Effects of Continuous Irrigation During Burring on Thermal Necrosis and Fusion Strength in a Rabbit Arthrodesis Model.

Background: High-speed burring used to prepare bony surfaces during arthrodesis procedures can increase heat generation that may impede healing and fusion. Irrigation during burring has the potential to improve early healing of burred bone surfaces and result in a stronger fusion mass. The purpose of this study was to determine the effects of continuous irrigation during burring on thermal necrosis and fusion strength in an in vivo arthrodesis animal model.

Acute spinal cord compression caused by vertebral hemangioma.

Background Context: The reported incidence of vertebral hemangioma within the spinal column is common. Most often these benign vascular tumors are incidental radiographic findings and do not cause neurological sequelae. Rarely, vertebral hemangiomas will cause compressive neurological symptoms, such as radiculopathy, myelopathy and paralysis.
