Background Tumor-related white matter change is detected at late stages with magnetic resonance imaging (MRI), when mass effect or prominent edema present.We analyzed if diffusion tensor (DTI) earlier than conventional MRI. MethodsTwenty-six patients gliomas (World Health Organization grade II, 5; III, 12; and IV, 9) within 2 cm from the posterior limb of internal capsule (IC) were studied.Fifteen normal adults enrolled as controls.Fluid attenuation inversion recovery MRI showed a high...
Abstract MRI is the primary diagnostic modality for spinal cord tumors. However, its validity has never been vigorously scrutinized in daily routine clinical practice, where tissue diagnosis usually not a single one but multiple ones with several differential diagnoses. Here, we aimed to assess of terms predicting pathology and location tumor settings. We analyzed 820 patients tumors, who have pathological operation record which were confirmed. modified traditional measures based upon set...
Lumbar spinal stenosis (LSS) and sagittal imbalance are relatively common in elderly patients. Although the goals of surgery include both functional radiological improvements, criteria correction may be too strict for If main symptom patients is not forward-stooping but neurogenic claudication or pain, lumbar decompression without adding fusion procedure a surgical option. We performed cost-utility analysis between those Elderly (age > 60 years) who underwent 1-2 levels (F-group, n = 31)...
OBJECTIVE Most studies on the enhanced recovery after surgery (ERAS) protocol in spine have focused patients with degenerative spinal diseases (DSDs), resulting a lack of evidence for comprehensive ERAS applicable to primary tumors (PSTs) and other diseases. The authors had developed gradually adopted components all surgical procedures from 2003 2011, then current was fully implemented 2012. This study aimed evaluate impact applicability across compare outcomes between PST DSD groups....
Occasionally, unexpected neurological deficits occur after lumbar spinal surgery. We report a case of monoparesis decompressive A 63-year-old man, who had undergone decompression L4-5 for stenosis 4 days previously in the other hospital, visted emergency department with progressive weakness left leg and hypoesthesia below sensory level T7 on right side. He been cured lung cancer chemotherapy radiation therapy 10 years previously, but detailed information radiotherapy was not available. Whole...
A fibrin sealant is commonly applied after closure of an incidental or intended durotomy to reduce the complications associated with leakage cerebrospinal fluid. Routine usage might not be essential durotomy, which has clear cut-margins. We investigated efficacy sealants for primary intradural spinal cord tumor surgery.A retrospective review was performed 231 consecutive surgically treated patients tumors without extradural extension. Fibrin were used 47 (group I: age, 51.57±16.75 years) and...
Objective Posterior full-endoscopic cervical foraminotomy (PECF) is one of minimally invasive surgical techniques for radiculopathy. Because minimal disruption posterior structures, such as facet joint, kinematics was changed. However, a larger resection joint required foraminal stenosis (FS) than disc herniation (DH). The objective to compare the between patients with FS and DH after PECF. Methods Consecutive 52 (DH, 34 vs. FS, 18) who underwent PECF single-level radiculopathy were...
Total en bloc spondylectomy (TES) is a curative surgical method for spinal tumors. After resecting the 3 columns, reconstruction of paramount importance. We present cases mechanical failure and suggest strategies salvage surgery.The medical records 19 patients who underwent TES (9 primary tumors 10 metastatic tumors) were retrospectively reviewed. Previously reported techniques used, extent was 1 level in 16 2 levels patients. A titanium-based mesh-type interbody spacer filled with...
This study investigates the effect of dynamic changes in monitor height and tilt on neck pain posture computer users. Using a wearable device, we aim to compare spine angle between static monitors. A tracking system using Inertial Measurement Unit (IMU) was proposed, accuracy validated. Eight office workers participated for five hours over two days, each day used either or that changed every 30 min. The angles C0, C7, L1, S1 endplates were estimated proposed system. Changes with time...
Objective Cervical expansive laminoplasty is an effective surgical method to address multilevel cervical spinal stenosis. During surgery, the spinous processes of C2 and C7 are usually preserved keep insertion points musculature nuchal ligament intact. In this regard, dome-like laminectomy (undercutting lamina) instead performed on in selected cases. However, resection lamina can weaken lamina, stress fractures may occur, but complication has not been characterized literature. The objective...
Abstract Objective: Enteral nimodipine is the most evidence-based and widely used drug for treatment of delayed cerebral ischemia (DCI) known to have various neuroprotective functions. However, mechanism still remains unclear effects remain ambiguous. Herein, we studied effect enteral on endothelial apoptosis after subarachnoid hemorrhage (SAH). Method: SAH was experimentally introduced in white rabbits (n=42) that were grouped: (group N, n=14); a control received normal saline S, n=13);...
