After tapping, insert the DCS over the guide wire, so that its outer end is
still visible 2-3 mm outside the lateral cortex of the distal femur.
In order for the plate barrel to slide over the screw, the T-handle should
be parallel, on the lateral view, to the long axis of the distal fragment.
Pearl: omit tapping in osteoporotic bone
In osteoporotic bone, tapping should be omitted.
