Check this video out!!
Her walking is pretty ace while lengthening. She had stryde I think.
But check out the x ray at 1:10 and 0:57. Thats like a huge nail shoved into the bone. Is it okay?
wow, first of all thank you for uploading the video!
& yeah i was wondering the same about the nail its like the whole bone is reamed how the f is that possible.
yo can anyone know what size nail is that ?
I have no idea...
The way you can differentiate different nail sizes is by looking at the locking screws.
All stryde nails have 5mm pegs at the female part (the large part of the nail)
the 10mm nail can be recognized because the female part is wider at the top( 10.7mm) so this is not a 10mm.
the 11.5mm nail has 4.5mm pegs in the male portion (they look smaller than the top screws)
the 13mm nail has 5mm screws in both locations and thus look the same.
This is how, ladies and gentlemen, you differentiate the nails just by looking at an X-ray
. This seems like an 11.5mm if I measure the proportion between top screws and nail. However those xrays are too blurry to tell for sure.

I think what stuck out to them was that the nail spanned most of the bone. I remember Dr. Paley once mentioned how for cosmetic patients he uses short nails. Are there different length implants as well?
We try to use the Shortest Nail Length (SNL as coined by Dr. Rozbruch) necessary to obtain the desired stroke.
SNL = distance to osteotomy site + 8CM buffer zone (to prevent implant breakage) + desired lengthening

Is it a good idea to fit such a large nail inside the bones of a petite woman? In the above x-rays there is hardly any bone left to the sides of the nails. Is that ok? What could be a valid reason to not use stryde 10mm?
We try to use the smallest nail diameter possible that will provide a good fit and stability. The disadvantage of using a 10mm nail is that its weight bearing capacity is limited to 150lbs, compared to 200lbs for the 11.5.
In addition, smaller diameter nails tend to bend more when fully lengthened with an 8cm bone regenerate. By bending, they induce a varus deformity and may even break (remember, their weight bearing capacity is with axial load on an intact nail, not a bent nail)
