Clinical Trial
Intraoperative Iso-C C-arm navigation in cervical spinal surgery: review of the first 52 cases.
Fifty-two study participants underwent cervical spine surgery using intraoperative Iso-C imaging with or without spinal navigation. ⋯ Iso-C intraoperative fluoroscopy is an accurate and rapid way to perform CT-quality image-guided navigation in cervical spinal surgery. In most cases, it obviates the need for postoperative imaging.

Prospective study. ⋯ The LWR had a positive correlation with the age, while the lipid LW had a positive correlation with BMD, even after controlling the age factor. The bone marrow lipid water content and metabolism acted as important roles in the internal environment of bone and influenced bone mineralization.

Retrospective clinical study. ⋯ Nonsurgical derived spinal hematomas are rare. In this series, most cases were spontaneous and located in the cervical or cervicothoracic region producing severe neurologic deficit and pain. Treatment should be surgical evacuation in the majority. As most hematomas are of great extension, alternating hemilaminectomy suffices for evacuation of extradural hematomas and supports the stability of the spinal segments. Outcome is highly dependent from initial neurologic status.

Case Reports
Fracture of the posterior margin of the lumbar spine: case report after an acute, unique, and severe trauma.
Case report. ⋯ An acute and severe spine trauma in a nonathlete adolescent with no previous history of lumbar pain can lead to posterior vertebra margin fracture. Neurologic deficiency may appear, and it can be directly related to the posterior displacement of bone fragment or to a compressive peridural hematoma. Radiographs and computed tomograph scans are used for diagnosis. Magnetic resonance imaging is accurate to visualize disc space and for the diagnosis of peridural hematoma. Treatment is surgical and consists of laminectomy, hematoma drainage, and excision of bone fragment. Discectomy and arthrodesis are to be considered in relation to age, magnetic resonance imaging findings, and type of bone lesions.

Dimensional measurement of cervical neural foramen at various positions, using reformatted computed tomography. ⋯ The present results are consistent with those of previous in vitro studies and may explain the clinical observation that cervical extension aggravates symptoms in patients with cervical radiculopathy and that flexion often relieves them.
