Anterior cervical discectomy and fusion with ROI-C peek cage: cervical alignment and patient outcomes

Abstract

This is the first prospective study on ROI-C cages. Although this is a preliminary assessment, the ROI-C cage may represent an excellent alternative to other devices or simple bone graft.

A comparison of anterior cervical discectomy and fusion (ACDF) using self-locking stand-alone polyetheretherketone (PEEK) cage with ACDF using cage and plate in the treatment of three-level cervical degenerative spondylopathy: a retrospective study with 2-year follow-up

“…Biomechanical studies have revealed that the self-locking stand-alone cage provides less stiffness of cervical spine as locking plate does in 2 or 3-level instrumentation [14,15]. But high fusion rate can be achieved using these kinds of cages for the treatment of single-level, double-level, and even three-level cervical spondylopathy (Table 3) [7][8][9][10][16][17][18]. In our study, the nonunion rate was not statistically significant between groups [4.3 % (4/28) vs 7.7 % (2/26)] (P = 0.736).…”

“…The function of anchoring clips is considered to be similar to a plate and screws, offering immediate stabilization after surgery [7]. Studies have also shown that this kind of cages can effectively restore cervical lordosis, and obviate the platerelated complications, as compared to ACDF using cages and plate fixation for single or double-level cervical spondylopathy [7][8][9]. Further, a non-comparative study has reported satisfactory clinical efficacy and radiological outcomes with the three-level ACDF using this kind of PEEK cages [10].…”

Comparison of the clinical effects of zero-profile anchored spacer (ROI-C) and conventional cage-plate construct for the treatment of noncontiguous bilevel of cervical degenerative disc disease (CDDD)

“…[ 10 , 11 ] A ROI-C device (LDR, Troyes, France) of the cervical spine was developed and used clinically in single-level, double-level, or even in multilevel CDDD to overcome these disadvantages. [ 12 – 16 ]…”

A Comparison Of The Bridge-Type Roi-c Interbody Fusion Cage System And Titanium Mesh Graft With Titanium Plate Fixation In 2-Level Anterior Cervical Discectomy And Fusion With Plating And Cage System: A Retrospective Study

“…Only after bone fusion can kyphosis and spinal canal stenosis be effectively prevented, so as to prevent compression of spinal cord and nerve root [20] . Wang et al [ 21] and Grasso et al [ 22] reported a fusion rate of 100% in patients with ROI-C who were followed up for 2 years.…”
