The Effect of Sacral Fracture Malreduction on the Safe Placement of Iliosacral Screws

Abstract

Although previous authors have accepted up to 15 mm of cranial displacement, the data demonstrate substantial compromise of available screw space with displacements greater than 1 cm. Fracture reduction is mandatory, as screw placement with residual displacement of 10 mm or more can endanger adjacent neural and vascular structures.
