Definitions
- the present invention relates generally to ankle brace and, more particularly, concerns an ankle support which i fully adjustable to a wide range of sizes, for providing com pression and firm support for the joint and ligaments of th ankle, without affecting their normal function.
- ankle braces A typical prior art brace takes the form of a sheathe or stocking which is worn on the foot and lower leg. Some braces have made provision for selective tightening and adjustability, for example by means of laces.
- ankle braces do not provide effective support to the lateral ligaments in the ankle, and to get any support, they must be secured so tightly that pinching and interruption of dorsal flexion occur. Secur- ing the brace as tightly as needed for any meaningful support therefore would interfere with normal movement.
- ankle brace Another type of known ankle brace is a lace-up model with an elastic strap that fits over and around the ankle to provide elastic support for the ankle.
- the problem with elas- tic straps and the like is that they provide compression but very little support.
- braces in use today have little pockets that receive metal stays. They are used primarily for acute injur ⁇ ies, because they limit normal motions of the foot to an ex- treme degree and, if worn on a continued basis, can produce atrophy of the musculature in the region.
- an object of the present invention to overcome the disadvantages associated with ankle taping and prior ankle supports. It is a specific object to provide an ankle support which may be quickly and easily applied to and adjusted upon the wearer's leg, while offering a high degree of firm, inelastic support for the ankle joint, and not interfer ⁇ ing with normal movement and use of the joint.
- an ankl support is provided with an underliner having multi-directiona stretch which fits over the wearer's foot in the manner of sock and extends to a point above the ankle.
- a non-stretc lateral strap is secured to the underliner at a point below th ankle joint and extends upwardly to the top of the underliner where it is inelastically secured, with provision being mad for adjustment of its tension.
- a non-stretch medial strap i inelastically connected to the lateral strap therebelow. Th medial strap extends underneath the foot and up the opposit side thereof, and it is inelastically secured to the leg nea the top of the underliner, with provision being made fo adjustment of its tension.
- the medial strap thereby support the wearer's arch and, in combination with the lateral strap supports the ligaments of the ankle joint and provides a "hee lock", to limit and balance the lateral movement of the ankl joint.
- the underliner is provide with hook and pile closures which permit adjustment of its fi and the compression it provides.
- a second lateral strap i inelastically connected to the first lateral and medial strap near the location of the base of the fifth etatarsil.
- Thi second lateral strap extends upwardly and is inelasticall secured to the leg near the top of the underliner with provi sion being made for adjustment of tension.
- the inelastic se cure ent (and adjustable tension) of all straps near the top o the underliner is provided by means of a non-stretch ancho strap which extends about the leg near the top of the under liner.
- the first and second lateral straps and the media strap are secured at their tops to the anchor strap by means of hook and pile fasteners, and the medial strap wraps around the front of the ankle and over the first and second lateral straps, to aid in their securement.
- the hook and pile fasten- ers assure convenient and rapid adjustment of the ankle sup ⁇ port.
- Fig. 1 is a perspective review showing an ankle support in accordance with the present invention in its applied posi ⁇ tion on the leg of a wearer;
- Fig. 2 is a left side elevational view of the ankle support as shown in Fig. 1;
- Fig. 3 is a front view of the ankle support;
- Fig. 4 is a right side elevational view of the ankle support as shown in Fig. 1;
- Fig. 5 is a rear view of the ankle support
- Fig. 6 is a top view of the ankle support
- Fig. 7 is a perspective view of the ankle support in its open position, showing further details of various compo ⁇ nents.
- FIG. 1-6 illustrate an ankle support embodying the present invention, as applied to the right leg of a wearer.
- the support 10 would be provided in an opposite version (a mirror image of the version illustrated) for use on the left leg, and in several sizes (e.g., small, medium and large) of each version. As will be explained more fully below, after application, the support 10 remains in the position shown and will readily fit inside the
- Adjustments can be made quickly and easily, and usually, without removing the shoe.
- the main body of ankle support 10 is an underliner 20, which is made of neoprene.
