PDE-Springs-3-Angled-WebLarge-rgb

The PDE™ orthopedic spring system is a modular AFO spring for composite brace designs. This simple and reliable ‘plug and play’ system provides the ability to adjust alignment in both the footplate and upper cuff after the brace has been fabricated. Dynamically adjust external, internal, plantar & dorsiflexion alignments as well as easily change spring stiffness and length.

  • 9 Flex Spring Choices
  • Available In 3 Lengths: 200mm, 250mm, & 300mm
  • Modular Design
  • Low Profile
  • Adjustable Alignment
  • Designed For Weight Offloading
  • Clinically Proven
  • Made in the USA

CHOOSING THE RIGHT SPRING Guidelines for Choosing PDE Spring Lengths

fabtech-PDE-brace-featured_Orthopedic-3-sizes-02

Because every patient has unique needs there are no specific weight limitations that aid in spring choice. Choose the category based on your patient assessment. As a general rule you want to use the longest spring system your cuff design or patient height will allow. In an Orthopedic case where you are trying to control and limit motion to control pain, we recommend using a higher category spring in the beginning.

200mm length springs

A good choice for shorter patients or when maximum PTB unloading is desired, as the largest area cuff can be utilized.

250mm length springs

Fits the averaged sized population well and can be used with the PTB cuff design and anterior cuff design.

300mm length springs

Generally used with tall patients, or when wanting to provide a small anterior cuff design as common with the IDEO designs.

SPECIAL NOTE:

Category number three (3) spring are the most common selection and a great to start your evaluation. From here, up/down spring category is based on what works best for the patient. Our simple four bolt system makes changing the spring quick and easy.

Recommendation: PDE Fitting Kit

Get it right. Get the Fit Kit.

When building a custom device, it’s always nice to have options. That’s why we created the PDE Fitting Kit.

Try different categories of springs on your patient until you find the perfect fit!

Then just replace the the parts that get used so you always have a full set of springs & hardware.

Fit Kit Contents: 5 PDE Springs (One each PDE spring category 1 through 5), mounting anchor kit, alignment shim kit, adhesive dispenser and adhesive.

CHOOSING THE RIGHT SHOE Basic Guidelines for Choosing Shoes

Ideal shoe: 3/8” Soft cushioned heel, Soft sticky tread, Minimum 1⁄2” toe rocker, Wide toe box

  • Your patient will need to buy new shoes to fit over the Brace. DO NOT use old, worn-out shoes.
  • We find a shoe size larger and wider works best.
  • Ideally have your patient buy shoes after they receive the brace.
  • Look for shoes with laces that reach down as far to the toes as possible and shoes that are deep and have adequate width to accommodate the brace thickness.
  • The shoes do not need to be expensive; ordinary tennis shoes work best. Sketchers brand have been very successful with our customers.
