Abstract
For this study a customized pedography sensor (Pliance, Novel, Munich, Germany) was inserted into the WBCT device (PedCAT, CurveBeam, Warrington, USA). The aim of this study was to analyze the correlation of bone position and force/pressure distribution. 3D bone position did not correlate with force and pressure distribution under the foot sole during simultaneous WBCT scan and pedography. Consequently, the bone positions measured with WBCT do not allow conclusions about the force and pressure distribution. Vice versa static pedography parameters do not allow conclusions about the 3D bone position.
Based on Richter M, Zech S, Hahn S, Naef I, Merschin D. Combination of PedCAT for 3D imaging in standing position with pedography shows no statistical correlation of bone position with force/pressure distribution. J Foot Ankle Surg. 2015;55(2): 240–246.
