Abstract:BackgroundHybrid surgery (HS) combined cervical disc arthroplasty (CDA) with anterior cervical discectomy and fusion (ACDF) is emerging, but its biomechanical effects as a revision surgery (RS) on adjacent segments were unclear.ObjectivesThis finite element (FE) study aimed to investigate the biomechanical characteristics of HS to treat two‐level discontinuous ASD in ACDF RS.MethodsA C2‐T1 intact FE model was established and modified to a primary C5/6 ACDF model and five RS models. These RS models' segments C4… Show more
