name. With the octopod method the device can reach a wider correction range, thereby solving a major problem of the 2nd Generation Circular External Fixators, that of having to frequently change struts. The previous difficulties in taking manual measurements when using both 1st and the 2nd Generation External Fixators are resolved by using the 3rd Generation Circular External Fixator. Dr.

Gavril A. Ilizarov Gavriil Abramovich Ilizarov (russian: Гавриил Абрамович Илизаров; 15 June 1921 – 24 July 1992) was a Soviet physician, known for inventing the Ilizarov apparatus for lengthening limb bones and for the method of surgery n ...

in the 1950s. His technique served as the foundation for his invention, the 1st Generation Circular External Fixator. His method and the apparatus he invented are the oldest and most common method of distraction osteogenesis. The first 2nd Generation Circular External Fixator, an Hexapod External Fixator Frame, was developed in the 1990s. Even though the 2nd Generation External Fixator represented an improvement over the 1st Generation, it was very cumbersome to use manually.

method are many times inaccurate, leading to complications when controlling the bone deformity correction. In addition, the dependence of the patient on the hospital is increased in cases of severe deformities, which require strut exchange when using the hexapod method. Since the treatment cannot be finished in one session and requires frequent check-up, the patient suffers additionally from more

If desired, surgeons can also use the fixator without the software, as with the previous generations of fixators. Adam Frame provides a complete product and system which integrates all the advantages of the previous models into a new design.
