“…The incidence of device removal during this time was higher than in some other studies [14,15] but lower than in others [17,18]. In a recently published systematic review of the effectiveness of interspinous implant surgery in a total of 563 patients with NIC, 6 % of devices were found to have required replacement or reoperation [19].…”

“…Spinous process fracture, observed here and in other studies of IPDs, may be considered as potentially risk related specifically to interspinous process decompression, both in terms of the procedure and the device itself [11][12][13][14]. Fracture rates, and the means of detecting fractures, vary between studies, making direct comparisons difficult.…”

Purpose New interspinous process decompression devices (IPDs) provide an alternative to conservative treatment and decompressive surgery for patients with neurogenic intermittent claudication (NIC) due to degenerative lumbar spinal stenosis (DLSS). APERIUS Ò is a minimally invasive IPD that can be implanted percutaneously. This multicentre prospective study was designed to make a preliminary evaluation of safety and effectiveness of this IPD up to 12 months post-implantation. Methods After percutaneous implantation in 156 patients with NIC due to DLSS, data on symptoms, quality of life, pain, and use of pain medication were obtained for up to 12 months.Results Early symptom and physical function improvements were maintained for up to 12 months, when 60 and 58 % of patients maintained an improvement higher than the Minimum Clinically Important Difference for Zurich Claudication Questionnaire (ZCQ) symptom severity and physical function, respectively. Leg, buttock/groin, and back pain were eased throughout, and the use and strength of related pain medication were reduced. Devices were removed from 9 % of patients due to complications or lack of effectiveness. Conclusions Overall, in a period of up to 12 months follow-up, the safety and effectiveness of the APERIUS Ò offered a minimally invasive option for the relief of NIC complaints in a high proportion of patients. Further studies are underway to provide insight on outcomes and effectiveness compared to other decompression methods, and to develop guidance on optimal patient selection.

“…It should be noted that this range is not dissimilar to that reported for open surgical decompression. Interspinous process spacers are also considered to be less invasive than open surgery, but reports of safety and patient outcomes remain highly controversial with these implants [22][23][24][25].…”

SUMMARY Lumbar spinal stenosis is one of the most common degenerative diseases of the elderly population, and a major cause of debilitating pain and decreased function. Lumbar spinal stenosis is almost always associated with neurogenic claudication characterized as pain worsened by standing or walking and relieved by lumbar flexion or sitting. While initial treatment of lumbar spinal stenosis may involve conservative therapies, as patients become more symptomatic the traditional treatment path has generally led to open laminectomy and other invasive, potentially destabilizing, procedures. More recently, less invasive alternatives to wide laminectomy have been developed. This article describes a new method of percutaneous lumbar decompression for treatment of neurogenic claudication secondary to lumbar spinal stenosis, the minimally invasive lumbar decompression procedure. We review the steps of successfully decompressing the hypertrophic ligamentum flavum and lamina, thereby alleviating pressure on neural structures. This is a major innovation in patient care and a step to reduce risks while minimizing costs.
