简要总结
Subsidence of cervical cages is a common problem. For the study, a new polyacrylmethacrylate cage was designed and prospectively implanted in patients with a mono- or bilevel cervical pathology. As control, a commercially available PEEK-cage was used, patients were randomized using minimization randomization, controlling for age and bone mineral densitiy. The investigators hypothesize that the newly developed cage has similar clinical and radiological qualities compared to the PEEK-cage, but at a much more favourable cost-performance ratio.

结局指标
主要结局
Clinical outcome (NDI)
时间窗: 12 months postoperative
NDI (Neck disability index) will be measured prior to surgery and 12 months after surgery. A difference of 20% between both groups is considered to be clinically significant, which is proposed for the experimental implant (PMMA-cage).
次要结局
- Clinical outcome (VAS-neck), Subsidence(12 months postoperative)
