Efficacy of Nucleo-Annuloplasty Using Disc-Fx in Lumbar Disc Herniation

Abstract

Background: Lumbar radicular pain may be caused by lumbar disc herniation, spinal stenosis, or degenerative spondylolisthesis. It is most often caused by lumbar disc herniation and presents as pain radiating from the back into the leg, usually in a dermatomal pattern corresponding to the compressed nerve root. In patients whose pain does not respond to epidural steroid injections, other treatment modalities can be considered. Minimally invasive disc decompression procedures have been developed to treat radicular pain caused by disc herniation. The Disc-FX system combines percutaneous manual discectomy using forceps, nuclear ablation, and annular modification using radiofrequency equipment. To our knowledge, no reports of a correlation between response to Disc-FX and type of lumbar disc herniation have been published. The aim of this study was to determine patients' responses to and shortterm outcomes of Disc-FX procedures.

Efficacy and safety of nucleo-annuloplasty using radiofrequency ablation for discogenic back pain in a local Hong Kong population

“…Our study results are comparable with recent studies regarding use of radiofrequency ablation including Park et al involving 43 patients with lumbar disc herniation, 16 Hellinger's prospective study of 58 patients 17 Earlier aforementioned studies also suggest that the disc-Fx procedure can be effective in the presence or absence of annular tears. Our study suggests that patients with annular tears present with statistically significant improvement post-procedure as opposed to those without annular tears.…”

“…Our study results are comparable with recent studies regarding use of radiofrequency ablation including Park et al involving 43 patients with lumbar disc herniation, 16 Hellinger’s prospective study of 58 patients 17 and Kumar et al’s 4 prospective analysis of 51 patients with Disc-Fx interventions which suggest that Disc-Fx may be helpful in providing improvement or favorable outcomes in discogenic back pain.…”

An Effectiveness Evaluation of Nucleo-Annuloplasty for Lumbar Discogenic Lesions Using Disc-FX: A Scoping Review

“…Following a title and abstract screening, which eliminated 5 irrelevant articles, the remaining 17 possibly relevant articles were obtained. Following a thorough examination of the complete text, 15 articles were finally included in this review [ 13 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. Figure 1 shows a flowchart for a specific study.…”

A Case of Thoracic Disc Herniation Effectively Treated with Interventional Radiology Computed Tomography- Guided Percutaneous Endoscopic Radiofrequency Annuloplasty Using a Disc-Fx®

“…As one such technique, the Disc-Fx ® was developed. This technique uses Trigger-Flex ® and Surgi-Max ® for nucleus pulposus transpiration by percutaneous high-frequency intervertebral disc decompression or fiber ring thermocoagulation in the process of intra-disc highfrequency thermocoagulation in addition to conventional nucleus pulposus extenteration with forceps (Hijikata's procedure) [3,4,8].…”

“…PD has subsequently been modified to be a safer, noninvasive procedure, and has been applied in various forms, such as with the use of laser, including the Disc-Fx ® . The Disc-Fx ® facilitates nucleus pulposus transpiration or fiber ring thermocoagulation in addition to conventional nucleus pulposus extenteration using forceps (Hijikata's procedure) [3][4][5]. In this study, we report a patient for whom Interventional Radiology-Computed Tomography (IVR-CT)-guided Percutaneous Endoscopic Radiofrequency Annuloplasty (PERA) was performed for the thoracic disc herniation to reduce the incidence of complications and improve treatment results, leading to a favorable outcome [6].…”
