Abstract
INTRODUCTION: Subsidence is an incapacitating complication in Anterior cervical discectomy and fusion (ACDF). However, the debate over which of the intervertebral devices is associated with lower incidence of subsidence remains to be settled.
METHODS: Seven dominant techniques including cage with plate (CP), iliac bone graft with plate (IP), Zero-profile cage with screws (Zero-P), ROI-C cages with clips (ROI-C), PEEK cage alone (PCA), iliac crest autogenous graft (ICAG) and titanium cage alone (TCA) were examined. The incidences of subsidence in the different groups were calculated and compared.
RESULTS: A total of 30 studies with 2264 patients were identified. Overall, the CP group presented the lowest incidence of subsidence, and its incidence was significantly lower than that in the Zero-P group, the PCA group, the ICAG group and the TCA group (P<0.05). The incidence of subsidence in the IP group was significantly lower than that in the PCA group, the ICAG group and the TCA group (P<0.05). In single-level ACDF, the CP group presented the lowest incidence of subsidence, and its incidence was significantly lower than that in the PCA group and the TCA group (P<0.05). No difference was found between single-level and multilevel ACDF. And the incidence of subsidence was higher in those undergoing single-level ACDF.
CONCLUSION: CP and IP resulted in a lower rate of subsidence than cage alone or ICAG. Zero-p and ROI-C cages lead to similar subsidence rate with plate. All types of intervertebral device can be applied to both single-level and multilevel ACDF with comparable subsidence rate.
