- W2894885899 abstract "BACKGROUND CONTEXT Cervical malalignment has been associated with increased disability. Both cSVA and C2S have been correlated to poor clinical outcomes. Surgical corrections of severe cervical deformities present considerable treatment challenges. Demographic, surgical and postoperative factors associated with failed radiographic and clinical outcomes have not been well established. PURPOSE To identify patients at risk of failure to restore sagittal alignment in cervical deformity corrective surgery. Additionally, to analyze how failure to restore sagittal alignment postoperatively affects patient reported outcomes and to determine the clinical significance of failure to correct malalignment. STUDY DESIGN/SETTING Retrospective review of a prospective cohort of consecutively enrolled cervical deformity patients. PATIENT SAMPLE Sixty-six patients with severe cervical deformity at baseline (defined as>4 cm cSVA or >20°C2 slope) with one year radiographic follow-up. OUTCOME MEASURES Postoperative sagittal alignment parameters, health-related outcome measures, and surgical parameters. METHODS A prospective database of operative CD patients (inclusion criteria: cervical kyphosis >10°, cervical scoliosis >10°, cSVA>4 cm or CBVA>25°) was analyzed. Inclusion was restricted to severe baseline cervical deformities (cSVA>4 cm or C2 Slope (C2S)>20°) and 1-year follow-up. Failed surgery was defined as cSVA>4 cm at 1 year while successful surgery was defined as cSVA 7). RESULTS Sixty-six patients with severe CD met inclusion criteria, including 41 failed (62%) surgery and 25 successful. Failed surgery patients had worse sagittal alignment at baseline and 1 year by cSVA, C2S, T1S, TS-CL, and CTPA (p CONCLUSIONS Baseline cervical malalignment, male gender and intra-operative blood loss were associated with failed radiographic outcomes in patients with severe cervical deformity. Failed surgery patients also had less improvement in NDI at 6 months and 1 year than successful surgeries. More patients with successful surgeries attained MCID for NDI at 6 months. In correcting severe CD, surgeons need to obtain optimal radiographic alignment to attain better clinical outcomes.
