Two-level cervical disc arthroplasty in patients with Klippel-Feil syndrome: A case report and review of the literature

摘要

Klippel-Feil syndrome (KFS) is defined by multiple abnormal segments of the cervical spine with congenital synostosis of two or more cervical vertebrae. KFS patients who demonstrate progressive symptomatic instability and/or neurologic sequelae are traditionally managed with operative decompression and arthrodesis.
