With the “Ankle & Foot” module, doctors have the opportunity to sharpen their eye for the different conditions. On the basis of twelve cases, Professor Iris Eshed from Israel introduces the systematics of these diseases and shows how they can be differentiated from one another. In the course of this, osteoarthritis and other forms of arthritis are compared, whereby rheumatic disease in particular is often difficult to recognize in practice. Tumors are added to the range of differential diagnoses.
