>>13813093Sanders and Frykberg Classification system is used for addressing Charcot's Diabetic Foot.
>Type IMetatarsophalangeal Joints (toes), affected 30% of the time
>Type IILisfranc joints, THE MOST COMMONLY AFFECTED bone in Charcot. This is what causes "cube foot". 45% incidence rate
>Type IIITalonavicular, Calcaneocuboid joints (midfoot). Like 30-40% of the time
*NOTE: %'s add up to >100% because frequently multiple types are found in one case*
>Type IVAnkle joint. If this breaks down then it leads to instability. 3-10% of the time
>Type V Calcaneus (your heel bone). Your heel breaks like 5% of the time, and it's often an avulsion of the posterior portion of the calcaneus. An avulsion is when a tendon flexes so hard it pulls off a chunk of your bone. Avulsions are typically indicative of insufficiency fractures, i.e., osteopenia.
