also assessed with X-ray.RESULTS: Totally 16 patients were followed up for an average of21.2appeared in 15 out of 16 patients, and intermittent claudication resumed to time of follow-up revealed that all spondylolisthetic vertebra were restored with restoring rate of 100% (16/16).CONCLUSION: GSS was proved of satisfactory therapeutic effect in patients with spondylolisthesis by obviously improving their low-back pain and intermittent claudication.
