systems rehabilitation steps on the strain and temperature rise on apical and cervical root dentin regions. Twenty-one extracted human canine teeth had two strain gages attached to the distal root surface and two thermocouples attached to the mesial root surface (cervical and apical). The strain and temperature rise were recorded during the following procedures: root canal preparation, final ri...

OBJECTIVE The aim of this study was to compare the clinical and radiological outcomes associated with the use of hydroxyapatite (HA) spacer and allogeneic bone (AB) spacer in laminoplasty. METHODS From January 2006 to July 2014, 79 patients with cervical spondylotic myelopathy or ossification of the posterior longitudinal ligament underwent cervical laminoplasty. The radiologic parameters wer...

A 16-year-old boy vomited due to heatstroke during a soccer game but continued to train hard after the game. He was admitted to our hospital for chest discomfort three days later. Chest radiograph demonstrated pneumomediastinum, and computed tomography of the neck revealed emphysema within the spinal canal (Picture 1A) at cervical level 5 (Picture 1B, red arrows). Barium esophagography revealed...

__________________________________________________________________________________________ Purpose: Evaluation the rate of bacterial colonization of the genital tract among a large group of Polish women and the relationship between the types of bacteria from the cervical canal of pregnant women and preterm delivery. Materials and methods: 1084 pregnant women were taken swab from the cervical ca...

background & importance: disc herniation is defined as the prolapsed of material disc into the spinal canal. if the disc fragment is free in spinal canal, it is called sequestration disc fragment. occasionally, alteration in sequestration disc fragment makes the diagnosis of the disc herniation, challenging. case presentation: we reviewed a rare case of the cervical sequestrated disc herniation...

STUDY DESIGN Retrospective Cross-Sectional Study OBJECTIVE.: Identify the pathoanatomical features of the cervical spine associated with congenital stenosis SUMMARY OF BACKGROUND DATA.: Congenital cervical stenosis (CCS) describes a patient with a decreased spinal canal diameter at multiple levels of the cervical spine in the absence of degenerative changes. Despite recognition of CCS throughou...

BACKGROUND AND PURPOSE Upper cervical spinal canal dimension may have a role in abnormal CSF dynamics in patients with Chiari I malformation. We attempted to measure spinal canal tapering from anteroposterior spinal canal dimensions in patients with Chiari I. MATERIALS AND METHODS Twenty-one patients with Chiari I malformation, including 12 with syringomyelia and 7 patients with IS were ident...

We treated 12 patients with multilevel stenosis of the cervical canal after spondylosis or ossification of the posterior longitudinal ligament by an expansive open-door laminoplasty, stabilised by using an anchor system. The preoperative sagittal diameter of the canal was 9.8 mm(+/-2.2) which was increased to 16.1 mm(+/-2.9) after surgery. The mean expansion ratio of the canal was 64% (42 to 10...
