The purpose of this study was to establish the incidence of MRI‐detectable hematomas following paraspinal EMG. We provide a retrospective review of patients who underwent paraspinal EMG and subsequent concordant level spine MRI. A total of 370 charts (431 MRIs) met the inclusion criteria. No paraspinal hematomas were observed. These results should further the development of evidence‐based guidelines for patients who have greater‐than‐normal bleeding risk and support the notion that paraspinal EMG is a relatively safe procedure.
