The Use of External Fixation for the Management of the Unstable Anterior Pelvic Ring

The objective of this article was to highlight the indications and various methods of external fixation for management of the unstable anterior pelvic ring. Although most often used temporarily in the setting of significant hemorrhage from a pelvic ring fracture, external fixation remains an option for definitive stabilization of select pelvic ring injuries. Classically, the iliac crest frame has been used, although use of the supra-acetabular frame has gained favor due to its superior bone purchase and improved biomechanics. Common complications from external fixation include pin site infections, loss of reduction, and the "external fixator deformity."
