abstract = {Background: Lumbar facet cysts are a benign, degenerative, and fairly uncommon cause for lumbar radiculopathy. The standard surgical treatment for lumbar facet cysts often requires a laminectomy and medial facetectomy which can further destabilize a pathological motion segment. The authors present here a novel technique for transpedicular endoscopic access to the pathology that obviates the need to violate the lamina or facet.
Methods: Two patient cases are described where the lumbar 4–5 facet cysts arise medial to the pedicle. Percutaneous access to the cysts was established by drilling through the adjacent pedicle creating a 7 mm corridor to establish access for the endoscopic tubular retractor and the working channel endoscope. Straight and bendable forceps were used to remove the cysts under direct visualization.
Results: Following surgery, the patients’ symptoms showed immediate regression with complete relief of one patient’s foot drop by 6 months.
Conclusions: Transpedicular endoscopic access is described as novel minimally invasive surgical option in the awake patient for lumbar facet cysts adjacent to the Lumbar 4 or 5 pedicle.},
