ST&G RidgeFlex Ankle Joint

Product information


Continuous Fiber Elastomer Technology - CFET. The RidgeFlex Ankle Joint represents optimal balance between flexibility and rigidity due to the utilization of a proprietary material called Prepalon®

  • Prepalon is a continuous fiber and elastomer blend technology (CFET)
  • The use of flexible elastomer provides optimum tear strength, preventing fatigue failure
  • Continuous fiber blended within the elastomer provides structure and rigidity, preventing the joint from stretching
  • This technology eliminates the need for strings which do not provide any support in rotation or A-P movement
  • Material technology allows for bold concepts which led to the creation of the tendon design. The tendon design offers a smooth movement while providing proper support in the sagittal plane and rotational control
  • Combination of flexible elastomer and continuous fiber blend for rigidity allows for optimum balance of smooth movement and rigid support
  • No need to compromise the tear strength by using a higher density elastomer for more support. Higher density in elastomer means weaker tear strength, thus compromising the structural integrity of the joint
