Turning in of the feet or clubfeet is a problem that commonly occurs in infants and young children. The deformity occurs as a result of metatarsus varsus, also known as metatarsus adductus, caused by the forefoot being in an adducted position in relation to the hindfoot. This is usually accompanied by internal tibial torsion or bowing of the Shinbone which adds to the toeing-in appearance. If this condition is not corrected in an early stage, the abnormal condition may result later in pigeon-toeing" or clubfoot and/or bow legs.

In the past, various forms of treatment have been employed. These have included the use of bars to which the feet were secured and bound by strips of adhesive tape to maintain the feet in a turned-out position. This required frequent, laborious and uncomfortable changing of the tape and numerous time-consuming and expensive visits with the doctor to achieve the gradual outward rotation of the feet. The treatment has been often poorly tolerated by the young patients who experience conditions of abrasion, erosion and/or ulceration of the skin to which the confining bindings are applied.

Attempts at modifying the aforementioned procedure and making it less onerous and less psychologically fearsome and impressionable upon the infant have consisted of the use of shoe-like enclosures or complex holding devices fixed to a bar with an adjustment required to gradually reposition the outward angle of the foot enclosure or the widening of the angle of the bar itself. Although these methods have been effective, they have the attendant disadvantage of requiring periodic adjustment of the angulation and the difficulty in daily forcing the turned-in feet into the rigidly outturned foot enclosure. The awkwardness and the weight of the device and the occasional blistering and- /or contusion of the skin at the instep and behind the heels of the foot, caused by the foot enclosures and the relatively great expense of the treatment, have militated against theirousage in many instances.

Examples of prior art disclosures requiring frequent adjustment and the use of foot enclosure devices may be found in the prior art patents of Dalpe U.S. Pat. No. 1,124,596, Bosler U.S. Pat. No. 2,545,410, Gessel U.S. Pat. No. 2,702,542 and Freeman U.S. Pat. No. 2,815,021.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an unusually simple, inexpensive splint that may be used to correct the aforementioned foot condition.

Another object of the invention is to provide a corrective splint that may be used on the afflicted child by his parents or others without the requirement of medical technology and/or medical skills.

It has been found that prior art devices have utilized cumbersome boots and other enclosures that tend to frighten and leave an ugly everlasting psychological impression upon the mind of the child. Accordingly, another feature and object of the invention resides in the simple unitary details of openwork construction that is unencumbered by frightening shoe-type enclosures and that are thereby more psychologically acceptable and tolerated by the child without the resultant production of contusions, abrasions and irritations to the tender skin.

The above description, as well as further objects, features and advantages of the present invention, will be more fully appreciated by reference to the following detailed description of a presently preferred, but nonetheless illustrative, embodiment in accordance with the present invention, when taken in conjunction with the accompanying drawing, wherein:

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view taken at a angle of the front and top of a corrective foot splint constructed according to the invention;

FIG. 2 is a top view; and

FIG. 3 is a front view.

Referring now to the drawing, the corrective foot splint is generally identified by the numeral 10. It comprises a unitary base 12 defining two separate but

integral foot supports

14 and 16. Intermediate the foot supports 14 and 16 is a heel support portion 18 that functions as a unitary connection between the two supports 14 and 16 to maintain the both foot supports immovably related to each other at a diverging included angle of approximately 60.

The heel support 18 is raised slightly higher than and above the foot supports 14 and 16, as may be seen more clearly in FIGS. 1 and 3, to provide two heel

sup port surfaces

20 and 22, one for each of the respective foot supports 14 and 16. The

heel support surfaces

20 and 22 are contoured smoothly to provide a raised and curved surface against which the heel of the foot, resting upon one of the respective foot supports 14 and 16, may be positioned and retained. The heel supports 20 and 22 are in alignment with their respective

foot support surfaces

14 and 16 so that the deepest portion of such heel supports is centered along the central line of such respective foot support. Although not shown in the drawing, each contoured

heel support surface

20 and 22 may be provided with a layer of soft material such as felt, foam rubber or the like to provide a warm, soft feeling to the foot when the heel is placed thereagainst.

Each

foot support surface

14 and 16 is substantially planar and uninterrupted and, therefore, substantially free of any obstruction. This open appearance is important to prevent the occurrence of abrasions, contusions and other forms of irritation to the tender skin of the foot resting thereon. Once again, although it is not shown in the drawing, it is within the contemplation of the invention that the

planar surfaces

14 and 16 may be coated or provided with layers of soft, absorbent materials such as foam rubber, felt and the like against which the foot may rest when supported on such surfaces.

Illustrated in the drawing for exemplary purposes only are releasable fastening means in the form of straps 24 which may be adapted to pass through appropriate slots 26 or other holding and positioning means in the base of each

foot support surface

14 and 16. Each strap may be provided with a releasable fastening element such as a buckle, snaps, clips and the like. In the present disclosure, and for the convenience of understanding, the straps are provided with interengaging loops and books, more commonly known in the art by the trademark Velcro. The velcro fastening structures are placed at the opposite ends of the straps such as is illustrated at 28. In practice, it has been found that the Velcro fasteners permit adjustment of the straps without the need for cumbersome buckles and adjustment holes, although such buckles and hole combinations may be employed with equal facility in the present invention.

In operation, the feet of the child are placed against each of the respective

foot support surfaces

14 and 16 with the heel of each respective foot positioned rearmost on their respective surfaces and in the deepest portion of the conformingly shaped

heel support surfaces

20 and 22. Because of the raised height of the connection 18 and as a consequence of each of the conforming

heel support surfaces

20 and 22, the heel of each foot is adequately supported at the connection and, thus, prevented from being lifted free by the child and removed therefrom after the foot is strapped or retained to the respective

foot support surface

14 or 16.

Accordingly, after the foot is positioned against the heel of its respective

foot supporting surface

14 or 16, the releasable securing strap means 24 is then positioned about the instep and adjacent portions of the upper surface of the foot, thereby encompassing the foot and retaining it substantially flat against the

foot supporting surface

14 or 16. The width-wise extent of the releasable fastening means 24 may be varied. However, in practice, it has been found that by making the width of the releasable fastening means 24 of sufficient extent, the same will cover a substantial lengthwise portion of the instep of the foot to thereby prevent the foot from being removed from its

foot support surface

14 or 16. The initial positioning of the heel of the foot in the deepest portion of the contoured

heel support surface

20 and 22, the height of the conforming heel supports and the extent of encompassment of the strap 24 prevent the child from being able to lift his foot free of the splint without first releasing the strap.

A unique feature of the invention resides in the simplicity of structure of the splint in that both foot supports are formed as a single and unitary uninterrupted base 12, the details of which are incapable of relative movement with respect to each other. The connecting portion 18, although shown formed as a unitary part of the base 12 and its two non-movable foot supports 14 and 16, may be provided as a separate element but subsequently made integral with such base. The height of the heel support surfaces and 22 may be controlled to provide sufiicient support to the heel of the foot and when so controlled, will prevent the dislodgment and disengagement of the foot from the conforming heel support surface, even in the event the strap or releasable fastening means 24 is not tightly engaged about the instep of the foot.

It is to be recognized that the open appearance of the splint 10 avoids creating an everlasting frightening psychological impression upon the mind of the child to which the same is applied and, therefore, makes the same more readily usable and more palatable for use by the child. The unitary details of structure and the openness of such structure also avoid the possibility of damage to the tender skin and surfaces of the childs foot while enabling the same to be applied to the feet byany non-skilled individual without the requirementof prior medical knowledge and techniques.

While there have been shown and described and pointed out the fundamental novel features of the invention as applied to a preferred embodiment thereof, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
