Comparative Study of Functional Outcome of Anterior Cervical Decompression and Interbody Fusion With Tricortical Stand-Alone Iliac Crest Autograft Versus Stand-Alone Polyetheretherketone Cage in Cervical Spondylotic Myelopathy:

Study Design:Retrospective analysis of prospectively collected data.Objective:The aim of the study was to compare the outcome of anterior cervical decompression and fusion (ACDF) with stand-alone tricortical iliac crest autograft versus stand-alone polyetheretherketone (PEEK) cage in cases of cervical spondylotic myelopathy.Methods:Prospectively collected data of 60 patients in each group were compared.Results:There was statistically significant improvement noted in postoperative Modified Japanese Orthopaedic Association (MJOA) follow-up scores with comparison pairs of preoperative versus 6 months, preoperative versus 1 year, and 3 months versus 6 months, 3 months versus 1 year in both groups. But improvements in MJOA scores were statistically insignificant between 6 months and 1 year (P = .0639) for the autograft group when compared with PEEK cage group (P = 0001). The mean loss of segmental lordosis on follow-up X-ray for the autograft group was (5.89 ± 2.90°), which was significantly higher (1.88 ± 2.7...
