Abstract

Purpose: Computer-assisted spinal surgery is getting popular, however there is no technical report which describes the technique of oblique lumbar interbody fusion (OLIF) and percutaneous pedicle screw fixation (PPS) without C-arm fluoroscopy in the lateral position.

Methods: The authors report the result of 2-year follow-up of a 69-year-old female patient with L4 degenerative spondylolisthesis. The patient has suffered low back pain and intermittent claudication for more than 4 years. The authors performed C-arm free OLIF and PPS in a single lateral position.

Results: The patient was successfully treated with surgery and lumbar alignment was preserved correctly. She had neither neurological deficits nor low back pain at 2 year of final follow-up.

Conclusion: The C-arm free OLIF and lateral PPS is useful technique, especially in that the surgeons and OR staff have no risk of adverse event of radiation.
