Abstract
Atlanto-occipital dissociation (AOD) is an extremely common injury but often fatal. In a systematic review from 2010, AODs were present in almost 20% of blunt trauma fatalities. It is an injury many patients do not survive; therefore, few are treated, even at high volume trauma centers. In survivors, his injury is often missed or the diagnosis is often delayed. Mortality rates commonly reach beyond 60% when injury patterns go unrecognized. Approximately 50% of patients with AOD sustain blunt cerebrovascular injury and nearly 20% of patients present with traumatic brain injury (TBI) or stroke. This pathology was once considered uniformly fatal. However, over the last 20 years, significant advancements have been made both clinically and radiographically, to better identify and manage this injury pattern. Despite improvements in clinical comprehension and improved time to diagnosis, less than 75% of cases are currently recognized within 24 hours. Less than 40% of patients who suffer AOD are independent with functionality, without neurological impairment. This article reviews current literature regarding AOD in hopes to improve timing to diagnosis, subsequent prognosis, timing to fixation or stabilization, and postoperative recovery.
期刊介绍:
Clinical Spine Surgery is the ideal journal for the busy practicing spine surgeon or trainee, as it is the only journal necessary to keep up to date with new clinical research and surgical techniques. Readers get to watch leaders in the field debate controversial topics in a new controversies section, and gain access to evidence-based reviews of important pathologies in the systematic reviews section. The journal features a surgical technique complete with a video, and a tips and tricks section that allows surgeons to review the important steps prior to a complex procedure.
Clinical Spine Surgery provides readers with primary research studies, specifically level 1, 2 and 3 studies, ensuring that articles that may actually change a surgeon’s practice will be read and published. Each issue includes a brief article that will help a surgeon better understand the business of healthcare, as well as an article that will help a surgeon understand how to interpret increasingly complex research methodology. Clinical Spine Surgery is your single source for up-to-date, evidence-based recommendations for spine care.
