Össur's Latest: The Pro-Flex Prosthetic Solution

Össur, a global leader in prosthetics, is an incredible asset to the field as they constantly push the boundaries of what is possible. The 47-year-old company dedicates an enormous amount of time and resources towards innovation, and Pro-Flex is a result of that.

What is Pro-Flex?

Össur recently released the Pro-Flex, a prosthetic foot that features push-off using mechanical levers, which closely mimics normal biomechanics. The mechanically-powered push-off allows the prosthetic wearer to experience better ankle motion and power compared to conventional carbon fiber feet.

Mechanical Push-Off

The mechanical push-off is the Pro-Flex's unique selling point. This is because the levers used in the Pro-Flex, connected through pivots, are a first in the industry. Levers are perfect for lifting and moving heavy objects. This is how the Pro-flex is able to convert a small force into a large force and offer push-off.  By using the additional 27 degrees of ankle motion in the Pro-flex, its levers are also able to provide the wearer a wider range of ankle motion. 

This prosthetic foot is definitely a mechanical marvel pushing design boundaries!

Less Stress

Another great thing about the Pro-Flex is that Össur engineers incorporated three levels of carbon plates to reduce the load and impact you may experience when you wear your prosthesis. This technology indirectly prevents unnecessary stress on your sound side leg while walking.

To further understand the gift of this technology, observe anyone as they walk. You may notice that the knee tends to thrust outwards by as much as a centimeter when full weight is loaded. Having a significant outward thrust results in knee strain, especially for prosthetic wearers.

This Pro-Flex feature of three levels of carbon, also reduces that outward knee thrust on your prosthetic side, limiting the incidence of osteoarthritis down the road, a situation that plagues many amputees.

Not Just a Foot Shell

While most prosthetic foot shells seem like an afterthought, Össur's Pro-Flex is several leagues superior. Its foot shell offers a "grippy sole" which makes walking barefoot on wet surfaces possible. It also features a more natural shaped arch or foot print so it fits better inside your shoe. In fact, Össur designed the foot shell to adapt to different types of footwear, so you don't have to choose between hiking or running shoes.

Össur went a step further with the Pro-Flex's foot shell, as it features defined toes that you can paint, should you want to do so. 

Pro-Flex in numbers

Users of Pro-Flex can experience the following, over a conventional carbon prosthetic foot:

  • 82% increase in range of ankle motion
  • 93% increase in peak ankle power
  • 11% less load on the sound side, reducing the incidence of knee arthritis
  • 15% reduction on knee Varus moment

  • PRO FLEX PIVOT IS INCREDIBLE. CAN’T TELL THE DIFFERENCE BETWEEN GOOD LEG AND PRO FELX PIVOT – IT FLOATS ON A SINGLE SEAL IN X SEAL RING. OSSUR UINITY SYSTEM IS INCREDIBLY NIMBLE – QUICK TURN ON PIVOT AND SO COMFORTABLE JUST LIKE MY GOOD LEG.

    TWO MORE USERS ARE WAITING – THIS TECH IS NEW TO THE CLINIC. AFTER THE ACHILLES ELEMENT IS STRETCHED, THERE IS A RELEASE/RETURN HOLLOW, CLICK SOUND LIKE A DAMPER NEW OSSUR NITY, PROFLEX PIVOT
    INCREDIBLE. CAN’T TELL THE DIFFERENCE GOOD LEG AND PRO FELX PIVOT WHEN LEG WHEN WALKING – IT FLOATS ON A SINGLE SEAL IN X SEAL RING. INCREDIBLY NIMBLE – QUICK PIVOT TURN. SO COMFORTABLE.

    WHEN WALKING, AFTER THE ACHILES STRETCH, THERE IS A A RETURN CLICK (DAMPER POT?). I WORK IN R&D AND ENGINEERING EXPERTS WORRY THAT CLICK SOUND INDICATES SOMETHING IS FAILING. HAVE PRO-FLEX USERS HAD ANY EXPERIENCES LIKE THIS?

  • This foot is the Cadillac of feet. It’s so low impact if feels like you are walking on a trampoline. Comfort level is a 10. It can only minimize the long term affects of knee, hip and back issues. Makes you feel extremely light on your feet. You will not notice the weight because of the functionality. The ROM in the ankle makes walking effortless. I’ve been using it for about 3 years.

  • When will the product be available for Medicare patients? I am a Kaiser client

  • The additional ankle motion allows for easier stair climbing. You’ll need to check with your Prosthetist regarding cost.

  • I have been using this foot for a little over 1 year. It was paid for by Comercial insurance. Lots of documentation from my prothatis and pcp. Overall it is better than most, worse than some. Pretty heavy, but you do get used to it.
