[Design and application of adjustable triangle external fixator for the treatment of calcaneal fractures].

Objective: To design a kind of adjustable triangle external fixator, and to use it for treating calcaneal fractures.

Methods: The external fixator was installed into extremity near the both sides of three Kirschner wires crossing the calcaneal tubercle, the lower end of the tibia and the first cuneiform. The support rod length was adjusted to ensure the Kirschner wires affecting the calcaneal tubercle, so the Böhler angle and anteroposterior diameter of the calcaneus were recovered.
