“To my mind, is an unproven modality and based upon current evidence would have to say it works as well as vertebroplasty, which is to say likely to work as well as a placebo,” says Rachelle Buchbinder, a professor of epidemiology and preventive medicine at Australia’s Monash University, as well as a co-author of a recent vertebroplasty review published by the Cochrane Collaboration, a network of independent researchers. Some are concerned about the money being spent on a procedure that’s controversial and sometimes risky. (It’s hard to say an exact number, as the procedures are not recorded in any national database.) In 2011, Medicare paid out around $1 billion for vertebroplasties and kyphoplasties, and the number of the procedures performed each year is not estimated to have decreased significantly since then. By the time two studies published in 2009 found that vertebroplasty-and, by extension, kyphoplasty, which is similar but has not been tested in controlled experiments-was no more effective than a placebo treatment, at least 100,000 of the two procedures were being performed every year. The procedure grew popular in the ‘90s, despite the fact that its effectiveness wasn’t backed up by definitively convincing research. The procedure is meant to reduce the pain of a fracture, even though it sounds unpleasant: It consists of inflating a tiny plastic balloon near the fracture, removing the balloon, and then injecting a toothpaste-like plastic cement into the resulting crevice and letting it harden. Kyphoplasty, along with vertebroplasty, the procedure it shares a Wikipedia page with, is a common treatment when someone’s spine breaks-a frequent occurrence in people with osteoporosis, which makes bones brittle-and then doesn’t heal naturally.

The page originally suggested that the procedure’s effectiveness was “controversial,” and an unidentified Wikipedia user had proposed changing the text to “well documented and studied”-a characterization that Heilman thought wasn’t supported by existing research. Support Ukrainska Pravda or become our patron.On January 11, 2013, James Heilman, an emergency-room physician and one of Wikipedia’s most prolific medical editors, was standing watch over the online encyclopedia’s entry for a back procedure called a kyphoplasty. Journalists fight on their own frontline.

Oleksii Danilov, Secretary of the National Security and Defence Council of Ukraine, has said that the murder of Darya Dugina, daughter of the Kremlin ideologue Aleksandr Dugin, was executed by Russian secret services and that Ukraine has nothing to do with it.

Russian President Vladimir Putin awarded Darya Dugina the Order For Courage posthumously.

Ponomarev later stated that Russian propagandist Darya Dugina would not have been assassinated if the bombers had known that her father was not in the car.

Ilya Ponomarev, a former member of the State Duma of the Russian Federation, said that the so-called National Republican Army (NRA) has claimed responsibility for the murder of Darya Dugina, the daughter of "Putin’s ideologue" Aleksandr Dugin.

Russian propagandists began calling for new strikes on Ukraine after Dugina's death, and her father said he was seeking not only revenge, but "victory".

The FSB of the Russian Federation claimed that Ukrainian Natalia Vovk, who allegedly served in the Azov battalion, was responsible for the explosion – the soldiers of the regiment denied this.

Russian investigators believe that the car in which Darya Dugina was killed in an explosion was blown up remotely.

The Office of the President of Ukraine denied any involvement of Kyiv in Dugina’s assassination.

Dugina was the daughter of "Putin’s Rasputin" Aleksandr Dugin and she wrote about politics for Tsargrad and RT, two Russian Kremlin-aligned media outlets. On 20 August, a car driven by Darya Dugina exploded in flames not far from Moscow.
