France and Germany, get ready…FH Orthopedics, developer of the Elastic Spine Prosthesis (ESP), is on its way to a hospital near you. The company has recently signed two new agreements, one with France Rachis and the other with Via 4 Spine in Germany.

They are also expanding in Spain. Wonder when Dr. Clavel will be upgrading to this disk?

So how many of you has this implant on your spine? Are they really good as the fact show?

Surgery was on November 08, 2016... so I am 4 months 22 days post-op. Even though I have severe atrophy (getting better every day) I feel so good right now overall. I have no pain in my spine, facet joints or nerves. My surgery was 100% successful, and I have been given a greater than 99% chance of making a full recovery with no restrictions by the end of May of 2017.

I'm wondering if they'll ever do a study showing the effects these newer discs have on the facet joints. I know that the Activ L did one that was pretty cool:

Dr's using LP-ESP
 

I am most interested in this disc. Is there a list of Dr's that use this disc? I only know of Dr. Rischke.

Dr Desai in Germany -- http://www.dfk-koeln.de/leistungsspe.../das-team.html -- click the TRANSLATE BUTTON that pops up.
He prefers the LP-ESP but will do an M6 implant if that better fits a person's anatomy (x-large vertebrae in very tall men) at time of procedure. He charges around $15k Euros for one level and $20k Euros for two levels. Complete package cost excluding travel and hotels/food after being released from the hospital. I've spent months researching various discs. Those who stumble upon finding and researching this one end up getting it. Its awesome!

Send the CD with MRI to the address and include email,
symptoms, past treatments, etc

Thanks for the info LHerm & nasakido

The LP-ESP seems to be one of the best choices out there at this time... I'm shocked the company isn't doing more to advertise its growing popularity. The last published numbers for sales was from about 2 years ago and is only 6k. While the M6 has like 10x that number.

Fatigue and wear tests

Wear tests were conducted in a 3-axis motion simulator according to the following protocol (Fig. 7):

• Series of 10 million cycles of flexion, extension, and lateral tilting
• Frequency = 4 Hz
• Loads of 135–1,350 N
• Inclination of the prosthesis at 45° to reproduce the sagittal orientation of the disk in functional situations
• In a demineralized water bath at 37 °C

Am I the only one concerned that a load of 135 N isn't very much? I mean sure, if they do 40 million cycles at 1,350 N... Highly impressive. But no indication of what the distribution of those force ranges were.

Most of the time, for fatigue tests you'd read that range as the minimum load was 135N and maximum was 1350N and that each cycle went from minimum to maximum. They didn't specify that, but that's the way I report fatigue test parameter when I perform them on the product (non-medical stuff) that I test. If that's the way to read it, picking a 135N minimum load was the right thing to do as that's way too low for a normal disk to really see except in unusual circumstances; thus the test would be conservative on that end.


On the other hand, I only glanced over the report and saw a few bone-headed mistakes that makes me wonder about the report. Fournier transform is called out in the spectroscopy section when the correct term is Fourier Transform or commonly FT by those who use it frequently. Might be a simple misspelling or it might be that the report was written by someone who's compiling data that they don't understand. If it's the latter, there might be hidden assumptions throughout that aren't necessarily the way an expert in that field might have reported it.

Thank you Anna. Good point that I hadn't considered was that the disc was always under compressive stress and just that it cycled up to 1350N at 4Hz... Which I agree would be a pretty good stress test if they did 40 million cycles.

I find it interesting that the studies on the LP-ESP state that it passes a number of biocompatibility tests.


But it also mentions that after 10 million cycles in a saline solution...



"The tests looking for salted out or released matter showed
the emission of\1 mg/kg methylene diphenyl 4-4 diisocyanate and of 64.9 mg/kg of 4-4 methylene diamine. These
results are consistent with the data in the literature "


Wikipedia suggests that MDA is a suspected carcinogen. And:


"The Occupational Safety and Health Administration has set a permissible exposure limit at 0.01 ppm over an eight-hour time-weighted average, and a short-term exposure limit at 0.10 ppm"


So to me - 64.9 mg per kg of saline... That seems like a lot.

Hey I'm getting the cp-esp as well and this is a glaring issue. I know that you've already gotten the cp-esp. May I ask why you overlooked this issue?

Sure:

1. Lesser of all evils - other discs have plastics, or just as bad maybe - nickel.
2. I take supplements already that should substantially improve my immune system
3. Won't live forever - a judgment call as to the risk of cancer versus health impact of being inactive

I looked through your posts, you make intelligent choices and arguments.

I'm about to turn 32 and require c5-7 replacement, it's causing severe canal stenosis.

Given that I will have these discs in me for another ~30-40 yrs, that'll mean exposure to the toxins released by the esp discs for similar time. I'd imagine my risk of cancer will increase due to the toxins, perhaps I should op for fusion instead. the prospect of adjacent segment disease/more fusion is more preferable to cancer/chemo.

