Field of the Invention This invention relates to orthopedic methods and devices, and more particularly to an improved orthopedic method and device for adjusting and maintaining shoes at a prescribed angle when used in the treatment of internal tibial torsion.
2. Description of the Prior Art In the past, corrective devices used in the treatment of internal tibial torsion have included rather heavy and complicated devices constructed of metal, and using metal screws, clamps, etc. for installation and adjustment. Some of these have been clamp-on devices which have projections that are destructive of bed sheets and furniture covers. Further, they exhibit some danger of causing injuries to persons wearing or adjusting them and, being generally rigid, they are not particularly comfortable. Still further, in some instances, the methods used in installation and adjustment of the devices involve considerable time and effort and with certain of them special purchased tools must be used to enable proper use of them.
SUMMARY OF THE INVENTION Accordingly, it is an object of this invention to provide an improved method and means for the treatment of internal tibial torsion wherein the aforesaid difficulties are eliminated.
These and other objects, features and advantages are accomplished in the present invention in which: first, the shoes of the patient are relatively positioned with heels together at a predetermined treatment angle; second, a strip of flexible material having one surface adapted to mechanically innerlock with a surface of a mating material is affixed to the outer sides of the shoes, extending from a position from the rear of the shoe forward a distance approximately in line with the tip of the blucher end of the shoe; third, a strip of coordinate mating material adapted to mechanically innerlock with the strips affixed to the shoes is'positioned in an engaging position over the affixed strips and thereby locks the shoes in position to the extent that they are thus unable to assume a smaller relative angle. In this manner, the patient is forced to maintain the feet in at least the angle determined by this method and means.

DESCRIPTION OF THE PREFERRED EMBODIMENT An orthopedic correction device 10 is fabricated from strips of mating or inter-engaging types of flexible material wherein one type material 12 has a surface 14 which includes a multiplicity of open-looped bristles and the other type 16 has a mating surface 18 which is provided with a crinkled nap. Two strips are thus interlocked or fastened when the inter-engaging surfaces are pressed together. Such fastening materials are commercially available under the trademark Velcro, and hereinafter the two types of material will be referred to as positive" and negative material, strip 12 being of negative material and strip 16 being of positive material. The strips of the material are of a width equal to approximately one-half the height of shoes 20 to which correction device 10 is applied. The method of practicing the invention is as follows:
First, the length of two strips 22 and 24 are determined by placing the end of one of the strips even with back seam 26 of shoe 28 or at the center of the shoe heel, and with the lower edge of strip 22 positioned along the top edge 30 of sole 32, strip 22 is extended toward the toe of the shoe. A mark is then made on strip 22 opposite blucher 33 of the shoe to indicate the correct length. Alternately, a length would be chosen which is approximately two-thirds the length of shoe 28. Strip 22 is then cut to the indicated length and the second strip, strip 24, cut to the same length. Forward extending ends 34 and 36 would then be rounded off as shown.
Next, using either strip 22 or 24 as a pattern, two identical dimensioned strips 38 and 40 are cut from Velcro positive material and are adapted to be attached to exposed surfaces 14 of strips 22 and 24 to cover the surfaces 14 for protection during normal wear periods, when treatment is not being effected.
Next, the smooth or non-engaging sides of strips 22 and 24 are glued to shoes 28 and 48, as shown, being in a position, as when measured, so that ends 44 and 46 of strips 22 and 24 are identically positioned in line with rear seams 26 and 47, respectively. The lower edges 49 and 50 of strips 22 and 24 are aligned with the top edge 30 of sole 32. A better bond between the strips and the shoes is achieved if outer region 52 of the shoe to be covered by strips 22 and 24, is lightly abraded before glue is applied.
The next step is to determine the length of interlocking strip 56. It is determined by using calibration chart 58, which is in the form of a protractor calibrated in positive and negative angular designations with the angle between like numerical designations corresponding to the angular displacement in degrees indicated by one of them. First, lines 60 and 62 are drawn from the point of origin 64 through positive and negative angular designations of the treatment angle. For purposes of illustration the treatment angle is assumed to be 40 degrees. Toe and heel index marks 68 and 70 are made on each shoe at points intersecting a center line fore and aft through the shoe and the right shoe 28 placed on line 62, and the left shoe 48 placed on line 60. The
heel and toe marks are aligned with lines 62 and 60, re-
aligning an edge 72 with edge 36 of strip 24 and pulling it tautly around the heels 74 and 76, extending it over strip 22 beyond end 34 of strip 22. A mark is then made on strip 56 at a point opposite the end of strip 22 and strip 56 removed and cut to a length indicated by this mark. This operation is, of course, performed with the shoes maintained at the prescribed angle.
Finally, the corners of the ends 72 and 78 of strip 56 are trimmed to provide circular end cuts as shown.
The corrections provided by this invention may be employed with various type shoes, particularly shoes prescribed by a physician. For example, a straight last shoe can be employed on one foot and a reverse last or club foot shoe used on the other foot. The reverse last shoe may be secured in any designated angular bias. In fact either shoe and last can be set at one degree of angular bias with respect to the leg, and the other set at another degree of angular bias. For example, the right shoe might be set at external rotation and the left shoe at 60 external rotation.
By means of the foregoing described method and construction there is provided a method and device for use in applying a prescribed angular bias between a pair of shoes, and thus to the feet of a patient wearing the shoes. Calibration, once achieved, as explained above, is maintained over extended periods of usage and treatment. There are no rigid arms extending between the shoes or protruding from the shoes and thus this invention provides a most comfortable as well as a reliable method and means of effecting a desired treatment.
What is claimed is:
l. The method of orthopedic adjustment for correction of internal tibial torsion comprising:
affixing to a pair of shoes of a patient an elongated base strip of flexible material having an outer surface adapted to mechanically engage a mechanically related surface, said base strip being affixed to an outer side of each shoes of said pair of shoes and being positioned generally parallel to the bottom of a shoe and extending from a point near the rear of the shoe forward;
positioning said shoes with heels together at a predetermined angle with respect to lines corresponding to fore and aft centerlines of the shoes;
an elongated outer locking strip, of a material having a surface adapted to engage and lock with said base strip on said shoe, is extended from the front edge of one of said base strips rearward around the heels of said shoes and in engagement with both said base locking strips to a point at least even with the front edge of the other base strip whereby said shoes are restrained from assuming a lesser angle than said predetermined angle; and
clipping off excess length from said outer strip whereby with the shoes at the prescribed angle the ends of said outer strip will be adjacent the front end of both said base strips, facilitating the repeated accurately locked positioning of the shoes.
2. The method as set forth in claim 1 wherein said strips are strips of Velcro interlocking material.
3. The method set forth in claim 1 wherein said base strips extend at least three-fourths distance from the rear of each shoe to the front of each shoe.
