Concomitant trauma of brain and upper cervical spine: lessons in injury patterns and outcomes

Purpose: The literature on concomitant traumatic brain injury (TBI) and traumatic spinal injury is sparse and a few, if any, studies focus on concomitant TBI and associated upper cervical injury. The objective of this study was to fill this gap and to define demographics, patterns of injury, and clinical data of this specific population. Methods: Records of patients admitted at a single trauma centre with the main diagnosis of TBI and concomitant C0-C1-C2 injury (upper cervical spine) were identified and reviewed. Demographics, clinical, and radiological variables were analyzed and compared to those of patients with TBI and: (i) C3-C7 injury (lower cervical spine); (ii) any other part of the spine other than C1-C2 injury (non-upper cervical); (iii) T1-L5 injury (thoracolumbar). Results: 1545 patients were admitted with TBI and an associated C1-C2 injury was found in 22 (1.4%). The mean age was 64 years, and 54.5% were females. Females had a higher rate of concomitant upper cervical injury (p = 0.046 vs non-upper cervical; p = 0.050 vs thoracolumbar). Patients with an upper cervical injury were significantly older (p = 0.034 vs lower cervical; p = 0.030 vs non-upper cervical). Patients older than 55 years old had higher odds of an upper cervical injury when compared to the other groups (OR = 2.75). The main mechanism of trauma was road accidents (RAs) (10/22; 45.5%) All pedestrian injuries occurred in the upper cervical injured group (p = 0.015). ICU length of stay was longer for patients with an upper cervical injury (p = 0.018). Four patients died in the upper cervical injury group (18.2%), and no death occurred in other comparator groups (p = 0.003). Conclusions: The rate of concomitant cranial and upper cervical spine injury was 1.4%. Risk factors were female gender, age ≥ 55, and pedestrians. RAs were the most common mechanism of injury. There was an association between the upper cervical injury group and longer ICU stay as well as higher mortality rates. Increased understanding of the pattern of concomitant craniospinal injury can help guide comprehensive diagnosis, avoid missed injuries, and appropriate treatment

Global Validation of the AO Spine Upper Cervical Injury Classification.

STUDY DESIGN Global Cross Sectional Survey. OBJECTIVE To determine the classification accuracy, interobserver reliability, and intraobserver reproducibility of the AO Spine Upper Cervical Injury Classification System based on an international group of AO Spine members. SUMMARY OF BACKGROUND DATA Previous upper cervical spine injury classifications have primarily been descriptive without incorporating a hierarchical injury progression within the classification system. Further, upper cervical spine injury classifications have focused on distinct anatomical segments within the upper cervical spine. The AO Spine Upper Cervical Injury Classification System incorporates all injuries of the upper cervical spine into a single classification system focused on a hierarchical progression from isolated bony injuries (type A) to fracture dislocations (type C). METHODS A total of 275 AO Spine members participated in a validation aimed at classifying 25 upper cervical spine injuries via computed tomography (CT) scans according to the AO Spine Upper Cervical Classification System. The validation occurred on two separate occasions, three weeks apart. Descriptive statistics for percent agreement with the gold-standard were calculated and Pearson's chi square test evaluated significance between validation groups. Kappa coefficients (ƙ) determined the interobserver reliability and intraobserver reproducibility. RESULTS The accuracy of AO Spine members to appropriately classify upper cervical spine injuries was 79.7% on assessment 1 (AS1) and 78.7% on assessment 2 (AS2). The overall intraobserver reproducibility was substantial (ƙ=0.70), while the overall interobserver reliability for AS1 and AS2 was substantial (ƙ=0.63 and ƙ=0.61, respectively). Injury location had higher interobserver reliability (AS1: ƙ = 0.85 and AS2: ƙ=0.83) than the injury type (AS1: ƙ=0.59 and AS2: 0.57) on both assessments. CONCLUSION The global validation of the AO Spine Upper Cervical Injury Classification System demonstrated substantial interobserver agreement and intraobserver reproducibility. These results support the universal applicability of the AO Spine Upper Cervical Injury Classification System

Effect of surgical experience and spine subspecialty on the reliability of the AO Spine Upper Cervical Injury Classification System.

OBJECTIVE The objective of this paper was to determine the interobserver reliability and intraobserver reproducibility of the AO Spine Upper Cervical Injury Classification System based on surgeon experience ( 20 years) and surgical subspecialty (orthopedic spine surgery, neurosurgery, and "other" surgery). METHODS A total of 11,601 assessments of upper cervical spine injuries were evaluated based on the AO Spine Upper Cervical Injury Classification System. Reliability and reproducibility scores were obtained twice, with a 3-week time interval. Descriptive statistics were utilized to examine the percentage of accurately classified injuries, and Pearson's chi-square or Fisher's exact test was used to screen for potentially relevant differences between study participants. Kappa coefficients (κ) determined the interobserver reliability and intraobserver reproducibility. RESULTS The intraobserver reproducibility was substantial for surgeon experience level ( 20 years: 0.70) and surgical subspecialty (orthopedic spine: 0.71 vs neurosurgery: 0.69 vs other: 0.68). Furthermore, the interobserver reliability was substantial for all surgical experience groups on assessment 1 ( 20 years: 0.62), and only surgeons with > 20 years of experience did not have substantial reliability on assessment 2 ( 20 years: 0.59). Orthopedic spine surgeons and neurosurgeons had substantial intraobserver reproducibility on both assessment 1 (0.64 vs 0.63) and assessment 2 (0.62 vs 0.63), while other surgeons had moderate reliability on assessment 1 (0.43) and fair reliability on assessment 2 (0.36). CONCLUSIONS The international reliability and reproducibility scores for the AO Spine Upper Cervical Injury Classification System demonstrated substantial intraobserver reproducibility and interobserver reliability regardless of surgical experience and spine subspecialty. These results support the global application of this classification system

