Scolisosis Surgery Results, Posterior View

Description

Posterior elements of the thoracic and lumbar vertebral column are centered around a corrected midline, with bilateral steel rods spanning multiple motion segments and tracking parallel to the spinous processes from superior to inferior levels. Paired pedicle screw heads and connecting hardware sit lateral to the midline at each instrumented vertebra, aligning with the pedicles and posterior arches, while the laminae and spinous processes remain visible between the implants. Coronal alignment reads as a near-vertical column, with reduced lateral deviation and a more symmetric relationship of the vertebral bodies to the posterior midline landmarks. Hardware dominates the paraspinal corridor. Correction of adolescent idiopathic scoliosis and adult degenerative scoliosis is often achieved through posterior spinal fusion with segmental instrumentation, where rods and pedicle screws translate and derotate the deformity while maintaining spinal balance. The posterior perspective is the one surgeons use when discussing midline exposure, screw trajectory, and rod contouring, so seeing the implants relative to the spinous processes and pedicle lines helps frame concepts like coronal decompensation, shoulder or pelvic tilt, and junctional level selection. Straightness alone is not the endpoint. The illustration’s emphasis on symmetric rod placement and restored verticality supports teaching of postoperative goals and common checks on immediate postoperative radiographs. Use this illustration in orthopedic and neurosurgical education on posterior spinal instrumentation, in publisher diagrams accompanying chapters on scoliosis treatment, and in clinic-facing materials that explain what rod-and-screw constructs look like after corrective fusion.
