Background: Brown-Sequard syndrome (BSS) is a rare neurological condition resulting from a hemisection injury to or unilateral compression on the spinal cord. The most common causes of BSS that are amenable to be treated surgically can be divided into traumatic and non-traumatic injuries. Traumatic injuries are often reported as the main cause of BSS. However, non-traumatic injuries of the spin...

PURPOSE This study aimed to evaluate the usefulness of the needle aspiration alternative to open surgical drainage of children with suppurative cervical lymphadenitis requiring surgical drainage. METHODS From January 1998 to June 2008, we retrospectively reviewed 38 children treated with needle aspiration as management with suppurative cervical lymphadenitis instead of open surgical drainage....

Non-human primates are most suitable for generating cervical experimental models, and it is necessary to study the anatomy of spine in non-human when models. The purpose this was provide anatomical parameters spinal cord long-tailed macaques (Macaca fascicularis) as a basis spine-related studies. Cervical specimens from 8 male adult subjects were scanned by micro-computed tomography, an additio...

Morphometric investigations comparing normal and affected animals increase our understanding of spinal diseases in dogs. The aim of this study was to generate morphometric data for osseous-associated cervical spondylomyelopathy (CSM) in Great Danes (GDs). Magnetic resonance imaging (MRI) morphometric features of the cervical vertebral column of GDs with and without clinical signs of CSM were ch...

Klippel-Feil Syndrome (KFS) is a complex, congenital condition, originally described by Maurice Klippel and Andre Feil in 1912.1 It is characterized by congenital fusion of two or more cervical vertebrae. Because of the abnormal fusion process and altered spinal biomechanics with undue motion at the non-fused cervical segment, adjacent to fused segments, such individuals are predisposed to abno...

We sought to evaluate the distribution pattern of lymph node (LN) metastasis and to indentify preoperative and surgical pathologic factors, which predict positive lymph nodes in patients with cervical carcinoma treated with radical hysterectomy and lymph node dissection (RHND). 365 patients with cervical carcinoma treated by RHND at a single cancer center from 1995 to 2005 were included. 87 pat...

BACKGROUND Cervical spinal canal tapering may increase CSF velocities and pressures. One report suggests that the cervical spinal canal tapers more steeply in patients with Chiari I than in healthy subjects. The goal of this study was to test the conclusion by measuring spinal canal tapering in another cohort of patients. MATERIALS AND METHODS Consecutive patients with scoliosis and MR imagin...

Current neck injury criteria do not include limits for lateral bending combined with axial compression and this has been observed as a clinically relevant mechanism, particularly for rollover motor vehicle crashes. The primary objectives of this study were to evaluate the effects of lateral eccentricity (the perpendicular distance from the axial force to the centre of the spine) on peak loads, ...

BACKGROUND This study was designed to reevaluate the effectiveness of the Pavlov ratio in patients with cervical myelopathy. METHODS We studied 107 patients who underwent open door laminoplasty for the treatment of cervical myelopathy between the C3 to C7 levels. We determined the Pavlov ratio on preoperative and postoperative cervical spine lateral radiographs, the vertebral body-to-canal ra...

The aim of this study was to evaluate the influence of the flexion angle of files on the decentralization of root canals during instrumentation. Fifteen lower incisors were instrumented with Protaper Universal files and radiographed in two directions (mesiodistal and buccolingual) before and after instrumentation with a #15 K-file in position for evaluating the flexion angle of files. The speci...
