DETAILED DESCRIPTION

[0024] A description of preferred embodiments of the invention follows. It will be understood that the particular embodiments of the invention are shown by way of illustration and not as limitations of the invention. At the outset, the invention is described in its broadest overall aspects, with a more detailed description following.

[0025] The inventor of the present subject matter has discovered a device and method for providing a means for improving the protection provided by currently available medical appendage-stabilizing devices and/or non-medical appendage-stabilizing devices. Non-limiting examples of a medical appendage-stabilizing device for use with an embodiment of the invention include an orthopaedic boot, sandal, hand or foot brace, a plaster hand or foot cast, semi-rigid, removable walking casts, and a hand or foot splint bandage. Non-limiting examples of a non-medical appendage-stabilizing device include a regular shoe, a sandal, a glove, and a sleeve.

[0026] The material used to construct the digit protector device can be chosen from any material having the ability to withstand a compressive force of a pre-determined magnitude. In a preferred embodiment, the digit protector device comprises a rigid or semi-rigid material. In one embodiment, the rigid or semi-rigid material is a metal, e.g., steel or aluminum. In another embodiment, the rigid or semi-rigid material material is polycarbonate or a plastic. Fluorinated ethylene propylene resin (FEP) is a highly inert plastic, and resistance to impact and tearing. Almost any FEP or FEP-encapsulated or coated elastomeric material is suitable for use in constructing the disclosed device.

[0027] In yet another embodiment, the disclosed device comprises an elastomer or an elastomeric material. An “elastomer” or an “elastomeric material,” as these terms are used and understood by those of skill in the relevant arts is any one of a various polymers having the elastic properties of natural rubber. The disclosed digit protector device may also be constructed of a resilient material. “Resilient,” as the term is used herein, refers to that property of a material that enables it to resume its original shape or position after being stretched, compressed, or bent. Elastomeric and resilient, as the terms are used herein, have similar meanings. The use of any type of rigid or non-rigid material for constructing at least a portion of the disclosed device is also possible. The disclosed device may be constructed of a completely rigid material.

[0028] Reference is now made to FIG. 1, which discloses one embodiment of the disclosed digit protector device 20 in the form of a substantially flat or contoured base member 21 configured for placement thereon of an appendage-stabilizing device, base member 21 having a top surface 22 and a bottom surface 24, an elongated proximal end portion 26 configured for attachment to the appendage-stabilizing device, and a distal end portion 28 having a curvature 30a forming a substantially upright wall portion 33a and a curvature 30b forming a substantially horizontal wall portion 33b, the wall portion 33a and the wall portion 33b defining a channel 32 configured to receive at least one digit protruding from the appendage-stabilizing device, the wall portions 33a and 33b forming a protective barrier over at least part of the channel 32, thereby providing protection for the at least one digit when the digit protector device is in use. Shown also in FIG. 1 are optional openings 36 formed in wall 33a, the openings 36 providing ventilation for the front part of the foot and the digits.

[0029] As the terms are used herein, “proximal end portion” is the portion of the disclosed digit protector device intended to be place nearer to the center of the body, for example the spinal column; and “distal end portion” is the portion of the disclosed device to be positioned farther from the center of the body.

[0030] In the embodiment depicted in FIG. 1, wall 33a and wall 33b are integral with base member 21. In other embodiments (not shown), wall 33a and wall 33b are formed separately from the same or different materials and bonded or otherwise fastened to one another, and wall 33a is bonded or fastened to base member 21.

[0031] FIG. 2 shows the disclosed digit protector device 20 being inserted in the direction shown by arrow 42 between the upper sole or lining 44 and the lower sole 46 of orthopaedic boot 40.

[0032] FIG. 3 shows the disclosed digit protector device 20 fully inserted 50 into the orthopaedic boot 40.

[0033] FIG. 4 shows a front portion of the disclosed digit protector device 20 fully inserted in orthopaedic boot 40 and in use on a patient and providing protection for toes 54 and foot.

[0034] In another embodiment the disclosed device 20 can be included in the preparation of a splint, brace or bandage 56, for example, as shown in FIG. 5. FIG. 5 shows the disclosed digit protector device 20 embedded in a bandage 56 or placed under a bandaged hand and providing protection for fingers 58, while preventing direct contact of a pre-selected portion of the hand with the protector device 20.

[0035] To more clearly depict some aspects of the protection provided by the disclosed device. FIG. 6A is a side elevational cut-away view 60 of a digit protector device 20 according to an embodiment of the invention embedded in a sole of an open-front shoe or boot. FIG. 6A is not drawn to scale. FIG. 6A shows the device 20 “sandwiched” between the lining or inner sole 44 of an orthopaedic shoe or boot and the outer sole 46 of the boot. It is important that the device 20 is anchored or secured under the inner sole or lining 44 such that an impact to the front vertical portion 33a of the insert device 20 does not push the insert device 20 against the toe or finger. In most applications, the elongated proximal end portion 26 of the insert device 20 should be pressed or butted against the inside back of the shoe or the boot. The posterior portion of lining 44 may be an elastomeric or “rubber” type material, such as found in a BAUERFEIND® GLOBOPED™ (Bauerfeind AG, Zeulenroda, Germany) Heel Relief Shoe or boot.

[0036] The elastomeric “posterior “lip” of the GLOBOPED orthopaedic boot helps to prevent or to heal heel sores in patients. Such sores can become seriously infected and lead to general sepsis and death. The disclosed insert device 20 works as an insert with this type of boot to allow the elastomeric posterior lip of the orthopaedic boot to function as designed, while the insert device 20 protects the front part of the foot and toes 54 of the patient. In a type of boot having an open heel portion as well as the open front, it is especially important that insert device 20 be secured in place or anchored down. Space 62 provides for circulation of air to promote healing.

[0037] FIG. 6B is a partial schematic of a side elevational cut-away view 66 of a digit protector device 20 according to an embodiment of the invention embedded in a sole of an open-front shoe or boot. In order to alleviate pressure on the heel, a particular boot may have a gel cushion or an elastomeric material in the boot positioned to be under the heel of the wearer. Other non-limiting examples of orthopaedic shoes or boots that may be modified for use with the disclosed insert may be available from DARCO® by ALIMED® (Dedham, Mass.).

[0038] FIG. 6B also shows a surgical pin 80 inserted in a toe 54 of the patient. In any embodiment of the invention, sufficient space 62 can be provided to accommodate a surgical pin protruding from a toe or a finger. Optional openings 36 (shown in FIGS. 1, 3, 4, 5, and 6C) provided in the substantially upright wall portion 33a of the protector device 20 allow easy access to a surgeon or other medical practitioner for removing the surgical pin without having to remove the protector device 20.

[0039] FIG. 6C depicts an embodiment of the insert device 20 having a forward distal end portion having a curvature portion 33a that extends upwards but has no horizontal wall portion 33b as in FIG. 1. FIG. 6C also depicts an hour-glass shaped elongated proximal end for ease of insertion in a shoe or boot. The elongated proximal end can be any shape suitable for insertion in a particular appendage-stabilizing device, and the size can be varied according to the wearer.

[0040] In another embodiment, the edges of the elongated proximal end portion 26 of the digit protector device 20 may be serrated or asymmetrically shaped so as to provide better anchoring of the digit protector device in the cast, brace, splint, bandage, or boot.

[0041] In yet another embodiment the digit protector device 20 can be fitted with labels or decoration to personalize or to identify the owner or to represent or display a special interest of the owner.
