Anterior-only stabilization using cage versus plating with bone autograft for the treatment of type II/IIA Hangman’s fracture combined with intervertebral disc injury

摘要

BackgroundAnterior C2/3 discectomy and interbody fusion (ACDF) with plating is increasingly performed as the primary treatment of unstable Hangman’s fracture; however, plate-related complications, such as screw back-out, plate fracture and soft-tissue injury, is not uncommon. Polyetheretherketone (PEEK) cage has now been developed to provide initial stability before fusion; however, whether and how ACDF with PEEK cage offer better clinical results compared with ACDF with plating in management of Hangman’s fracture remains unknown. This study compares the efficacy of ACDF with plating to that of ACDF with PEEK cage in management of type II/IIA Hangman’s fractures (according to Levine and Edwards classification) retrospectively.
