Precise 2.2 with Dr Debiparshad — June 2021

Thanks! This has been one of my biggest concerns with ambulating with the Precice. That's great to know.

Worth noting a few things:

1. Your legs from the hips down are about 1/6th of your weight.  At 160lbs I was only putting about 135lbs total on my legs, and per leg that’s about 65lbs.  Weight below the femur is not weight that is being put down on the femur itself.

2. precise 2,2 is a lot stronger than its specs say it is.  You can easily put 80lbs per leg for short periods of time even at full extension and be fine.  It’s twisting and turning and stepping motions as well as major impacts that cause deformities usually, most of the time by putting all your weight on one leg suddenly, such as when walking or jumping.  Precise 2.2 and Stryde have different weight limits but the construction and way this weight is considered is very different between the two.  If Stryde had only the same weight bearing as Precise, then Stryde would actually be less safe than precise for static two leg weight bearing.  Dr D and his PT Mike both explained that to me a few times.  In a way Stryde is actually more “on the mark” about how much weight it supports… a few pounds over and it’s dangerous.

3. The nails get much weaker as they extend.  At 0mm extended they are probably more like 100lbs per leg and fully extended much closer to the states 50/75lbs per leg.  You need to be extra careful once you go past 7cm and spend less time standing and as much time as possible laying or sitting until consolidation.  I for one only use the walker to go to the bathroom, otherwise it’s wheelchair everywhere.  Much safer during consolidation.

Some people start using crutches instead of the walker but IMO tight muscles make your coordination terrible so the walker is much better, much safer.  Only issue is that I’m so tall now that the walker on the tallest setting is still a bit short for me, but it’s still usable.

The only thing I don’t like right now is how dark my scars are, even if they’re small.  I know they’ll go away in time but they are very dark and by the time they heal they’ll have to be opened up again to remove the rods.  Starting to use a scar removal cream to see if it can at least get rid of the IT band release scars so I can wear shorts in public in the next few months.

The point about extended nails being able to bear less weight than unextended ones is very insightful. You already got past the toughest part of Precise. I am excited for your recovery!

Thanks for these insights, Hobbitman! I'd consulted with Paley / Robbins a few weeks ago. I weigh very close to what you do (160lbs) and my bones can also only fit the 10.7mm nail. I'd asked the same question to Robbins about standing on the nails, and he unequivocally said I can't even stand at that weight with the 10.7mm nail, even for a few minutes. So it's a bit conflicting to hear this, but also good to know that you've actually been able to stand.

I also had another question. Have you ever thought/worried about the possibility of fracture post nail removal? The recent occurrence with DreamerLL has me worried. I'm sorry for asking such a morbid question, but just wanted to get more thoughts on this.

Would you ever consider doing precise 2.2 on the other segment in India? I wonder because it seems like a cheaper option with the same nail

I wish maybe the mods could collect all the advice on how to manage being in a wheelchair the whole time during LL