- a closed-celled rubber is used because it will not retain bacteria, fungi or other organisms that could propagate.
- the underliner has a multidirectional stretch and provides warmth and compression for the wearer's ankle.
- the underliner is unique in that it has a heel cut-out 21, which allows the brace to fit into an athletic shoe or any ° shoe without affecting the lengthwise fit of the shoe.
- the widthwise fit of most shoes is adjustable, for example by ad ⁇ justing laces or wearing a sock of a different thickness, bu lengthwise fit is normally more difficult, if not impossible, to adjust.
- Ankle support 10 is somewhat unique in that it receives the wearer's foot from the front and is a front closing brace. It is closed by means of two components called the tibia or th calf closure device (22, 23) and the dorsal closure device (24, 25), which is below the bone of the ankle.
- the numerals 22, 23 0 indicate a conventional hook and pile closure device, the hoo and pile elements being indicated as 22 and 23, respectively.
- the lower or dorsal portion of the underliner similarl includes a hook and a pile closure device 24, 25.
- the brac components are preferably secured to the underliner by stitch ing.
- the dorsal section again provides stretch and is applie 0 by stretching the hook component 24 over the underliner an affixing the closure device 24, 25.
- the combination of the adjustable upper and lower clos ure devices provides a very wide range of fit for many foot types.
- the adjustment of the two closure device 5 relative to each other accommodates a wearer with a very thic or very wide lower leg and a thin or wide foot, and it provide for many other variations of calf size in relationship to foo size. It also does not interfere with normal dorsiflexion or plantarflexion of the ankle joint.
- application of the underliner and adjusting the fit in the manner described above results in proper alignment of the other components of the brace to provide a more comfortable and more correct fit.
- the amount of compression of the underliner can, likewise, be adjusted in this manner.
- the underliner of the present ankle support therefore provides a frontloading closure system, provides for a wide ° an ja of fit by having a tibia closure and a dorsal closure, and; also provides an adjustable compression from the brace, as we ⁇ H as serving to align the other components of the brace.
- a nylon stirrup member 30 that is affixed to the under ⁇ liner so as to extend along either side of the leg and around 5 the bottom of the foot in the fashion of a stirrup.
- Stirrup member 30 is preferably made of non-stretch nylon and is pre ⁇ ferably secured by sewing.
- Stirrup 30 is formed in an "L- shaped" configuration on either side of the ankle, to provide a means for attaching the other components so that they will not 0 stretch, whereby the brace, in which the various straps do not stretch, provides non-stretch support, not elastic support.
- An anchor strap 40 forms a loop going all the way around the brace and all the way around the leg above the an ⁇ kle.
- anchor strap 40 is 5 constructed so that some of the other components of the brace can be anchored to it.
- To apply anchor strap 40 its end is inserted through a buckle 36 and the strap is pulled tight and folded back on itself.
- a piece of vinyl 34 is provided to pro ⁇ tect the leg from the buckle 36.
- the outer surface of strap 40 - 0 is covered with a pile component 43 of a hook and pile closure device, and attached to the end of strap 40 is a piece of hook element 42. This piece of hook material 42 affixes to the pile 43 in order to secure anchor strap 40, and it creates an anchoring for stirrup 30.
- the anchor strap 40 By using the hook and pile closure system for the anchor strap 40, it becomes an adjustable means of pressure or an adjustable means of tightness for the brace, so that it can also accommodate a wide range of lower le sizes, yet it will still encircle the leg and attach to itself If the lower leg were very narrow, the hook component 42 coul continue around the leg and attach to any portion of pile com ponent 43.
- a piece of pile component 38 is secured on the stirru over the under-liner 20 below strap 40 so that first and secon lateral straps 50 and 60 can be affixed with a little mor security and with a little more bond to the brace.
- Both o these lateral straps (50 and 60) correlate to some of the liga ments of the ankle that are principally involved in an inver sion or a lateral ligament sprain of the ankle.
