Randomized Controlled Trial Multicenter Study
The Norwegian Cervical Arthroplasty Trial (NORCAT): 2-year clinical outcome after single-level cervical arthroplasty versus fusion-a prospective, single-blinded, randomized, controlled multicenter study.
Standard surgical treatment for symptomatic cervical disc disease has been discectomy and fusion, but the use of arthroplasty, designed to preserve motion, has increased, and most studies report clinical outcome in its favor. Few of these trials, however, blinded the patients. We, therefore, conducted the Norwegian Cervical Arthroplasty Trial, and present 2-year clinical outcome after arthroplasty or fusion. ⋯ The present study showed excellent clinical results and no significant difference between treatments at any scheduled follow-up. However, the rate of index level reoperations was higher and the duration of surgery longer with arthroplasty.

Review Case Reports
Management of destructive Candida albicans spondylodiscitis of the cervical spine: a systematic analysis of literature illustrated by an unusual case.
Candida induced spondylodiscitis of the cervical spine in immunocompetent patients is an extremely rare infectious complication. Since clinical symptoms might be nonspecific, therapeutic latency can lead to permanent spinal cord damage, sepsis and fatal complications. Surgical debridement is strongly recommended but there is no standard antimycotic regime for postsurgical treatment. This paper summarizes available data and demonstrates another successfully treated case. ⋯ Candida albicans spondylodiscitis of the cervical spine presents a potentially life-threatening disease. To our knowledge, this is the fifth case in literature that describes the treatment of C. albicans spondylodiscitis in an immunocompetent patient. Surgical debridement has to be considered, following antimycotic regime recommendations vary in pharmaceutical agents and treatment duration.

To identify whether expansive open-door laminoplasty (Lam) is more appropriate than laminectomy and instrumented fusion (LIF) for cases with ossification of the posterior longitudinal ligament (OPLL) and straight cervical lordosis. ⋯ When compared with the LIF, the Lam is recommended for cases with OPLL and straight cervical lordosis when taking comparable neurological recovery, less axial pain and better neck function improvement into consideration.

Thoraco-lumbo-sacral orthosis (TLSO) is an effective treatment in adolescent idiopathic scoliosis (AIS) patients, but cervical sagittal alignment (CSA) variations after bracing have never been evaluated. The purpose of this study was to assess changes in CSA before, during and after TLSO treatment, and to determine whether patients developed cervical pain. ⋯ The TLSO can control progression of the deformity in the frontal plane, but it influences CSA, TSA and LSA. In particular, it decreases cervical spine lordosis, with reduction maintained 1 year after the end of treatment. Numerical differences, although statistically significant, were not clinically relevant.

Hybrid surgery (HS) coupling total disc replacement and fusion has been increasingly applied for multilevel cervical disc diseases (CDD). However, selection of the optimal disc prosthesis for HS in an individual patient has not been investigated. This study aimed to distinguish the biomechanical performances of five widely used prostheses (Bryan, ProDisc-C, PCM, Mobi-C, and Discover) in HS for the treatment of bi-level CDD. ⋯ Each disc prosthesis has its biomechanical advantages and disadvantages in HS and should be selected on an individual patient basis. In general, ProDisc-C, Mobi-C, and Discover produced similar performances in terms of spinal motions, adjacent IDPs, and driving moments, whereas Bryan and PCM produced similar biomechanical performances. Therefore, HS with Discover, Bryan, and PCM may be suitable for patients with potential risk of facet joint degeneration, whereas HS with ProDisc-C, Mobi-C, and Discover may be suitable for patients with potential risk of vertebral osteoporosis.
