Résumé
STUDY DESIGN: The difference between the improvement after operation depending on the surgical method on patients with a spinal canal stenosis without instability were examined retrospectively. OBJECTIVES: To determine the difference between the improvement after surgery depending on the operative method on patients with spinal canal stenosis without an instability by using a retrospective study. SUMMARY AND LITERATURE REVIEW: There is a The clinical difference between simple decompression and fusion using instrument after decompression. MATERIAL AND METHODS: Sixty-six patients, who were diagnosed with pure spinal canal stenosis without instability and treated with surgery from October 2002 to April 2004 and were available for a follow up at least for 1 year were examined. There were 22 examples of decompression only and 22 examples of fusion using instruments. The change in postoperative pain was scaled using a visual analogue scale (VAS), and the functional disability in everyday life was clinically compared with the Korean ODI (KODI) and Lower Back Outcome Score for back pain (LBOS). RESULTS: 20 male and 24 females were examined, and the mean age was 61(45~76) years. the Million Visual Analogue Scale (MVAS) showed improvement in 28.3% of group A with decompression, and the everyday life disability scale using the Korean ODI and Lower back outcome score for back pain (LBOS) showed a improvement of 16.1% (KODI) and 18.4% (LBOS). Group B each showed 18.0% improvement using the VAS. The Korean ODI and Lower Back Outcome Score for back pain each improved by 18.0% (KODI) and 17.3% (LBOS) in two groups showing no statistically significant difference. CONCLUSION: There was little difference in the level of improvement in spinal canal stenosis patients without instability, regardless of ehether they had been treated with simple decompression or fusion using instrument after decompression.
