Long-term clinical and radiographic outcomes of the Prestige LP artificial cervical disc replacement at 2 levels: results from a prospective randomized controlled clinical trial

OBJECTIVE The aim of this study was to assess long-term clinical safety and effectiveness in patients undergoing anterior cervical surgery using the Prestige LP artificial disc replacement (ADR) prosthesis to treat degenerative cervical spine disease at 2 adjacent levels compared with anterior cervical discectomy and fusion (ACDF).   Read More...

Cervical disc arthroplasty with the Prestige LP disc versus anterior cervical discectomy and fusion, at 2 levels: results of a prospective, multicenter randomized controlled clinical trial at 24 months

OBJECTIVE The authors compared the efficacy and safety of arthroplasty using the Prestige LP cervical disc with those of anterior cervical discectomy and fusion (ACDF) for the treatment of degenerative disc disease (DDD) at 2 adjacent levels.   METHODS Patients from 30 investigational sites were randomized to 1 of 2 groups: investigational patients (209) underwent arthroplasty using a Prestige LP artificial disc, and control patients (188) underwent ACDF with a…

Access strategies for revision or explantation of the Charité lumbar artificial disc replacement

Todd H. Lanman, MD, FAANS, FACS (et al)   Many lumbar disc prostheses are constantly in development. The goal in each is to preserve mobility in patients with degenerative disc disease. In this study, Dr. Lanman and his colleagues examine the advantages and disadvantage of lumbar artificial disc replacement (ADR) compared with anterior interbody fusion (ALIF). Mainly, the physicians are concerned with the potential for displacement of the implants or…

The Latest Lessons Learned from Retrieval Analyses of Ultra-High Molecular Weight Polyethylene, Metal-on-Metal, and Alternative Bearing Total Disc Replacements

Todd H. Lanman, MD, FAANS, FACS (et al)   The field of cervical and lumbar total disc replacements is expanding as physicians gain better understanding of how the body responds to various treatments. Dr. Lanman was one of several physicians who shared their expert knowledge regarding the human body's reaction to various devices and surgical techniques. This study addressed physician observation about the advancements that have been made in understanding…

Retrieval analysis of PEEK rods for posterior fusion and motion preservation

Todd H. Lanman, MD, FAANS, FACS (et al)   A new synthetic rod system was introduced in 2006 as an alternative for metallic rods often used for posterior spinal fusion. The new rod design is intended to improve motion preservation for patients that need spinal fusion surgery. The new rods are made from a compound called polyaryl-ether-ether-ketone or "PEEK." Dr. Lanman participated in this study to analyze how PEEK rod…

UHMWPE Wear Debris and Tissue Reactions Are Reduced for Contemporary Designs of Lumbar Total Disc Replacements

Todd H. Lanman, MD, FAANS, FACS (et al)   Lumbar total disc replacement is a surgical procedure that is used to relieve back pain and maintain maximum physical mobility in patients. Medical technology is rapidly developing to give patients new options for surgical implants. The newest devices bond metal and synthetic materials (polyethylene) with surgical techniques that form a durable bond with bone. This study was intended to evaluate the…
