6 Claims. (Cl. 128-80) I The present invention relates to improvements in orthopedic devices and particularly to such devices used in the treatment of congenital and acquired deformities in childrens legs or feet, such as for example, clubfeet, foot abduction, foot adduction, knock knees, and bow legs.

In treating abnormal foot and leg conditions, responsive correction may be achieved by rotating the deformed limb or limbs about one or more axes and maintaining the limb in a predetermined position. The degree and combination of attitudes required to effect proper orthopedic treatment varies considerably with the individual. Preferably, therefore, orthopedic devices should have a wide range of adjustment and adaptability.

Conventional devices now in use are specially made to meet the requirements of individual patients requiring close cooperation between the orthopedic surgeon and a splint marker. Such conventional devices, in addition, have only a limited range of adjustment and adaptability requiring progressive changes in the splint or orthopedic device as the improvement in the affected limb results in a need for less and less displacement of the limb. Further, such devices are awkward and cumbersome, restricting the activity of the child, and when in use tend ,todamage sheets, blankets, furniture, etc., with which the device comes in contact. Finally, such devices, are formed with the childs shoe as an integral part thereof, complicating the problem of'replacement as the size of thechilds foot increases with age.

- Accordingly, it is an object of this invention to provide an orthopedic device or splint suitable for correcting a wide variety of abnormal foot and leg conditions which will overcome the above disadvantages.

It is a further object of this invention to provide anort hopedic splint which is sufliciently adjustable and adaptable to permit the device to be substantially uni- United States PatentO 2,920,620 Patented Jan. 12, 19 60 Fig'. 2' is a side elevation of the device partially in phantom.

Fig. 6 is ,a partial sectional view taken substantially along the line 6--6 of Fig. 1.

Referring now to the drawings, the orthopedic device indicated generally at 10 includes apair of plate members or shoe holding platforms 12 and 14 and a spacing bar 16. The plate members 12 and 14 are identical in form and as shown in the drawings are preferably sectorially shaped, each having a rounded apex end 18 and an arcuate opposite end 20. Each plate member is provided with a pair of guide channels 22 and 24 transversing the plate member or platform obliquely between the apex end '18 and the arcuate opposite end 20. The channels 22 and 24 intersect one another at approximately midpoint 26 of the platform. This construction permits the platform to be positioned on the bar 16 in two attitudes displaced at approximately 60? to one another. This is illustrated by the relative positions of the plate member 14 in Figures 1 and 4.

Each platform is provided with means for attaching a childs shoe in various angular positions. these means include an opening 28 at the apex end 18 and a plurality of openings 30 uniformly displaced along the arcuate end 20.

- A childs shoe 32 adapted to be attached to either of 5. This shoe is provided with a threaded heel opening 34 adapted to match with the opening 28 and a pair of versal and rapidly applied to a wide variety of patients.

Still another object of this invention is to provide a construction by which shoes may be mounted upon the orthopedic splint in a positive but simple manner, permitting easy removal at a later time.

Still another object of this invention is to provide such an orthopedic device which is of simple and prac.

tical construction having a plurality of interchangeable; parts thereby considerably reducing manufacturing costs.

and retail distribution problems.

A more particular object of this invention is to provide such a device having no rough or sharp edges or projections, reducing the probability of damage to sheets, bedding and furniture to a'minimum.

Other objects and advantages of this invention will be apparent, it is believed, to those skilled in the art from the following detailed description of a preferred embodiment thereof when taken in connection with the accompanying drawings in which Fig. 1 is a top plan view partially in section of the orthopedic device.

threaded toe openings 36 adapted to match with adjacent openings 30 of the arcuate end 20.

By this construction it will be apparent that the shoe 32 can be positioned on either platform 12 or 14 in a plurality of angularly disposed positions by securing the shoe to the platform with suitable bolts 38 adapted to be received within the respective threaded openings.

- As shown in Figure 6 the bottom of the shoe 32 is provided with suitable threaded sleeves 40 to receive the bolts 38 while the bottom 42 of the platform is provided with suitable recesses 44 at one extremity of the opening 28 to receive the head of the bolts 38.

The spacing bar 16 is adjustably received within one of the channels 22 or 24 of each platform 12 and 14-. The bar 16 is provided with a plurality of threaded openings 46 at either end thereof by means of which the platforms may be adjustably positioned along the length of the bar.

The lower side of each platform is provided with a recessed opening 48 at approximately the mid-point 26 thereof. The opening 48 is adapted to receive a bolt 50 which threadedly engages one of the openings 46 of the bar 16. By this construction the linear distance between the platforms 12 and 14 can be carefully an accurately controlled.

The platforms 12 and 14 may be formed of any suitable material. I prefer, however, to form them of synthetic resins or plastic materials for ease of manufacture and to permit use of materials which, while being strong, will not tend to damage furniture, rugs, or other material with which the device comes in contact.

The spacing bar 16 is preferably formed of metal so that it may rigidly hold the platforms in a predetermined spaced relationship.

Preferably- In many cases it is desirable to have both platforms and thus both shoes lying within a single plane. However, in correcting leg as distinguished from foot deformities it is sometimes desirable, as shown in Figure 3, to distort the bar 16 in order to force the legs in or out. The bar is thus bendable to tilt the plate members relative to one another.

In the use of the device thus described, an orthopedic surgeon, having examined a patient and decided on a course of treatment, determines the relative amount of longitudinal rotation of the foot about the normal axis desirable for the corrective measure. The platforms 12 and 14 are then positioned upon the bar 16 by inserting the ends of the bar in one or the other of the channels 22 or 24. The opening 48 is positioned adjacent one of the openings 46 determined by the desirable spaced relationship of the platforms. The platform is then secured to the bar by the bolt 50. By suitably positioning the platforms on the bar the physician may secure shoes thereto by the manner previously described in toe-in toe-in relationship, toe-out toe-out relationship, toe-out toe-in relationship, or any degree therebetween.

Finally, in correcting bow legs or knock knees the physician may bend the bar 16 to any desired degree dictated by the prescribed treatment. The child, in wearing this device, has his feet securely held by the shoes 32 so that they are in a substantially permanent angularly displaced relationship, hastening the correction of the deformity.

Since all surface parts of the platforms are smooth and the holding bolts recessed, there is little likelihood that damage to household furnishings with which the child comes in contact will occur.

Further, since the bottom of the platforms are fiat, the child is permitted to stand and may even walk.

It will be apparent from the above description of a preferred embodiment of this invention that the particular size of the platforms and length of the bar will be dictated by the size and strength of the patient to be treated. In addition, as the child grows in size, larger shoes may be readily adapted to the same orthopedic device, eliminating the expense of subsequent splint making. Further, as treatment decreases the extent of the deformity, the relative angular displacement of the platforms, shoes or bar may be changed readily and conveniently at home to adjust the splint to the childs changing orthopedic needs.

Finally, it will be apparent that a wide variety of materials and fabrication techniques may be used to construct the present device thereby permitting, in particular cases, the device to be adapted to the individual needs of particular patients.

Having fully described my invention, it is to be understood that I do not wish to be limited to the details set forth, by my invention is of the full scope of the appended claims.
