Five-year results of lumbar disc prostheses in the SWISSspine registry

Abstract

Lumbar TDA appeared as efficient in long-term pain alleviation, consequent reduction of pain medication consumption and improvement of quality of life. The procedure also appeared sufficiently safe, but surgeons have to be aware of a list of potential adverse events. The outcome is stable over the 5-year postoperative period. The vast majority of treated segments remained mobile after 5 years, although almost half of patients showed osteophytes.

Total disc replacement versus multidisciplinary rehabilitation in patients with chronic low back pain and degenerative discs: 8-year follow-up of a randomized controlled multicenter trial

“…In a recent international spine registry study [313], the results of cervical disc replacement were in accordance with those in the published RCTs. Furthermore, in a Swiss registry study with five-year follow-up after lumbar TDR [197], the main results are similar to those in RCTs with a follow-up time of at least five years (Appendix, Table 1). Our results are in line with two small single centre Norwegian observational studies [314 315], while, in the Norwegian Spine Registry (2007-2013), the one-year mean improvement following TDR was 26.0 ODI points as compared to 22.5 ODI points after one year in the Norwegian TDR Study [316].…”

Künstliche Bandscheibe in der Lendenwirbelsäule – Hype oder Hope?

“…In einer Anwendungsbeobachtung mit 2 Jahren Nachuntersuchungszeitraum traten keine implantatbedingten Komplikationen auf [43]. Die Gesamtkomplikationsrate liegt zwischen 10 % und 23 % [25,26,33,47,48,49].…”

“…Die Revisionsrate lag bei 4,4 %. Nach 5 Jahren waren 87 % der operierten Segmente noch mobil, obwohl sich bei 44 % heterotope Ossifikationen gebildet hatten [47].…”

Viscoelastic Disc Arthroplasty Provides Superior Back and Leg Pain Relief in Patients with Lumbar Disc Degeneration Compared to Anterior Lumbar Interbody Fusion

“…This segment also showed relatively high revision rates in previous analyses. 13 Furthermore, monosegmental surgery appears to lead to an up to 1 NRS point higher pain relief than bisegmental surgery. We believe that this finding may be attributable to generally worse conditions of patients with multiple affected levels.…”

“…4 The 5-year results of 248 lumbar TDRs in the SWISSspine registry showed significant and longlasting back and leg pain relief from 7.2 and 5.5 Visual Analog Scale (VAS) points preoperative to 2.8 and 2.2 points postoperative at the fifth postoperative year. 13 It should be noted that the implants used in this study were implanted in the years 2005 and 2006 and still represent the first generation of lumbar disc arthroplasties. An even further alleviated back and leg pain with compliant second generation lumbar disc prosthesis like VTDR may be potentially well explained by further improvement of disc prosthesis design and material properties, instrumentation, improved and stricter patient selection and comprehensive surgical experience.…”
