Supporting Research for the AccuraScope Procedure

Many groups that talk about minimally invasive procedures have little to no clinical research to back up their claims. The minimally invasive spine surgery experts working with North American Spine practice the most conservative, least invasive medicine possible to achieve superior results.

They use an evidence-based approach that is specially tailored to the symptoms and pathology of each individual patient and treatment options range from epidural steroid injections, to AccuraScope procedures all the way up to minimally invasive fusions and even open back surgeries in situations where that is what the patient needs. Independent, peer-reviewed research is a cornerstone of evidence-based medicine.

Current Trends in Minimally Invasive Spinal Surgery

Journal of Neurosurgical Review
Authors: Erich O. Richter, Marina V. Abramova, & Jason C. Mussell

The past 30 years has seen a dramatic expansion in the technologies available to practitioners of interventional pain management for the spine. This survey article spans the historical development from spinal decompression and fixation techniques to the most recent endoscopic and laser based therapies. This review is based on the six basic mechanisms for reducing pain of spinal origin: 1) anti-inflammatory/analgesic; 2) lysis of scar/de-tethering; 3) decompression; 4) arthrodesis/fixation; 5) neural ablation; and 6) neuromodulation. Multiple therapeutic modalities are summarized in each of these domains including; intradiscal electrothermy, epiduroscopy with laser ablation, percutaneous or endoscopic instrumentation and arthrodesis, vertebral augmentation, interspinous process decompression, percutaneous removal of the ligamentum flavum, intrathecal medication infusion, and spinal cord or peripheral nerve, neuromodulation. Intracranial pain techniques are beyond the scope of this article. Each technique is addressed from the standpoints of basic concepts and anatomy, as well as efficacy and complications.

Epiduroscopic Laser Disc and Neural Decompression

This study sought to evaluate the effectiveness of epiduroscopic disc and neural decompression with laser to epiduroscopic neural decompression alone, among patients with chronic refractory low-back and/or leg pain. A total of 109 patients with chronic low-back and/or leg pain were operated on epiduroscopically, with or without the addition of laser-based disc and neural decompression. Eleven patients were excluded because they had not yet met the minimum 6-month follow-up period criterion. The clinical outcomes of 20 epiduroscopic neural decompression (END) patients, and 78 epiduroscopic laser disc and neural decompression (ELND) patients were evaluated during a follow-up period. Outcomes were evaluated using the visual analog scale (VAS) for back and leg pain, the Roland Morris Disability Questionnaire (RMDQ), and Mac Nab criteria. Among END patients, the mean back and/or leg pain VAS score improved from 8.5 to 4.6 one month after the operation. For ELND patients, the mean back and/or leg pain VAS score improved from 7.6 to 4.9 one month after the operation. The long-term END follow-up patients reported mean back and/or leg pain VAS score change from the initial 8.5 to 6.1, and for ELND patients from the initial 7.6 to 3.6. Mean RMDQ scores improved from 11.3 to 9.6 with END, and from 18.8 to 11.4 with ELND during the 1-month follow-up period. However, in the long-term follow-up data, the mean RMDQ score worsened from initial means of 11.3 to 11.4 for END patients but continued to improve from the one month mean of 11.4 to 10.6 for ELND. Results using the Mac Nab criteria were positive in 82% of the ELND group compared to 45% with the END group.Eighty-two percent of the patients treated with ELND (laser disc and neural decompression) reported positive treatment results as opposed to 45% receiving END alone (non laser neural decompression). Thus ELND, with its considerably higher percentage of positive outcomes, is judged to be a more effective therapeutic modality for patients with chronic refractory LBP.

Minimally Invasive Lumbar Decompression for Spinal Stenosis

Journal of Neurosurgical Review
Authors: Timothy R. Deer, Nagy Mekhail, Gabriel Lopez, & Kasra Amirdelfan

Over 1.2 million patients are diagnosed with, and in active treatment for lumbar spinal stenosis (LSS) at any given time. Typically, these patients experience discomfort while walking or standing, for any length of time. The LSS treatment algorithm contains a gap of under-treated patients between epidural steroid injections (ESI) and open surgery. With the introduction of a minimally invasive lumbar decompression, or mild®, procedure (Vertos Medical) for spinal stenosis, the LSS patient no longer needs to suffer under-treatment or undergo major lumbar surgery. mild® makes it is possible to address this progressive disease with a progressive option.
