BACKGROUND AND AIM OF THE STUDY: In this study, we aimed to investigate whether performing the immobilization at 20° instead of 0° changes cerebral oxygenation. MATERIALS AND METHODS: 33 volunteers were put in a hard cervical collar and backboard at 0° and immobilized for 30min. The cerebral oxygen saturations of the volunteers were measured at 1, 5, and 30min after the start of the procedure (Group 1). The volunteers were asked to return the day after the Group 1 procedure but at the same time...

Continuous positive airway pressure (CPAP) is currently the reference treatment for obstructive sleep apnea (OSA). The use of a face mask, although sometimes necessary, is often associated with increased airway obstruction due to mandibular retrusion. We report a small group of patients in whom addition of a cervical collar to a face mask allowed correction of obstructive events.

OBJECTIVES: Rigid cervical collars are known to increase intracranial pressure (ICP) in severe traumatic brain injury (TBI). Cerebral blood flow might decrease according to the Kellie Monroe doctrine. For this reason, the use of the collar in patients with severe TBI has been abandoned from several trauma protocols in the Netherlands. There is no evidence on the effect of a rigid collar on ICP in patients with mild or moderate TBI or indeed patients with no TBI. As a first step we tested the effect in healthy volunteers with normal ICPs and intact autoregulation of the brain...

A term infant born cyanotic failed multiple intubation attempts and tracheostomy placement. After esophageal intubation resulted in the ability to ventilate, he was presumed to have tracheal agenesis and distal bronchoesophageal fistula. He was transferred to our institution where he was diagnosed with Floyd Type II tracheal agenesis. He underwent staged tracheal reconstruction. He was discharged to home at 4 months of age with a tracheostomy collar, cervical spit fistula, and gastrostomy tube. He represents the sole survivor-to-discharge of tracheal agenesis in the United States...

OBJECTIVE: Current protocols for spine immobilization of the injured skier/snowboarder have not been scientifically validated. Observing changes in spine alignment during common rescue scenarios will help strengthen recommendations for rescue guidelines. METHODS: Twenty-eight healthy volunteers (18 men, 10 women) age 47±17 (range 20-73) (mean ±SD with range) underwent a mock rescue in which candidate patrollers completing an Outdoor Emergency Care course performed spine immobilization and back boarding in 3 scenarios: 1) Ski helmet on, no c-collar; 2) helmet on, with c-collar; and 3) helmet removed, with c-collar...

Atlanto-axial rotatory-subluxation (AARS) is the most common pediatric cervical spine injury. Patients usually present with contralateral rotation and inclination of the upper cervical spine after minor trauma, or associated with an infection of the upper respiratory tract. According to the authors, initial management of patients with acute and chronic AARS type I-II should comprise closed reduction and immobilization with a cervical collar or a Halo-Body-Jacket. Surgical options of open reduction or C1/2 fusion should be restricted to irreducible or recurrent subluxations...

STUDY DESIGN: Whiplash injury is a prevalent and often destructive injury of the cervical column, which can lead to serious neck pain. Many approaches have been suggested for the treatment of whiplash injury, including anti-inflammatory drugs, manipulation, supervised exercise, and cervical collars. Cervical collars are generally divided into two groups: soft and rigid collars. PURPOSE: The present study aimed to compare the effect of soft and rigid cervical collars on immobilizing head and neck motion...

OBJECTIVE Past studies have suggested correlations between abusive head trauma and concurrent cervical spine (c-spine) injury. Accordingly, c-spine MRI (cMRI) has been increasingly used in radiographic assessments. This study aimed to determine trends in cMRI use and treatment, and outcomes related to c-spine injury in children with nonaccidental trauma (NAT). METHODS A total of 503 patients with NAT who were treated between 2009 and 2014 at a single pediatric health care system were identified from a prospectively maintained database...

INTRODUCTION: Traumatic spinal subdural hematoma involving the retroclival region and upper cervical spine is a rare pathology. To our knowledge, there have only been two prior cases in an adult trauma patient. We describe a patient with pre-existing Chiari 1 malformation, who recently sustained a unilateral Type 1 OCF (occipital condyle fracture) with associated disruption of the tectorial membrane and transverse ligament, that returned with a retroclival subdural hematoma extending down to C7, causing spinal cord compression and symptomatic obstructive hydrocephalus...

RATIONALE: Solitary eosinophilic granuloma (EG), the most benign, common form of Langerhans cell histiocytosis, has a self-limiting process and is associated with a good prognosis. Immobilization is recommended as the first treatment strategy for solitary EG, although the treatment protocols are still controversial. Radiotherapy and surgery are secondary treatment choices. Lesions of the upper cervical spine react differently to treatment because of their specific anatomical and motor features...

BACKGROUND: External compression of the jugular veins is an effective method to increase intracranial blood volume and brain stiffness in rats and healthy volunteers. It has been reported that, on assuming an upright posture, cerebral venous drainage is distributed away from the internal jugular veins (IJVs) to the cervical venous plexus, causing complete collapse of the IJV. If so, it is not clear why external IJV compression would increase intracranial blood volume, but the latter is frequently observed in neurosurgery in the sitting position...

OBJECTIVE: Our objective in this study was to extend diaphragmatic pacing therapy to include paraplegic patients with high cervical spinal cord injuries between C3 and C5. INTRODUCTION: Diaphragmatic pacing has been used in patients experiencing ventilator-dependent respiratory failure due to spinal cord injury as a means to reduce or eliminate the need for mechanical ventilation. However, this technique relies on intact phrenic nerve function. Recently, phrenic nerve reconstruction with intercostal nerve grafting has expanded the indications for diaphragmatic pacing...

Atlanto-axial subluxation is a rare but potentially serious complication after otolaryngological procedures. We are describing a case of a 4-year-old child who developed atlanto-axial subluxation of the cervical spine after adenoidectomy. Our patient underwent adenoidectomy and, 18 days later, presented to the emergency department with her neck tilted to the left in a cock-robin position and complaining of neck pain persisting since the surgery. A multiplanar 3-dimensional computed tomography was obtained and confirmed the diagnosis of an atlanto-axial subluxation (Fielding type 3)...
