OBJECTIVE: To demonstrate the normal limits of Powers ratio and basion dens interval in
patients with disc herniations. METHODS: The MRI of patients were retrospectively …

DISCUSSION Dislocation at the craniocervical junction can result from extreme extension,"
lateral flexion," or extreme flexion." These actions may cause rupture of the craniocervical …

Although computed tomography has assumed an important role in the study of the spine, it
has significant limitations in the exploration of the cervico-occipital junction. With respect to …

Discussion Atlantooccipital dislocation has classically been described as invariably fatal (5).
However, reports of survival have accumulated with increasing frequency over the past …

BACKGROUND CONTEXT: Atlantooccipital dislocation (AOD) results in profound patient
morbidity and mortality and is difficult to accurately diagnose using current evaluation …

BACKGROUND AND PURPOSE: As the standard of care for the evaluation of the cervical
spine shifts from plain radiographs to multidetector row CT (MDCT), a re-examination of the …

In their paper," Preoperative Evaluation of Cervical Radiculopathy and Myelopathy by
Surface-Coil MR Imaging," Brown et al.[1] conclude that in many cases MR imaging can …

Thirty-six patients with pathology in the area of the craniocervical junction and the cervical
spine have been studied with Magnetic Resonance Imaging (MRI), using the Inversion …

Study Design The sensitivity of plain radiographs for diagnosing traumatic atlanto-occipital
dislocation and its association with craniocervical junction subarachnoid hemorrhage was …

Objectives: To evaluate the role of dynamic magnetic resonance imaging (MRI) in
craniovertebral junction (CVJ) abnormalities. Materials and Methods: Twenty-five patients …
