Anterolateral retroperitoneal psoas-sparing lumbar interbody fusion outcomes.

Anterolateral Retroperitoneal Psoas-sparing, Anterior to Psoas (ATP) or oblique lateral interbody fusion (OLIF) is a psoas sparing technique postulated to decrease iatrogenic lumbar plexus injury. The goal of this paper is to assess the outcomes of the OLIF interbody fusion technique. OLIF procedures have a high rate of fusion with a low rate of complications particularly from L2-L5. Complications are more common, although still low, from L5-S1, primarily including cage subsidence and vascular injury. The Anterolateral Retroperitoneal Psoas-sparing approach to lumbar interbody fusion is a safe approach with a low complication and high fusion rate, resulting in excellent clinical and radiographic outcomes.
