Clinical outcomes with endoscopic resection of lumbar extradural cysts.

J Spine Surg 2020 Jan;6(Suppl 1):S133-S144

Center for Advanced Spine Care of Southern Arizona and Surgical Institute of Tucson, Tucson, USA.

Background: Lumbar extradural cysts may be associated with sciatica-type back and leg pain. The symptoms of clinical pain syndrome from synovial cysts are sometimes difficult to differentiate from those of lumbar disc herniation or spinal canal stenosis and may be identified to be a pain source when visualized endoscopically. The authors analyzed the clinical outcomes with their endoscopic resection to better establish clinical indications and prognosticators of favorable results. Read More
