Ankle-Foot Orthosis Made by 3D Printing Technique and Automated Design Software

Figure 1

The line between the second metatarsal head (MH) and the midpoint (C_T) of the lateral (LM) and medial malleoli (MM) was assumed to be the axis of the foot, and the line between the midpoint (C_T) of the lateral (LM) and medial malleoli (MM) and the midpoint (C_K) of the lateral (LT) and medial tibial condyles (MT) was assumed to be the axis of the lower leg (a). The preprogrammed orthotic template design which size was modified according to the marked points was overlapped (red dots and lines), the circles were drawn around the lateral and medial malleoli, and the oblique line was drawn (blue dots and lines (b)).
