STUDY DESIGN A prospective, randomized, controlled study. PURPOSE The objective of this study was to evaluate the effectiveness of two techniques of skin preparation with povidone-iodine. OVERVIEW OF LITERATURE Preoperative skin preparation is important for preventing surgical site infection by reducing the bacteria in the surgical area. Povidone-iodine(More)
Meningioma is typically considered to be a benign tumor. Malignant transformation and metastasis of meningiomas are rare. Moreover, most meningiomas are intracranial, and there are few reports on intraspinal meningiomas. This report aimed to describe the clinical features and pathological findings of a case of malignant transformation and distant metastasis(More)
STUDY DESIGN Retrospective case series. PURPOSE To investigate the relationship between tumor location and clinical characteristics. OVERVIEW OF LITERATURE Hemangioblastoma is a rare disease that develops in the central nervous system. Magnetic resonance imaging (MRI) is useful to evaluate hemangioblastomas. Hemangioblastoma's location is designated as(More)
Peripheral nerve injury (PNI) triggers cellular and molecular changes in the spinal cord. However, little is known about how the polyunsaturated fatty acid-containing phosphatidylcholines (PUFA-PCs) are regulated in the spinal cord after PNI and the association of PUFA-PCs with the non-neuronal cells within in the central nervous system (CNS). In this(More)

We are extremely grateful for your interest in our manuscript. The report by Saunders et al. was very helpful. As you indicated, there are reports about hypoglossal nerve palsy (HNP) after soft tissue surgery of the(More)
A recurrent laryngeal nerve injury is known as a complication referring to an anterior cervical spine surgery. However, hypoglossal nerve injury is not well known yet. Herein we report a rare case of a 39-years-old male with a hypoglossal nerve injury after C3/4 osteophyte resection with Smith-Robinson approach. In this case there appeared difficulties of(More)
Objective When we perform surgical correction for spinal deformity with degenerative changes, nerve root impingement, traction , or nerve root injury could be occurred. Electromyo-graphic (EMG) monitoring provides a real-time measure of impending spinal nerve root injury during instrumented posterior lumbar fusion. However, the utility of intraopera-tive(More)
Sagittal alignment in Japanese elderly people-how much can we tolerate as normal sagittal vertical axis? Objectives Spinal sagittal alignment has been reported that it is highly associated with health related QOL in adult spinal deformity patients. Optimal sagittal alignment is critical for the efficient function of the musculoskeletal system. In Japan as(More)
Objectives Global sagittal spinal imbalance leads to compensatory pelvic retroversion and femoral flexion that is far from economical standing posture. Recent reports showed spinal instrumentation surgery provided remarkable restoration of spinal alignment and better health-related quality of life (HRQOL) by adult spinal deformity surgery. However, there is(More)
Gait analysis after corrective surgery for adult spinal deformity-good sagittal balance with improved lumber lordosis is important OBJECTIVE Patients with adult spinal deformity (ASD) commonly present with a forward trunk tilt when walking. We aimed to compare the trunk tilt while walking, before and after corrective surgery for ASD. We prospectively(More)
