Safe zones

Safe zone in the lower half of the tibia shaft

For the insertion of tibial Schanz screws in the lower half of the shaft, there is a wide safe zone from the sagittal plane, medially to the coronal plane. These screws will normally be inserted sagittally.

Take care not to penetrate the posterior cortex excessively as this will impale the tibialis posterior muscle and even endanger the posterior neurovascular bundle.
