Definitions

  • This invention relates to stabilization braces and more particularly to a support design which stabilizes the ankle and forefoot of the user at a desired neutral position.
  • supination of a foot combines inward rotation at the ankle, adduction of the hind foot inversion of the forefoot and medial arch elevation.
  • supination produces a medial (inward) movement at the talocalcaneal (subtalus) joint known as inversion as well as similar movement between the hind foot (talus) and mid foot (navicular) bones.
  • a foot that supinates appears to naturally favor the lateral region or outside edge of the foot.
  • a certain amount of supination is normal during the toe off stage of running, i.e., when the heel first lifts off the ground until the end of the step.
  • the lateral structures of the foot tighten which may rupture or avulse portions of the lateral collateral ligaments resulting in a "rolling over" of the ankle or ankle sprain.
  • pronation of a foot produces opposite foot behavior of the subtalar joint including adduction of the forefoot, eversion of the hind foot and dorsiflexicon. Basically, pronation produces a lateral (outward) movement of the foot at the subtalar joint known as eversion as well as similar hind foot and mid foot movements.
  • a foot that pronates appears to naturally favor the inside or medial edge of the foot. The foot naturally pronates to absorb the shock resulting from the heel hitting the ground. Excessive pronation increases the stress on the inside/medial portion of the foot which may lead to various injuries such as arch strain, heel pain, inner ankle pain and shin splints.
  • a first brace presents an elastic, sock- like body positioned in a compressive fit about the ankle and foot of the wearer.
  • a pair of torque straps is anchored to the body adjacent the distal (head) ends of the first and fifth metatarsals.
  • Each strap is then wound about the forefoot, heel and ankle and anchored above the ankle joint so as to present countervailing forces along the foot and ankle joint complex. These forces resist excessive movement of the foot and ankle from their normal, neutral position without precluding normal ambulatory movement thereof.
  • the brace design anatomically fits either foot about the heel, ankle and forefoot aspects thereof.
  • a first closure system which allows the sock-like body to be easily slipped onto the foot.
  • a second closure system maintains the circumferential integrity of the brace about the ankle joint region and presents anchor zones for the free ends of the bilateral torque straps. This structure allows the user to variably adjust the tension on these torque straps and thus the countervailing forces presented thereby.
  • a second brace similar in construction presents bifurcated ends at the end of each torque strap. These ends are respectively anchored to the material body adjacent the distal ends of the metatarsals and the heel. Each strap is then wound about the foot as above with the dual anchor zones enhancing the distribution of opposing forces along the foot.
  • a third embodiment again presents bifurcated ends at the end of each torque strap.
  • a first bifurcated end of each torque straps is respectively anchored to the material body adjacent the distal ends of the metatarsals with the second bifurcated end attached to the material body at the rear of the heel adjacent the Achilles tendon.

  • the closure system 200 presents a plurality of tabs 230 which are secured at one end along the longitudinal extent of the notch 210 on flap 130. These tabs have Velcro® fastener material 232 on the inside thereof. Complementary Velcro® material 234 is located along the extent of the notch 210 on the opposed flap 140. The engagement of each tab 230 fastener 232 to the complementary fastener 234 enables the user to adjust the compression of the sleeve 112 about the ankle joint region as the degree of overlap of these fasteners 232, 234 can be selectably adjusted.

  • These straps, 500, 600 are preferably made of a non-elastic material. However, I have found that the use of elastic material in a portion of the straps 500, 600, adjacent the anchor zones 550, enhances a smooth wrapping of the straps about the foot in a manner to be subsequently described. It is understood that the straps 500, 600 may be a single elongated strap anchored at 550 so as to present the medial 500 and lateral 600 straps or separate straps extending therefrom.

Abstract

L'invention porte sur une attelle de stabilisation qui présente un corps de type chaussette compressif pour un ajustement compressif autour de l'articulation de cheville et de la partie antérieure du pied. Une paire de bandes de force s'étend à partir des têtes de métatarse et est enroulée de préférence le long de régions opposées du pied et de la cheville afin d'apporter des forces compensatrices le long de celles-ci. Des premier et second systèmes de fermeture fixent le corps au pied et apportent un support périphérique à celui-ci. L'attelle résiste à une supination et à une pronation excessives du pied, de l'articulation de la cheville et des structures sous-jacentes. Trois modes de réalisation de l'attelle sont représentés, dans lesquels une extrémité des bandes de force est fixée à une zone adjacente aux métatarses ainsi qu'à des extrémités bifurquées liées à la zone des métatarses et une seconde zone espacée de celle-ci. Un troisième mode de réalisation présente des extrémités bifurquées liées à une zone adjacente aux métatarses et une autre zone à l'arrière du talon d'Achille, qui présente un mécanisme de verrouillage de talon amélioré.
