Prepsoas oblique lateral lumbar interbody fusion in deformity surgery.

Interbody fusions are routinely used in deformity surgery to achieve both coronal and sagittal correction and attain increased fusion rates. Minimally invasive interbody techniques, including the prepsoas approach, are being utilized to decrease tissue disruption, blood loss, and patient morbidity with similar outcomes compared to traditional surgery. The prepsoas oblique lateral interbody fusion, accesses the spine between the iliac arteries or aorta and psoas muscle, and allows for exposure of the lumbar spine while avoiding some complications commonly seen with a direct lateral approach. Navigation can assist the surgeon for surgical planning, ensuring appropriate placement of the interbody graft, and with placement of posterior pedicle screws. In correctly selected patients, these minimally invasive procedures can achieve excellent deformity correction and outcomes.
