Study Design: Retrospective cohort study.

Objectives: (1) To compare the risk of Spinal Epidural Hematoma (SEH) associated with specific pre-operative and post-operative anticoagulation (AC) and antiplatelet medications (APM). (2) To define the incidence of SEH and identify risk factors for SEH in our population.
