In Vitro Biomechanics of Lumbar Disc Arthroplasty with the Prodisc Total Disc Implant
نویسندگان
چکیده
An alternative approach to lumbar fusion surgery is to restore motion to the diseased segment with a disc prosthesis. The goal of the disc prosthesis is to replace the diseased disc while preserving and/or restoring the motion at the operated spinal level. The purpose of this study was to determine the ability of the PRODISC® (Spine Solutions Inc., Paoli, PA) disc prosthesis to restore lumbar spine motion and compare this motion to that of the harvested and fused spines.

The activL® Artificial Disc: a next-generation motion-preserving implant for chronic lumbar discogenic pain
Degeneration of the lumbar intervertebral discs is a leading cause of chronic low back pain in adults. Treatment options for patients with chronic lumbar discogenic pain unresponsive to conservative management include total disc replacement (TDR) or lumbar fusion. Until recently, only two lumbar TDRs had been approved by the US Food and Drug Administration - the Charité Artificial Disc in 2004 ...

BACKGROUND Although total disc replacement has been performed for years outside the United States, relatively little available data address clinical outcomes, particularly data from prospective studies. We report the 24- to 36-month follow-up of one center's experience with the ProDisc-L artificial disc as part of a prospective, randomized trial comparing total disc arthroplasty to combined ant...

INTRODUCTION: Design of total disc replacement (TDR) prosthesis plays an important role in the long-term clinical performance of these implants. Prodisc-L (Spine Solutions, Inc. Synthes, Paoli, PA, USA), a semi-constrained TDR system, has a ball-and-socket based design; whereas SB Charité III (DePuy Spine, Inc, Raynham, MA, USA) has a theoretically unconstrained articulation which allows the mo...

STUDY DESIGN Prospective nonrandomized clinical series. OBJECTIVES To evaluate the efficacy of ProDisc lumbar artificial disc replacement (ADR) in smokers versus nonsmokers. SUMMARY OF BACKGROUND DATA Smoking is a negative predictor in fusion surgery. To date, a prospective study of the treatment of incapacitating discogenic low back pain using ADR in smokers versus nonsmokers has not been ...
