A 39-year-old male pedestrian-hit-by-car was transferred to our institution with atlantooccipital dislocation (AOD) on outside computed tomography (CT) imaging. On arrival he had a rigid cervical collar in place. Given the reported AOD, we placed the patient flat, removed the cervical collar, and supported the head in neutral alignment with sandbags. Due to a technical issue uploading his prior imaging to our system, the patient underwent repeat CTs at our center. Subsequently, after the outside images were uploaded, we were able to compare his cervical spine CT images before and after removing his cervical collar. On comparison, we noted a substantial reduction in AOD after collar removal. We hope this serves as a reminder of this key step in managing a rare but deadly clinical entity and a small demonstration of the efficacy of this intervention.

Introduction: Traumatic patients with cervical spine motion restriction have difficulty with endotracheal intubation (ETI) due to the limitations of neck movement and mouth opening. Nevertheless, the removal of the cervical collar for ETI in a prehospital setting may lead to a deterioration in neurological outcomes. This study compares the success rate of ETI utilizing a video laryngoscope (VL) on a manikin, contrasting manual in-line stabilization (MILS) without a cervical hard collar against full immobilization.

As available treatments in obstructive sleep apnea are all associated with side-effects or adherence problems, there is a need for alternative treatment options. In this randomized, open, parallel-group intervention study, the effect of head extension by cervical collar was evaluated in patients with moderate obstructive sleep apnea. One-hundred patients with moderate obstructive sleep apnea (apneas and hypopneas per estimated hours asleep = respiratory events index: 15-30) were randomized to either lifestyle intervention, or cervical collar in combination with lifestyle intervention.

Cervical plexus block (CPB), like other types of regional anesthesia, represents an alternative anesthetic technique in those cases where the performance of general anesthesia (GA) carries an increased risk both for the patient and the outcome of the operative treatment. It has traditionally been used for years in carotid surgery as an alternative to GA, especially due to the possibility of superior monitoring - the awake patient. However, its effectiveness has been proven in other types of neck surgery, primarily in thyroid surgery, neck dissections, tracheostomy, central venous catheter insertion, clavicle surgery, etc.

Subconcussive impacts are very common in the sports world and can have many negative impacts on human function, including increased risk for cognitive decline and behavioral impairments such as chronic traumatic encephalopathy (CTE). The purpose of this article is to analyze the available literature on the effects of jugular vein compression applied by a cervical collar on cerebral structure and function in the setting of chronic impact exposure. This narrative review analyzed 17 articles on brain structure and function, published between 1992 and 2022.
