Popis: Degenerative disc disease and progressive sagittal malalignment can both contribute to degenerative cervical myelopathy and radiculopathy. For patients with symptoms refractory to conservative management, anterior cervical discectomy and fusion (ACDF) is a thoroughly-vetted intervention shown to improve pain and disability measures. Hyperlordotic implants can also help restore cervical sagittal balance through anterior column realignment (ACR).A consecutive bi-institutional series of patients who underwent ACDF with hyperlordotic polyetheretherketone (PEEK) implants between 2014-2016 was reviewed. All included patients underwent ACDF between C3-C7 inclusive of a hyperlordotic PEEK cervical implant (10° lordosis), and had ≥12-months of radiographic follow-up. Lateral radiographs were analyzed to compare pre- and postoperative cervical parameters.Forty-six patients were included (mean age, 58.0 years; male, 35%). Mean body mass index (BMI) was 28.3 kg/mOur study demonstrates that hyperlordotic PEEK implants used for ACR effectively contribute to restoration of cervical lordosis in patients undergoing ACDF, potentially reducing the need for additional posterior surgery.
