Study on Outcome Analysis of Transforaminal Interbody Fusion with Transpedicular Screws and Rods in Lumbar Spondylolisthesis and Spondylolysis

Abstract

Abstract Introduction The management of spondylolisthesis and spondylolysis is primarily conservative or surgical. There are various surgical procedures available for spondylolisthesis. Objective To evaluate the functional outcome and efficacy in patients undergoing transforaminal lumbar interbody fusion with transpedicular screws and rods in symptomatic lumbar spondylolisthesis and spondylolysis. Methods From 2017 to 2018, a prospective observational study was performed in a tertiary care hospital. The preoperative evaluation was performed both clinically and radiologically. Based on indications, transforaminal interbody fusion was performed. A total sample of 20 patients was included. The primary outcome variables were the visual analogue scale (VAS), the Oswestry Disability Index (ODI), slip percentage, and disc height at follow-up. For the statistical analysis, coGuide (BDSS CORP, Bangalore, Karnataka, India) was used. Results In 20 participants studied, the mean age was 48.25 ± 5.35 years old. Degenerative spondylolisthesis was seen in 60% of the participants. The majority (70%) of the patients had grade 2 slips. The mean difference of the VAS, the ODI, slip percentage, and disc height between the preoperative and postoperative periods was statistically significant (p < 0.001). The majority (70%) of the patients had no complications after the procedure. Conclusions Transforaminal interbody fusion with pedicle screws and rods is a safe, simple procedure and has less morbidity. This procedure also provides better functional outcomes and reduction in symptoms by maintaining the disc height and providing sagittal balance.
