yeah I didn't read a diary about lengthening one leg, but this happening all the time with ppl who have leg discrepancy ..
sure she'll take longer time, but she wont lose her mobility ,, and I think this the hardest part in LL not the pain part..
the girl look hesitated form beginning if she'll do her femur/tibia in one leg first she'll have clue for what's waiting for her in LL journey.. and she can do her second leg once she's comfortable with that .. this is just my opinion . and I think I read once that Dr Paley (not sure that was from long time) used to do one leg lengthening (both tibia and femur)
about femur lengthening. yes I found it less painful ,the pain in tibia during the distraction was 7/10 maybe but the femur something like 4 , but the frame were pain in the ass, so uncomfortable , also you'll lose your knee rom which is much worst .. even though you may gain your knee rom with pt, but I still don't think it's worth it, I'll go with the internal femur lengthening from the beginning and I'll avoid all this drama ..
with which doctor you consider lengthening femur if I may ask?
