BACKGROUND CONTEXT Adjacent segment degeneration (ASD) after cervical fusion is a clinical concern. Despite previous studies documenting the biomechanical effects of multilevel cervical fusion on segments immediately superior and inferior to the operative segments, the pathogenesis of the initiation of degeneration progression in neighboring segments is still poorly understood. PURPOSE To test the hypothesis that changes in range of motion, disc stresses, and facet loads would be highest at… CONTINUE READING
