Bradycardia is the most common form of dysrhythmia developing after disruption of the sympathetic pathway by a spinal cord injury (SCI), and it can have fatal consequences, including cardiac arrest. Here, we report a case of cardiac arrest developing after cervical SCI attributable to sympathetic hypoactivity. A 26-year-old male pedestrian was admitted after a traffic accident. Radiologically, fractures were apparent at the C6-7 bilateral articular facets, and cord contusion with hemorrhage was evident at C4-7...

BACKGROUND: Traumatic C2-3 dislocation has been often described in the antero-posterior plane but is extremely rare in the lateral plane. Such dislocations have been described in thoraco-lumbar and C1-2. The need to study the imaging in multiple planes has been highlighted to plan proper realignment. METHODS: A young male presented with neck pain alone following a train accident. The imaging showed a fracture of C3 splaying it. The C2-3 showed lateral dislocation in the lateral plane with locked C2-3 facets on one side and C3-4 facets on the other...

We sought to assess the rate of CTA-diagnosed vertebral artery injury in patients with isolated transverse process fractures, with and without extension into the transverse foramen, in the blunt-trauma population served by our hospital. We queried our universities trauma registry between January 2009 and July 2014 for ICD-9 codes pertaining to cervical spine fractures. Of 330 patients identified, 45 patients had fractures limited to the transverse process and were selected for the study population. For each patient identified, demographics, injury mechanism, imaging reports, angiography findings, and treatments were recorded...

Althouygh Menkes disease has well-recognized neurologic, developmental, and cutaneous features, the initial presentation may resemble child abuse. We describe a 5-month-old boy with multiple fractures indicative of nonaccidental trauma who was ultimately diagnosed with Menkes disease. Copper deficiency leads to connective tissue abnormalities and may result in subdural hematomas, wormian bones, cervical spine defects, rib fractures, and spurring of the long bone metaphyses. Several of these findings, including fractures and subdural hematomas, may be misinterpreted as child abuse...

We report a case of successful intraoperative management using only low-volume regional anesthesia for the open surgical fixation of a traumatic clavicle fracture in a conscious 69-year-old man with severe chronic obstructive pulmonary disease. To avoid general anesthesia, we provided low-volume C5 and C6 nerve root blocks along with a superficial cervical plexus block using only 9 mL of anesthetic solution to avoid the often encountered complications of higher volume injections. Throughout the procedure, the patient remained comfortable and cooperative with stable hemodynamics and respiration...

Laryngeal fracture is a rare traumatic injury, potentially fatal, with an estimated incidence of 1 in 30,000 patients admitted to severe trauma centers. Because of the rarity of this injury, physician may be not aware of its existence, leading to a late diagnosis of this entity. We report a case of a 59-year-old woman admitted to the emergency room after a motorcycle accident with cervical trauma. The patient presented with dysphonia, hemoptysis, cervical subcutaneous emphysema, and increasing respiratory distress that led to the intubation of the patient...

BACKGROUND: Cervical spine injuries of variable severity are common among patients with an acute traumatic brain injury (TBI). We hypothesised that TBI patients with positive head computed tomography (CT) scans would have a significantly higher risk of having an associated cervical spine fracture compared to patients with negative head CT scans. METHOD: This widely generalisable retrospective sample was derived from 3,023 consecutive patients, who, due to an acute head injury (HI), underwent head CT at the Emergency Department of Tampere University Hospital (August 2010-July 2012)...

BACKGROUND: Traumatic odontoid fractures (TOFs) have been described as the most common injury affecting the C-spine in the elderly. Previous studies have identified degenerative changes and bone loss as important predisposing factors. However, their interaction and respective age-adjusted impact needs further clarification. METHODS: Retrospective analysis of 5303 patients (≥60 years) admitted to a level-I trauma center between 01/2008-01/2016 who underwent CT imaging of the C-spine...

Nonoperative management of fractures in the setting of diffuse idiopathic skeletal hyperostosis (DISH) or ankylosing spondylitis is often unsuccessful. The subaxial spine is a common site of hyperextension fractures in the setting of DISH. Fractures of the upper cervical spine are uncommon in DISH. We report, to our knowledge, the first case describing successful nonoperative management of a type 2 odontoid fracture in a patient with DISH. We discuss the patient's initial presentation, physical examination, imaging findings, and management...

PURPOSE OF THE STUDY In the management of dens axis fractures in patients older than 65 years of age the posterior approach is preferred due to osteoporosis and the risk of a failure of anterior osteosynthesis. The posterior approach, however, is associated with a higher incidence of complications. A combination of anterior transarticular fixation of C1/2 (ATS) with compression osteosynthesis of dens axis significantly increases the stability of osteosynthesis. MATERIAL AND METHODS In the period from 2009 to 2015 our hospital admitted 13 patients older than 65 years of age with a diagnosed type III dens axis fracture based on AO classification...

Traumatic high-grade spondylolisthesis in subaxial cervical spine is frequently associated with acute spinal cord injury and quadriparesis. There have been rare cases where such pathology demonstrates minimal to no neurological deficits. Assessment of the underlying biomechanics may provide insight into the mechanism of injury and associated neurological preservation. Patient 1 is a 63-year-old female presenting after a motor vehicle collision with significant right arm pain without neurological deficits. Imaging demonstrated C7/T1 spondyloptosis, associated with a locked facet on the left at C6/7 and a locked facet on the right at C7/T1, with a fracture of the left C7 pedicle and right C7 lamina...
