Soviet Fixator Heals Fractures Just as Well as Pins and Screws

14.10.2014

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.

Scientific evaluation
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.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
