Fig. 6From: Adjacent-level biomechanics after single-level anterior cervical interbody fusion with anchored zero-profile spacer versus cage-plate construct: a finite element studyIntradiscal stress distribution features of C4-C5 and C6-C7 segments in the intact model, Zero-P model and PCC model in flexion, extension, axial rotation and lateral bending conditions. The colour changes from red to deep blue represent the stress variation from large to small on the stress nephogramBack to article page
