Abstract

Degenerative lumbar spinal stenosis involves an acquired reduction in the spinal canal diameter due to osteoarthritic changes on the disk, facet joints, and ligaments and may result in spinal cord or cauda equina compression.1 This process may lead to pain radiating to the legs, neurogenic claudication, and neurologic deficit. First-line treatment includes conservative care such as physical therapy, spinal injections, and lifestyle changes. If this strategy is insufficient to achieve symptom relief, surgical management is recommended.1,2 Surgery generally encompasses a decompression procedure through a posterior approach. There are several techniques to accomplish this in the context of severe bilateral stenosis including standard open laminectomy, unilateral laminectomy with bilateral decompression, and a tubular approach with bilateral decompression (e.g., “over-the-top technique”).2 Among these, the spinous process splitting laminectomy has emerged as a strategy that allows decompressing the spinal canal through a familiar anatomy to the surgeon while respecting paravertebral muscles.3,4 This technique involves exposure of the laminae by cutting through the spinous process and then separating both halves and muscles attached at the sides. The main advantage is that the insertion of these paravertebral soft tissues is preserved, the required retraction is reduced and postoperative pain is decreased.4 Moreover, the learning curve to achieve a successful decompression employing the splitting laminectomy is substantially shorter than with other minimally invasive approaches, such as tubular. This video aims to show the steps to perform this technique (Video 1). We report the case of a 74-year-old male who presented with left sciatica and neurogenic claudication. The images showed multilevel degenerative lumbar spinal stenosis, with severe bilateral compression at L4-5, without signs of instability. Surgical alternatives were discussed with the patient, and it was decided to perform an L4-5 spinous process splitting laminectomy. The patient had a good evolution with an unremarkable postoperative course.
