Minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) is a relatively new surgical procedure that appears to minimize iatrogenic soft tissue and muscle injury. The authors describe a technique for MI-TLIF that permits the surgeon to reduce spondylolisthesis percutaneously. The results in 40 consecutive patients who underwent MI-TLIF for symptomatic spondylolisthesis utilizing this...

Background In the lumbar spine, degenerative spondylolisthesis or degenerative (not traumatic) slippage of one vertebral body over another is divided into 4 grades - grade I (25%), grade II (50%), grade III (75%), and grade IV (100%). Dynamic X-rays, magnetic resonance (MR), and computed tomography (CT) scans document the slip secondary to arthritic changes of the facet joint plus stenosis, oss...

Spondylolisthesis has always fascinated orthopaedist and others concerned with the treatment of low back disease. Spondylo means Vertebra and Olisthesis to slip or slide down a slippery path.In this orticle.the history of spondylolisthesis has been described,followed by the recent classification of different types of the condi­tion.There are Sdifferent types of spondylolisthesis­dysplastic,Isth...

ISBN 978-91-554-9340-0. The incidence of lumbar spinal stenosis (LSS) is steadily rising, mostly because of a noticeably older age structure. In Sweden, LSS surgery has increased continuously over the ...

BACKGROUND Comparatively little is known about the relation between the sagittal vertical axis and clinical outcome in cases of degenerative lumbar spondylolisthesis. The objective of this study was to determine whether lumbar sagittal balance affects clinical outcomes after posterior interbody fusion. This series suggests that consideration of sagittal balance during posterior interbody fusion...

Study Design Systematic review. Clinical Questions (1) Has the proportion and number of randomized controlled trials (RCTs) as an indicator of quality of evidence regarding lumbar fusion increased over the past 10 years? (2) Is there a difference in the proportion of RCTs among the four primary fusion diagnoses (degenerative disk disease, spondylolisthesis, deformity, and adjacent segment disea...

The purpose of this study was to investigate and determine whether there are differences in L5 pedicles morphology between isthmic degenerative L5–S1 spondylolisthesis. One hundred nineteen patients with spondylolisthesis 45 at were enrolled the IS group DS group, respectively, 164 lumbar disc herniation without spondylolysis or classified into normal (NL) group. A series pedicle parameters fif...

Introduction: Spondylolisthesis is a common disorder in lumabar vertebras and consist of more than 30% of lumbar fusions are diagnosed. Degenerative spondylolisthesis is seen more in women at level L4-L5 however isthmic spondylolisthesis is seen in men at level L5-S1. MRI is used commonly as first paraclinic test for evaluation of patients with back pain with or without radiculoapthy. It is use...

We reviewed 40 patients treated surgically for lumbar stenosis at an average time of 8.6 years after operation. In 32, total laminectomy had been performed and in eight bilateral laminotomy, both at one or more levels. Of the 16 patients with degenerative spondylolisthesis, ten had had a concomitant spinal fusion. Patients were assigned to one of four groups according to the amount of bone regr...

The purpose of this paper was to investigate the stand-alone lateral interbody fusion as a minimally invasive option for the treatment of low-grade degenerative spondylolisthesis with a minimum 24-month followup. Prospective nonrandomized observational single-center study. 52 consecutive patients (67.6 ± 10 y/o; 73.1% female; 27.4 ± 3.4 BMI) with single-level grade I/II single-level degenerativ...
