Increase Load-Sharing, contd.
Dynamization Technique
Dynamize the Frame
Dynamization is the process of altering the frame so that the proximal (or larger) fragment can move axially while movement in all other planes remains restricted. This allows load transfer- ence to the fracture site while maintaining anatomic alignment. This functional loading appears to increase the strength of the callus and decrease the duration of immobilization after frame removal (4).

"Crosswise release," or the loosening of adjacent clamp nuts on a frame, permits dynamization. In order to perform crosswise release there must be two parallel rods, both in line with the bone axis and connected to the longer fragment.
