Oblique lumbar interbody fusion (OLIF) is one of surgical techniques for patients with spondylolisthesis, but an insertion of cage at an ideal location (anterior 1/3 of disc space) is challenging for patient with high grade spondylolisthesis, because vertebra are not aligned. Recently, a technique of simultaneous insertion of pedicle screw and rod system from the back of patient and insertion of cage via retroperitoneal route from the front of patient is possible by using spinal navigation system (OLIF-360). The author present a case and surgical technique of simultaneous re-alignment of high-grade spondylolisthesis at L4-5 and insertion of interbody cage by using OLIF-360. An intervertebral cage was inserted at the ideal location after re-alignment of spondylolisthesis with OLIF-360. Postoperative images showed re-aligned vertebra and successful decompression. The specific utilization of OLIF-360 has not been underscored yet.
