Abstract
Background: Lumbar spinal stenosis (LSS) with neurogenic intermittent claudication (NIC) is one of the most common degenerative spinal diseases in the elderly. One treatment option for LSS/neurogenic intermittent claudication is conservative management with oral analgesics, injections and physical therapy. Another relatively new operative alternative is interspinous process decompression. To date, there is no convincing evidence that these devices provide any patient benefits.Methods: This study is intended as a prospective, randomized, pilot-study to compare the safety and effectiveness of a minimally invasive, percutaneously implanted interspinous process decompression device with nonoperative treatment of LSS. Patients are randomized for surgical or nonsurgical treatment. The surgical group will undergo percutaneous implantation of an interspinous device (Aperius™ PercLID, Medtronic). The control group will receive nonoperative treatment with oral nonsteroidal anti-inflammatories, injections such as ep...
