Biomechanics of Sacral Fixation

  • J. C. Y. Leong
  • W. W. Lu


The wedge-shaped sacrum not only gives support to the vertebral column, it also provides strength and stability to the pelvis. Recent renewed interest in sacral screw fixations together with advancements in mechanical understanding have resulted in increased attention being paid to the surgical anatomy of the sacrum [1–5]. Awareness of the anatomical structure, and the adjacent neurovascular and visceral structures and their configurations will minimize complications and contribute to a successful surgical outcome.
