In our work we used glass pedograph with digital camera under pedograph, computer and ultrasonograph. For tibial torsion measurement a patient was standing on the glass pedograph. A luminodiods was settled directly under tips of malleoli. Ankle joint axis passes through tips of malleoli and it was distal reference line. Rectangular ultrasound scanner probe was placed in parallel with posterior margin of the proximal articular surface of the tibia, it was proximal reference line. To avoid optic distortion we placed crus axis in line with optical system axis. Photoplantogramm was captured and estimated. We estimated angle between two reference lines (direct method of tibial torsion measurement). We measured tibial torsion with our method and MRI (5 patients, 10 legs). Tibial torsion measurement by MRI was performed by Schneider method (1997). Mean value of tibial torsion was 290 (our method) and 400 (Schneider method). Pearson correlation coefficient was 0.9. Dynamic photoplantography is cheap, informative, easy method in early pathology revelation. It can be used as screening method among large collectives. Functional photoplantograms help us to estimate foot arch function. Treatment control is very easy to perform with dynamic photoplantography
