Abstract:
Prone transpsoas lateral lumbar interbody fusion (PTP-LLIF) with decompression and posterior fixation in a single position is an innovative technique in spinal surgery. It establishes a direct visualization channel to the intervertebral space through the retroperitoneal approach via the psoas major in the prone position, completing interbody fusion and posterior fixation. Compared with traditional LLIF, PTP-LLIF eliminates the need for position reversal, allowing lateral decompression, posterior pedicle screw fixation, and osteotomy to be performed in the same position. This technique offers advantages such as shorter surgical time, lower infection risk, minimal trauma, and reduced blood loss, while its anatomical position changes minimize damage to abdominal organs, major vessels, and surrounding nerves. PTP-LLIF demonstrates good feasibility, safety, and clinical efficacy. This paper reviews the clinical application and research progress of PTP-LLIF, assesses its efficacy and risks, and proposes optimization directions for clinical application.
