Surgical Anatomy of the Sacral Spine

Abstract

Posterior approach and fixation technique of the lumbosacral spine are commonly used for the treatment of severe spinal diseases. To provide a rigid construct, it’s often required to perform internal fixation in the sacrum and ilium in the treatment of severe scoliosis, lumbar vertebral slippage, tumor metastasis, infections, degeneration, or traumas. Pedicle screw fixation of S1 is the most commonly used technique, and internal fixation with iliac screws should also be taken into consideration when necessary. Mastering the anatomical and morphological knowledge about the sacrum is a key precondition for a successful operation.
