STUDY DESIGN: Cross-sectional study. OBJECTIVE: To determine the prevalence of KFS in asymptomatic patients in New York State. SUMMARY OF BACKGROUND DATA: Klippel-Feil syndrome (KFS) is characterized by congenitally fused cervical vertebrae and may not be diagnosed clinically because most patients do not have the classic triad of short neck, low posterior hairline, and decreased neck range of motion. KFS may be associated with abnormalities such as congenital scoliosis and deafness, and patients are at higher risk for neurologic injury following cervical spine trauma...

Background Context Odontoid process fractures are the most common injuries of the cervical spine in the elderly. Anterior screw stabilisation of type 2 odontoid process fractures improves survival and function in these patients but may be complicated by failure of fixation. Purpose To determine whether cement augmentation of a standard anterior screw provides biomechanically superior fixation of type II odontoid fractures in comparison to a non-cemented standard screw. Study design Twenty human cadaveric C2 vertebrae from elderly donors (mean age 83 years) were obtained...

INTRODUCTION: We report a rare case of cervical spine trauma through a cervical disc replacement and adjacent multilevel disc fusions. Cervical disc replacement (CDR) is a viable option for the surgical treatment of degenerative disc disease however long term follow up data regarding this operative technique is poor specifically relating to traumatic complications. We know of no previous reports of bilateral cervical pedicle fractures occurring adjacent to CDR and anterior cervical spine instrumentation...

BACKGROUND: Head-first impacts with an aligned cervical spine cause some of the most severe types of injuries due to the risk of fractures and associated spinal cord injury. Sports, such as football, mountain biking and horseback riding, contribute to the incidence of spinal cord injury but there is potential to reduce the risk of these injuries through a helmet-mounted device. METHODS: A novel device, the Pro-Neck-Tor mechanism, was incorporated into a commercial football helmet and tested in head-first impact experiments...

OBJECTIVE Acute spine trauma (AST) has a relatively low incidence, but it often results in substantial individual impairments and societal economic burden resulting from the associated disability. Given the key role of neurosurgeons in the decision-making regarding operative management of individuals with AST, the authors performed a systematic search with scoping synthesis of relevant literature to review current knowledge regarding the economic burden of AST. METHODS This systematic review with scoping synthesis included original articles reporting cost-effectiveness, cost-utility, cost-benefit, cost-minimization, cost-comparison, and economic analyses related to surgical management of AST, whereby AST is defined as trauma to the spine that may result in spinal cord injury with motor, sensory, and/or autonomic impairment...

The human cervical spine sustains compressive loading in automotive events and military operational activities, and the contact and noncontact loading are the two primary impact modes. Biomechanical and anatomical studies have shown differences between male and female cervical spines. Studies have been conducted to determine the human tolerance in terms of forces from postmortem human subject (PMHS) specimens from male and female spines; however, parametric risk curves specific to female spines are not available from contact loading to the head-neck complex under the axial mode...

BACKGROUND: Spinal injury is common in trauma suffered by both men and women. A lesser degree of involvement of females with spinal trauma, or at least, the different nature of such injuries, has been suggested. It has been proposed that behavioral and structural characteristics may explain the differential type and severity of spinal injuries in women. We carried out this study to find women-specific divergences in spinal traumatic lesions, including suspected mechanisms for their generation...

OBJECTIVE: The demographic change in the population leads to a rising number of patients presenting with fractures of the cervical spine, especially C-2, due to falls. With an increase of co-morbidities in these elder patients, the risk for intra- and postoperative complications is increased likewise. Thus, an alternative strategy instead of operative management of these fractures should be taken into account whenever possible. Conservative management of dens fractures in the elderly is still a subject of great controversy despite numerous studies on this topic...

REVIEW
Carolyn W Roberts, Jacek Toczyski, Jason R Kerrigan
While rollover crashes are rare, approximately one third of vehicle occupant fatalities occur in rollover crashes. Most severe-to-fatal injuries resulting from rollover crashes occur in the head or neck region, due to head and neck interaction with the roof during the crash. While many studies have used anthropomorphic test devices (ATDs) to predict head and neck injury, the biofidelity of ATDs in rollover has not been established. This study aims to build on previous research to compare the dynamic response and injuries sustained by four post mortem human surrogates (PMHS) to those predicted by six different ATDs in full-scale rollover crash tests...
