Safe corridors in external fixation: the lower leg (tibia, fibula, hindfoot and forefoot).

It is a prerequisite for surgeons using external fixation systems to be familiar with safe corridors for half pin or wire insertion. Several atlases of cross-sectional anatomy are available, mostly in print, to provide guidance [1-3]. This series of articles provides high-quality cross-sectional anatomical images together with guidance in locating safe corridors; the added benefit here is that the information can be downloaded and stored on the surgeon's or in the operating room computer for ease of reference. This review covers the lower leg from knee joint to foot.
