3d measurements of bone architecture in weight-bearing to enhance plantar loading analyses in the diabetic foot

Pathomechanics of diabetic foot ulceration has been largely investigated by plantar loading measurements, and recently also by human motion analyses [1]. Rarely medical imaging has been used, because this is static, and also radiograms are in 2D, and standard CT scans are performed in supine, i.e. in non-weight-bearing conditions. Modern CT devices now allow 3D geometrical measurements on the foot under load, finally giving access to the full bone architecture in weight bearing. The present preliminary study investigates correlations between dynamic plantar loading and 3D bone alignments.
