Grigorenko Update I haven't been able to confirm this yet but I'm hearing now that Igor doesn't just have a broken hip as his main problem. He's apparently in critical condition, comatose and on a vent. He has been diagnosed with a fat embolism which is similar to a blood clot but more serious because it cannot be treated with anticoagulants (which dissolve a blood clot). This is much more serious than a hip fracture.
