Posterior Cervical Fusion And Instrumentation, Lateral View

Description

Posterior cervical instrumentation spans the mid to lower cervical spine in a lateral profile, with paired longitudinal rods tracking the normal cervical lordotic curvature and secured by multiple screw heads aligned over the posterior elements. Pedicle screws, and in some constructs lateral mass screws, sit posterior to the vertebral bodies with their trajectories directed anteriorly toward the pedicles, while the connecting rods remain superficial to the laminae and spinous processes. Screw tulips and set screws form a repeating series of fixation points along the construct, emphasizing level-to-level alignment from a cephalad to caudad direction. Bony landmarks of the posterior cervical column frame the hardware. Nothing is ambiguous. Posterior cervical fusion and instrumentation is the workhorse solution for multilevel cervical spondylotic myelopathy, post-laminectomy instability, trauma, and deformity correction when anterior fixation alone is insufficient, and the lateral perspective is the most practical way to communicate sagittal balance, junctional transitions, and hardware contouring. By placing the rods against the cervical curvature in a single consistent profile, the illustration makes it easier to discuss how inadequate lordosis or malpositioned screws can concentrate stress at the cranial or caudal end of the construct and contribute to screw loosening, rod fatigue fracture, or adjacent segment degeneration. Attention to the relationship between the posterior hardware and the underlying vertebral bodies also supports teaching safe corridors, where a medial breach risks the spinal canal and a lateral breach threatens the vertebral artery in the transverse foramen. Spine surgery atlases, orthopedic and neurosurgical lectures, and radiology teaching files can use this illustration to label posterior fixation components and relate them to postoperative lateral cervical radiographs and CT reconstructions. It also fits patient-facing surgical consent materials that need a precise, non-technical visual of rods and screws without sacrificing anatomical fidelity.
