Shock Pylons Summary

Shock Pylons Summary

John T. Brinkmann

1/19/2001

List Members: Here are the responses to my question about shock
pylons. The weight limits (which I did not mention in my original
question) have turned out to be more limiting than the clearance issue
in this particular case. The original question I posted pertained to
the availability of shock pylons with less minimum clearance than the
ICON or low profile VSP from Flex Foot.

Thanks to all who responded.

I am wearing an Endolite TT pylon that has a minimum clearance of 5
1/2. I hope this helps.

If you use Allurion foot with a century XX11 Total Shock with female
receptor and a proximal tube clamp adapter is only 8 1/4 tall for the
whole assembly. If you take out the proximal female tube clamp and add
a non adjustable tube clamp you may save 1/4. Also if you are using a
pin lock system the ÖSSUR 300 series Lanyard is only 1/2 build height
or the 200 series clutch lock with 4 hole is 1 to 1 1/4 or the 100
series rated up to 265lbs. is 1 1/4 build height and you get a male
pyramid socket attachment built in.

The Century XXII total shock provides rotation as well as shock in a
lower profile pylon- A good choice, and an Ossur(Flex-Foot, Mauch,
Century, Iceross liners) product.
Good luck, call if you have questions

I haven't compared the numbers, but what about an Allurion or Springlite
Adv.Low Profile with a Century 22 Total shock? I have good results with
all of the aforementioned. Todd CP

John,
Endolite North America has the TT Pylon which requires 125 mm 4 7/8)
from the top of the housing to the cut off point of the carbon fiber
pylon section. Please contact me at Endolite on 800-548-3534 and I will
be pleased to give you any additional information.

I don't know if this helps but for years I fabricated an internal shock
absorber. It requires a 2 layer socket with a 1/2 space. The space is
filled with a 1 firm, medium or soft density SACH heel rubber and the
two sockets are secured with a special strapping mechanism. Leaving a
shock capacity of about 3/8 and rotation between the 2 sockets of about
5 degrees
in each direction (a total of 10 degrees). I could fabricate it for you
sometime if you're interested. Just send me your finished socket.

Hi John
            Just a note to say Endolite has been supplying for many
years a Vertical shock pylon, with we believe to be a low profile, the
unit itself can be cut to a minimum height of 125 mm or 5 inches, this
allows limb builds as follows.

1) Clearance Base of socket to ground, 7 3/4 using the following
Components.
      TT-Pylon with vertical shock and rotational control,
            Advantage low profile foot, from springlite.
                  Tube clamp from Endolite.
                        Pyramid from Endolite.
                     This is including a 3/4 heel height allowance, and
a
shell for the foot.

2) Clearance Base of socket to ground, 9 7/8 Using the following
Components.
      TT-Pylon with vertical shock and rotational control,
            Endolite multi-flex foot,
                  Endolite multi-flex ankle,
                        Pyramid from Endolite.
                       This is including a 3/4 heel height allowance.

3) Clearance Base of socket to ground, 10 5/8 Using the following
Components.
          TT-Pylon with vertical shock and Rotational control,
                  Endolite Dynamic response foot, MK 2,
                        Endolite multi-flex ankle,
                              Pyramid from Endolite.
                        This is including a 3/4 heel height allowance.

            Hope this is of some help to you and please do not hesistate
to
give me a call at Endolite North America, 1-800-548-3534

        The TT-Pylon is 35MM carbon fiber, and has a weight limit of
264lbs, the unit comes in lengths 288mm and we have longer pylons
available, the vertical shock portion is controlled by way of a spring
and the rotational control is by way of a torsion rod, both of which can
be matched to the patients weight and activity.


John in answer to your question we have the Springlite foot called the
Lowrider which has a 2 1/2 clearance. We also have the Ohio Willow
Free Flow shock and rotational pylon that has a clearance of 6.5. We
also carry the USMC Ultimate Pylon which is also shock and rotational
and has a min length of 6.125. I hope this helps.
