Time in frames for 6-7cm of external lengthening?

Edit Post

I've been considering 6-7 cm of tibial lengthening with Dr. Leonid Solomin in late 2022/early 2023, and I was previously of doing LON, but I've since learned about the possibility of chronic knee pain doing that. So, I'm now thinking about pure externals. The question is, of course, how long do you have to stay in frames with pure externals? I've heard the rule of thumb that 1 cm of lengthening is equal to 1-1.5 months in the frames, but I want to know how accurate that is from people's experiences. Thank you.

1 month per cm is more common for children. Realistically it's more like 1.5 - 2 months in frames per cm.

Yeah, there’s just no way I’m going to sit in frames for 1+ years. I’d rather just do LON or internals if necessary.

For more than 5 cm better take risk of knee pain.

With external frames (Ilizarov's or adapted franes)  in tibias there is generally an average (it may have to be adapted to each one situation, response, exerience if surgeon, physiotherapy, etc.) of: 1 day for each mm lenghtening and the double for its consolidation, so to sum up, 3 days in frames per 1 mm, or 6 months (180 days) for 60 mm (6 cm). This is just a generally indicative timetable.

Chronic knee pain in nail systems in tibias is largely not yet fully understood and not only due to manipulation of patellar tendon but of multifactorial origin. It may be atenuated with time and physiotherapy...or not. It has no proper, directed, therapy.
Why do you say it's a good idea to risk forever pain just to save 2 or 3 months with frames? Sorry, but in my modest personal opinion it seems not to make any sense! Would you do that?

But beware that all nails (not only LON) for tibias are inserted in the knee region (except some "creative" doctors) touching or manipulating the pattellar tendon, generate huge blood loss) more risk of clots, etc) and don't provide means of correction (for rotations, deviations, etc), reversion for consolidation improvment, etc. Internals are more suitable for the anatomy, practice of surgeons, etc, for femurs.Besides tibias are more curved, fragile bones.

I am in a similar boat as you. For tibias I chose ideally Ilizarov done preferably by one among the more reputable clinical and LL surgeons. But altough, ideally, money shouldn't guide the decison, my 3rd choice may be LON after a bit more of further investigation.

Time in frames for 6 cm is almost 1 year, uisng LON not more than 2.5 months so is not 2 months is more than 6 months more with pure external

Dr. Mitkovic told me nine months for 7.5 cm.

I think that can be possible but in the worst case it would take more than a year.
