Importance of Skull X-ray in Head Trauma
Abstract
PURPOSE OF THE STUDY The aim of our study is to show the pitfalls of performing skull X-rays in patients with head injuries and the lack of accuracy of this examination nowadays, and to clarify the current trend in the MTBI investigation algorithm. MATERIAL AND METHODS A retrospective study of 3,950 patients treated for acute head injury at the Department of Trauma Surgery (University Hospital Brno) in the period from 2015 to 2016. Inclusion criteria were the following: mild brain injury (GCS = 15), primary skull X-ray design in head injury diagnosis. Patients with a positive skull X-ray finding underwent a head CT evaluation up to 24-hours from the injury except for the patients with an isolated nose bone fracture. A CT head scan was also performed in patients indicated by the neurologist at the initial examination based on the anamnestic data and an objective finding. RESULTS Inclusion criteria were met by 1,938 patients. In 1806 (93.2%) cases the X-ray was negative, in 132 (6.8%) patients the X-ray was positive, of which in 62% of patients a nasal fracture was detected. A skull fracture reported in 16 cases. Once the CT scan of the head was obtained, all of these cases were classified as false negative. After the CT scan of the head, intracranial bleeding was observed in 12 patients, in 4 cases accompanied by fractures of the skull, not visible on the X-ray images. After the statistical evaluation, the sensitivity and specificity of the X-ray examination compared to the…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 3,950 participants or records.
