Functional Outcome Of Spondylolisthesis Treated By Transforaminal Lumbar Interbody Fusion With Cage And Pedicular Screw Fixation – A Prospective Study
Journal Title: International Journal of Orthopaedics Traumatology & Surgical Sciences - Year 2016, Vol 2, Issue 2
Abstract
Background: Spondylolisthesis when symptomatic is treated by a variety of fusion techniques, the two commonest being posterior lumbar interbody fusion and transforaminal lumbar interbody fusion. The purpose of this study is to evaluate the functional outcome of spondylolisthesis treated by transforaminal lumbar interbody fusion with cage and pedicular screw fixation. Materials and methods: 30 patients of spondylolisthesis who underwent transforaminal lumbar interbody fusion with cage and pedicular screw fixation between September 2013 and June 2015 were included in this prospective study. The pre-operative and post-operative functional outcomes at the end of 1 year were assessed using Oswestry Disability Index (ODI) and p value calculated. Results: Out of the 30 patients included in the study, female-male ratio of 2:1 was observed. The mean age of the patients was 49.13 years (range 36-65 years). Twenty three patients (76.7%) had Grade I spondylolisthesis and 7 (23.3%) had Grade II spondylolisthesis. The mean operation time was 143.33 minutes (range 110-240 minutes) with a mean blood loss of 300 ml (range 150-500 ml). The average follow-up was 8.1 months (range 6-20 months). The mean ODI score pre-operatively was 31.46% (range 25-42%) and post-operatively 16.9% (range 10-28%). 3 patients developed intermediate complications with no long term effects. Excellent results were noted in 21 (70%) patients, good results in 8 (26.66%) and fair result in 1 (3.33%) patient. P value was found to be highly significant. Conclusion: Transforaminal lumbar interbody fusion with cage and pedicular screw fixation is an effective treatment option for spondylolisthesis with high fusion rates and minimal postoperative morbidity.
