A new method was devised for the evaluation of medial and lateral splaying of the foot on dorsoplantar radiographs made while the patient is bearing weight. This method involves use of a two-dimensional coordinate system; the axis of the shaft of the second metatarsal is the x axis, the intersection of the x axis with the proximal end of the second metatarsal is the point of origin, and the perpendicular to the x axis that passes through the point of origin is the y axis. This method was used… CONTINUE READING
