Exposure to a Motor Vehicle Collision and the Risk of Future Neck Pain: A Systematic Review and Meta‐Analysis

Abstract

ObjectiveTo summarize the literature that has examined the association between a motor vehicle collision (MVC) related neck injury and future neck pain (NP) in comparison with the population that has not been exposed to neck injury from an MVC.Literature SurveyNeck injury resulting from an MVC is associated with a high rate of chronicity. Prognosis studies indicate 50% of injured people continue to experience NP a year after the collision. This is difficult to interpret due to the high prevalence of NP in the general population.MethodologyWe performed a systematic review of the literature using five electronic databases, searching for risk studies on exposure to an MVC and future NP published from 1998 to 2018. The outcome of interest was future NP. Eligible risk studies were critically appraised using the modified Quality in Prognosis Studies (QUIPS) instrument. The results were summarized using best‐evidence synthesis principles, a random effects meta‐analysis, metaregression, and testing for publication bias was performed with the pooled data.SynthesisEight articles were identified of which seven were of lower risk of bias. Six studies reported a positive association between a neck injury in an MVC and future NP compared to those without a neck injury in an MVC. Pooled analysis of the six studies indicated an unadjusted relative risk of future NP in the MVC exposed population with neck injury of 2.3 (95% CI [1.8, 3.1]), which equates to a 57% attributable risk under the exposed. In two studies where exposed participants were either not injured or injury status was unknown, there was no increased risk of future NP.ConclusionsThere was a consistent positive association among studies that have examined the association between MVC‐related neck injury and future NP. These findings are of potential interest to clinicians, insurers, patients, governmental agencies, and the courts.Level of EvidenceI.

Advanced magnetic resonance imaging of chronic whiplash patients: a clinical practice-based feasibility study

“…Whiplash is a common injury following road traffic crashes affecting several million people worldwide each year. A significant proportion, up to 50%, develop chronic/long-term symptoms [ 1 – 3 ] and approximately 15% of those initially injured suffer from reduced working capability due to ongoing disability [ 3 ]. Chronic whiplash patients often complain of neck pain, headaches and pain in the cervico-thoracic region of the spine.…”

The Effectiveness and safety of T-MSAT on inpatients with acute low back pain caused by traffic accidents

“…After a TA, various musculoskeletal injuries, internal bruises, and psychological trauma may result, [ 9 , 10 ] while common symptoms after a TA often include neck pain or LBP. [ 11 , 12 ] One study reported that approximately 37% of patients complained of severe LBP only 6 weeks after a TA and 23% of cases involved both neck and LBP. [ 9 ] Another cohort study reported that 60.4% of patients who were treated within 30 days of an accident complained of LBP.…”

Medial Branch Blocks for Diagnosis of Facet Joint Pain Etiology and Use in Chronic Pain Litigation

“…NP is common after an injury in a motor vehicle collision (MVC) with 86% of individuals reporting neck pain, and with the pain still occurring in 50% of those individuals a year later [5,6]. In a systematic review and meta-analysis of six studies with individuals who had sustained a neck injury in a MVC, those with neck injuries were at a greater risk of future neck pain when compared to those without a neck injury (RR = 2.3 [95% CI 1.8-3.1]) [7]. Cervical pain can have multiple etiologies, including cervical dystonia, instability, protrusion, and ligamentous damage.…”
