LON on Femur - 9cm goal height

Edit Post

8/25/23

It’s been over two weeks since my removal surgery and I’m back home now. I use a walker with wheels for 95% of my daily routine at this point and I feel like I’m slowly getting my strength and mobility back. My x-Ray results showed I did achieve over 9cm after being calibrated with a ruler next to the x-Ray, and the bone consolidation looks good considering it has only been two weeks. It is still difficult for me to stand fully upright, I believe I’m still losing about 1cm of height due to posture. That being said, with shoes on I am about 178cm which was exactly my goal. I am looking forward to continuously improving and getting back to my normal life.

Great diary. Looking forward to your updates.

On the last photo your wearing nike shoes which add like 1.4 inches to height and barefoot on the first photo. It might be more accurate to photo without shoes.

Thanks I appreciate it! Nike Air Force shoes add roughly 3cm and my are kinda worn out so I’d say they add only about 2.5cm. Barefoot I’m around 175cm right now but I think once my back straightens out I’ll be a solid 176cm

It is true that you have achieved a significant amount of lengthening, and I think that is great.
However, I have several concerns with this achievement:

(1) Was the ruler placed directly on top of the x-ray plate, instead of being placed on a platform at the same height as the distance from the x-ray plate to the femur?
If so, the ruler would not be magnified, while the bone would be, leading to inaccurate length measurements.

(2) A photograph taken after lengthening does not prove 9 cm lengthening for the following reasons:
　(a) Shoes are worn in the photo after lengthening. (noted by tallertaller)
　(b) The heel is not attached to the wall in the photo after lengthening.
　(c) The position of the top of the head cannot be determined due to the stamp that hides the face.

I occasionally see posts from patients who say they have shrunk since returning home, but in most of those cases the measurements at LL hospital are not accurate.

I’m not sure why you keep making so many comments saying I didn’t get 9cm. I know for a fact my nail was less than 11mm, it was a 10mm nail and by your own pixel calculations that would make my gap more than 9cm. Also the picture of me standing shows I went from 167cm to 178cm (with 3cm shoes that I stated in the forum). If you do the math 178 - 167 - 3 = 8cm and I said my posture is not very good right now because of lordosis hence the missing centimeter. I’ve also shown multiple x-rays displaying that I’ve lengthened 9cm. Moreover, I kept a comprehensive log of every time I lengthened on my external fixator so I know exactly how much height I gained. If it makes you feel better to think I got less height somehow you can go ahead and do that though.

The most significant reason is, while I'm unsure about your clinic, many clinics in Turkey do not perform accurate X-ray magnification correction.
As a result, patients often feel shorter after returning home than the height measured at the clinic.

Furthermore, if the thickness of your nail is 10mm, the pixel calculations don't align. There's a possibility the nail is actually thinner, and for precise assessment, the nail's exact diameter is necessary.

Moreover, if there's lordosis and you can't stand vertically, concealing the height loss with sneakers should have been avoided.
I believe it's not your intention, but it could be perceived as excessive advertising for the clinic.

As a reference, this is PRECICE, not LON, but it is a video that is calibrated using the nail diameter.

I must say from the very beginning that I both like and appreciate your technical and critical perspective.

First of all, our company avoids using the amount of elongation gained by the patients as an obvious advertising element. Because the amount of elongation can vary according to many factors. From my point of view, advertising should not be done on a multivariate factor. We are very modest in the optimum elongation rates that we recommend to patients anyway. We recommend 6 cm as the optimum -not maximum- elongation amount to our patients. If the patient has done some studies that can increase the amount of elongation, including some exercises, before the surgery, the patient's general physiological condition is good and if he/she manages to have a strict physiotherapy and exercise discipline throughout the process, we can revise this ratio as 6-7 cm or 7-8 cm. However, we recommend our patients not to aim higher than 8-9 cm in a single operation, whether they have been prepared or their physiology is ideal. From our point of view, less risky 6 cm is better than more risky 10 cm.

The aim of the before-after photos on the height scale is to show the amount of elongation that patients gain in the simplest and most concrete way. I do not know the technical details you use in your own measurements, but our height ruler has been prepared using the best measuring technologies and has an accuracy of almost 100% accuracy. Thanks to the strip fixed at the moment of measuring, the patient already sees the before and after of his own height with his own eyes. I can guess that the emoji we use to hide the patient's identity may cause uncertainty about the position of the measuring strip. Measuring with sports shoes is probably the patient's own initiative. I don't think that such a request has been made from him to show his height more than he is. If I'm wrong, he will correct this information anyway. But rest assured, the company never resorts to cheating or exaggerations for advertising purposes in such matters.

You pushed the limits -9cm- and succeeded in returning to your country in a healthy way. Congratulate yourself, of course I congratulate you, and always be open to constructive criticism. See you again...

Thanks for the answer. So the 90.12mm and ruler in the image below are already the corrected values for the magnification of the x-ray image?

I have checked the number of pixels for each length and it appears that unlike the previous x-ray image without the ruler, this image has been corrected for magnification.

I will forward your measurements and comments to the relevant personnel/unit and I will share their explanation here. However, as I said, we do not use the amount of elongation as an "obvious" advertising factor. If I see that your explanations make more sense, not the relevant personnel/unit's, I will not hesitate to make corrections here.
