Orthopedic wires and pins are regularly used for the treatment of dislocations and bone fractures. Migration of these metallic fixation devices into the spinal canal is an uncommon complication. We present a 35-year-old man who underwent thoracic spinal canal migration of a Kirschner wire. The patient had undergone treatment of acromioclavicular joint dislocation with Kirschner wire fixation. T...

Contrast-enhanced computed tomography revealed spontaneous spinal epidural hematoma, which mimicked aortic dissection. A 90-year-old woman with a history of hypertension presented to the emergency department at night 3-h sudden neck-to-back pain, followed by loss sensory, motor, and bladder function. She had no prior injury or anticoagulant medication use. At admission, her vital signs were as ...

PURPOSE Mega-voltage cone-beam CT (MVCBCT) imaging can be used to monitor changes in neck flexion and calculate the true spinal cord dose during radiotherapy. To sum the dose over multiple fractions and compare with the planned dose requires deformable image registration. This study investigates the accuracy of deformable registration of the spine in kilovoltage CT (kVCT) to MVCBCT images for h...

pneumorrhachis (pr), which involves the entrapment of air or gas within the spinal canal, is a rare clinical entity. the pathogenesis and etiology of this uncommon entity vary and may present a diagnostic challenge. air in the spinal canal can be divided into primary and secondary pr, extra- or intradural pr and etiologically classified as iatrogenic, traumatic and non-traumatic. pr is typicall...

BACKGROUND Very severe osteoporotic vertebral compression fractures (vsOVCFs) are osteoporotic vertebral compression fractures with vertebral body collapse to less than one third of their original height. Few data are available about the use of percutaneous kyphoplasty (PKP) in treating vsOVCFs with spinal canal compromise. The aim of this study was to evaluate the safety and efficacy of percut...
