STUDY DESIGN A retrospective study. PURPOSE To comparatively investigated the rate of the adjacent segment degeneration and the clinical outcomes in patients with spondylolytic spondylolisthesis, spinal stenosis or degenerative spondylolisthesis. OVERVIEW OF LITERATURE There have been few studies reported on the adjacent segment degeneration following posterior lumbar interbody fusion(PLIF)...

AIM Evaluation of the efficacy of a dynamic stabilizing system for different indications using medium-term clinical and radiological parameters. METHODS Out of a total of 70 evaluated patients, 35 showed initial disc degeneration and disc herniation (group 1). In this group, additional nucleotomy was performed. Group 2 included 22 patients with initial osteochondrosis and facet joint osteoart...

A population-based database of 1263 consecutive patients who underwent microendoscopic diskectomy for single-level lumbar disk herniation between 2005 and 2010 was retrospectively analyzed to identify causes and characteristics of reoperation and associated risk factors. A total of 952 patients were eligible. Of these, 58 had revision spinal surgery. Causes and clinical parameters were retrospe...

BACKGROUND Degenerative lumbar scoliosis surgery can lead to development of adjacent segment degeneration (ASD) after lumbar or thoracolumbar fusion. Its incidence, risk factors, morbidity and correlation between radiological and clinical symptoms of ASD have no consensus. We evaluated the correlation between the occurrence of radiologic adjacent segment disease and certain imperative parameter...

The Coflex device may provide stability to the surgical segment in extension but does not restore stability in other motion. Recently, a modified version called the Coflex rivet has been developed. The effects of Coflex and Coflex rivet implantation on the adjacent segments are still not clear; therefore, the purpose of this study was to investigate the biomechanical differences between Coflex ...

We report two cases of adjacent segment degeneration in patients with idiopathic scoliosis who underwent surgical treatment with Harrington instrumentation in young age. Both patients developed a symptomatic degeneration of the disk immediately under the last stabilized level and were treated with decompression and stabilization. Clinical and radiological results are satisfactory at the follow-up.

OBJECTIVE The purpose of this study was to figure out the radiologic findings and risk factors related to adjacent segment degeneration (ASD) after anterior cervical discectomy and fusion (ACDF) using 3-year follow-up radiography, computed tomography (CT), and magnetic resonance image (MRI). METHODS A retrospective matched comparative study was performed for 64 patients who underwent single-l...
