Hi Niki, my computer does not support Russian, so I will write in English.
Go to the www.jcharleystaylor.com-table of contexts.-Abstract TSF as virtial hinge.I will citate it for you:TSF has been mechanically tested for stiffness.Compared to Ilizarov frame TSF is:
1.1 times as stiff in axial compression;
2.0 in bending
2.3 as stiff on torsion.
You know exactly who is Charlie Taylor, if he said that he is tested, I belive he did what he wrote.
Another source for information is J.Binski paper
( you can find reference in my paper above).I'm sending also PDF file of TSF hardware.
 TSF presentation hardware manual Doni site.pdf, 1092KB (1118665 bytes)
Sasha Chelnokov- most not TSF surgeons tested stability of TSF frame above the table on saw bone models( usually on the congress demonstrations, when all struts even mot tightened firmly enough!).
Today I did many frames, believe me my patients did not suffer from frame instability, if you remember I discussed in Kyoto ways how to dynamize TSF.
I think that hexapod in Russia will work , you have huge amount of the Ilizarov equipment.But I dont use TSF for correction of simple fractures and ordinary lengthening, Ilizarov will do the same job.My feeling that TSF and Hexapod usung same mechanism, but Mersedes and Lada similar also( both are cars!).Today I'm doing many foot cases, show me another frame were you can correct varus, supination, aquinus, rotation and cavus by simple mouth clicking!!!This is true hexapod using same idea as TSF, both working on the same principe of the Stuart platform, the difference is that behind TSF are standing Smith and Nephew and after Hexapod few germans surgeons.
Finally thank to Yakov, good presentation of ineteresting idea.
Mark Eidelman.
