title: Risk of hematoma following needle electromyography of the paraspinal muscles.
abstract: 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.
