Is 7 cm bad idea for tibia?
« on: April 17, 2024, 07:00:28 PM »

Hi everyone. My height is 176 cm and I am going to do only one surgery and I want to lengthen 7 cm for tibias, would it be a disproportional?

Depends on your current proportions. If your tibia is relatively short compared to your femur and upper body, then it can be done, albeit with much effort and risks. Also, consider being in frames for about 11-14 months for that amount of lengthening if not considering LON or LATN.

I myself have short tibia and short starting height to begin with. That's why I'm shooting about 7 cm and am mentally ready to remain in frames for that long time as doing LON or LATN is more invasive and costly.

I am going to do it using LON and yes + 7 cm for my body and legs looks normal even more then 7 cm looks mormal but 7 cm is max safe limit

Max safe limit is more like between 5-6 cm but if you push harder 7 cm can be done.

LON is more invasive and has risks of permanent knee pain but I understand that being in frames for almost 14 months is mentally exhausting so if you have funds then go for it.

But you have a pretty good starting height and 4-5 cm pure external would suffice which can be done in 6-8 months without LON or LATN. Much safe than 7 cm and doing LON.

Can do it, but recommended is 5-6. But afaicr Bodybuilder pushed 3 inches and is quite fine, so yes it's still possible but usually will depend. IMO proportions would still be your limiting factor, if you have short tibias and lengthen at that and be within the range of proportion for tibia:femur, then go ahead if you can. I personally have long tibias, short femurs(still longer than tibias) and a long torso, so my calves look quite big, so I plan to do this surgery on my femurs.

Hard limit will be as long as your tibia is still shorter than your femurs, if you go past that, it'll just look very weird esp considering it's very rare to have longer tibias than femurs. In fact, it's actually not recommended to have longer tibias than femurs: https://pubmed.ncbi.nlm.nih.gov/26398436/#:~:text=Discussion%3A%20Increasing%20tibia%20length%20relative,the%20normal%20ratio%20of%200.80.

No matter how much you want to grow taller, minimize the risk of your mobility and plausible joint problems.

Ideal goal: (178cm~180cm) 5'10~5'11 with two separate bilateral(femur+tibia) lengthening
Normal goal: (176cm) 5'9 with femur lengthening
Minimum goal: (173.5cm) 5'8 with femur/tibia lengthening

Plan in 2025~2026 when Precice Max comes and has some good outcomes.

If we are talking strictly about proportions, long tibias are aesthetic. In my personal opinion, extra long tibias look better than extra long femurs. That's just my personal belief, some may disagree.

As far as safety goes, lengthening the tibia 7cm is much harder than lengthening the femur 7cm. It is dependent on the individual, but it may not be possible in your case. Most would probably have to stop due to contracture or developing equinus before they reach 7cm.

Current LL plan:
QLL in Early 2025 using the PRECICE nail with Dr. Birkholtz.
4cm tibia, 4cm femur. One year later, re-break for another 4+4. 167cm -> 175cm -> 183cm

Aesthetically you will look fine with 7cm on tibias. Also yes it is a feasible length and if you lengthen slowly and stand a lot (to avoid equinus) you'll probably be ok.
But your biomechanics will be ruined so if you want to run, play sports and all these then with 7cm you won't be able to do it, simple as that.
You will walk fine, you would do all normal things but nothing more than that in a level close to before LL.
Personally I don't care at all because at my initial height, gaining 7,5cm and reaching a solid 1.76 (morning height) was much more important than having much better athletic abilities and be 1.74. I only lifted after all, which I still do in a very good level (better than at least 95% of men even younger than me) so I never cared about running for distamces, olayng football and things like that.

That said, at your height I wouldn't push it that much because even with 5.5 cm I would have had an almost perfect height and much better athletic abilities compared to 7cm. So it doesn't worth it imo at your initial height. Go to 5.5cm and consider yourself done. 1.81 with 1.83 has no real difference but not able to run fast or for distances has.

When I look in the mirror nked, especially laterally, my shins are much shorter compared to thighs. I think that anything up to 5 cm won't create obvious disproportion between them but anything past 5 cm will start to further damage the ratio between lower and upper legs. Every 0.5 cm above 5 cm is not only hard to lengthen but also creates visible disproportions gradually. But in my case I think that up until 6.5-7.5 cm will be more or less acceptable given my short lower legs.

