Posterior Cervical Fusion In Posterior View

Description

Seen from a posterior neck approach, the animation centers on the subaxial cervical spine with adjacent vertebrae aligned from C2 toward C7, their spinous processes in the midline and laminae forming the posterior arch. Metallic posterior instrumentation spans the motion segment, with lateral mass or pedicle screw heads positioned lateral to the spinous processes and linked by longitudinal rods that track inferiorly on each side. As the sequence progresses, hardware seats onto bone and the construct tightens, conveying how the implants convert multiple vertebrae into a single stabilized unit. Midline symmetry and left-right screw-rod alignment remain the dominant visual landmarks. Posterior cervical fusion is a workhorse operation for instability and deformity, and for decompressive procedures that would otherwise leave the cervical spine prone to progressive kyphosis. The animated build-up of the construct clarifies load sharing in a way a static plate-and-screw portrait cannot: you see how screw purchase in the lateral masses (or pedicles in selected levels) couples to rod contouring to restore alignment while limiting flexion, extension, and rotation. That mechanical story matters when teaching adjacent segment disease, pseudarthrosis, and hardware failure patterns such as rod fracture or screw pullout after poor bone quality or suboptimal trajectory. Use this animation in neurosurgery and orthopedic spine teaching on posterior approaches, instrumentation basics, and postoperative imaging correlation, where learners must map rod and screw position to expected findings on lateral radiographs and CT. It also fits procedure overviews for patient education, device documentation, and publisher diagrams illustrating posterior stabilization of the cervical spine.
