The Ilizarov method is routinely used in eastern Europe in the treatment of bone fractures. Studies of Swedish patients have shown that the unorthodox steel frame has many advantages over traditional open surgery, opening the way for it to be introduced as an alternative treatment in routine Swedish healthcare.
The Ilizarov method was developed in the Soviet Union in the 1950s by Professor Gavril A. Ilizarov. The method involves drilling thin wires through the broken bone fragments, and subsequently affixing the wires to rings, which are held together by external struts. The bone fragments are in this way placed in the correct positions, and held in place during the healing process.

The method is routinely used in eastern Europe, but has only occasionally been used in the west, mainly for complex procedures such as leg lengthening. One exception is the Orthopedic Clinic at Skaraborg Hospital in Skövde, where more than 700 patients have been treated by the Ilizarov method since 2002.
It is namely the case that Telmo Ramos works in Skövde. He has long been interested in the Ilizarov method, and presents a scientific evaluation of it in a thesis submitted at the Sahlgrenska Academy. Dr. Ramos has investigated patients with lower leg fractures who have been treated using the Ilizarov method, and has compared the results with those from patients treated with traditional surgery, in which the bone fragments are fixed with the aid of pins, plates and screws.
As good as open surgery
The results show that the Ilizarov method gives results at least as good as an open surgical procedure. Further, the patients are not exposed to the risks involved in an open surgical procedure, they can be discharged more rapidly, and they can place load on the leg as soon as the fixator is in place, and during the complete healing period.
“When planning surgery for certain complicated lower leg fractures, it is often necessary to wait until the swelling has decreased before operating. This is not necessary with the Ilizarov method, and thus the patients do not need to stay in hospital as long. Further, the fact that the patients can immediately start to place load on the leg is beneficial both for rehabilitation and the quality of life,” says Telmo Ramos.
“The outer frame that is used appears at first sight to be clumsy and heavy. But our studies have shown that patients accept the treatment very well, and do not experience major difficulty moving around.”
Test on other fracture types
Telmo Ramos concludes that the Ilizarov method should be introduced into Swedish orthopedic care, as a supplement to the treatments that are already available. The scientists now want to continue and test the Ilizarov method for other types of fracture, including fractures of the wrist, heel bone, upper arm and pelvis.
The Ilizarov method may also be significant when developing new drugs designed to stimulate bone healing. This requires methods to fix fractures without leaving foreign material in the skeleton.
The thesis On the treatment of tibial fractures using the Ilizarov fixator was defended at a disputation at the Sahlgrenska Academy on 18 September.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
