Lumbar Spinal Fixation Removal by a Minimal Invasive Microscope-Assisted Technique. Case Report with Technical Description.

The concept of minimally invasive spine surgery (MISS) has gained increasing popularity in the last decades. While MISS holds promise for faster patient recovery, and shorter hospital stays, the removal of the surgical fixation, when required, is still performed by an extensive approach often resulting in disabling pain and discomfort. We describe a novel minimal invasive microscope-assisted technique for lumbar spinal fixation removal. This technique has been successfully applied in a 35-year-old man, affected by back pain despite a previous posterior dynamic MISS L4-S1 fixation. The previous skin incisions were opened and under microscopic vision, the screws and the roads were dissected from the scars and removed. The patient was discharged on postoperative day-1. He reported a progressive improvement of the symptoms with a satisfactory cosmetic result. Minimal invasive microscope-assisted technique for spinal fixation removal offers a simple and effective surgical alternative to the traditional open surgery.
