From what I can see, its a graft onto the hip bone which adds significant width. They say its completely safe, of course take this with a pinch of salt! As Maid Marion rightly says theres a issue with if the body will tolerate the metal, and of course, other complications we have not yet foreseen......Hips is a difficult area to operate on....would not be like leg bone lengthening, which is a dangerous enough thing, but not as dangerous as the idea of trying to do that bone lengthening to the hips (I struggle to see how it could be done to the hips?)
As they also say lipo, bbl, and butt implants don't do much for shape (trust me, they do!.....case in point is look at Nikki Minaj circa 2008, and today. She looks amazing, of course some of this will be surgery)
Hopefully this will prove safe, and will add to the arsenal of surgical options for the aspiring Bombshell xx