Thank you! That is one of the few gifts I have... I'm very analytical.

I don't want to influence you either way... I will only say that I was in a similar spot, and although I'm older... I came to grips that the risk / reward was a no-brainer for me.

It took some time for me to come to that conclusion though... And it really is the "trifecta" of the items I quoted... Supplements (vitamin D among other things)... Really have been shown to have dramatic impact on various cancers.

Oh and one thing I forgot to mention... Do you realize how much plastic you're already consuming every year?

https://qz.com/1644802/you-eat-5-gra...stic-per-week/

That was the final straw for me... I just wasn't going to immobilize two vertebrae forever, causing other spine problems (I already have too many)...

Well all things considered
 

Because I am going back for a revision of my C6-7 due to HO behind my M6-C, I am hoping that Dr. Clavel will use an ESP.

I'm MUCH more confident in the LP-ESP vs the CP-ESP.

I'm reasonably astute, not a medical doctor or a prosthetic engineer... But I don't see any other device as being nearly as well designed. And while it doesn't yet have the implantations that the ProDisc or the M6 have, it does have many years of history.

The CP-ESP has a lot less... And I worry a bit about the elastomer really holding up to 30 years of life... I held a CP-ESP in my hand and it is just tiny... And the elastomer even smaller as you can tell by the imaging.

Still think the CP-ESP is probably the right one, but I'm just a lot less confident in it than I am in the LP.

Hello Jack

I am wondering what makes you confident in LP ESP?
I am concerned about life span of its silicone nucleus.
Manufacturer did some accelerated aging tests at elevated temperatures, and claims that the prosthesis will outlive the person. But I googled the info on silicone longevity and I didn’t find any silicone part that would last more than 10-20 years. Everyone knows that in old cars all rubber parts are trash in 15-20 years for sure, and especially those bushings that absorb shocks in control arms etc.
I am wondering if you considered this aspect?

Thanks

I'm paranoid.

I consider everything :)

It's actually a curse.

Bionate 80A is in a family of polymers that has been used in medical applications for close to 20 years. If this gets me 20 years pain elimination, without impacting adjacent segments like a fusion would... I wouldn't have a major issue with going in for a surgery to replace it in 20 years.

In 30 years maybe we'll have lab grown human discs from my DNA that could be popped into my spine.

In the meantime I see the LP-ESP as the best chance of having a long term positive outcome. No fusion, or 3 d.o.f. ADR, or anything else comes close, in my mind.

On and the silicone inner core... Silicone has been in use in the medical field for like 50 years?

I expect them to last the rest of my life, but if not, by then maybe there will be even better options with better surgical techniques.

I'm playing the odds... I HAVE to do something about my chronic discomfort and pain. And from my perspective, the odds on every other option just don't look anywhere near as good as the LP-ESP...

Assuming you pick a very experienced surgeon.

You have to do what is best for you, don't forget that.....
 

It has been a while since I have made a post here on this forum. But, since I made a 100% recovery after surgery in November of 2016, I have been very, very busy. Since I had the LP-ESP disc put in my L4-L5 and L5-S1 it took me three years to become absolutely pain free. My recovery also included overcoming severe atrophy and damaged nerves due to my injury, but the nerves healed completely toward the end of 2019, thankfully. I really thought they would never heal. I tell you what, this was the best decision I could have made. I have my life back and then some. I find I have no limitations with the life style I live either. I finished our basement remodel, planted a ton of trees on our property, and enjoy work. I am so thankful that God led my wife and I to this disc option. Dr. Rischke was a blessing too. Him and his wife made a great team. Honestly I was not sure what to expect, but I did not want to live with the pain and being bed ridden the way I was. In the end I trusted the knowledge I had gained through all my research, trusted my wife, and trusted God with my recovery. It was not easy for sure, but ultimately you have to do what you feel is best for you, and for your loved ones. I know my wife and children wanted their husband and father back. My wife and I now have four children and feel very blessed for what we have. Life is hard and is not easy, but we make the best of what we have been given. I hope the best for you. Do not give up, ever.

Here here!
 

Jack,
Well said and to the point. I would rather try something more natural and less evasive one. You can always do fusion later. Fusion made my life a misery. It did not help my pain at all!!!!

Nathan,
Thank you for your story and for sharing your experience.
I wish you all the best. I had a consult with Dr.Rischke too. He dies surgery now at Clinic Bel Etage with Dr. Schmitz who is also an excellent surgeon, but post Op follow up has been zero. That is my only complaint.
I got a reply from my first ADR surgeon and he said said my placement and the execution looks good.
Still, I have an assessment coming up this Thursday with a surgeon on the east coast. I want to keep an eye on this. I would like to jave another CT this fall. That will be a year out and see how the Cp-Esp is holding g up ans also the level under it. That is where still have an M6.

Life Back

That says it all man , congrats ! Thanks for the update !
