Paramedian Tangential Approach for the Lumbosacral Extraforaminal Disc Herniations

• Roh SW
• Rhim SC

Abstract

OBJECTIVE
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).
METHODS
Two patients with lumbosacral extraforaminal disc herniations were operated using paramedian tangential approach.
RESULTS
Using this new approach, lumbosacral extraforaminal disc herniations could be operated with safety and minimal amount of nerve root manipulation.
CONCLUSION
This paramedian tangential approach seems to be one of good surgical options for lumbosacral extraforaminal disc herniations.
