    We have reported a case of cervical spinal epidural hematoma of 61 year-old male, who had suffered from chronic renal failure and received hemodialysis therapy for fifteen years. He was referred to our clinic because of neck pain and weakness of extremities. He showed incomplete tetraplegic state and was bed-ridden. Myelogram, Isovist CT, and MRI suggested the presence of cervical epidural hematoma in the ventral side from C3 to C7. Twenty-nine hours after the onset of symptoms, a total laminectomy from C3 to C7 was performed. The source of the hematoma was not identified. The patient showed good recovery and became able to walk with a cane. He was discharged about two months after operation.
    Spinal epidural hematoma is a relatively rare condition which suddenly develops symptoms of spinal cord compression. Myelography, Isovist CT scan, and MRI have definitive diagnostic value. When this type of hematoma is suspected, these procedures should be performed as soon as possible for early diagnosis and appropriate surgical treatment.

    To understand mechanical characteristics of the vertebral body structure, a stress analysis of the lumbar spine was performed using the three-dimensional finite element method. The FEM model contained two adjacent vertebrae and the intervertebral disc, the structures of which were cortical bones, cancellous bones, annulus fibrosis, nucleus pulposus and ligament. Compulsorydisplacements (axial compression, flexion and extension) were applied to the model and the stresses were computed using the FEM program.
    The region of high stresses was found at the supero-anterior rim of the lower vertebra in compression; at the superior aspect of the upper vertebra and the supero-anterior rim of the lower vertebra in flexion; and at the superior aspect of the upper vertebra and the supero-anterior and pesterior rims of the lower vertebra in extension.
    Generally, high stresses in the sagital plane were located in the rims of vertebrae. This result may indicate the cause of osteophyte formation as a degenerative change.

  • Two Cases of Acute Traumatic Dislocation of the Peroneal Tendon

    We report two cases of acute traumatic dislocation of the peroneal tendon over the lateral malleolus, in whom we treated successfully with surgery. This injury is often misdiagnosed as ankle sparin because of pain and swelling, so provocative maneuver is essential to diagnosis. As redislocation frequently ensued with coservative treatment, we recommend surgical treatment.
