Component Review: Tamarack Flexure Joint Caps for Hinged AFO’s

Have you ever wanted to hinge a brace yet maybe not do it right away? Tamarack has come up with a pretty neat way to add Flexure Joints on the outside of an AFO.  The Tamarack Flexure Joint Caps also allow you to be a little more creative with an AFO designs. They have a few neat AFO designs on their blog and I have a couple pictures of what I have done with them. I think it is a neat idea and a very clean option for fabrication. I really like being able to have a very intimate fit around the malleoli yet have the articulation. Here is a dorsi-assist AFO that I did for a child with neuropathy.

Here is a picture of a unilateral upright dorsiflexion assist AFO.  The little girl I made this AFO for had a stroke but has gained a great deal of strength and now only needs a little boost for her dorsiflexors.  The AFO had to be pulled in two sections and joined with a chicago screw and then a Flexure Cap was placed right on top of the joint.  I have not fit it yet but it looks as though it will work.

  1. Thanks for writing this blog post, Brent!

    We’re happy to announce that the Tamarack Flexure Joint Caps are now available for large and medium joint sizes, in either natural or black color options. Visit our website ( or contact your preferred O&P distributor for more information.

    • Good to hear. It is a great product! Any chance the pediatric size will be next,

      • Unfortunately, the pediatric size Tamarack Flexure Joint Caps are probably a ways out from production. Due to the size of that joint, it’ll be a much greater design challenge than the medium & large size options.

        We know that the pediatric size option is desirable, and will keep everyone posted with any scheduled updates to the product line.

  2. Hi Brent, I’m not sure if I’ve mentioned it to you in our previous correspondence or not, but the Tamarack Flexure Joint Caps are now available in large, medium AND pediatric sizes. I apologize if I failed to mention that after we introduced the pediatric size, since I know you expressed interest early on. Thanks again for your support and please contact us anytime with questions or feedback. Great blog!
