BACKGROUND: This study aimed to investigate whether cervical disc arthroplasty (CDA) would be equally effective in elderly patients as in the young. The inclusion criteria of published clinical trials for CDA-enrolled patients covered the ages from 18 to 78 years. However, there was a paucity of data addressing the differences of outcomes between older and the younger patients. METHODS: A series of consecutive patients who underwent one- or two-level CDA were retrospectively reviewed...

BACKGROUND CONTEXT: Surgery for cervical degenerative disc disorder (CDDD) at two noncontiguous segments is infrequent. Few studies have explored the biomechanical effects on the intermediate adjacent segment of anterior cervical discectomy and fusion (ACDF) or cervical disc arthroplasty (CDA) in this situation. No study has examined biomechanical differences between ACDF and hybrid surgery (HS) constructs for noncontiguous CDDD. Differences in the biomechanical changes between the intermediate and adjacent segments are unknown...

BACKGROUND: Moderately increased motion at the intermediate segment (IS) after skip-level fusion may accelerate disc degeneration. However, limited biomechanical data are available that examine the effects on the IS following cervical disc arthroplasty (CDA). The purpose of this study is to investigate the biomechanical changes in the IS of the cervical spine after skip-level fusion or skip-level arthroplasty. METHODS: A finite element model of a healthy cervical spine (C2-C7) was constructed...

BACKGROUND: Cervical fusion is associated with adjacent segment degeneration. Cervical disc arthroplasty is considered an alternative to reduce risk of adjacent segment disease. Kinematics after arthroplasty should closely replicate healthy in vivo kinematics to reduce adjacent segment stresses. The purpose of this study was to assess the kinematics of a polycrystalline diamond cervical disc prosthesis. METHODS: Nine cadaveric C3-T1 spines were tested intact and after one (C5-C6) and two level (C5-C7) arthroplasty (Triadyme-C, Dymicron Inc...

INTRODUCTION: Cervical disc arthroplasty (CDA) was developed to decrease the rate of symptomatic adjacent-level disease while preserving motion in the cervical spine. METHODS: The objectives of this paper are to provide criteria for proper patient selection as well as to present a comprehensive literature review of the current evidence for CDA, including randomized studies, the most recent meta-analysis findings, and long-term follow-up clinical trials as well. RESULTS: Currently, there are several prospective randomized controlled studies of level I of evidence attesting to the safety and efficacy of CDA in the management of cervical spondylotic disease (CSD) for one- or two-level degenerative diseases...

Two major forms of physician reimbursement include Medicare (MCR; federally funded) and Medicaid (MCD; state funded). The only oversight provided to individual states for setting MCD reimbursement is that it must provide a standard payment that does not negatively affect patient care. The goals of this study were to determine the variability of MCD reimbursement for patients who require orthopedic procedures and to assess how this compares with regional MCR reimbursement. Medicaid reimbursement rates from each state were obtained for total knee arthroplasty, total hip arthroplasty, anterior cruciate ligament repair, rotator cuff repair, anterior cervical decompression and fusion, posterior lumbar decompression, carpal tunnel release, distal radius open reduction and internal fixation, proximal femur open reduction and internal fixation, and ankle open reduction and internal fixation...

Over the last decade, several of the Food and Drug Administration-regulated investigational device exemption (IDE) trials have compared multiple cervical disk arthroplasty (CDA) devices to anterior cervical decompression and fusion (ACDF) showing comparable and even superior patient-reported outcomes. CDA has been an increasingly attractive option because of the positive outcomes and the motion-preserving technology. However, with the large burden that health care expenditures place on the economy, the focus is now on the value of treatment options...

BACKGROUND: Motion preserving anterior cervical disc arthroplasty (ACDA) in patients with cervical radiculopathy was introduced to prevent symptomatic adjacent disc degeneration as compared with anterior cervical discectomy and fusion (ACDF). Prior reports suggest that ACDF is not more effective than anterior cervical discectomy (ACD) alone for the treatment of cervical radiculopathy. PURPOSE: To evaluate whether patients with cervical radiculopathy due to a herniated disc benefit more from undergoing ACDA, ACDF, or ACD in terms of clinical outcome measured by the neck disability index (NDI)...

Background: Due to increased postoperative complications with anterior cervical discectomy and fusion (ACDF), there has been an increasing interest in the use of cervical disc arthroplasty (CDA). Advancements in prosthetic designs and techniques have improved patient reported outcome measurements and minimized revision rates. There is a paucity in the literature regarding recent trends in CDA utilization and revision rates. The purpose of this study was to determine annual primary and revision CDA trends with the use of an administrative database...

Cervical disc arthroplasty (CDA), or total disc replacement, has emerged as an option in the past two decades for the management of 1- and 2-level cervical disc herniation and spondylosis causing radiculopathy, myelopathy, or both. Multiple prospective randomized controlled trials have demonstrated CDA to be as safe and effective as anterior cervical discectomy and fusion, which has been the standard of care for decades. Moreover, CDA successfully preserved segmental mobility in the majority of surgical levels for 5-10 years...

BACKGROUND: Cervical Total Disc Arthroplasty (TDA) or cervical artificial disc replacement (C-ADR) is an alternative technique to anterior cervical discectomy and fusion (ACDF) for the treatment of symptomatic degenerative cervical spine disease. The main goal of TDA is to maintain cervical motion and therefore lower the risk of adjacent levels' deterioration. Granuloma formation on a cervical TDA is exceptional. We report such a case. CLINICAL PRESENTATION: A 48-year-old female suffering from left cervico-brachialgia underwent a double-level TDA (SpinalKinetics® M6-C Artificial Cervical Disc) on C5-C6 and C6-C7 in another hospital in 2010...

PURPOSE: Cervical disc herniation is a common pathology. It can be treated by different surgical procedures. We aimed to list and analyzed every available surgical option. We focused on the comparison between anterior cervical decompression and fusion and cervical disc arthroplasty. RESULTS: The anterior approach is the most commonly used to achieve decompression and fusion by the mean of autograft or cage that could also be combined with anterior plating. Anterior procedures without fusion have shown good outcomes but are limited by post-operative cervicalgia and kyphotic events...
