Although the Mobi-C artificial disc and the ROI-C cervical cage have been widely used in the treatment of cervical degenerative disc diseases (CDDD), few reports addressed the features of combined application of both devices. This study is aimed at comparing the clinical and radiological outcomes of treating contiguous two-level CDDD using Mobi-C and ROI-C combined in a hybrid surgery (HS) with anterior cervical discectomy and fusion (ACDF) using ROI-C. We reviewed ninety-one patients who underwent HS (n = 48) or ACDF (n = 43) surgery for symptomatic contiguous two-level CDDD.

- The study examines the effectiveness of self-locking stand-alone cages for cervical fusion and identifies different fusion states at the index level among 42 patients over a 5-year follow-up period.
- The overall fusion rate was high at 97.4%, with type IV showing the highest fusion proportion, and all types demonstrated significant improvement in clinical outcomes.
- The research highlights the dynamic nature of the fusion process and suggests that factors like cage location and cervical spine alignment may influence the fusion state, but all types resulted in satisfactory clinical results.
Objective: To evaluate the intermediate and long-term follow-up effect of posterior dynamic lumbar stabilization in lumbar degenerative disease.
Methods: The clinical outcomes of 96 patients (male 51, female 45, age from 21 to 68 years, mean 41.5 years) whose follow-up time were more than 2 years with lumbar degenerative disease treated by posterior decompression with Wallis posterior dynamic lumbar stabilization implant or combined with posterior lumbar fusion from August 2007 to January 2010 were retrospectively studied, and assessed with visual analogue scale (VAS) and spinal operative standard of Chinese Medical Association.
