Lumbar Corpectomy And Fusion In Anatomical View

Description

Mid-lumbar spine anatomy is presented in an anatomical orientation as a corpectomy proceeds through sequential steps: discectomy at the adjacent intervertebral levels, removal of the vertebral body, and placement of a structural cage in the resulting defect. Superior and inferior vertebral endplates define the cranial and caudal boundaries, while the posterior vertebral wall lies immediately anterior to the spinal canal and its dural sac. The animation tracks how the cage seats centrally between endplates to restore anterior column height, then follows the construct as fusion is established across the segment with graft material and stabilization hardware as indicated. Corpectomy in the lumbar column is a workhorse operation for burst fracture with vertebral body comminution, vertebral osteomyelitis, primary or metastatic tumor, and severe deformity when posterior-only decompression cannot address anterior column compromise. Seeing the vertebral body removed in layers clarifies why the posterior cortex and pedicles are treated as high-risk boundaries, and how under-prepared endplates predispose to cage subsidence and recurrent kyphosis. Motion in the sequence makes load transfer intuitive: height restoration tensions the annulus and longitudinal ligaments, while final fixation reduces micromotion that would otherwise block arthrodesis. A high-stakes corridor. Use this animation for spine surgery teaching on anterior column reconstruction, for neurosurgery and orthopedic modules on decompression and fusion biomechanics, and for patient education when explaining why a cage replaces a diseased vertebral body rather than a simple discectomy. It also supports textbook chapters and conference presentations comparing corpectomy to posterior vertebral column resection or short-segment fixation in trauma.
