he explained that requires breaking the leg in four pieces and resetting it so that the femur is no longer twisted
I do so hate it when people say "breaking the leg" as it sounds as if it's a random thing like we just take a hammer to it! The correct terminology is osteotomy which involves very carefully planned and executed cuts with a power saw.
The procedure he is describing is a called a Ganz rotational osteotomy and is a very old procedure - been around for decades! The operation involves making controlled cuts in the three bones that make up the pelvis: the Ilium, the Ischium and the Pubis - like so.
Once these cuts are made, the socket is moved into the optimum position and screws are used to hold it there until it heals.
Some things I must tell you about this procedure which I suspect that the surgeon may not have mentioned:
1) it is a
very major procedure
2) it can take 3-4 hours
4) initial recovery requires ICU admission
5) recovery afterwards is painful and protracted and may take many months
However, having said all that, they are generally fairly successful in the long term and don't have any restrictions though she will be somewhat handicapped for some months while it's all healing.
On the other hand, a hip replacement will be quite different. I expect you've read Jasmine's thread
teenager hip replacement after SUFE so you can see how much more quickly things progress. The surgery takes about 1-1½hrs, the initial recovery is swift with a discharge after only a day or two. Thereafter the recovery is also fairly swift as she will be up and about within 2-3 weeks at most and back to school about 3 months after that. Her hip replacement will very likely last her about 30-40 years despite the negative predictions of some!
This whole episode took nine months in total to recover (and probably caused SUFE).
That's unlikely but anyway, actually irrelevant now. That was a long old recovery.
If you look on Jasmine's thread, you will see there the name of the surgeon I recommended and who did indeed to Jas's hip replacement. It will be well worth the trip.
