In the frontal plane osteotomy, the first plate is applied to the dorsal aspect of the bone. The plate is attached to the proximal fragment first. If a DCS plate is used, the barrel is placed in the proximal metaphysis.
The long axis of the plate is used to guide axial alignment of the osteotomy fragments. Once the proximal plate is attached, the screws are placed in the distal osteotomy fragment using the dynamic compression principle to create axial compression.
