Beaming the Charcot Foot

Abstract

The Charcot diabetic foot presents unique challenges to the podiatric surgeon in the quest to salvage the limb. This disorder is an intersection of prototypical metabolic diseases and neurodegenerative disorder. Furthermore, it can be considered a disease of bone and ligaments that is often complicated by peripheral vascular disease and serious deep infection. Presently, simplistic ablative surgical procedures and the brace-makers art, still have a valid place in treating this disorder. Newer methods of surgical reconstruction are rapidly evolving to address distorted and nonfunctional limb. This article seeks to evidence the principles and practice of beaming the Charcot midfoot. As will be presented, the beam is a load-sharing device, which can be surgically introduced in an intramedullary method to restore architecture and strength to the Charcot foot. Problems with beam failure and migration have resulted in unsatisfactory outcomes as will be discussed. New Charcot-specific beams are currently reaching the podiatric surgeon with hopes of improving durability. In this article, we aim to address the surgical art of the beam, the engineering principles of beaming, and the novel introduction of a truss/tie rod configuration of beaming.
