Figures & data
Figure 1. (a) Iliac crest line. (b) Intergluteal cleft. (c) Gluteal sulcus.
Figure 2. Skin fixed DRF on the midline instead of bone fixed DRF on one side of PSIS or spinous process. Skin fixed DRF could be placed as close as possible to the surgical field without hindering the navigation during screw placement.
Figure 3. Lateral picture of the skin fixed DRF on the area between iliac crest line and integluteal cleft.