Global Validation of the AO Spine Upper Cervical Injury Classification: Geographic Region Affects Reliability and Reproducibility.

STUDY DESIGN Global Survey. OBJECTIVE To determine the accuracy, interobserver reliability, and intraobserver reproducibility of the AO Spine Upper Cervical Injury Classification System based on surgeons' AO Spine region of practice (Africa, Asia, Central/South America, Europe, Middle East, and North America). METHODS A total of 275 AO Spine members assessed 25 upper cervical spine injuries and classified them according to the AO Spine Upper Cervical Injury Classification System. Reliability, reproducibility, and accuracy scores were obtained over two assessments administered at three-week intervals. Kappa coefficients (ƙ) determined the interobserver reliability and intraobserver reproducibility. RESULTS On both assessments, participants from Europe and North America had the highest classification accuracy, while participants from Africa and Central/South America had the lowest accuracy (P < .0001). Participants from Africa (assessment 1 (AS1):ƙ = .487; AS2:0.491), Central/South America (AS1:ƙ = .513; AS2:0.511), and the Middle East (AS1:0.591; AS2: .599) achieved moderate reliability, while participants from North America (AS1:ƙ = .673; AS2:0.648) and Europe (AS1:ƙ = .682; AS2:0.681) achieved substantial reliability. Asian participants obtained substantial reliability on AS1 (ƙ = .632), but moderate reliability on AS2 (ƙ = .566). Although there was a large effect size, the low number of participants in certain regions did not provide adequate certainty that AO regions affected the likelihood of participants having excellent reproducibility (P = .342). CONCLUSIONS The AO Spine Upper Cervical Injury Classification System can be applied with high accuracy, interobserver reliability, and intraobserver reproducibility. However, lower classification accuracy and reliability were found in regions of Africa and Central/South America, especially for severe atlas injuries (IIB and IIC) and atypical hangman's type fractures (IIIB injuries)

The Outcome of Subaxial Cervical Injury in Adult Patients Managed Surgically Through an Anterior Approach

Objectives:&nbsp;&nbsp;We determined the Outcome of subaxial cervical injury management in adults through anterior approach open reduction and fixation injury &lt; 72 hours. Material and Methods:&nbsp;&nbsp;A total of 71 patients declared to have a recent chronicle of traumatic cervical spine injury with a conventional diagnosis of subaxial injury by Magnetic Resonance Imaging (MRI) and X-Ray anteroposterior and lateral views. ASIA Impairment Scale was used for assessment and was done at the time of admission and after six months. Results: Mean age of the patients in our study was 38.54 ± 5.47 years. According to American Spinal Injury Association (ASIA) scale, improvement by two grades was seen in 18 cases and improvement by one – grade was observed in 48 cases. Mortality was seen in 5 cases, where 2 deaths were related to associated injury, one related to a complication of surgery and other 2 died due to aspiration complications. Out of 66 cases, the outcome was good in 49 (74.29%) and fair in 17 (25.76%). Conclusion:&nbsp;&nbsp;The study results revealed that Anterior Cervical Discectomy and Fusion (ACDF) is considered to be a better treatment choice for better anatomical stabilization of the spine with early reduction. Keywords:&nbsp;&nbsp;Subaxial cervical injury, anterior approach, ASIA (American Spinal Injury Association) scoring

Crashworthiness Investigation Of Cervical Spine Injuries Among Motorcyclists In Malaysia

This study looks at cervical spine injuries sustained by motorcyclists in motorcycle road crashes. There are hardly any studies on cervical spine injury of motorcyclists compared to studies on injuries sustained by car passenger during crash. The motorcycle rider is relatively more exposed to road hazards compared to a protected car passenger. They are therefore more prone to injury than those traveling in any other form of transport. The motorcycle is relatively less stable and accorded little protection to riders in road crashes compared to a four-wheeled vehicle. The cause of injury and injury mechanisms are more uncertain for a motorcyclist compared to a car driver. The objective of the present study is to correlate the motorcycle crash mode to the cervical injury sustained by motorcyclists in real-world scenes. The findings of the study unveiled ideas and information to safety engineers on designing a motorcycle restrain system as injury mechanisms were predetermined. Motorcyclists with cervical injuries admitted to the hospitals were selected for the present investigation. The types of injury sustained were acquired from the medical report. Information on the crash scene and crash mode was obtained from the police report and interview session arranged with the motorcyclist involved in the crash
