STUDY DESIGN: Analysis of a prospective multicenter database. OBJECTIVE: To assess the ability of the recently created Adult Spinal Deformity (ASD) Frailty Index (ASD-FI) to predict odds of major complications and length of hospital stay for patients who had more severe preoperative deformity and underwent more invasive ASD surgery compared with patients in the database used to create the index. SUMMARY OF BACKGROUND DATA: Accurate preoperative estimates of risk are necessary given the high complication rates currently associated with ASD surgery...

BACKGROUND CONTEXT: Predictors of outcome after surgery for degenerative cervical myelopathy (DCM) have been determined previously through hypothesis-driven multivariate statistical models that rely on a priori knowledge of potential confounders, exclude potentially important variables due to restrictions in model building, cannot include highly collinear variables in the same model, and ignore intrinsic correlations among variables. PURPOSE: To apply a data-driven approach to identify patient phenotypes that may predict outcomes after surgery for mild DCM...

OBJECTIVE: Currently, no spinal classification system has achieved universal acceptance. Therefore, it is important to choose a reliable classification within clinical practice. The objective of this study was to determine and compare the intra- and inter-observer agreement of the Load Sharing Classification (LSC), the Thoracolumbar Injury Classification System (TLICS) and the AOSpine Thoracolumbar Spine Injury Classification System. METHODS: In this web-based intra- and inter-observer study (www...

BACKGROUND: There is controversy over the optimal treatment strategy for patients with mild degenerative cervical myelopathy (DCM). OBJECTIVE: To evaluate the degree of impairment in baseline quality of life as compared to population norms, as well as functional, disability, and quality of life outcomes following surgery in a prospective cohort of mild DCM patients undergoing surgical decompression. METHODS: We identified patients with mild DCM (modified Japanese Orthopaedic Association [mJOA] 15 to 17) enrolled in the prospective, multicenter AOSpine CSM-NA or CSM-I trials...

BACKGROUND: Spine surgeons are exposed to high amounts of radiation from fluoroscopic procedures during their lifetime. In this study, we evaluated spine surgeons' knowledge of and attitude regarding radiation exposure during spine surgery. METHODS: We developed a questionnaire including questions about surgeons' characteristics and knowledge of and attitude regarding radiation exposure during spine surgery. A survey was performed with the members of AOSpine Latin America...

BACKGROUND: Vertebral body fractures (VBF) can be caused by various trauma mechanisms. The AOSpine classification system differentiates three main types of fractures according to the grade of instability. How the increasing energy of various accident mechanisms changes the complexity of the individual fracture, its localization and the occurrence of further fractures has not yet been finally investigated. OBJECTIVE: What influence do traumatic events with different kinematics have on the localization, complexity and number of VBF in the thoracic and lumbar spine? MATERIAL AND METHODS: In this retrospective study data from patients with a freshly traumatized VBF were analyzed...

STUDY DESIGN: Sub-analysis of the prospective AOSpine CSM North America and International studies. OBJECTIVE: To describe the post-operative changes in MRI spinal cord signal intensity in degenerative cervical myelopathy (DCM) patients and to investigate the impact of its post-operative resolution on clinical outcomes. SUMMARY OF BACKGROUND DATA: When examining the spinal cord, hyperintensity found in MRI T2-weighted images and hypointensity in T1-weighted images are known to correlate with pre-operative severity of DCM and to predict post-operative neurological recovery...

OBJECTIVES: Patient-reported outcome measures (PROMs) are the most widely accepted means of measuring outcomes after spine procedures. We sought to determine the current status of worldwide use of PROMs in Latin America (LA), Europe (EU), Asia Pacific (AP), North America (NA), and Middle East (ME) to determine the barrier to its full implementation. METHODS: A questionnaire survey was sent by e-mail to members of AOSpine to evaluate their familiarity and use of PROMs instruments and to assess the barriers to their use in spine care practice in LA, EU, AP, NA, and ME...

Traumatic thoracolumbar burst fractures are one of the most common forms of spinal trauma with the majority occurring at the junctional area where mechanical load is maximal (AOSpine Thoracolumbar Spine Injury Classification System Subtype A3 or A4). Burst fractures entail the involvement of the middle column, and therefore, they are typically associated with bone fragment in the spinal canal, which may cause compression of the spinal cord, conus medullaris, cauda equina, or a combination of these. Fortunately, approximately half of the patients with thoracolumbar burst fractures are neurologically intact due to the wide canal diameter...

This article focuses on patient-reported and clinician-reported outcome measures in spine trauma care. The measurement of the quality of care and functional and health-related quality of life outcomes of spine trauma patients has become increasingly important. However, no outcome instrument is specifically designed, validated, or universally adapted for this specific patient population. Issues specific to spinal trauma patients may not be adequately addressed by the instruments that are currently used in the literature and the daily clinical practice...

INTRODUCTION: Cervical spine injury classification systems should be simple, easy to relate and remember, reliable guide for surgical planning, and predictor of outcome in clinical settings. We investigated whether the AOSpine subaxial cervical spine classification system predicted injury severity and neurologic outcome. MATERIAL AND METHODS: We analyzed the relevant clinical, imaging, management, and American Spinal Injury Association (ASIA) impairment scale (AIS) grade conversion of 92 AIS grades A-C patients with cervical spine injury...

Numerous classification systems for subaxial and thoracolumbar spine injuries were proposed in the past with the attempt to facilitate communication between physicians. The AO-Magerl, thoracolumbar system, and Subaxial Cervical Spine Injury Classification systems are all well known, but did not achieve universal international adoption. A group of international experienced spine trauma surgeons were brought together by AOSpine with the goal to develop a comprehensive yet simple classification system for spinal trauma...

STUDY DESIGN: Systematic literature review with meta-analysis. OBJECTIVE: Thoracolumbar (TL) fractures can be treated conservatively or surgically. Especially, the treatment strategy for incomplete and complete TL burst fractures (A3 and A4, AOSpine classification) in neurologically intact patients remains controversial. The aim of this work was to collate the clinical evidence on the respective treatment modalities. METHODS: Searches were performed in PubMed and the Web of Science...
