Objective: The evaluation of hypertension for a patient before and after the start of upper cervical chiropractic care specifically with NUCCA (The National Upper Cervical Chiropractic Association) technique adjustments and its associated effects on blood pressure are examined. It is the aim of this paper to support the findings of the Pilot Study conducted by Bakris and Dickholtz, and to provi...

Background Atlantoaxial subluxation (AAS) is a serious complication of rheumatoid arthritis (RA) that can cause severe neck pain and neurological injury. Objectives This study aimed to identify prevalence associated factors AAS in Korean RA patients. Methods Data patients who visited an academic referral hospital Korea between September 2007 August 2020 were extracted. Patients <19 years old...

Background Although recent development of screw instrumentation techniques for rigid fixation of the atlantoaxial joint has increased surgical options, patients in whom screws of any type cannot be safely placed are sometimes encountered. We present a unique surgical technique for C1-2 transarticular screw placement utilizing a novel trajectory. Methods A 35-year-old male with a history of Do...

background: cervical spine sustains most of thevertebral column injuries, among other injuries, the disc degeneration and damage that lead to replacement of the damaged disc with cage or artificial disc. methods: the c4 to c6 vertebrae of a normal subject and a person with interbody fusion cage were 3d modelled and then analyzed using finite element method. the results of maximum stress and str...

We report five children who presented at the mean age of 1.5 years (1.1 to 1.9) with a progressive thoracolumbar kyphosis associated with segmental instability and subluxation of the spine at the level above an anteriorly-wedged hypoplastic vertebra at L1 or L2. The spinal deformity appeared to be developmental and not congenital in origin. The anterior wedging of the vertebra may have been sec...

High-flow vertebral arteriovenous fistulas (VAVF) are rare complications of cervical spine surgery and characterized by iatrogenic direct-communication of the extracranial vertebral artery (VA) to the surrounding venous plexuses. The authors describe two patients with VAVF presenting with ischemic presentation after C1 pedicle screw insertion for a treatment of C2 fracture and nontraumatic atla...

OBJECTIVE To develop a new method to describe cervical spine curvature and evaluate the potential for injury in the upper and lower cervical spine during simulated whiplash. DESIGN A method was developed to integrate the upper and lower cervical spine rotations and describe the spine curvature. BACKGROUND In vivo and in vitro whiplash simulations have documented the development of an S-shap...

Blunt cerebrovascular injury (BCVI) is known to be a potentially fatal complication of cervical spine injury (CSI). Methods for screening the appropriate population remain to be elucidated, especially in Japan. This retrospective study was conducted to predict the risk factors relevant to BCVIs. Among 92 patients with CSI transferred to our institution from April 2007 to March 2012, 40 patients...
