ShearBan Testimonial – Chainsaws and Body Powered Prosthesis Straps


Paul Davis from Minneapolis, Minnesota USA writes (5/26/2015),

We have lived in a rural setting for 25 years.  We supplement our heat with a high efficiency wood burner.  Several times each year dead trees are felled to be cut into the appropriate size for splitting and firebox fit.  I am an AE amputee with a shoulder fusion and wear a body powered prosthesis with a figure eight harness and number 7 terminal device.

I am the sole operator of our two chainsaws.  Historically, after several hours of chainsaw work, I had developed an open and large surface wound/blister above my right clavicle.  With limited sensation from a brachial plexus injury, the significant abrasion goes unnoticed until I disrobe.

I was provided with a product called Shearban several weeks ago after my latest injury removing 2 of 10 trees had mostly healed.  We placed the Shearban on the strap responsible for abrasion and after felling, removing the limbs, and sectioning 4 more trees, I am pleased to report no indication of enhanced or new abrasion.  An appreciated innovation!  Thank you.

We greatly appreciate feedback from our customers. If you have a ShearBan story to share, please email us or leave a comment below.


Blister Prevention for Podiatrists

Despite advancements in shoe design as well as sock and insole quality, foot blisters continue to plague active individuals who participate in individual and team sports activities. Even the most seasoned professional athletes are sidelined by blisters; a sign that education and embracing “outside the box” products and technologies are quite logically the missing links to finally eliminating foot blisters once and for all.

Australian Podiatrist, Rebecca Rushton, BSc(Pod) shares her professional experience with treating foot blisters in her new SlideShare presentation, Blister Prevention for Podiatrists. We do want to take a moment to note that this presentation is equally suited for the entire spectrum of healthcare professionals who treat individuals for foot blisters, calluses, and ulceration. Athletic Trainers, Orthotists, Pedorthists, Podiatrists, Therapists, and Wound care nurses are also involved in the care of athletes and patients who suffer from recurring irritation (hot spots) and blisters from footwear and various medical devices.

It’s not just amateurs and weekend warriors who hit the wall when blisters finally sideline them from the field or result in a DNF after training diligently for months to cross the finish line. Some of the biggest names in professional sports have been sidelined by foot blisters (as reported in the media):

Since 1998, Tamarack Habilitation Technologies, Inc. (Minneapolis, MN USA) has sought to help healthcare professionals and athletes resolve nagging foot blister issues through the development of the company’s patented low friction interface technology. ShearBan, a product most commonly known in the O&P industry, is available in sheets and precut patches to address friction & shear in footwear, insoles, and medical devices. 6 years later, Tamarack introduced ENGO Blister Prevention Patches, the consumer-packaged equivalent to ShearBan in the sports medicine and consumer athletics marketplace.

With the support of healthcare professionals and consumers around the world, Tamarack hopes to one day establish ShearBan and ENGO as household names in foot blister prevention and relief. But don’t take our word for it – order a pack for yourself. There’s nothing to lose (the product is guaranteed!) but the memory of painful foot blisters!

Choosing the Optimal Patch Size with GlideWear or ShearBan

Whether you’re trying ShearBan (self-adhesive PTFE sheets & patches) or GlideWear Prosthetic Liner Patches (2-ply silk-like shear reducing fabric) for the first time or are looking to optimize your patch size and placement for maximum performance and cost savings, SIZE does matter. This post serves to provide guidance and considerations in choosing the correct patch size for your individual need.

New from Tamarack Habilitation Technologies, the GlideWear Prosthetic Liner Patch is indicated for lower limb amputees who experience discomfort or skin breakdown on their residual limb due to interface pressure and shear between the socket, liner, and skin.

The GlideWear Prosthetic Liner Patch is currently available in two sizes:

Small (standard) – measuring 2.5 inch x 4.75 inch (6 cm x 12 cm)GlideWear Prosthetic Liner Patch

Large – measuring 4.5 inch x 7.5 inch (11 cm x 19 cm)

In choosing the correct size for you or your client’s needs, consider starting with the small size, which is optimal in MOST applications. Whether you’re using the GlideWear Prosthetic Liner Patch to relieve or prevent discomfort and skin breakdown on the patalla, popliteal, distal anterior tibia, or fibular head, we only recommend using a patch that’s slightly larger than the area of concern.

If the small patch provides insufficient coverage due to limb size/volume or wound size, only then do we recommend selecting the larger patch size. Wrinkling is also reduced or eliminated when patch size is optimized and not exceeding the size of the limb.

Keep in mind that prosthetic liners are used for suspension, so the least amount of spot reduction of “hot spots” or pressure areas is the goal. 



ShearBan, another friction & shear interface technology from Tamarack, is also intended to provide friction & shear reduction in areas of concern and not throughout the entire device. Because ShearBan’s ultra-slick PTFE surface is slippery as ice, the material should be used to spot relieve friction & shear wherever hot spots, blisters, ulceration, or callusing appears.

ShearBan is available in 8 inch x 12 inch sheets for custom trimming as well as 1.75 in x 2.75 inch oval patches for easy placement on footwear, insoles, and medical devices.

Study Findings Discuss the Role of Rocker Soles in Reducing Ulcer Risk

There has been much discussion recently in a host of publications about the role of pressure and shear in the treatment and prevention of foot ulcers. Emily Delzell’s article, The role of rocker soles in reducing ulcer risk (Lower Extremity Review, August 2011) shares findings from a recent study, suggesting that rocker soles effectively reduce peak plantar pressures in patients at risk for diabetic foot ulceration.

Delzell reported findings from earlier studies, suggesting that rocker soles reduce pressure under the forefoot, and specifically under the metatarsal heads, by 30-50%, although it is unknown what amount of pressure reduction in footwear is necessary to truly help heal and ultimately prevent foot ulcers.

Not discussed in the article, is the role of shear forces in the genesis of skin trauma. Increasingly, shear is being discussed at healthcare conferences, and through special interest groups, such as the National Pressure Ulcer Advisory Panel (NPUAP). The shortcoming of shear, at the present time, is the inability to accurately measure shear forces underneath the foot. Still, the prevention and treatment of foot ulcers should include consideration of shear stresses, particularly under bony prominences where shear can be especially damaging.

Complementary to rocker shoes, total contact casts, and other pressure offloading devices, friction and shear interface materials, including ShearBan, provide additional margin of safety from skin breakdown. When applied directly to footwear or orthopedic devices, opposite a troublesome hot spot, blister or foot ulcer, ShearBan has proven effective at helping to heal existing skin trauma, while preventing future occurrences.

New ShearBan Flyer

The latest ShearBan flyer is now available on Tamarack’s website:

The most exciting change that recently took place is that ShearBan Rivet Cover Patches are now packaged in 138 piece packs, instead of 120. The 15% increase in patches comes to you at no additional charge. Rivet cover patches are ideal for covering hardware on AFOs and upper extremity devices. They provide a clean, cosmetically appealing finish to any thermoplastic or carbon fiber device. Rivet Cover Patches are manufactured with latex-free, low-friction material that eliminates abrasion/rubbing and friction, and easily apply to nearly any material with the self-adhesive backing.
