That depends on the method you choose and LL goal.  if you dig around someone posted a chart with all the methods and their details including expected time.  I did Precice II Internal Femur and for that method plan on:

Surgery + one week before lengthening       7 days
1mm per day - lets assume max 8cm         80 days
consolidation period                                 45-60 days

I am interested in LL and have begun researching the process. The single most important factor, besides doctor, is the amount of total time it will take. This is highly important as it will determine when I have the surgery, if I have it.

Start date: day of surgery
End date: the first day I can walk around normally and experience a normal day (but does not include running, exercise, etc.)

About how long can I expect it to take from the start date to the end date?

Thanks!

Thanks afonso!

Follow-ups for you or anyone else who can comment:

1. Is the consolidation period directly proportional to the total lengthening or is it exponential, etc? I would plan on lengthening 6.35 cm, so would the consolidation period be proportionally less than 45-60 days or is the 45-60 days a fixed amount regardless of lengthening amount?

2. Is Precice II Internal Femur the fastest method? Is there a tradeoff between speed and safety?

If anyone has the link to that chart it would be appreciated. I shall try to find it myself.

This very strongly depends on which method you use. LON could have you walking normally within about 3-4 months of the surgery. The same is the case for the Salamehfix. Externals probably will take twice that time. Internals, such as the Guichet nail or Betzbone, might have you walking normally as soon as you are done lengthening! PRECICE won't have you walking normally for four months or so, but it's a pretty reliable nail, so I would recommend it more than externals or LON/LATN.

It all depends on what you do.

For me I'm hoping 2-3 months since Intend to do 4-4.5cms. Does anyone think it can be done that quick in that amount of length? But this is a great question that should be discussed.

you MIGHT be able to do 4 cm.

7 days to fly, and pack and get accommodation, do doctors checks, and settle in, and prepare the things you will need after surgery.

7 days for inflammation to go down before you can start lengthening.

then you have 2 choices.

1) potentially fk yourself up with massive balarina by doing 1mm per day for 40 days..... (ps you will not be able to do this amount even if you wanted to)

2) or option 2. do 0.66mm per day for 60 days.

option 1: 7+7+40= 55 days. it could be possible that you will in 1 months time be allowed to put LON on. but I doubt any doctor will take your external frames off as you will have not enough callus.

option 2: 7+7+60= 75 days 1 month later you can get LON placed on you. no doctor will let you remove external frame straight away.


remember. after you finish lengthening you have at least 1 month before lon can be placed and external frame removed. after this 1 month it will take 1 month before you can walk without your walker and with crutches.



conclusion.............. no way in hell can you achieve this in 3 months.


75 days + 30 days (when frame is removed)(and lon placed) = 105 days 3.33 months. and even at this point in time for 4cm. you WILL NOT BE ABLE TO WALK.

Right but could I be walking again in 2-3 to 4 months Max w/o support? I know if someone accidentally breaks their bone it takes 6-8weeks to heal so I'm hoping

4cms=40 days 6-8weeks= 3months total

Does this equation work?

I may be able to do it with Precice but not with LON. 4 months isn't out of the question but may have to do PT in America. It still shouldn't take more than 6 months.

internals slow bone consolidation tremendously. and the precise is not weight bearing.


you still might not be able to walk for an extended duration. just like lon.

to get back to walking properly you really need to give yourself 6 months.

you cant bargain with god. no matter how much you want something to be quicker the body has limitations. just take a 6 month break and deal with it.

For Precice I haven't seen any doctor differentiate consolidation duration with lengthening goal but my opinion the less the goal the shorter the consolidation.  That said I would still plan on a 60 day consolidation period.  I'm currently a LL patient in the consolidation period with a diary on this forum.  I'm at the 20 day mark follow my diary and at least you will have one example of how long it takes.

That's why Im considering 1.5 inches. Because walking is very important to me and the difference between 6'2.5"-6'3" is next to none. I'm aware it takes 6-8 weeks after lengthening is finished for your bone to consolidate adding 2 months to a 4month lengthening process.

For me, to lengthen 7.5cm, this took about 8-9 months.  Complications and setbacks are part of LL.  Plans of lengthening 1mm a day every day for 63 days straight to get 6.3 cm probably won't end up working out.

I agree with Medium.

How often in life has anything worked out exactly the way we planned? For me it rarely has.

If I want 6cm on femurs its probably 90 days to plan for hoping for no major setbacks. 8 cm on femurs 90-100 days .

I hope to be 6 inches taller and walking without aid 18-24 months after they first serve me up on a slab to be cut open. I think its a reasonable goal.

The best goal is to aim for 2cms per month which is .66 of a milometer. Should have little muscle tension there.

What I'm most concerned about is permanent knee pain. It seems to be very common with all internal methods. That's why I'm probably doing external tibias. Permanent knee pain is not something I want to have for the rest of my life.
