Single Level Degenerative Lumbar Spondylolisthesis - Clinicoradiological Outcome of Treatment with Posterior Fusion with Instrumentation and Bone Graft (A Prospective Observational Study)

This single centre prospective observational study was aimed to investigate the clinicoradiological outcomes of posterior lumbar interbody fusion (PLIF) using autogenous bone graft and single segment instrumentation with pedicle screws in single level lumbar degenerative spondylolisthesis. The outcomes were measured using visual analogue scale (VAS), Oswestry disability index and Prolo Functional Economic Rating. Radiological outcome was measured using Brantigan fusion grading and modified Lee?s classification. All patients with age group greater than 50 years with single level degenerative lumbar spondylolisthesis of any grade and unresponsive to conservative management for 3 months were included in this study. The current study showed good symptomatic relief of symptoms and solid bony fusion in patients with single level degenerative spondylolisthesis using above mentioned procedure.
