BACKGROUND Skeletal and soft tissue damage are often associated with unilateral facet dislocations, which undoubtedly lead to instability of the spine and further increase difficulties in cervical reduction. This type of irreducible facet dislocation is usually accompanied with potential catastrophic consequences including neurological deficit and severe disability. Therefore, a consistent and ...

Observations of streamwise and crossflow instabilities on swept circular cylinders over a range of inclinations are presented. By considering sweep angles through the full range between the two extremes studied in the literature, we relate the streamwise vorticity of the unswept case (Kestin & Wood, J. Fluid Mech. 44) to the more aggressive crossflow instability at high sweep angles (Poll, J. F...

Cervical spine injury occurs in 5-10% of patients with traumatic brain injury (TBI) and the consequences of missing significant cervical injuries in unconscious blunt trauma patients are potentially devastating. An adequate cervical spine clearance protocol for unconscious patients must avoid missed injuries, but must also avoid unnecessary cervical immobilisation and the associated morbidity. ...

The cervical spine allows humans to perform complex motions including lateral bending, twisting, and flexion/extension. The anatomical structures of the cervical spine, such as the cervical discs, facet joints, and ligaments, are constantly under stress due to everyday activities. Sustained stress over time causes injury and degeneration in the structures of the cervical spine and the developme...

BACKGROUND AND PURPOSE The National Emergency X-Radiography Utilization Study Low-Risk Criteria were established to identify patients with a low probability of cervical spine injury in whom imaging of the cervical spine was unnecessary. The purpose of this study was to ascertain the number of unnecessary cervical spine CT studies on the basis of proper application of established clinical guidel...

spine or from direct pressure by synovial pannus [2]. We present a case of periodontoid rheumatoid pannus formation in which symptomatic relief and regression of pannus (imaged by MRI scanning) was achieved following a short course of infliximab therapy. A 65-yr-old female with a 33-yr history of rheumatoid arthritis presented with a 2 month history of severe intractable cervical spine (neck) p...

Cervical intervertebral disc herniation, or a slipped disc, is a common orthopedic disease in canines. The standard surgical treatment used to relieve the herniation is the ventral slot technique, wherein a small slot is created by drilling into a neighboring vertebral body and the intervertebral space to relieve the pressure. However, the defects created in the disc, vertebral body, and adjace...

This article reviews cervical laminoplasty. The origin of cervical laminoplasty dates back to cervical laminectomy performed in Japan ~50 years ago. To overcome poor surgical outcomes of cervical laminectomy, many Japanese orthopedic spine surgeons devoted their lives to developing better posterior decompression procedures for the cervical spine. Thanks to the development of a high-speed surgic...

Cervical spine anomalies can coexist with of the head and neck. The association cervical vertebrae (CVA) cleft lip palate (CLP) has been described as probably result a failure in normal embryological segmentation. most frequent congenital alterations CLP-related are vertebral fusion (VF) deficiency posterior arch (PAD). We report case an acute, non-traumatic onset paraparesis 14 years old girl ...

Background and Importance: The development of C5 root palsy is a well-known potential complication of cervical spine surgeries for the correction of cervical spondylotic myelopathy. It typically occurs unilaterally but on extremely rare occasions it might occur as a bilateral anomaly. The value of intraoperative neurophysiologic monitoring in detection of iatrogenic acute versus delayed onset C...
