Study Design Single-center, retrospective study. Objective Suboptimal concentrations of vitamin D have been linked to hip and knee osteoarthritis in large, population-based cohort studies. We sought to examine the association of vitamin D levels with intervertebral disk disease. Methods From January 2010 through May 2011, 91 consecutive, eligible adult spine surgery patients who had undergone c...

The purpose of this report is to describe hyperextension dislocation of the cervical spine and to illustrate its often subtle radiographic features. An analysis of the lateral cervical spine radiographs in 20 patients with hyperextension dislocation of the cervical spine revealed the combination of diffuse prevertebral soft-tissue widening together with normally aligned cervical vertebrae in al...

Researchers have found a big interest in biological application of Fourier Transform Infrared (FTIR) spectroscopy. Evaluating many diseases, staging them and studying the chemical structures of different formed compounds in diseases are some of the research applications of FTIR. Cancer is also one of these diseases. Researchers are trying to set up FTIR methods to detect and diagnose cancer cel...

Study Design Retrospective case series. Objective To determine the rate of spinal incidental findings on magnetic resonance imaging (MRI) of the cervical, thoracic, and lumbar spine in the pediatric population. Methods We reviewed MRI imaging of the neuraxial spine in patients less than 18 years of age and documented abnormal spinal findings. We then reviewed the charts of these patients to det...

A 12-year-old, castrated male Maltese dog was presented due to a sudden onset of tetraparesis. A ventral, extradural compressive lesion at the C4-5 intervertebral disk space, most compatible with an intervertebral disk extrusion was found by radiography, myelography and computed tomography. The dog received ventral slot surgery for cervical intervertebral disk hernia. After the surgery, the dog...

Study Design Systematic review. Clinical Questions Among athletes who undergo surgery of the cervical spine, (1) What proportion return to play (RTP) after their cervical surgery? (2) Does the proportion of those cleared for RTP depend on the type of surgical procedure (artificial disk replacement, fusion, nonfusion foraminotomies/laminoplasties), number of levels (1, 2, or more levels), or typ...

Calcification of cervical intervertebral disks in childhood is a well-known entity [1-7], although the etiology remains unknown. Rarely, disk herniation also may be present and produce symptoms of cord compression . The disk herniation and calcification usually resolve with conservative therapy over a period of a few weeks to several months. We present an interesting case in which the diagnosis...
