Optional medical device diagnostics – depending on the results of the history, physical examination, laboratory diagnostics, and obligatory medical device diagnostics – for differential diagnostic clarification.
- Radiographs of the affected region – to demonstrate arthritis (joint inflammation), osteomyelitis (bone marrow inflammation), march fracture, etc.
- Skeletal scintigraphy (nuclear medicine procedure that can represent functional changes in the skeletal system, in which regionally (locally) pathologically (pathologically) increased or decreased bone remodeling processes are present) – in unclear X-ray findings.
- Angiography (representation of blood vessels by contrast medium in an X-ray examination) – in case of suspected ischemic foot (reduced blood flow to the foot) with rest pain.
- Magnetic resonance imaging(MRI; computer-assisted cross-sectional imaging method (using magnetic fields, that is, without X-rays); particularly well suited for imaging soft tissue injuries) of the foot (MRI foot).
