STUDY OF RESULTS OF TRANSFORAMINAL LUMBAR INTERBODY FUSION (TLIF) IN SPONDYLOLISTHESIS IN CIVIL HOSPITAL AHMEDABAD, GUJARAT,INDIA

Abstract

Introduction: Spondylolisthesis is a descriptive term derived from the Greek word spondylo (spine) and olisthesis (slip). spondylolisthesis is anterior translation of the cephalad vertebra relative to the adjacent caudal segment. For spondylolisthesis to occur there must be a failure of anatomic structures that normally resist this anteriorly directed force. These structures include the facets, annulus brosus, posterior bony arch, and pedicles. Radiological investigations are done for diagnosis and planning of treatment. Treatment includes conservative management and surgical management using different techniques. 1) To Estimate the clinical outcom Aim And Objective: e of patients who underwent Transforaminal lumbar interbody fusion (TLIF) in terms of symptoms and signs. This is a Prospecti Materials And Methods: ve Study, Sample size of 25 in which 18 were female and 7 males. After Institutional Ethics Committee approval, Study was conducted from September 2019 to December 2021 at a tertiary care Hospital. Consecutive patients with spondylolisthesis and planned for TLIF. Informed written consent was taken from all the patients. Observation And Results: Total 25 patients were included in the study out of that 7(28) % men and 18(72%) women. Majority of the study patients 16(64%) were belong to above 45 years age group. Preoperative minimum VAS scoring of back pain was 6 while the maximum was 8, with a mean of 6.8. The mean VAS scoring at 6 months follow up was 1.08 with a minimum of 0 while a maximum of 3, which is statistically signicant. In our study slip grade was reduced by 1 in 19 patients and by grade 2 in 5 patient and there was no improvement of grade in 1 patient. Out of 25 study patients, 1(4%) patient had supercial wound infection and only 1(4%) patient had complication of screw loosening. In our study Conclusion: 18(72%) patients were female while 7(28%) patients were male, with mean age of 47 years. showing that degenerative spondylolisthesis is common in females as compared to male, in age group more than 40 years. level of spondylolisthesis is L4-L5 while L5-S1 in 10(40%), indicating that L4-L5 is the more commonly involved as compared to L5-S1 due to sagittal inclination of the lower vertebra and relative stability of L5-S1 between the stout iliolumbar ligaments in the sacral ala and the L5 transverse process. Transforaminal lumbar interbody fusion is a safe and effective option to achieve circumferential fusion without sever complications. TLIF has been established as one of the most successful surgery for reducing pain and enhancing physical function in spondylolisthesis.
