Definitions

  • the present invention generally relates to ankle supports and, in particular, to a multi-layered ankle support having a first layer providing structural stiffness to the ankle support and a second layer having an adhesive backing for adherence to the skin.
  • a ligament is made up of multiple strands of tissue, similar to a nylon rope.
  • a sprain results in tearing of ligaments, the tear may be a complete tear of all the ligaments or a partial tear in which only a portion of the strands that make up the ligament are torn.
  • the lateral ligaments of the ankle are by far the most commonly injured. It is estimated that lateral ligament sprains make up approximately 85% of all ankle sprains. Typically, the lateral ligaments are injured during an "inversion" injury to the ankle.
  • An inversion injury occurs when the foot is roiled inwardly in an excessive manner thereby causing damage to the lateral ligaments.
  • another problem caused by ankle sprains is the increased risk of re-injury. Once an ankle has been sprained, the stretching and tearing of the ligaments leads to instability in the ankle that commonly results in re-injury. It is estimated that spraining an ankle may increase the risk of re ⁇ injury by as much as 40-75%.
  • ankle supports and braces are currently available in a multitude of shapes, designs and materials which attempt to prevent ankle sprains and re-injury by providing additional lateral support to the ankle.
  • prior art ankle supports fall within one of two broad categories which are discussed in further detail below.

  • Another disadvantage of this technique is that if the plurality of tape layers are applied improperly, the taping may cause interference with proper blood circulation.
  • Still another disadvantage with conventional ankle wrapping techniques is that the layers of tape cannot be applied in a uniform manner which results in irregularities in the degree of support, and the direction of support, provided at different locations in the

  • These "rigid" braces contain at least one rigid part constructed from a thermoplastic material, metal or some other rigid material.
  • the rigid piece or pieces of the brace are normally arranged near the medial and lateral malleoli and serve to minimize the inversion and eversion movement of the ankle.

  • the total length (i.e. I T1 , I T2 ) of the first layer 12 and second layer 24 is selected according to the height of the person using the support. Specifically, to obtain optimum performance and support, the total length of the first layer 12 and second layer 24 are selected such that during use, a terminal top edge 37 (Fig. 5) of the second layer 24 terminates about 4" to about 6" above the center of the medial lateral malleoli "M".
  • a table is provided below which provides the preferred approximate lengths of the first layer 12 and second layer 24 relative to the height of the person using the support.
  • the ankle support 10 is applied to the ankle 38 as follows. First, the peel away release strip 44 is removed thereby exposing the adhesive layer 72 on the bottom surface 28 of the second layer 24. Then the ankle support 10 is applied to the sole of the foot under .the heel area 42a as shown such that a central portion of the ankle support is arranged under the foot and equal portions of the ankle support extend upwardly along each side of the ankle. Once the support 10 is applied, the user firmly presses the support against the skin such that the adhesive layer 72 on the second layer 24 securely attaches the support 10 to the ankle. The enlarged end portions 14 and 16 of the first layer 12, and the enlarged end portions 30 and 32 of the second layer 24, partially extend around the ankle to promote secure attachment of the ankle support 10 to the ankle.
  • end portions 14, 16, 30 and 32 do not entirely wrap around the entire the circumference of the ankle.
