We investigated the effectiveness of a new material, polyetheretherketone (PEEK), in a spinal cage used in performing cervical spinal fusion for the correction of cervical kyphosis. ⋯ The PEEK cage provides solid fusion, increased cervical lordosis, and increased height and cross sectional area of the foramina. There are few complications associated with the use of this cage, and the functional and neurological outcomes are satisfactory. It also facilitates postoperative x-ray and magnetic resonance imaging evaluation. The PEEK cage is therefore a good substitute for AICG fusion in patients with cervical disc disease.
