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.

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.

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.

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.

Study of two cohorts with a differing severity of disease before and after treatment. ⋯ The German version of the cervical NASS patient questionnaire (NASS) is a valid instrument for patients with cervical spine health problems. As this instrument is also sensitive to change, it is recommended for use. Moreover, the present study gives evidence for the validity of the original cervical NASS questionnaire in English.
