Decreased use of cervical spine clearance in blunt trauma: the implication of the injury mechanism and distracting injury

Blunt Assault: ‘Million Dollar Baby’

Contrasting reports exist in the literature regarding the management of patients with blunt assault to the head, neck, and face and more importantly for clearing the cervical spine. The purpose of our study was to determine the risk of cervical spine injuries after blunt assault to the head, neck, and face and its association with other injuries. We performed a retrospective case review of all blunt assault trauma admissions to the head, neck, and face at our Level I trauma center. We identified all patients who were assaulted with hands and feet and blunt instruments. A total of 3286 patients with blunt assault to the head, neck, and face were identified of whom 11 (0.003%) were found to have a cervical spine fracture or cervical spine subluxation. None of the patients had a cervical spinal cord injury. The 11 patients composed our study population with a mean age of 39 ± 7.8 years, 100 per cent were male, and the mean Injury Severity Score was 12 ± 7.9. Five (45%) patients required surgery for stabilization of the cervical spine. Mortality was reported in only one patient who had a C7 transverse process fracture. Cervical spine injury after blunt assault is rare but does occur and encompasses significant injuries requiring surgical intervention. However, these injuries are the result of direct blows to the cervical spine and we suggest that assaulted patients with no direct trauma to the neck do not require an exhaustive evaluation of the cervical spine.

The Diagnostic Value of Neuron-Specific Enolase in Children with Mild Blunt Trauma Requiring Cranial CT Scan

BACKGROUND

The present study was conducted to investigate the relationship between serum levels of enolase and pathological findings obtained from CT scans of the brain in children with mild blunt brain trauma and help with a more accurate diagnosis of brain injuries.

METHODS

The present observational study was conducted on children presenting with head traumas to the emergency department (ED) of Golestan Hospital in Ahvaz, Iran in 2016. A venous blood sample was immediately taken by the ward nurse from all the eligible patients within 6 hrs of the incident after obtaining their information, performing initial examinations and their initial stabilization. Laboratory serum levels and the corresponding interpretations of CT scans of the brain were collected, recorded and then evaluated and analyzed.

RESULTS

A total of 62 children with mild blunt brain trauma were included in the study. A significant difference was observed between the positive CT scan group (2.7±9.74 µg/L) and the negative group (4.23±1.33 µg/L) in terms of serum levels of enolase (P<0.0001). The area under the receiver operating characteristic (ROC) curve was 0.992 for serum levels of enolase in diagnosing brain lesions caused by mild head traumas. Moreover, with a cut-off point of 6.97 µg/L, brain lesions could be detected with a sensitivity of 93.55% and a specificity of 100%.

CONCLUSION

Serum levels of enolase were found to be higher in patients with brain injuries. This highly accurate diagnostic biomarker can be recommended for estimating the presence of brain lesions associated with mild head traumas in infants.

Cervical spine fractures in elderly patients with hip fracture after low-level fall: an opportunity to refine prehospital spinal immobilization guidelines?

BACKGROUND

Conventional prehospital spine-assessment approaches based on low index of suspicion and mechanism of injury (MOI) result in the liberal application of spinal immobilization in trauma patients. A painful distracting injury (DI), such as a suspected hip fracture, historically has been a sufficient condition for immobilization, even in an elderly patient who suffers a simple fall from standing and exhibits no other risk factors for spinal injury. Because the elderly are at increased risk of hip fracture from low-level falls, and are also particularly susceptible to the discomfort and morbidity associated with immobilization, the prevalence of cervical spine (c-spine) fracture in this patient population was examined.

METHODS

Hospital billing records were used to identify all cases of traumatic femur fracture in Minnesota (USA) in 2010-2011. Concurrent diagnosis and external cause codes were used to estimate the prevalence of c-spine fracture by age and MOI.

RESULTS

Among 1,394 patients with femur fracture, 23 (1.7%) had a c-spine fracture. When the MOI was a fall from standing or sitting height and the patient age was ≥ 65, the prevalence dropped to 0.4% (2/565). The prevalence was similar when the definition of hip fracture additionally included pelvis fractures (0.5%; 11/2,441). Eight of the 11 patients with c-spine fracture had diagnosis codes indicative of criteria other than the DI that likely would have resulted in immobilization (eg, head injury and compromised mental status).

CONCLUSIONS

C-spine fracture is extremely rare in elderly patients who sustain hip fracture as a result of a low-level fall, and appears to be accompanied frequently by other known predictors of spinal injury besides DI. More research is needed to determine whether conservative use of spinal immobilization may be warranted in elderly patients with hip fracture after low-level falls when the only criteria for immobilization is the distracting hip injury.
