Predictive Factors for Outcomes Following Surgical Treatment of Lumbar Disc Herniation

Lumbar disc herniation (LDH) is a common cause of radicular pain with an annual incidence between 5 and 20 cases per 1000 adults. LDH is typically treated by microdiscectomy, of which more than 300,000 are performed in the United States each year. Despite this frequency, 25% to 33% of patients report poor surgical outcomes. This study sought to present a retrospective analysis of patients who underwent microdiscectomy surgery for the treatment of LDH with the aim of identifying demographic, historical, and surgical factors that may contribute to inadequate surgical results.
