Nice, not only finally getting some concrete news about Precise Max but straight from Dr. Paley with you interviewing. I submitted my 2 questions, looking forward to it. In case something goes wrong with the email, here they are again just to be sure:
"A common topic of discussion when it comes to LL is the tibia to femur ratio, which for most men tends to be 0.80 with relatively little deviation. Some people claim that deviation from this ratio due to lengthening only one segment can cause various problems, including not just uncanny aesthetics and leg appearance but also altered biomechanics and other physical problems in the future (e.g. arthritis). However, it is also claimed that quadrilateral LL is more dangerous than single-segment LL.
Therefore, assuming time and money are not an issue, is it safer to do quadrilateral LL with per-segment increases such that the tibia to femur ratio is preserved, or are the risks of quadrilateral lengthening to end up with a normal tibia to femur ratio greater than the risks of doing single LL and ending up with an altered tibia to femur ratio? If it matters, I'm thinking of doing 7 cm: either femurs-only, or double, e.g. 5 cm for the femurs and 2 cm for the tibias (or whatever combination would preserve my tibia to femur ratio as decided by the doctor). Thank you."
"Relating to my previous question of single-segment versus quadrilateral lengthening: it is widely claimed that the risk of LL is determined by the per-segment increase, with each segment having its own safety limit. The general numbers often mentioned are 8 cm for the femurs and 5 cm for the tibias. Does that then mean that if a patient wants for example 7 cm of extra height, and time and money are not an issue, it's safer to divide that increase along the two segments, ending up with per-segment increases further below the safety limits compared to doing the whole increase on the femur, where it would be only 1 cm below? Or do the overall risks of quadrilateral lengthening nullify the decrease in risk from lengthening further below each segment's safety limits? Thank you."
