Structures at Risk During Percutaneous Screw Fixation for Talonavicular Fusion.

Background:: Talonavicular (TN) fusion using screws dorsomedially and dorsolaterally can cause neurovascular injury. The purpose of our cadaveric study was to evaluate the safety of percutaneous screw insertion in relation to dorsal neurovascular structures.

Methods:: Ten fresh-frozen cadaver legs were used for this study.
