Comparison of Polyetheretherketone (PEEK) Cage versus Iliac Bone Graft undergoing Anterior Cervical Discectomy and Fusion (ACDF): A multicenter experience

Background:In anterior cervical discectomy and fusion (ACDF), the two most frequently used materials are allografts polyetheretherketone (PEEK) cages. The aim of study was to compare functional radiological outcomes cages with iliac crest in decompression (ACDF) patients symptomatic Cervical spondylotic myelopathy (CSM).Methods:In this cohort study, we included 70 (35 each group) CSM having degenerative disc disease who were planned for ACDF from Jan-2017 Jan-2021 Rawalpindi Medical University. All procedures performed under general anesthesia supine position, standard technique all patients. Anterior locked plates fixation PEEK or inter-vertebral space. Radiologic determined till 6 months after surgery. Results:The baseline characteristics similar between groups. Mean Modified Japanese Orthopaedic Association (MJOA) score at 06 months’ follow-up same groups; 14.16±4.30 group A 13.54±3.24 B (p-value 0.49). Disc space height also 10.01±0.67 mm versus 10.11±0.70 0.54). Fusion rate final 31 (88.6%) 30 (85.7%) 0.72).Conclusion:PEEK have radiologic comparison ileal allografts. So, can be as a successful alternative will help reduce donor site morbidity longer surgical times associated graft harvesting.
