Liu W, et al. - In patients who underwent anterior cervical discectomy fusion with self-locking stand-alone polyetheretherketone cage, the role of cervical sagittal alignment in the occurrence of adjacent-level ossification development (ALOD) was investigated. Researchers also assessed the relationship between cervical sagittal alignment and clinical outcomes. Analyzing 118 adults who had the procedure done for cervical radiculopathy or myelopathy between December 2013 and December 2015, they identified 2 groups of patients: 15 patients developing ALOD and 103 patients not developing ALOD. Observations revealed a lower risk of ALOD and improved clinical outcomes in association with maintaining a lordotic cervical sagittal alignment.
