Modular external fixator

The modular external fixator is optimal for temporary use. It is rapidly applied without need for intraoperative x-rays and can be adjusted later.

The frame of a modular external fixator consists of two partial frames (a, b), one on each main fracture fragment. Each partial frame starts with two pins in a bone fragment, connected with a rod. The two frames are joined with a rod-to-rod construction/connecting rod (c).

This allows manipulation and reduction of the fracture after pin placement and guarantees sufficient stiffness of the frame. It also allows pins to be inserted through safe zones, avoiding traumatized soft tissues.
