Lumbar Corpectomy And Fusion, Posterior View

Description

Posterior lumbar exposure frames the spinous processes and laminae with the pedicles flanking the vertebral canal, while the animation steps through corpectomy-level stabilization using posterior instrumentation. Pedicle screws seat bilaterally into adjacent vertebrae, connected by longitudinal rods that run craniocaudally and sit posterolateral to the removed vertebral body segment. As the sequence progresses, a vertebral body replacement implant (cage) occupies the corpectomy defect anterior to the spinal canal, and compression across the rods tensions the construct to restore sagittal alignment and load sharing across the fusion segment. Screw trajectories and rod contouring are shown in relation to the facet joints and transverse processes. Clear landmarks. This procedure matters when vertebral body integrity fails, most commonly after burst fracture, osteomyelitis with collapse, or tumor resection, where decompression and anterior column reconstruction must be paired with rigid posterior fixation. Animation clarifies what static plates cannot: the order of hardware placement, the way rod capture and set-screw tightening translate into segmental reduction, and how a cage supports the anterior column while the posterior construct controls translation and rotation. It also helps explain why pedicle breach risks nerve root or dural injury, and why construct length changes with bone quality and junctional demands. Use this clip in spine surgery teaching for posterior thoracolumbar instrumentation, operative technique atlases describing corpectomy and fusion, and patient-facing counseling that needs an honest view of implanted hardware and its anatomic neighborhood. It also fits radiology or orthopedics modules that correlate postoperative CT or fluoroscopic appearance with the actual implant geometry and screw-rod layout.
