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.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
