The pins in the tibia should start approximately 1 cm medial to the tibial crest, on the anteromedial aspect of the tibia.

Safe zone in the midshaft of the tibia

The neurovascular bundle with the anterior tibial artery and vein, together with the deep peroneal nerve, runs close to the posterolateral border of the tibia.

These structures are at risk if the pin is inserted in the direction indicated by the red dotted line.

The pins in the tibia should start approximately 1 cm medial to the tibial crest, on the anteromedial aspect of the tibia, and are angled approximately 20° from the sagittal plane.
