United States Patent 3,477,426 CLUBFOOT SPLINT Joseph J. Wincheski, 1606 Gridley Lane, Silver Spring, Md. 20902 Filed Nov. 30, 1966, Ser. No. 597,926 Int. Cl. A61f /00; A6311 21/02 US. Cl. 12880 18 Claims ABSTRACT OF THE DISCLOSURE A clubfoot splint including two plate mounting members adapted to be fixed to the shoes of a user, and a pair of tightly wound coil springs interconnecting the mounting members to normally hold them in laterally spaced coplanar position against movement in the same plane while permitting relative movement of the mounting members about an axis transverse to the coil springs to allow the user to move his feet vertically relative to each other thereby providing flexibility in the ankles and knees.
The present invention generally relates to orthopedic correctional devices and more particularly to a new and improved clubfoot splint which may be applied to a patient at rest such as during the night for correcting and holding clubfeet in a predetermined position. One particu lar application of the present invention is for correcting inturned and outturned feet although the present invention has other analogous uses.
With conventional or prior clubfoot splints, the clubfeet are held in the desired corrective position however little if any flexibility is allowed for the patient to move his knees or ankles. This condition not only presents appreciable discomfort but moreover may cause or aid in the development of pronated flat feet.
Accordingly it is an object of the present invention to provide a new and improved clubfoot splint which will hold clubfeet in the desired corrective position but will allow the patient flexibility particularly in the ankles and knees to thus overcome the aforementioned problem.
A further object of the present invention is to provide a clubfoot splint which will achieve the above advantages and yet may be economically manufactured and made available at relatively low retail price and which moreover may be easily adapted for connection to the shoes or feet of a patient.
Other objects and advantages of the present invention will become apparent from the following detailed description and the accompanying drawings, in which:
FIGURE 1 is a plan view of a clubfoot splint embodying the present invention;
FIGURE 2 is a front elevational view of the splint in FIGURE 1 and additionally showing in phantom a pair of attached shoes;
FIGURE 3 is a cross-sectional view taken generally along lines 3-3 of FIGURE 1; and
FIGURE 4 is a fragmental cross-sectional view taken generally along lines 4-4 of FIGURE 3.
Referring to the drawings in detail there is shown for illustrative purposes only, an orthopedic splint embodying the present invention, for use in correcting clubfeet, FIGURE 2 showing the splint 10 attached to a pair of shoes 12, 14.
In the shown embodiment the splint includes a pair of mounting members formed by elongated plates 16, 18 which may be made from sheet aluminum 0.063 gauge. Plates 16, 18 which may be respectively attached by suitable fasteners to the shoes, the plates being provided with apertures 20 in their opposite ends for this purpose. The
mounting plates are oriented at the desired corrective angle, shown as about 45 degrees, with respect to each "ice other so that when applied as a unit to clubfeet, as will be described, they will extend at the same angle.
In accordance with the present invention mounting plates 16, 18 are interconnected and held in the desired angular relationship by resilient means which in the preferred embodiments are formed by a pair of coil springs 30 and 32. While the illustrated springs are provided by .090 inch (diameter) tightly wound spring piano wire, other resilient members having a force in the range of 300,000 to 400,000 pounds per square inch may also be employed.
Thus attached, springs 30, 32 extend parallel to each other and preferably with a spacing of 2% inches. In this manner they serve to interconnect mounting plates 16, 18 in coplanar relationship while maintaining the de sired corrective angle between the plates, the latter being obtained by the nature of the springs which are virtually incompressible and therefore prevent shifting of the plates in their normal plane. However springs 30, 32 are resiliently flexible about an axis transverse thereto such as for example an axis bisecting the angle between the plates. This flexibility allows the mounting plates to be shifted out of coplanar relationship into different levels to allow the patient to flex his ankle or his knees or other parts of the legs and feet. This is illustrated in phantom in FIG- URE 2 wherein one shoe is raised relative to the other, the springs flexing upwardly to permit such movement. When unstressed, the springs will hold the mounting plates in coplanar relationship as shown in FIGURE 1.
Although not shown it will be readily apparent that the mounting plates 16, 18 may be adapted for adjustable connection to shoes so as to permit the corrective angle to be varied depending upon the particular deformity in the patient. Additionally suitable means may be provided for direct attachment to the feet or for clamping attachment to the shoes. The resilient feature of the present invention may be incorporated into a plaster of Paris foot mold if desired.
Other modifications of the present invention readily apparent from the foregoing description and accompanying drawings although not specifically described or shown in the drawings will nevertheless be included in the scope of the invention as indicated in the appended claims.
