Background
There are obvious problems involved in the accurate description of movement of the intrinsic bones within the foot and ankle. The 26 small bones are difficult, if not impossible to individually represent with standard skin mounted markers for motion analysis [1, 2]. This international research collaboration has performed a number of studies in which invasively inserted intracortical pins are used for anchoring reflective markers, thereby providing a direct representation of the kinematics of the individual segments.
Materials and methods
Computer tomography images of the marker locations on intracortical pins in foot and ankle segments.
Results
Mean total ranges of motion (ROM) and standard deviations of motion about selected joints in the sagittal, frontal and transverse planes during walking. Data from six healthy, male subjects. From Lundgren et al., 2008.

Conclusions
A large range of fundamental data concerning foot and ankle kinematics during walking and running and with various manipulations have been collected and will be presented.
