Study Design Retrospective clinical study. Objective To investigate the age-related surgical outcomes of laminoplasty. Methods One hundred patients who underwent an en bloc laminoplasty for cervical spondylotic myelopathy from 2004 to 2008 and were followed for at least 1 year were included in this study. The clinical outcomes were assessed with the(More)
The purpose of this retrospective study was to demonstrate the surgical outcomes of anterior spinal fusion (ASF) and posterior subtraction osteotomy (PSO) for osteoporotic vertebral collapse (OVC). Forty patients who underwent surgery for OVC at the thoracolumbar junction with neurological deficits were included in this study. ASF was primarily chosen for(More)
Study Design Case report. Objective To present two cases of neurogenic shock that occurred immediately following posterior lumbar interbody fusion (PLIF) and that appeared to have been caused by the vasovagal reflex after dural injury and incarceration of the cauda equina. Case Report We present two cases of neurogenic shock that occurred immediately(More)
A 74-year-old, right handed man, developed insidiously with levitation and clumsiness of the right upper limb. His right arm tended to levitate spontaneously, when he was examined. He could put the elevated arm down on command, while the arm resumed to antigravity posture when his attention was diverted. His right arm also exhibited unwilled elevation when(More)

On admission, he presented with vertical gaze paresis, axial rigidity, paratonia of extremities and gait disturbance. The attacks were preceded(More)
Pyroelectric sensors can detect changes of infrared rays. Usually , typical pyroelectric sensors are the digital output type, used for lighting switches and security systems. We can acquire, however, limited information from such digital on or off signals. We can also acquire a wealth of sensor data by using the analog type. Thus, this paper proposes a new(More)
