BACKGROUND Clinical adjacent-segment pathology (CASP) is an important problem after anterior cervical surgery. The purpose of this study was to predict prevalence of CASP and determine the possible risk factors for CASP after single-level anterior cervical discectomy and fusion surgery. MATERIAL AND METHODS We retrospectively reviewed a series of patients who underwent single-level cervical dis...

OBJECTIVE To study middle period curative effect of posterior lumbar intervertebral fusion (PLIF) and interspinous dynamic fixation (Wallis) in the treatment of L45 degenerative disease and its influence on adjacent segment degeneration. PATIENTS AND METHODS 66 patients with lumbar L45 degenerative diseases were selected for study. The patients were randomly divided into PLIF operation group ...

The cervical spine allows humans to perform complex motions including lateral bending, twisting, and flexion/extension. The anatomical structures of the cervical spine, such as the cervical discs, facet joints, and ligaments, are constantly under stress due to everyday activities. Sustained stress over time causes injury and degeneration in the structures of the cervical spine and the developme...

Klippel-Feil syndrome (KFS) is a complex congenital condition characterized by improper segmentation of cervical motion segments that could contribute to undesirable adjacent segment degeneration. KFS patients have a strong tendency to present with disease in the adjacent segments. When this condition is present, anterior decompression followed by total disc replacement can be performed safely ...

Surgeries for Lumbar Spinal Stenosis (LSS) aim at decompressing spinal nerves and relieving symptoms of radiculopathy or myelopathy. Frequently after surgery, stenosis may progress in adjacent spinal segments, but the etiology of adjacent segment degeneration is still unclear. It is hypothesized that surgical approaches for LSS may alter the normal biomechanics of adjacent segments, eventually ...

Abstract Background Facetectomy, an important procedure in the in–out and out–in techniques of transforaminal endoscopic lumbar discectomy (TELD), is related to deterioration postoperative biomechanical environment poor prognosis. Facetectomy may be avoided TELD with large annuloplasty, but iatrogenic injury annulus a high grade nucleotomy have been reported as risk factors influencing These al...

BACKGROUND/OBJECTIVE Internal disk disruption (IDD), an early event of lumbar disk degeneration, is the most common cause of low back pain. Since increased intradiskal pressure (IDP) is associated with symptoms and progression of disk degeneration, unloading a painful disk with an interspinous process device (IPD) is a rational treatment option. The goal of this study was to evaluate the effect...
