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)
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)
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)
STUDY DESIGN This was a retrospective observational study. OBJECTIVES The objectives were to describe the prognosis of upper extremity function following cervical spinal cord injury (CSCI), and to identify prognostic factors for functional recovery. SETTING Spinal Injuries Center, Japan. METHODS Sixty patients with C3-4 CSCI without major bone injury(More)
The purpose of the study was to evaluate the clinical relationship between cervical spinal canal stenosis (CSCS) and incidence of traumatic cervical spinal cord injury (CSCI) without major fracture or dislocation, and to discuss the clinical management of traumatic CSCI. Forty-seven patients with traumatic CSCI without major fracture or dislocation (30 out(More)
We report our initial results using a partial surface replacement for osteonecrosis of the femoral head. We believe the prosthesis has the most minimalist design that has been reported either in Europe or North America. The surgical technique, implant design, and instrumentation cause minor soft tissue disruption and require little bony resection. We report(More)
OBJECT Axial neck pain after C3-6 laminoplasty has been reported to be significantly lesser than that after C3-7 laminoplasty because of the preservation of the C-7 spinous process and the attachment of nuchal muscles such as the trapezius and rhomboideus minor, which are connected to the scapula. The C-6 spinous process is the second longest spinous(More)
STUDY DESIGN A retrospective, consecutive case series. OBJECTIVE To determine the risk factors for a tracheostomy in patients with a cervical spinal cord injury. SUMMARY AND BACKGROUND DATE Respiratory status cannot be stabilized in patients with a cervical spinal cord injury (CSCI) for various reasons, so a number of these patients require long-term(More)
