Object Cervical total disc replacement has emerged as a surgical option to preserve motion and potentially avoid adjacent-segment disease after anterior cervical discectomy and fusion. Recently, much attention has been directed at the ability of a given device to maintain and/or restore normal segmental alignment. Nonphysiological disc and segmental angulation could result in increased stresses transmitted to the facet joints and posterior elements, conflicting with the essence of arthroplasty and potentially leading to adjacent-segment disease. The goal of this study was to contrast device alignment and segmental kinematics provided by 3 different cervical disc prostheses. Methods Sixty patients were retrospectively analyzed and divided into 3 groups receiving the Bryan, ProDisc-C, or Synergy disc. Only single-level arthroplasty cases were included in the study. Lateral dynamic radiographs of the cervical spine were analyzed using quantitative motion analysis software (Medical Metr...
Biomechanical studies on cervical total disc arthroplasty: A literature review
Clinical Biomechanics, 2008
Background. Many models of cervical disc prostheses are currently commercially available or under clinical trial, and are based on several design concepts and built employing different materials. This paper is targeted to the understanding of the possible relationships between the geometrical, mechanical and material properties of the various cervical disc prostheses and the restoration of a correct biomechanics of the implanted spine.
Update on cervical disc arthroplasty: where are we and where are we going?
Current Reviews in Musculoskeletal Medicine, 2008
Despite the very good results of anterior cervical discectomy and fusion, there are concerns of adjacent level degeneration. For this reason, interest has grown in the potential for motion sparing alternatives. Cervical disc arthroplasty is thus evolving as a potential alternative to fusion. Specific design characteristic and implants will be reviewed and outcomes summarized.
Cervical Disc Arthroplasty: An Overview of Past, Present and Future
Sinir Sistemi Cerrahisi Dergisi, 2015
Purpose of review: The present article reviews the most recent research into the rationale, patient selection, clinical results and complication profile of cervical arthroplasty. Recent findings: Recent results of prospective randomized control trials comparing cervical disc replacement and anterior fusion have demonstrated safety as well as equal or superior clinical results. In vivo kinematic studies have suggested decreased rates of adjacent segment disease following disc replacement. Increasingly, more studies are examining the complication profile and emerging contra-indications for cervical disc replacement. Summary: Cervical arthroplasty is a promising technique in that is undergoing rapid refinement and development. Further long-term data is eagerly awaited before the role in prevention of adjacent segment disease can be proven.
Historical review of cervical arthroplasty
Neurosurgical FOCUS, 2004
Early attempts at spinal arthroplasty in the 1950s yielded limited success. A revival of this procedure occurred in the 1980s and became a realistic treatment option in the 1990s. Both lumbar and cervical arthroplasties have been introduced in the US since 2000 for randomized, prospective studies in accordance with the Food and Drug Administration (FDA) investigational device exemption provisions. In June 2004 the first lumbar arthroplasty device was approved by the FDA for use in the US. It is likely that cervical arthroplasty will soon follow and may be available for widespread use as early as 2006. In this paper the authors review the historical development of cervical arthroplasty.

When surgically treating cervical degenerative disc disease, the most commonly performed procedure is anterior cervical discectomy. This procedure is performed with, or without fusion promoting methods. For both options the rate of fusion is high and there is much debate whether fusion of the treated segment is a contributing factor to accelerated degeneration of adjacent motion segments. In an effort to prevent degeneration of adjacent segments (ASDeg) due to loss of mobility at the operated level, cervical disc arthroplasty (CDA) was introduced. To evaluate the effectiveness of CDA in preventing ASDeg long term studies are necessary. However, prevention of ASDeg is based on the premise that mobile disc prostheses preserve cervical spine motion in a physiological way. In this article the authors describe a short term protocol for a study that aims to investigate whether CDA reaches the intended goal: restoration or preservation of physiological cervical spine motion. To this end, a...
PRESTIGE Cervical Arthroplasty: Past, Present, and Future
Seminars in Spine Surgery, 2012
Cervical arthroplasty was developed and is used to preserve segmental motion of the cervical spine for selected patients who require cervical diskectomy. There are now 3 cervical arthroplasty devices available for use in the United States. The data from the PRESTIGE ST US Food and Drug Administration Investigational Device Exemption trial and the relevant literature published on cervical arthroplasty devices were reviewed. The history of development, current clinical outcomes reports, and adverse events reports are summarized. Cervical arthroplasty is a safe and effective option for patients with single-level cervical disk disease with radiculopathy, who have normal facets. The appropriate inclusion and exclusion criteria for cervical arthroplasty from the US Food and Drug Administration trials must not be overlooked. Appropriate surgical technique will help optimize patient outcomes. Semin Spine Surg 24:14-19
Early clinical and biomechanical results following cervical arthroplasty
Neurosurgical Focus, 2004
Spinal arthroplasty may become the next gold standard for the treatment of degenerative cervical spine disease. This new modality must be studied rigorously to ensure in vivo efficacy and safety. The authors review the preliminary clinical experience and radiographic outcomes following insertion of the Bryan Cervical Disc Prosthesis (Medtronic Sofamor Danek, Memphis, TN). This prospective cohort study included 26 patients undergoing single- or two-level implantation of the Bryan artificial cervical disc for treatment of cervical degenerative disc disease resulting in radiculopathy and/or myelopathy. Radiographic and clinical assessments were made preoperatively 1.5, 3 months, and at 6, 12, and up to 24 months postoperatively. The Neck Disability Index (NDI) and Short Form-36 (SF-36) questionnaires were used to assess pain and functional outcomes. Segmental sagittal rotation from C2-3 to C6-7 was measured using quantitative motion analysis software. A total of 30 Bryan discs were pla...
Cervical disc arthroplasty: a critical review and appraisal of the latest available evidence
Advances and technical standards in neurosurgery, 2014
Anterior cervical discectomy and fusion (ACDF) has been a very successful procedure in the management of cervical radiculopathy and myelopathy. Concerns with adjacent segment disease and the desire to preserve physiological motion have led to technological and clinical efforts for cervical disc arthroplasty. The suggested move to cervical disc replacement has led to this latter procedure being one of the most scrutinised surgical treatments in the twenty-first century. Short- and medium-term prospective randomised clinical trials and systematic reviews show cervical disc replacement to be at least as good as ACDF as regards the clinical outcomes in the management of degenerative cervical spondylosis. This is logical since the neural decompression procedure is essentially the same. However, the rationale for arthroplasty over arthrodesis has been built on two main proposed roles: the preservation of segmental motion and the prevention of adjacent segment disease. Whilst results thus ...
