Even though paramedian approach has advantages over other surgical approaches for lumbar extraforaminal disc herniations, this approach has limitations for lumbosacral extraforaminal disc herniations because of narrow operative bony window. This case report is presented to describe the modified paramedian tangential approach for lumbosacral extraforaminal disc herniations(focused on surgical technique and efficacy of this approach).
Two patients with lumbosacral extraforaminal disc herniations were operated using paramedian tangential approach.
Using this new approach, lumbosacral extraforaminal disc herniations could be operated with safety and minimal amount of nerve root manipulation.
This paramedian tangential approach seems to be one of good surgical options for lumbosacral extraforaminal disc herniations.
Key Words: Extraforaminal disc herniation; Paramedian tangential approach
