Thank you for responding so quickly.
In fact if I put in a fixed position, standing and a x ray was made, a pelvic shift would be clearly visible. But in addition to this shift, with manipulation, for example if an osteopath and the fact that the pelvis is moving, it will see and feel a large left pelvic anteversion with his hand.

To answer your first question, my problem is not caused a car accident or a fall or a malformation, it is a "wrong move", I can't describe to you what I did it as manipulation because it does not have a name in technical terms so I would say it was a "wrong move", a left pelvic anteversion to be more accurate than I did with my hands. I manipulated my left pelvis. If you want to know why I did that I could you explain in detail later, but now it does not really matter, today it is severely blocked.

For your second question, my pelvis is indeed blocked in one position, but if I try to do an hip extension, hip flexion, the left pelvis will tend to have excessive anteversion coupled with internal rotation.

For the third question, 10 cm, it is a way of speaking to say that it's huge shift. It is an estimate made by eyeball.
"Turning Inward" was to say that the left pelvis perform an internal rotation and "it never cam up" to say that I could never put it back in its normal position.
The direction of alignment is in a plane transverse and slightly more frontal (anteversion, internal rotation).
The reference point is the left iliac bone, spine and navel.

For your fourth question, this problem prevents me from playing sports, running, to feel good about myself, I am often stressed, I feel stuck, it has already wasted six years of my life and if I can find no solution that will continue.
This is mainly due to stiffness, a severe blockage. I have very little pain. If there is pain I think it's mainly due to compensation caused by the blockage.
Sorry for my English. I'm French and I don't speak English well. I use a translator.
