abstract="BACKGROUND: In April of 2012, Michigan repealed its 35-year-old universal motorcycle helmet law in favor of a partial helmet law, which permits motorcyclists older than 21 years old with sufficient insurance and experience to drive un-helmeted. We evaluated the clinical impact of the repeal. <br><br>METHODS: The Michigan Trauma Quality Improvement Program's trauma database was queried for motorcycle crash patients between 1/1/09-4/12/12 and between 4/13/12-12/31/14. <br><br>RESULTS: There were 1970 patients in the pre-repeal analysis and 2673 patients in the post-repeal analysis. Following the repeal, patients were more likely to be un-helmeted (p < 0.001) and to have a traumatic brain injury (p < 0.001). Patients were also more likely to require neurosurgical interventions (relative risk 1.4, p = 0.011). <br><br>CONCLUSION: Following the repeal of the universal helmet law, there has been a significant increase in traumatic brain injuries and neurosurgical interventions. This analysis highlights another detrimental impact of the repeal of the universal helmet law. SUMMARY SENTENCES: Following the repeal of the universal helmet law, there has been a significant increase in traumatic brain injuries and neurosurgical interventions. This analysis highlights another detrimental impact of the repeal of the universal helmet law.<br><br>Copyright © 2017 Elsevier Inc. All rights reserved.<p /> <p>Language: en</p>",
