The aim of this study was to retrospectively evaluate the reliability and accuracy cervical pedicle screw (CPS) placement using an intraoperative, full-rotation, 3D image (O-arm)-based navigation system assess advantages disadvantages system.The involved 21 consecutive patients undergoing posterior stabilization surgery spine between April December 2009. patients, in whom 108 CPSs had been inserted, underwent based on intraoperative imaging O-arm system. Cervical positions were classified...
OBJECTIVE Corrective surgery for spinal deformities can lead to neurological complications. Several reports have described cord monitoring in deformity, but only a few included patients younger than 20 years with adolescent idiopathic scoliosis (AIS). The goal of this study was evaluate the characteristics cases intraoperative transcranial motor evoked potential (Tc-MEP) waveform deterioration during posterior corrective fusion AIS. METHODS A prospective database reviewed, comprising 68 AIS...
Thoracic ossification of the posterior longitudinal ligament (T-OPLL) is treated surgically with instrumented decompression and fusion. However, factors determining outcome this approach efficacy additional resection T-OPLL are unknown.To identify these in a prospective study at single institution.The subjects were 70 consecutive patients beak-type who underwent dekyphotic fusion had an average 4.8 years follow-up (minimum 2 years). Of patients, 4 (6%; group R) no improvement or aggravation,...
Background: The aim of this study was to demonstrate longitudinal radiographic changes at up five years in patients with pseudarthrosis after posterior lumbar interbody arthrodesis using carbon cages. Methods: From 2003 2006, prospective and CT (computed tomography) scan evaluations were made cages one or two levels 153 consecutive patients. At the one-year evaluation, seventeen early nineteen selected as subjects on basis more following characteristics: complete absence osseous bridging...
Study Design. Retrospective multicenter study. Objective. The goal of this study is to determine the characteristic imaging features spinal ependymoma in a review magnetic resonance (MRI) data for large series surgically proven cases. Summary Background Data. Common intramedullary neoplasms are mostly ependymomas and comprise 50% 60% neuroepithelial tumors adults. Preoperative prediction pathological diagnosis could enhance surgical planning explanation procedure patients. However, these...
Study Design Prospective clinical study. Objective Posterior decompression and fusion surgery for beak-type thoracic ossification of the posterior longitudinal ligament (T-OPLL) generally has a favorable outcome. However, some patients require additional postoperative severe paralysis, condition that is inadequately discussed in literature. The objective this study was to describe efficacy procedure we refer as "resection at an anterior site spinal cord from approach" (RASPA) severely...
Prospective study.Investigate factors associated with preoperative motor paresis, recovery, ambulatory status, and intraoperative neurophysiological monitoring (IONM) among patients no paresis (N group), complete recovery (CR (NCR group) in intramedullary spinal cavernous hemangioma to determine the optimal timing of surgery.The study evaluated 41 surgical cases our institute. Disease duration, tumor lesion, manual muscle testing (MMT), gait at onset, just before surgery, final follow-up...
We demonstrate fluorescence imaging with high intensity and depth resolution in which depth-induced spherical aberration (SA) caused by refractive-index mismatch between the medium biological sample is corrected. To reduce impact of SA, we incorporate a spatial light modulator into two-photon excitation microscope. Consequently, when fluorescent beads epoxy resin were observed this method SA correction, signal images was ∼27 times higher extension direction optical axes ∼6.5 shorter at ∼890...
Abstract BACKGROUND Surgery for thoracic ossification of the posterior longitudinal ligament (T-OPLL) is still challenging, and factors good surgical outcomes are unknown. OBJECTIVE To identify with prospective comparative study. METHODS Seventy-one consecutive patients who underwent decompression instrumented fusion were divided into or poor outcome groups based on ≥50% <50% recovery rates Japanese Orthopaedic Association score. Preoperative, intraoperative, postoperative findings...
Surgical site infections (SSIs) are one of the most serious complications in spine surgery. We investigated efficacy locally administered vancomycin (VCM) powder for prophylaxis on SSI after invasive retrospectively studied 174 consecutive patients who underwent In VCM group (n = 81), was wound before closing wound. Patients did not receive treatment were set as a control 93). compared patients' background, operation time, intraoperative blood loss, usage implants, presence deep SSI, and...
Study Design. Prospective cohort study. Objective. To investigate whether classification of increased signal intensity (ISI) on magnetic resonance imaging (MRI) spinal cord in patients with cervical ossification the posterior longitudinal ligament (C-OPLL) reflects severity myelopathy and surgical outcome. Summary Background Data. The relationship between ISI C-OPLL is unknown. Methods. 119 consecutive (91 men, 28 women) who underwent surgery were enrolled. T2-weighted MRI was performed...
Prospective clinical study.Many oral surgeons use platelet-rich plasma (PRP) for bone defects, but the efficacy of PRP spinal arthrodesis remains uncertain. The objective was to compare autologous local graft and with alone promotion bony union in posterolateral lumbar fusion (PLF) surgery, investigation safety over 10 years.A prospective study conducted 29 consecutive patients who underwent one-level PLF at L4/5 degenerative disease. Local on left (control) side right were grafted. area...
A prospective clinical study of factors related to myelopathy deterioration caused by thoracic because ossification the posterior longitudinal ligament (T-OPLL).The objective was investigate T-OPLL.Detailed analyses T-OPLL have not been reported.Twenty-two patients (group O) received observation therapy absence or mild myelopathy, which defined as walking unaided with support, and a Japanese Orthopedic Association (JOA) score above 7 points; 24 S) were treated decompression fusion...
Study Design. A prospective imaging study. Objective. The study investigated whether the classification of increased signal intensity (ISI) using magnetic resonance (MRI) reflects severity symptoms in patients with cervical spondylotic myelopathy (CSM). Summary Background Data. Although ISI on MRI CSM is observed, degree has not been examined. association between and surgical outcomes remains controversial. Methods. total 505 consecutive (311 males; 194 females) were enrolled. mean age was...
Study Design. Self-assembling peptide gel (SPG-178) provides new evidence for the role of a scaffold treatment spinal cord through induction neuroprotective factors. Objective. To verify reproducibility SPG-178 as after injury, we examine characteristics and protective effect on neural cells in vitro vivo . Summary Background Data. The central nervous system extracellular matrix may play maintenance neuronal network by inhibiting axonal growth suppressing formation additional inadequate...
A prospective comparison.The purpose of this study was to verify the clinical effectiveness 10-s grip and release (G&R) step quantitative tests for assessing severity cervical spondylotic myelopathy (CSM) compare age- sex-related differences in results between large cohorts CSM patients asymptomatic subjects.To determine CSM, objective reproducible means measuring patient disability are essential. No studies have evaluated test a series healthy subjects.Four hundred fifty-four 818 subjects...

A retrospective analysis of a prospective database.To compare preoperative symptoms, ambulatory ability, intraoperative spinal cord monitoring, and pathologic cell proliferation activity between intramedullary only plus extramedullary hemangioblastomas, with the goal determining optimal timing for surgery.The subjects were 28 patients (intramedullary in 23 cases [group I] 5 IE]) who underwent surgery hemangioblastoma. Preoperative ability on McCormick scale, findings using Ki67 compared...
We demonstrate that high-quality images of the deep regions a thick sample can be obtained from its surface by multi-focal multiphoton microscopy (MMM). The MMM system incorporates spatial light modulator to separate excitation beam into and modulate pre-distortion wavefront correct spherical aberration (SA) caused refractive index mismatch between immersion medium biological sample. When fluorescent beads in transparent epoxy resin were observed using four SA-corrected focal beams,...
