The Japan Spine Research Society carried out a nationwide survey on complications of the spine, enrolling a total of 16 157 patients who had undergone spine surgery in 196 institutes in the 1-year period from January to December 2001. Diseases, surgical procedures, and complications were surveyed in detail. Forty-nine percent of patients were aged 60 years(More)
STUDY DESIGN A cross-sectional study was performed to elucidate the usefulness of a new clinical evaluation, and a prospective study was performed to detect hysterical paralysis using this evaluation method. OBJECTIVES To make a correct diagnosis of hysterical paralysis, a new clinical evaluation was developed. SUMMARY OF BACKGROUND DATA Hysterical(More)
We determined the incidence of and risk factors for clinical adjacent segment pathology (C-ASP) requiring additional surgeries among patients previously treated with one-segment lumbar decompression and fusion surgery. We retrospectively analysed 161 consecutive patients who underwent one-segment lumbar decompression and fusion surgery for L4 degenerative(More)
STUDY DESIGN A retrospective, consecutive case series. OBJECTIVE To determine the risk factors that have a statistically significant association with the need of tracheostomy in patients with cervical spinal cord injury (CSCI) at the acute stage. SUMMARY OF BACKGROUND DATA Respiratory complications remain a major cause of further morbidity and mortality(More)
Few studies have reported the characteristics of Modic changes (MCs) in the cervical spine in contrast to the lumbar spine. The purpose of this study was to identify the prevalence of MCs in the cervical spine and to elucidate the relationship of MCs with spinal canal stenosis and angular motion. 437 consecutive, symptomatic patients with neck pain with or(More)
STUDY DESIGN Retrospective outcome measurement study. OBJECTIVES The purpose of this study is to assess whether ossification of the posterior longitudinal ligament (OPLL) affects neurologic outcomes in patients with acute cervical spinal cord injury (SCI). SUMMARY OF BACKGROUND DATA There have so far been few reports examining the relationship between(More)
STUDY DESIGN A retrospective imaging and clinical study. OBJECTIVE To evaluate the extraneural soft-tissue damage and its clinical relevance in patients with traumatic cervical spinal cord injury (SCI) without major bone injury. SUMMARY OF BACKGROUND DATA To date, various kinds of cervical discoligamentous injuries have been demonstrated on magnetic(More)
Spinal cord injury (SCI) is a devastating disorder for which the identification of exacerbating factors is urgently needed. We demonstrate that transient hyperglycemia during acute SCI is a detrimental factor that impairs functional improvement in mice and human patients after acute SCI. Under hyperglycemic conditions, both in vivo and in vitro,(More)
STUDY DESIGN A retrospective, consecutive case series. OBJECTIVE To determine the risk factors that have a significant correlation with the severity of neurologic impairment in thoracolumbar and lumbar burst fractures. SUMMARY OF BACKGROUND DATA The correlation between spinal canal stenosis due to bony fragments and the severity of neurologic deficits(More)
The transplantation of neural stem/precursor cells (NSPCs) is a promising therapeutic strategy for many neurodegenerative disorders including spinal cord injury (SCI) because it provides for neural replacement or trophic support. This strategy is now being extended to the treatment of chronic SCI patients. However, understanding of biological properties of(More)