I have to measure my bones first and not exceed the length of femurs or else I'll look odd then. When I'm measuring my tibia from distal and proximal heads of the bone, I get about 35 cm. I think that femurs should be at least 7 cm more so about 42-43 cm, but measuring femur bone accurately without getting x-rays is erroneous so it might be 40-41 cm, who knows. I think that there's no way I lengthen femurs first as my tibiae will look even shorter that it is now and I'll look odd nked but okay with elevator boots and longer pants but I want to look good nked in the first place so tibia is my first choice up to 7.5 cm and then femur up to 5-6 cm max.

I don't do heavy squats and deadlifts. Never did heavy even before LL but furthermore after it and after 30yo. I don't want to ruin my body with injuries.

With isolate exercises I have a very good body and muscle mass. I am not a powerlifter nor I care about lifting heavy, I just want a good looking muscular body and I am ok with how I look.

I am able to sprint  but in 30-40% slower than before and much lower distances.

The safe limit for the tibia is 5 cm. If you want to increase your height by 7 cm, you can lengthen your tibia by 3.2 cm and femur by 4 cm. Or 2.8 cm tibia and 4.4 cm femur. You will lose 0.2 cm at the Q angle.

Tibias LL is more painful and complicated than Femur.
IF you want 7cm, why dont you do Femur?
Tibias 5-6cm is safe and common.
Do check your Tibias to Femur ratio. This ratio is critical to avoid long term chronic pain.
You can google and check.
Proportion should be ok as long as your hands are not too short.

IMO in the end everyone should lengthen the other segment too in order to regain natural biomechanics which is 0.8 tibia to femur ratio.

That's why it's better to not lengthen tibia more than 5.5 cm as you then have to lengthen 7 cm on your femurs to regain 0.8 tibia to femur ratio.

5.5 cm on tibia is already stretching it and can be done without permanent achilles tendon problems if one is really flexible and young enough.

Now, 5.5 cm tibia means that you have to lengthen exactly 7 cm on your femurs (no more and no less) which is considered the same in safety profile as 5.5 cm tibia lengthening.

So, basically, with double LL it's only safe to lengthen up to 5 inches exactly (more likely 12.3 cm if we subtract the Q angle from femur).

12.3 cm net height increase is a huge jump from any starting height IMO and is only worth it if one is really short like between 5'5-5'7. If someone is 5'9 for example, he must either do 5 cm tibia and be done with it or if he cares about perfect leg proportions and have enough money, time and energy should do 3.5 cm tibia and 4.5 cm femur for 3 inches total max as there's no point in risking more than that if one is hovering between 5'8-5'9.

IMO nobody should undergo this grueling procedure more than once if someone can get away with increasing tibia length up to 5 cm to stand at 5'10-5'11 and at 5'10 and above nobody should think about LL unless it's for deformity or obvious disproportion correction between limb segments (so, height gain should be a secondary goal in this case).

For anyone below 5'8 like guys 5'5-5'7 have no choice other than doing both segments as if one does 8 cm femurs he will look deformed until he does at least 4.5-5 cm tibia too.

So, unfortunately, no single LL for guys who need more than 5 cm as doing femur for just 5 cm is pointless as it's much expensive and doing tibia for more than 5 cm is asking for trouble and a matter of luck.

Anyway, if one lengthens more than 5.5 cm on tibia he will look disproportional nked until he lengthens femurs too for at least the same amount (ideally 1.25x amount of tibia) to regain proportions and biomechanics.

So, the best route of someone who needs double LL to become average height is to do tibia first and never go above 5.5 cm and then do the femurs for exactly 7 cm to regain perfect proportions between the limbs.

I think that the best aesthetic result I've ever seen on a 5'5 guy who did both segments is jim_dabarber who did 4 cm on tibia and 5 cm on femur for 3.5 inches of total height gain. The final photo he posted in his diary when he regained the muscles on his leg was very aesthetic and natural.

Unlike other dudes who post post lengthening photos with clothes he posted the pick nked with only underwear to show off his whole body proportons after the lengthening and rehab.

This is how he looks like and I think that 4 cm on tibia and 5 cm on femur is the ideal goal in terms of safety and proportions.

But, if someone has really short legs and big upper body and wants to gain the maximum safe height from double LL than 12.5 cm is the upper limit where if someone's starting arm length and shoulders width is fine enough to look acceptable post lengthening. Anything more than 2.3 inches on tibia and 3 inches on femur will look bad on any starting height (especially the lower the starting height is).

So, basically, 5'5 guys can become 5'10 maximum and look acceptable only if they have really short legs compared to upper body and at least the same wingspan as his original height + has decently broad shoulder and frame.

IMO jim_dabarber could pull of 5.5 cm tibia and 7 cm femurs and still look acceptable.
