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.

Multicenter Study
Early versus delayed reduction of cervical spine dislocation with complete motor paralysis: a multicenter study.
Reduction of cervical facet dislocation should be performed as soon as possible to depressurize neuron cells although some randomized control studies defined early reduction as over 24 h after trauma. The purpose of this study was to define the actual time limit for early reduction in patients with complete motor paralysis. ⋯ Our data suggest that early (<6 h) reduction of cervical spine dislocation is associated with favorable neurological outcome as compared with those performed after 6 h.
