Background: Cervical spine stenosis is one of the most common degenerative changes of cervical spondylotic myelopathy (CSM) and results in severe dysfunction of the cervical spinal cord. The conventional treatment of such degenerative cervical spine conditions is anterior cervical discectomy and fusion (ACDF). Strut graft remains the gold standard in ACDF with excellent patient recovery but has many shortcomings. Polyetheretherketone (PEEK) cages have recently become popular as a replacement for strut grafts in patients undergoing ACDF.
Objective: This study was carried out to compare the clinical and radiographic outcomes of autologous bone grafts versus PEEK cages in patients undergoing ACDF surgery.
Materials and Methods: It was a randomized controlled trial conducted at the Neurosurgery Department Punjab Institute of Neurosciences for three years. Patients who consented to be a part of this study and fulfilled our predefined inclusion criteria were recruited and randomized into 2 groups. One group underwent ACDF with auto bone graft whereas the other group underwent ACDF with PEEK cage.
Results: A total of 198 subjects were included in this study. The mean age was calculated as 47.60 ± 9.17 years in the PEEK cage group and 46.74 ± 8.87 years in the Autologous bone graft group. Males accounted for 59.6% of the study population. The fusion rate was found to be higher in the PEEK cage group with a p-value of 0.002.
Conclusion: PEEK cages are superior to strut grafts as they have lesser morbidity after ACDF surgery in patients with CSM.
