The objective of this study was to compare efficacy of cervical surgery for myelopathy in patients > or = 70 and < or = 60 years of age. Forty patients > or = 70 years and 50 patients < or = 60 years of age with MRI and CT proven myelopathy were neurologically assessed using the JOA score. Three operative procedures were performed: anterior spinal fusion,(More)
Osteoporotic fracture in elderly populations is increasing worldwide, but there are few data on the incidence and outcome of osteoporotic fractures, including upper extremity and vertebral fracture, during a certain period in a defined geographic area. The purpose of this study was to determine the incidence of osteoporotic fractures in a particular area:(More)
BACKGROUND There have been no standardized surgical options for severe scoliotic curvatures ≥100°. Halo-gravity traction is a viable option for surgical treatment of severe scoliosis. The aim of this study was to evaluate the efficacy and safety of perioperative halo-gravity traction for scoliosis curves ≥100° with respect to radiographic outcomes and(More)
Hydrogen peroxide (H2O2), a reactive oxygen species, is an important signaling molecule for synaptic and neuronal activity in the central nervous system; it is produced excessively in brain ischemia and spinal cord injury. Although H2O2-mediated modulations of synaptic transmission have been reported in ventral horn (VH) neurons of the rat spinal cord, the(More)
STUDY DESIGN A retrospective comparative study. OBJECTIVE To compare the efficacy and safety of several different anchors in the apical levels of scoliotic curves > or = 100 degrees using radiographic outcomes and clinical complications. SUMMARY OF BACKGROUND DATA To the best of our knowledge, no reports have compared various anchors at the apical level(More)
STUDY DESIGN A retrospective study. OBJECTIVE To determine the clinical and imaging characteristics of postoperative C5 palsy after cervical open-door laminoplasty. SUMMARY OF BACKGROUND DATA Postoperative C5 palsy is a common complication of cervical laminoplasty, and although there are several hypotheses regarding its etiology, the pathogenesis and(More)
STUDY DESIGN A prospective study. OBJECTIVE To evaluate the effectiveness of prophylactic C4/C5 microforaminotomy with open-door laminoplasty for cervical myelopathy in preventing postoperative C5 palsy. SUMMARY OF BACKGROUND DATA Postoperative C5 palsy is a common complication of cervical laminoplasty. Although the etiology of C5 palsy and preventive(More)
BACKGROUND CONTEXT The use of nonsteroidal anti-inflammatory drugs (NSAIDs) had been implicated as a risk factor for nonunion in spinal fusion. Even with a number of animal and human studies suggesting NSAIDs either delay or inhibit spinal fusion rates, these drugs continue to be used because of demonstrated benefits. Diclofenac sodium is no exception. It(More)
In the basidiomycete Coprinus cinereus (C. cinereus), which shows a highly synchronous meiotic cell cycle, the meiotic prophase I cells demonstrate flap endonuclease-1 activity. To investigate its role during meiosis, we isolated a C. cinereus cDNA homolog of flap endonuclease-1 (CcFEN-1), 1377bp in length with the open reading frame (ORF) encoding a(More)
