NuNec™ Cervical Disc Arthroplasty Improves Quality of Life in Cervical Radiculopathy and Myelopathy: A 2-yr Follow-up

Abstract

NuNec™ cervical disk arthroplasty improves quality of life in cervical radiculopathy and myelopathy: a two-year follow-up. AbstractBACKGROUND: Anterior cervical disk replacement is an alternative to fusion for the treatment of selected cases of radiculopathy and myelopathy. We report clinical and radiological outcomes after disk replacement with the NuNec™ artificial cervical disk with subgroup analysis. RESULTS: Forty-four NuNec™ disks were implanted in 33 patients. Clinical improvements were seen in all outcomes; significant improvements on the Neck Disability Index, Euroqol 5-dimensions and physical domain of the Short Form-36 were maintained at two years. There was a mean of 4 degrees range of movement at the replacement disk level at two years, a significant reduction from baseline; there was also progression in levels of heterotopic ossification.Complications included temporary dysphagia (10%) and progression of disease requiring foraminotomy (6%); no surgery for adjacent level disease was required. There was no significant difference in the outcomes of the radiculopathy and myelopathy groups.CONCLUSION: Clinical outcomes using the NuNec™ disk replacement are comparable with other disk replacements. Although range of movement is reduced, re-operation rate is very low. 2Short title: NuNec™ improves quality of life.

Single-Level Cervical Disc Replacement Using a PEEK-on-Ceramic Implant: Results of a Multicenter FDA IDE Trial With 24-Month Follow-up

“…4,5 Though less extensive than cervical fusion cages, there has been investigation into the use of PEEK for cervical TDR. [6][7][8][9][10][11][12] Despite general optimism, there was concern about long-term degradation on articulating PEEK-on-PEEK surfaces. 10 This may be particularly problematic and cause uneven loading if the implant is not ideally positioned.…”

Cervical Total Disc Replacement and Heterotopic Ossification: A Review of Literature Outcomes and Biomechanics

“…On the contrary, in studies with intermediate or longterm follow-up, ROM tends to significantly decrease in relation to preoperative ROM. Segmental ROM significantly decreased at 2-year [52,68], 4-year [85], >6-year [15], average 8-year [17], and average 10-year follow-up [86]. As the severity of HO and the incidence of ROMlimiting HO correlated with the length of the follow-up period [42,43], the formation of ROM-limiting HO may be accounted for the reduced ROM reported in clinical trials with intermediate to long-term follow-up.…”

“…Segmental ROM has been reported to decrease shortly after surgery and could persist up to 6-month follow-up in some studies [30,58,[64][65][66][67]. Factors that might have led to the decrease in segmental ROM reported in the studies include the following: (1) the cohort of subjects has greater impairment in ROM preoperatively [68]; (2) fear of moving the neck to the extremes of flexion and extension during dynamic X-ray; (3) and postoperative neck pain [30]. However, in longer term follow-up, ROM became comparable to preoperative values [30,58,[64][65][66][67].…”
