Optional medical device diagnostics – depending on the results of the history, physical examination, and obligatory laboratory parameters – for differential diagnostic clarification.
- X-ray of the foot (dorsoplantar and the lateral X-ray = standard planes of foot X-ray diagnostics) [luxations of the MTP joints (metatarsophalangeal joints; connect the metatarsal bones with the toe bones); flexion positions of the toes; measurement of the hallux valgus angle].
- X-ray of the affected region, in two planes – if symptoms persist and to exclude Köhler’s disease II (aseptic bone necrosis in the head of the ossa metatarsalia II-IV (metatarsus); more common in young girls).
- Sonography (ultrasound examination) of the affected region [bursitis (bursitis), ganglions, joint effusions, interdigital (“between the toes”) neuromas (“nerve nodules”), and pathologies of the tendons]
- Pedobarography (digital imaging of the pressure load on the foot during stance) – Indications:
- Objectification of the pressure conditions of the foot.
- Progress control after therapy has taken place or after corrective surgery.
- Computed tomography (CT) – sectional imaging method (X-ray images from different directions with computer-based evaluation), particularly well suited for the representation of bony injuries (post-traumatic situations) and deformities; in the presence of implants.
- Magnetic resonance imaging (MRI; computer-assisted cross-sectional imaging (by means of magnetic fields, that is, without X-rays)) or 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) – to exclude a stress fracture; by means of MRI, the soft tissues such as the bursa (bursa) can also be evaluated
