Spine
-
Controlled laboratory study. ⋯ These findings provide baseline information to enable the study of kinematic changes that occur in pathologic conditions of the spine and to determine how these might be affected following surgical intervention.
-
A unique case of a patient with diffuse idiopathic skeletal hyperostosis (DISH) associated with C1 posterior tubercle impingement resulting in spinal canal stenosis and cervical myelopathy. ⋯ This is the first report of unique C1 posterior tubercle impingement and myelopathy caused by DISH. We should keep it in mind that DISH can cause serious problems in the upper cervical spine even after 25 years of interval.
-
Analysis of magnetic resonance (MR) images of healthy volunteers. ⋯ MR imaging was successfully implemented as a noninvasive method for visualizing the synovial folds of the lateral atlantoaxial joints and quantifying their dimensions in healthy volunteers. The results of this study provide a basis for future studies investigating synovial fold pathology in patients with neck pain and headache.

Case Reports
Management of traumatic cervical spondyloptosis in a neurologically intact patient: case report.
Case report. ⋯ Fractures of the posterior elements functionally decompress the spinal canal and thereby allow for cervical traction to be safely implemented in patients with spondyloptosis. Safe restoration of anatomic alignment in the neurologically intact spondyloptotic patient is crucial to minimize the extent of surgical stabilization and create a long-term stable construct of the fracture dislocation.
