Prone Trans-Psoas Lateral Interbody Fusion


What is the Prone trans-psoas lateral interbody fusion Technique?

Laminectomy, fusion, and correction of alignment frequently utilize operative approaches that expose both the anterior and posterior spine. Until now, circumferential spinal column access often requires the surgeon to reposition and drape the patient multiple times or utilize a single approach that has limited anterior correction capability or complicates otherwise traditional surgical maneuvers.  Prone Tran psoas (PTP)I s a technique utilizing a single surgical position that enables minimally disruptive anterior column correction with simultaneous access to the posterior spinal column. The PTP approach enabled efficient completion of an anterior column correction, direct posterior decompression, multi-segment pedicle fixation, and maintenance of alignment, all while in a single prone position with no intraoperative complications.

Patient Benefits:

Reduced operative time.

Reduced blood loss and minimal scarring.

Reduced postoperative pain.

Reduced hospital stay may require only an overnight stay in the hospital.

Rapid return to normal activity. Recovery is typically around 6 weeks.


Candidates for the prone trans-psoas approach include those:

Suffering from degenerative disc disease with instability.

With recurrent disc herniation.

With instability after a previous non-fusion surgery.

Who require surgery to a disc adjacent to a previous surgery.

With a disc that has slipped over another (spondylolisthesis).

With degenerative scoliosis (curvature of the spine).

With prior fusion surgeries that did not fuse (pseudarthrosis).


Many complex disorders and injuries of the spine that once required large incisions and long months of inactivity and recovery can now be corrected with San Antonio minimally invasive techniques with less muscle disruption, dramatically reduced blood loss, and early discharge home in days with minimal discomfort and lifestyle disruption.
