INTRODUCTION: Circumferential fusion for lumbar low-grade isthmic spondylolisthesis (LGIS) supplies the perfect spinal stability and highest fusion charges. The goal of this research is to research outcomes of minimal invasive administration of LGIS and correlations between Intervertebral Foramen Floor (IFS) and different parameters.
METHODS: We retrospectively reviewed instances of 43 sufferers who underwent a minimally invasive circumferential fusion (Anterior lumbar interbody fusion adopted by percutaneous posterior pedicle screw fixation) for LGIS between January 2010 and December 2014 in our establishment. Inclusion standards had been one-level (L4-L5 or L5-S1) LGIS with low again and/or radicular ache. Pre- and postoperative radiographic evaluations had been carried out at 6, 12 and 24 months. Measurements (Share of anterior displacement, diploma of slip angle, peak of the intervertebral area and the IFS) had been obtained utilizing Surgimap®.
RESULTS: 19 sufferers (44.2%) had been males. Imply age was 43 years previous (19- 72years). The imply observe up of the collection was 18.Three months (Three-72months). Imply preoperative Visible Analogy Scale (VAS) for low again ache decreased from 70mm to 20mm and from 80mm to 10mm as to radicular ache. Anterior displacement was decreased from 18% to 7% (p<zero.01), diploma of slippage had been elevated from 9.eight° to 15.2° (p<zero.01), intervertebral peak was restored from four.4mm to eight.5mm (p<zero.01) and improve of the IFS was calculated 48.eight%.
CONCLUSION: One stage circumferential fixation for adults’ LGIS with out decompression, permits restoration of intervertebral peak allowing good discount of the slippage, an growing of the IFS and liberation of nerve roots.
