[Pathomechanism of calcium phosphate arthropathy based on a case]

Authors describe the case of a 43 years old male patient with complaints and restriction of motions since years, localized on the talocrural joint. In the background of the disease, responding inadequately to the therapy, calcium pyrophosphate depositions were found in the joint tissues. As the pathomechanism of the disease is even presently not cleared authors summarize our present knowledge referring to this problem.
