Aim. The aim of this retrospective clinical and radiographic study was to provide follow-up data on the surgical success and patient outcome of polyetheretherketone (PEEK) cage-assisted anterior cervical discectomy and fusion (ACDF) at four levels. The literature on four-level ACDF is scanty, and the reported series are not enterely comparable because of differences in patient characteristics, types of spinal arthrodesis, and methods for quantitating outcome.
Methods. During the period between January 2003 and January 2005 10 patients (3 males and 7 females, with a mean age of 54.9 years) suffering from cervical myeloradiculopathy due to compressive spondylosys from C3-C4 to C6-C7 underwent PEEK cage-assisted ACDF at four levels.
Results. No intra- or postoperative complications were noted. The follow-up period ranged from 12 to 24 months (mean 15.8 months). The NCSS score was 9.2±1.48 preoperatively and 12.7±0.67 at follow-up examination (P<0.05). Preoperatively, the curvature, range of motion (ROM), and height of the foramina of the cervical spine were 16.9±5.84°, 27.6±3.5°, and 8.1±2.33 mm respectively, whereas at follow-up evaluation they were 19.5±7.03° (P>0.05), 22.2±3.43° (P<0.05), and 10.6±1.71 mm (P<0.05) respectively. None of the patients showed pre- or postoperative cervical instability. The fusion rate was 97.5%.
Conclusion. PEEK cage-assisted ACDF at four levels is an effective procedure for the treatment of patients with spondylotic compression of the spinal cord and/or nerve roots from C3-C4 to C6-C7.
