Abstract
BACKGROUND: Anterior cervical discectomy and fusion (ACDF) is a common surgery for patients with degenerative cervical disease and current interbody spacers utilized vary based on material composition, structure, and angle of lordosis. Currently, there is a lack of literature comparing subsidence rates or long-term radiographic outcomes with hyperlordotic and standard lordotic spacers. This study compares long-term radiographic outcomes, subsidence rate, and rate of fusion in patients who underwent ACDF with hyperlordotic or standard interbody placement.
MATERIALS AND METHODS: Patients who underwent 1-3-level ACDF with either a standard lordosis or hyperlordotic interbody were included. Standard radiographs were evaluated for C2-7 lordosis (CL), sagittal vertical axis, C2 slope (C2S), T1 slope (T1S), subsidence rate, and fusion.
RESULTS: Forty-five patients underwent ACDF with hyperlordotic interbody placement and after a 1:1 propensity match with standard lordotic patients, 90 patients were included. 1-year postoperative radiographs demonstrated the hyperlordotic cohort achieved higher CL (15.3° ± 10.6° vs. 9.58° ± 8.88°;
CONCLUSION: Hyperlordotic spacer placement in ACDF can provide increased CL compared to standard lordosis spacers, which can be considered for patients requiring restoration or maintenance of CL following ACDF.
