External Fixation Systems consist of various components used to build constructs to treat the indications listed below. External Fixation Systems are modular, therefore, different frame configurations are possible. An individualized configuration should be designed for each case to suit the specific application. All External Fixation System components are for single use only. Each External Fixation System is designed as a system and does not allow the substitution of components from other systems.External Fixation Systems are made from aluminium and stainless steel. It utilizes circular frame and half-pin fixation techniques and procedures for placement of the device. The device is intended to be centered on the axis of rotation. The device allows some adjustability to permit adjustment on the axis.
