Aperius PercLID Stand Alone Interspinous System for the Treatment of Degenerative Lumbar Stenosis

Abstract

These results indicate that Aperius PercLID system offers an easy, safe, and effective treatment for patients with lumbar degenerative stenosis. Thus, this device system treatment represents a valid alternative to the traditional surgical techniques.

Clinical evaluation of the preliminary safety and effectiveness of a minimally invasive interspinous process device APERIUS® in degenerative lumbar spinal stenosis with symptomatic neurogenic intermittent claudication

“…Fracture rates, and the means of detecting fractures, vary between studies, making direct comparisons difficult. The rate of 7 % overall (including 2 % reported by the surgeons) in this study was less than has been reported in a similar study of other IPDs (29 %) [15], but is higher than in other studies where no central analysis of X-rays was undertaken [15,16].…”

“…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].…”

Posterior Vertebral Arch Cement Augmentation (Spinoplasty) to Prevent Fracture of Spinous Processes after Interspinous Spacer Implant

“…limiting extension, thus preventing the subsequent worsening of spinal canal and foraminal stenosis) undergoing compression during extension of the lumbar spine. [13][14][15][16][17][18] At that moment, provided that the bone does not fail, the extension movement, no longer obtainable due to the presence of the interspinous spacer, is now obtained at the level of different elastic structures, particularly the anterior annulus and facets, which will move opposite of the normal direction, opening instead of closing. In such conditions, an increased load is transferred to the bony structures, with consequent risk of acute or chronic failure.…”

“…From June 2007 to March 2010, we performed, at a single center, interspinous spacer implantation (Aperius PercLID, Medtronic) 3,4,[8][9][10]13,14 in all eligible patients with INC and radiologic diagnosis of central canal and/or foraminal stenosis. All patients underwent an MR imaging or CT study of the lumbar spine preoperatively, to confirm stenosis of the central canal and/or foramina and to diagnose the most severely affected levels.…”

One-Year Follow-Up of a Series of 100 Patients Treated for Lumbar Spinal Canal Stenosis by Means of HeliFix Interspinous Process Decompression Device

“…In both cases a microdiscectomy was performed, since foraminal stenosis by intraforaminal disc protrusion was persistent and it was considered to be the real cause of nerve dysfunction. The incidence of device removal during this time was low [45–48]. In a recently published systematic review regarding effectiveness of interspinous implant surgery in a total of 563 patients with NIC, 6% of devices required replacement or reoperation [49].…”
