The effects of phenolic-rich fraction (PRF) from Rhus verniciflua Stokes (Anacardiaceae) on the activities of cellular signaling molecules that mediate inflammatory responses in LPS-induced RAW 264.7 macrophages were investigated. At various concentrations of PRF significantly inhibited NO, PGE(2) and TNF-alpha production in LPS-induced RAW 264.7 macrophage(More)
OBJECTIVE There are numerous reports on the primary stabilizing effects of the different cervical cages for cervical radiculopathy. But, little is known about the subsidence which may be clinical problem postoperatively. The goal of this study is to evaluate subsidence of cage and investigate the correlation between radiologic subsidence and clinical(More)
In most spine surgeries, the physician directly performs the surgical operation with help of specially designed surgical tools along with off-line CT images and possibly with fluoroscopic images that provide the on-line status of current surgical operation for patient However, the surgical procedure generally requires accurate operational skills and(More)
The goal of this work is to develop a robot-assisted surgery system for spinal fusion, which is composed of a robot, a surgical planning system, and an optical tracking system. The system plays roles of assisting surgeon for inserting a pedicle screw in spinal fusion. Compared to pure navigation systems as well as conventional methods for spinal fusion, it(More)
Knowledge of the quantitative anatomy of the subaxial cervical vertebrae is essential to safely perform anterior cervical surgery and to ensure adequate decompression of neural structures. In spite of this, little has been published in the neurosurgical literature regarding the spatial relationship of the lower cervical vertebrae and the implications of(More)
OBJECTIVE Bilateral C1-2 transarticular screw fixation (TAF) with interspinous wiring has been the best treatment for atlantoaxial instability (AAI). However, several factors may disturb satisfactory placement of bilateral screws. This study evaluates the usefulness of unilateral TAF when bilateral TAF is not available. METHODS Between January 2003 and(More)
OBJECTIVE This multi-center clinical study was designed to determine the long-term results of patients who received a one-level posterior lumbar interbody fusion with expandable cage (Tyche(R) cage) for degenerative spinal diseases during the same period in each hospital. METHODS Fifty-seven patients with low back pain who had a one-level posterior lumbar(More)
OBJECTIVE Percutaneous endoscopic transforaminal lumbar discectomy (PETLD) can be performed by using foraminal, intervertebral, and suprapedicular routes. The aim of this study was to assess clinical results of three different routes of PETLD. METHODS One hundred eleven patients who underwent PETLD between January 2016 and October 2016 were included in(More)
Background Bertolotti syndrome is characterized by an abnormal enlargement of the transverse process of the most caudal lumbar vertebra. Most of the time it is asymptomatic, but when it is symptomatic it is associated with low back pain, radiating leg pain, or both. There is no consensus regarding management of this pathology. Open to minimal invasive(More)
BACKGROUND When considering various risk factors such as age, comorbidities, and complications related to the surgical procedure itself, open surgery in degenerative spinal stenosis is likely to cause more complications. Here, we report the surgical procedure and preliminary clinical results of percutaneous endoscopic stenosis lumbar decompression (PESLD)(More)
