Increase Load-Sharing to Stimulate Callus Formation
When the external fixation frame is used definitively, the surgeon may wish to increase load-sharing. Once the soft tissues are healed and the patient has progressed to full weight-bearing, the frame may easily be adjusted to transfer load to the fracture site to stimulate callus formation (3).

Reduce Frame Rigidity

• Remove the secondary frame (e.g., a two-plane unilateral frame becomes a one-plane unilateral frame).
• Remove the second rod on a double-stacked unilateral frame.
• Increase the distance between the rod and bone.
• Decrease the number of Schanz screws in each fragment.

Note: Always maintain at least two Schanz screws in each fragment.
