Posterior instrumentation and fusion (scoliosis)

Last revised by Henry Knipe on 23 Aug 2021

Posterior instrumentation and fusion is a surgical technique to improve spinal curvature in scoliosis patients.


The vertebral column is manipulated into the desired position and held in place with metalwork namely pedicle screws and/or hooks transfixed with rods with or without in situ contouring 1. Bone graft material is then placed over the posterior elements. Thoracoplasty may or may not be performed 2

Compared to the anterior approach, a posterior approach has a simpler surgical exposure and greater sagittal control 1
