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 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 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)
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)
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)
STUDY DESIGN A retrospective study. OBJECTIVE This retrospective investigation was conducted to determine efficacy and endurance of titanium mesh cage as a strut for interlaminar wiring by comparing with autologous iliac bone graft (AIBG). For patients with atlantoaxial instability (AAI), allograft bone was harvested on an interlaminar mesh cage and(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)
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)
BACKGROUND Common peroneal nerve palsy is a well-recognized complication following orthopedic procedure in and around the knee region. In neurosurgical practice, however, this kind of injury with regard to the patients' position is seldom reported. CASE DESCRIPTION We describe an immediately developed common peroneal nerve palsy in a 53-year-old slender(More)
