ABSTRACT

Objective: In this study our main goal is to evaluate surgical outcome of transforaminal lumbar interbody fusion (TLIF) in lytic spondylolisthesis. Method: This experimental observational type study was carried out at Bangabandhu Sheikh Mujib Medical University and different private hospital in Dhaka from July, 2008 to June2020. A total number of 105 patients underwent TLIF for lytic spondylolisthesis were taken as a study sample. Results: During the study, out of 105 patients (40%) were 30 or below 30 years old, (26.6%) 31-40 years and (20%) 41-50 years. According to lytic spondylolisthesis level where 77% involved L4/L5 and 23% had L5/S1. Lower back pain (LBP) and leg pain VAS score showed relief of pain in all cases where during preoperative period VAS score of LBP and leg pain were 7.7±0.4 and 6.6+3.1 which were decreased into 2.5±0.6 and 2.0 ± 0.5 respectively and preoperative mean ODI score was 79.8± 4.4 which reduced into 11.3± 4.3 after 48 months of surgery. After surgery, 5% patient had superficial infection (Stitch infection), 2% patients had transient paresthesia along the distribution of the exiting root at the level of the surgery, 1% developed neurological deficit in the form of foot drop which gradually improved with Physiotherapy over 3 months and finally no neurological deficit. All patients achieved radiological fusion. 85% patients were rated as TLIF technique as a excellent or good, while 15% patients were rated as fair, no patient was rated as poor. Conclusion: Transforaminal lumbar interbody fusion is an easy, powerful and strong technique that achieves precise useful and radiological outcomes in Spondylolisthesis and it is secure and reliable in sufferers. Medical records proved that our sufferers did benefit considerably with this Transforaminal lumbar interbody fusion (TLIF) approach.
