Preoperative anteroposterior and lateral standing radiographs obtained in a 54-year-old man with low-grade spondylolisthesis. Spinopelvic parameters were as follows: 73° sacral slope, 82° lumbar lordosis, 12° pelvic tilt, and 94°pelvic incidence.

Schematic of reverse Bohlman approach for transvertebral transsacral cage placement in treatment of low-grade spondylolisthesis. (a) Creation of a tract across the L5 and S1 vertebral bodies. (b) Sequential dilation of tract using a series of drills and reamers. (c) Transvertebral transsacral cage placement.

Intraoperative lateral radiographs demonstrating transvertebral transacral cage placement. (a) Creation of guide tract across L5 and S1 vertebral bodies, (b) dilation of tract using a series of drills and reamers, (c) initial cage placement, and (d) cage in final position.
