Methods: In this prospective cohort study, two orthopedics patients’ groups and mTBI patients were studied to assess the biomarkers’ ability in prevention unnecessary brain CT scan at the emergency setting. There were 40 orthopedics’ patients with single extremity fracture and 41 mTBI patients. Brain CT scans were done for all mTBI patients. Results: Brain CT scans showed no intracranial traumatic lesions. The median levels for S100B in the mTBI group was 14.8 (4.4-335.9) ng/L, and in orthopedic patients’ group was 13.3 (5-353.10) ng/L. Statistically significant differences were observed between both groups in S100B levels (p=0.006). The median Glial Fibrillary Acidic Protein (GFAP) levels in the mTBI patients’ group were 600 (400-16300) and in the orthopedic patients’ groups was 60 ng/L (300-14900). Statistically significant differences were observed between groups in GFAP (p=0.041). Conclusion: Our results showed that S100B and GFAP serum levels were significantly higher in patients with mTBI than in patients with a single limb fracture. %U https://beat.sums.ac.ir/article_47631_ff54b87a5957765a325dab67689d4bb4.pdf
