The AO-Magerl, thoracolumbar system, and Subaxial Cervical Spine Injury Classification systems are all well known, but did not achieve universal international adoption. Tasked with creating a new classification for spine trauma, the AOSpine Knowledge Forum Trauma group has developed a unified classification system for trauma to the entire spinal column. Bilateral Injures Disclaimer: 1. Evaluation of the reliability and validity of the newer AOSpine subaxial cervical injury classification (C-3 to C-7) Otávio Turolo Da Silva, Marcelo Ferreira Sabba, Henrique Igor Gomes Lira, Enrico Ghizoni, Helder Tedeschi, Alpesh A. Patel , Andrei Fernandes Joaquim * • The Subaxial Injury Classification (SLIC) and severity scale is recommended as a classification system for spinal cord injury. Traumatic cervical spine injuries are a relatively common sequelae of blunt trauma. In 2012, the AOSpine Knowledge Forum Trauma committee revised the classification scheme and created a single classification system for spinal column trauma. The classification system describes injuries based on four criteria: morphology of the injury facet injury neurologic status case-specific modifiers Each criterion is described below. After enrollment, patients . The AO Spine Thoracolumbar and Subaxial Injury Classification systems are the result of a systematic assessment and revision of the Magerl classification. In this regard, there is an obvious need for a spinal injury classification that optimizes the choice of a treatment approach and predicts treatment outcomes. The AO Spine Subaxial Cervical Spine Injury Classification System (AO Spine SCICS) utilizes a clear morphologic framework to guide and standardize patient management based on four major criteria . AO Spine has published four injury classification systems: AO Spine: upper cervical classification system. Introduction Injury classification is important for communication between providers, patient care as well as for research purposes. In this regard, there is an obvious need for a spinal injury classification that optimizes the choice of a treatment approach and predicts treatment outcomes. 2.

AOSpine thoracolumbar spine injury classification system. The AOSpine subaxial cervical spine injury classification system was recently described. Anatomic variations of the VA can increase the risk of iatrogenic lacerations. Methods A single-center prospective cohort study was conducted that included patients with traumatic CSCIs (C3-C7) between February 2015 and October 2016. The AO Spine classification of subaxial injuries aims to simplify and universalise the classification of subaxial cervical spine fractures and improve interobserver and intraobserver reliability.. Usage. Considering the similarities between the AOSpine subaxial cervical spine injury classification system and the new AO Spine thoraco-lumbar spine injury classification system, and taking into account that the latter has been positively tested both by its developers and by independent groups in terms of agreement [7, 8], we might expect superior . The AOSpine class was A4 in 8, B2 in 5, B2A4 in 16, B3 in 19, and C in 44 patients. A subaxial cervical spine injury classification system was developed using a consensus process among clinical experts. AIS grade was A in 48, B in 25, and C in 19 patients. AO Spine classification of sacral injuries. 1-6 While the entire cervical spine is prone to injury, the subaxial cervical spine, which extends from C3 to C7, accounts for approximately half of these injuries. The objective of this study was to use the AOSCIS and compare it to the widely used Allen classification (AC) based on mechanics for subaxial cervical spine injury. The AOSpine subaxial cervical spine injury classification system demonstrated substantial reliability in this initial assessment, and could be a valuable tool for communication, patient care and for research purposes. Tension Band Injuries Type C. Translation Injuries Type F. Facet Injuries Type A. The AOSpine Subaxial Cervical Spine Injury Classification System was recently developed by international academics as an all-encompassing and universally accepted means of classifying cervical spine injuries with previous disagreements in mind. Each region is classified according to a hierarchical system with increasing levels of injury or instability and The AO Spine Classification Group reached a consensus on a classification that incorporates both fracture morphology and clinical factors relevant for clinical decision making. However, interobserver reliability is poor, which proves to be the defining pitfall of this tool. from publication: Treatment of Injuries to the Subaxial Cervical Spine . Injury mechanism was distinctly different in the 5 classes of the AOSpine subaxial cervical spine injury classification system. In the current AOSpine Trauma Classification, the spinal column is divided into 4 regions: the upper cervical spine (C0-C2), subaxial cervical spine (C3-C7), thoracolumbar spine (T1-L5), and the sacral spine (S1-S5, including coccyx).

The objective of this study was to use the AOSCIS and compare it to the widely used Allen classification (AC) based on mechanics for subaxial cervical spine injury. The Subaxial Cervical Spine Injury Classification System (SLIC) is widely used and evaluates not only fracture morphology but also considers ligamentous injury and neurological status in surgical decision making. 2019 Aug. 28 (8):1855-1863. . It showed substantial inter- and intraobserver agreement in the study describing it; however, an independent evaluation has not been performed. Here, the system was studied in relation to injury severity along with admission and long term neurologic follow-up. Anteroposterior and lateral radiographs, computed tomography scans, and magnetic resonance imaging of 65 patients with acute traumatic subaxial cervical spine injuries were selected and classified . AO Spine classification of upper cervical injuries. The new AOSpine thoracolumbar spine injury classification system is based on the evaluation of 3 basic parameters: 1.
