Anatomy of the sacrum

Abstract

One of the basic tenets of performing surgery is knowledge of the relevant anatomy. Surgeons incorporate this knowledge along with factors, such as biomechanics and physiology, to develop their operative approaches and procedures. In the diagnosis and management of sacral tumors, the need to be familiar with the anatomy of the sacrum is no less important than knowledge of the pathological entity involved. This article will provide an overview of the embryology and anatomy of the sacrum, along with concepts as applied to surgical intervention.
