Dear Editor, We thank Dr. Abdel-Wanis and colleagues for their interest in our paper [1]. We do not mean at all to deny the value of Tokuhashi’s score [2] and Tomita’s score [3] as scoring systems to predict a prognosis of patients with metastatic spinal tumours. Our unpublished data showed a significant correlation between each score and survival period in(More)
BACKGROUND AND PURPOSE Although many studies have described clinical examination measures for the diagnosis of lumbar spinal instability, few of them have investigated the sensitivity and specificity of the measures that were used. The authors devised a passive lumbar extension (PLE) test for assessing lumbar spinal instability. The purpose of this study(More)
PURPOSE To determine characteristics responsible for improvement of low back pain after cervical laminoplasty for cervical spondylotic myelopathy. METHODS 18 men and 10 women aged 38 to 88 (mean, 71) years who had a low back pain visual analogue scale (VAS) score of 5 or more before cervical laminoplasty were included. In 12 patients the VAS score(More)
The internal fixing materials made from shape-memory alloys (SMAs) have recently been reported for long bone fracture. We present a new internal fixation technique using a cylindrical SMAs implant in a rat femoral fracture healing. The implant was designed in a shape to circumferentially fix the fractured bone using resilient SMA claws. To evaluate the(More)
Patients with breast or thyroid cancer with metastatic spinal tumours are expected to survive relatively longer than patients with other cancers with metastatic spinal tumours. The purpose of this study was to determine the clinical characteristics of long-term survivors of breast or thyroid cancer with metastatic spinal tumours. We studied the clinical(More)
BACKGROUND X-ray images of lumbar degenerative diseases often show not only claw osteophytes, but also pairs of osteophytes that form in a direction away from the adjacent disc. We have investigated the direction of the formation of anterior lumbar vertebral osteophytes across the lumbar vertebrae using a sufficient number of lumbar radiographs, because(More)
STUDY DESIGN A case of primary Ewing sarcoma of the lumbar spine is presented. OBJECTIVE To present and review a rare case of primary Ewing sarcoma of the lumbar spine that required differentiation from spinal infection. SUMMARY OF BACKGROUND DATA Primary Ewing sarcoma originating from the spinal column is very rare. Because Ewing sarcoma is one of the(More)
The purpose of the present study was to clarify changes in the psychological state of mothers of patients with idiopathic scoliosis, and to clarify relationships between the psychological states of the mothers and patients. The Maudsley personality inventory (MPI) was administered to 30 patients with idiopathic scoliosis who underwent surgery and their(More)
We devised a new leg reposition test, to assess gait and balance in patients with spinal diseases. This study included 344 patients who were scheduled to undergo spine surgery; 14 (4.1%) patients showed positive results. These 14 patients had worse gait status than leg reposition test-negative patients both preoperatively and postoperatively. The leg(More)