- the ligament that they correlate to are the anterior talofibular ligamen (strap 60) and the calcaneo fibular ligament (strap 50) , eithe or both of which might be stretched or partially or fully tor when an ankle sprain occurs.
- the lateral strap 50 which will also be referred to a the calcaneus strap, correlates to the calcaneus or the hee bone of the foot. Pulling this non-stretch strap - the fac that it is non-stretch is very important - affects th calcaneus bone in such a manner that it closes the ankle join (i.e., it effects the same mechanics on the joint that th ligaments will effect) , so the strap supports or replaces thos ligaments in the ankle.
- strap 50 is secured t stirrup member 30, preferably by sewing and it is secured a its top by means of a hook and pile closure system, of whic the hook component 52 is on the rear of the strap 50 a affixes to pile components 40 and 38 by simply being presse against them.
- Strap 50 there is a piece of pil component 53, to which strap 60 affixes by means of a ho component 62 on the rear of strap 60.
- Strap 60 is secured stirrup 30 at a point corresponding to the base of the fif metatarsal, to provide additional reinforcement to this lig ment group of the ankle.
- a medial strap 70 is secured to stirrup 30 below and in general lengthwise alignment with strap 50, in order to gain the effect of a continuous strap. Strap 70 is also secured to the stirrup 30 so that its secured end is in general alignment with the secured end of strap 60. Strap 70 balances out the force that straps 50 and 60 have on the heel and on the subta- lar joint, as well as on the positioning of the calcaneus of the heel bone. Adjusting the pulling relationship of the
- s ⁇ _raps 50 and 70 with respect to each other provides what is commonly called a "heel lock" in which the foot is cradled, and lateral movement of the ankle joint is limited, balanced and aligned.
- Strap 70 extends under the foot, upwardly along the inside surface of the foot and across the front of the ankle. As strap 70 is pulled upward, it provides an antipronational force, which prevents rolling-in of the foot, and it provides support to the arch which is very important in taping, strap- ping or supporting an ankle.
- straps 50 and 60 were pulled up too much and there were no support on the inside surface of the foot, the mechanism of the foot would be forced into a predisposition to pronate (rotation of the arch inwardly and down) , but strap 70 counterbalances this effect on the subtalar joint and creates a heel lock.
- Strap 70 continues across the outside surface of the leg and, by means of a hook element 72 of a hook and pile clos ⁇ ure, is secured to the pile surface 43 on strap 40. As a re ⁇ sult, it provides pressure on the hook and pile closures of straps 50 and 60, thereby holding those straps in place and keeping them from being torn off or loosened during use.
- a piece of pile component 45 is provided at the end of the anchor strap 40 at the end of the anchor strap 40 at the end of the anchor strap 40 at the end of the anchor strap 40 at the end of the anchor strap 40 at the end of the anchor strap 40 at the end of the anchor strap 40 at the end of the anchor strap 40 at the end of the anchor strap 40 at the end of the anchor strap 40 at the end of the anchor strap 40 .
- This provides a greater range of adjustment so as to accommodate a wide or narrow lower leg, a very thick or . fat ankle or bone structure or a combina ⁇ tion of bone and soft tissue.
- a piece of pile component 63 is provided at the top and at the outside of strap 60.
- the brace is provided in a left version and a righ version and, when applied, it is designed to resist latera ligament sprains or inversion of the ankle joint without affec ° ; ting plantarflexion or dorsiflexion of the ankle and/or t reduce instability to varus stress to the ankle. It provide support to the lateral ligaments of the ankle by means, of tw adjustable, non-stretchable straps which allow for comfort an adjustability of support, and it also provides a heel lock b 5 means of the medial strap which provides a balancing affect o the ankle joint and provides support for the arch.
- the under liner provides compression, warmth, and adjustability.
- the present ankle support or brace is primar ily designed to resist inversion sprains of the ankle, t reduce instability to varus stress and generally to provid warmth and compression to the ankle, it has been found usefu for medial sprains or sprains that involve the deltoid liga
