Abstract

Introduction: Lumbar canal stenosis remains one of the most frequently encountered clinically important degenerative spinal disorders requiring operative treatment in the aging population. The simplest procedure is arthrodesis without instrumentation, but this has been found to be associated with a high rate of non-union. To study the short term clinical and functional outcome after posterior lumbar inter body fusion in cases of lumbar canal stenosis assessed by RODI score.
Methods: This is a prospective study of 30 cases of lumbar canal stenosis, who were treated operatively with decompression and posterior lumbar inter body fusion, which was carried out over a period of 6 months in a tertiary care centre. 16 women and 14 men were included in the study. Clinical and Functional assessment using RODI score was done again immediate post-operatively and at 1't, 3'd and 6th month post-operatively.
Result : In our study it was noted that most patients were in the age group of 41-50 years (36.7%) followed by 51-60 years (33.3%), wherein males were 14(46.7%) and females were 16 (53.3%). In this study it was found that there is significant improvement in RODI score for back pain over the 6 month follow-up. There is significant difference between mean improvement in RODI score with respect to number of levels involved (p=0.02).
Conclusion: RODI showed Posterior Lumbar interbody Fusion with interbody cage and local graft with posterior instrumentation gave significantly improved clinical and functional outcome by causing significant reduction in pain and patient disability.
