“String” Substitute Prosthetic Lamination Tip for a Below the Knee or Above the Knee Prosthesis

When I started as a technician in the Orthotic and Prosthetic field I always used a string that did not absorb resin.  The string served its purpose, but I ran accross this  tip from a technician that does great central fabrication work (Sunstone Lab for those who are curious).  The benefit of using a nysert as your string is that it becomes part of your lamination.  The results are phenomenal and structurally the lamination now is fully saturated and one piece. The other benefit of using this tip is that your string does not show through the outermost layer of lamination.

    Thank you for the tip. I watched you tying the string, and noticed how it pulls away from mold after you done cinching the know. Simple trick is, when you do your first pass of string over and under the other string, to do 3-4 passes, instead of one. This cinches strings against the mold as tight as you can pull – and they STAY IN PLACE due to higher friction between multiple passes. Then you simply finish the knot as usual.

    here’s another knot you can use. After becoming familiar with it, it’s faster than knot you use, and holds as well.
