Stryde vs Precice?

Edit Post

Fatigue Load(lbs)
Precice2   8.5mm        67
Precice2  10.7mm       118
Precice2  12.5mm        146
Stryde     10mm        167
Stryde     11.5mm      244
Stryde     13mm         320

when looked at this chart, you can estimate that even if Stryde 8.5mm was made, the fatigue load would  be probably less than 100lbs.
And with the fact that P2 8.5mm nail's weight bearing restrictions is even 50 lbs(24kg), Stryde 8.5mm would be around 70 lbs or so at most.
For adult women it will be difficult to walk unaided with this weight limitation.

Thanks for the info..hmm..but if I do end up with 8.5 mm and around 97lbd weight (right now) doesn’t that mean my load on the crutches can be less too? What’s the minimum time one can walk normal with stryde (normal as in no one can tell) if there is a lot of luck n no complications..? Is back to normal in 4 months  a possibility if J have a good diet, PT etc

Hi Ayesha, from the few diary's that I have read regarding the Stryde nail; it appears that by the conclusion of month 4, patients are walking pretty well with slight limp albeit; however they are beginning to see the "light" and enjoy their new height.  I detect that within the 5th month; a typical Stryde patient is doing quite well with their walking, assuming they did not length beyond 8cm in femurs or 5/6cm in tibia.   Being able to weight bare throughout the CLL process really does wonders in keeping knee straight and the back straight vertically.   In fact, other machines such as the gravity bike and a swimming pool are in place to simulate a quality gait movement and weight bearing since the earlier Precise nail is not strong enough to hold more than 50/60 lbs per leg.   I hope you are able to leverage the Stryde nail so that you may better tolerate the process and get back on your feet early.

Is that per-leg or across both legs?  How do we map to weight barring limitations?

I had (have!) Precice 2.2 nails in my femurs, and my weight limit pre-consolidation was 75lbs/leg (150lbs total).  I'm actually curious to know what the likely weight limitation would be if I used Stryde in my tibias one day.

I think you had the largest P2 nails. Was it very problematic to have used them? I'm probably going to need a smaller nail which means I can only weight bear 50lbs per leg which is quite scary to imagine.

That’s for both legs. How was your experience with precise? What doctor did you go to? How long post surgery were you walking normal like nothing happened?

The weight bearing capabilities of stryde will allow for a more comfortable and quicker recovery.  The smallest Stryde nail is 10mm which might be too big for petite females, but might possibly fit if you do femur, definitely not tibia.  As a point of reference I am a 54kg male and had a consultation to use the 10mm stryde nail for my tibia.  My tibia's bone canal wasn't big enough as at its narrowest point as it was only 7.5mm wide but my dr. said that part could be reamed to fit in the 10mm nail.

Its crystal clear that hes trying to market you

Dont do it from him 10000% dont. No other doctor has ever done this, they follow the nail and they dont improvise because we're talking about a person's livelihood here, not lego building

It’s per nail

a person stand on one leg when walking

To be Full weight bearing, One nail must be able to support whole body weight and force of stepping which will add even more weight
This is the reason why weight limit is lower than fatigue load

Nail in tibia has to support more weight than nail in femur

Cortex of female bones are much thinner than male
Even when canal is bigger, thin cortex will be difficult to ream

I did ~6.5cm femurs with Dr. Paley.  My details and experience was very similar to Purushrottam's, although my consolidation took a little longer and I had a lot of swelling the first couple of weeks.  (Sadly, none of the pain drugs helped with swelling pain!)

This is obviously not an easy thing to go through, but my experience was better than some of the other patients I met.  I knew I'd be useless for a few months so I had shows and games lined up that I'd wanted to binge through.  I also had the benefit of knowing people in the area, so I had a pre-existing support network to help with things.

I've considered going back to do the tibias, although the max is 5cm, and I don't want to push my luck, so I'd probably aim for just 80% of the max (4cm?) -- obviously a lot of money for not as much gain.  I think the weight bearing limitations of the old rods would have sucked, so I'm curious to know what they'd likely be like with Stryde.  (...Was that ever clarified?)



My advice to anyone considering this:  make sure your affairs are in order for being stuck and helpless for a few months, stretch as much as possible beforehand (I know Paley said this doesn't make a difference, but his staff will tell you otherwise) and use the walker as soon as possible;  getting out of the wheelchair makes a big difference, both physically and mentally.  (The last part may not be as relevant with Stryde, I dunno.)
