IntroductionMany of the injury mechanisms that cause mild traumatic brain injury (mTBI) also create forces commonly associated with whiplash, resulting in cervical pain injury. The prevalence of associated neck pain with mTBI is not well established. There is a strong indication that injury to the cervical spine may aggravate, cause, and/or impact recovery of symptoms and impairments associated with the concussive event and its primary effect on the brain. The purpose of this study is to help identify the prevalence of ensuing cervical pain within 90 days of a previously documented mTBI and to examine the role of neck pain during concurrent concussive symptoms, in a military population stationed at a large military installation.Materials And MethodsThis retrospective design utilized a de-identified dataset using predetermined search and filter criteria, which included male active duty service members (SMs), 20 to 45 years of age, who received medical care at any clinic on Fort Liberty (Fort Bragg, NC) during fiscal year (FY) 2012 to FY 2019, with documented cervicalgia and mTBI (via the International Classification of Diseases, 9th and 10th Revision, Clinical Modification codes), verified using electronic medical records. The final dataset served as the basis for subject sampling and was analyzed to determine the total number of documented cervicalgia and mTBI diagnoses. Results are presented as descriptive statistics. Approval for this study was received from the Andrews University Office of Research (18-097) and the Womack Army Medical Center Human Protections Office.ResultsBetween FY 2012 and FY 2019, 14,352 unique SMs accessed a Fort Bragg, NC health care facility, at least once (Table I). Overall, 52% of SMs diagnosed with cervicalgia were found to have a previously diagnosed mTBI during the 90 days before the cervicalgia diagnosis. In contrast, the prevalence of same-day cervicalgia and mTBI diagnosis was <1% (Table IV). The prevalence of isolated cervicalgia diagnosis at any time during the reporting period was 3%, whereas isolated mTBI diagnosis was 1% (Table III).ConclusionsOver 50% of SMs diagnosed with cervicalgia had sustained a documented mTBI within 90 days prior, whereas less than 1% were diagnosed with cervicalgia at the time of initial primary care or emergency room encounter following the mTBI event. This finding suggests that the close anatomical and neurophysiological connections between the head and the cervical spine are both likely to be impacted through the same mechanism of injury. Delayed evaluation (and treatment) of the cervical spine may contribute to lingering post-concussive symptoms. Limitations of this retrospective review include the inability to assess the causality of the relationship between neck pain and mTBI, as only the existence and strength of the prevalence relationship can be identified. The outcome data are exploratory and intended to identify relationships and trends that may suggest further study across installations and across mTBI populations.Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2023.
