Clin Podiatr Med Surg. 2018 Oct;35(4):423-442. doi: 10.1016/j.cpm.2018.05.003. Epub 2018 Aug 11.


To provide standardized nomenclature for various hexapod frame configurations for foot and ankle deformity correction, a unique classification of the hexapod external fixators was proposed. This classification is based on number of correction levels, secured anatomic blocks, and direction of the strut attachment. It allows the combination of all different foot and ankle frame assemblies into a few standard hexapod configurations, irrespective of which external fixator is used.

Keywords: Circular external fixation; Classification; Deformity correction; Foot and ankle; Hexapod assemblies; Hexapod frame configurations; Ring fixation.
