Prone Transpsoas Lateral Interbody Fusion (PTP LIF) is a minimally invasive spinal fusion technique. Minimally Invasive Surgical (MIS) techniques result in faster recover and less blood loss and postoperative pain compared to traditional techniques.

Minimally Invasive Spine Surgery differs from traditional, open spine surgery in that fusion is achieved primarily through the interbody space rather than the posterolateral gutter.
