normalmanner while exerting corrective pressure upon the deformed feet.

With this general object in view and such others as may hereinafter appear, the invention consists in. the orthopedic corrective apparatus hereinafter described and particularly defined in the claimsat the end of this specification.

Inthe drawings illustrating the preferred embodiment of the invention, Fig. 1 is a perspective view of an orthopedic corrective apparatus embodying the invention; Fig. 2 is a plan view of the same, as seen from the underside, and Fig. 3 is a cross-sectional detail view taken on the line 3-3 of Fig. 2.

In general, the present invention contemplates an orthopedic corrective apparatusparticularly adapted for the correction ofa club foot condition and which is designed to be secured to the shoes of the patient and adjusted to a position to exert corrective pressure on the aiilicted foot or feet to an extent determined bythe orthopedic surgeon, to thereby effect the muscular corrections. 7 Prior to the present invention it has been the usual corrective practice for club foot condi tions to have the child wear a splint structure comprising a relatively narrow fiat elongated bar adjustably secured at its'ends to the sole of each shoe adjacent the heel, the adjustments being madeat each end tohold the feet atfthe desired positions. This prior structur has been found unsatisfactory for the reason that, it does not permit the patient to move or kick his legs and feet while lying in bed and since the adjusting 'elements project from the underside of the shoes, the splint must be removed when the child starts to walk. l

In accordance with the'present invention, the foot corrective apparatus is designed to enable the appliance to be worn continuously by the child with minimum. interference withnormal actionsQpermitting the, child to kick and move its legs and feet without handicapping muscular coordination. The apparatus also permits the child to stand and also to ambulate while the correction of the deformity is being accomplished.

In practice, the apparatus mayjand'preferablywill be used we ma hes were are;

9 Claims. (Cl. 128-80) 2 cially designed to hold the foot in an outwardly turned position, the forward portion of the shoes having a distinct outward flare.

.- Referring now to the drawings, the orthopedic corrective apparatus herein illustrated comprises in general a pair of base or supporting members I0, I 2-for the right and left feet respectively and to which the shoes I4, I 6 of the child may be attached. Each base member l0, I2 is provided with a hinged structure, indicated generally at I 8, 20, the hinge pins 22 being disposed substantially parallel to the inner edge of each shoe and a short distance above the base members. The two hinged structures are connected by a brace unit, indicated generally at 24, arranged to be adjusted to maintain the feet at the desired angle and to permit lateral rocking and reciprocation of the feet relative to one another while maintaining the feet in a predetermined outwardly spread angular position. The shoes [4, l6 used with the apparatus may and preferably will comprise commercially available corrective shoes particularly adapted for the correction of club feet,

the illustrated shoes havin an outward flare at each shoe may be detachably secured to its base members l0, I2 in any convenient manner, herein shown as by a clamp including a heel plate 25 attached to the base and turned upwardly and inwardly to embrace the heel end of the shoe sole between the sole and the upper, and a transversely extended clamp secured to the forepart of the base having a stationary clamp portion 21 arranged to embrace one side of the shoe sole and an adjustable clamp portion 29 arranged to embrace the other side of the shoe sole, the clamp portion 29fbeing locked in its adjusted position bya bolt 3|. The heel plate 25 and the clamp member may be fitted into recesses formed in the upper surface of the base members and may be attached by flush rivets, as illustrated.

Each hinged structure I8, 20 is similar in cons tru'ction and operation and as herein shown, comprises a pair of transversely extended and spaced strap members 28, 30 attached to the upper surface oftheir base members, the straps being disposed substantially at the toe and heel ends of the base. The inner ends of the straps are extended a short distance beyond the inner edge of the base and are provided with upwardly bent, portions 32, 34 forming supports at their upper ends for the hinge pin 22 secured to and extended therebetween. A's herein shown, the strap members 28, 30may. be secured to the upl per surface of the base member by rivets Sit-or the like, the base member being preferably recessed, as indicated in Fig. 3, on its upper side to receive the strap members and to dispose the top of the straps flush with the top of the base member, thus providing a flat upper surface to which the sole of the shoe may be detachably connected as described, and also providing a fiat bottom surface for the base members to permit the child to stand and, walk with minimum impedance by the corrective apparatus.

The brace unit 26, as herein illustrated, comprises two brace rods 38, 40 each rod having a straight portion 42 arranged substantially paral-'- lel to and hingedly and slidably connected to its respective hinge pin 22. Each rod is further pro-,- vided with upwardly and inwardly bent portions M, 45 connected at thei inner ends by bolts 4'! of the supporting members while maintainin the same in said predetermined angular position.

2. Orthopedic corrective apparatus comprising apair of supporting members attachable to the patients shoes, brace means connected to and extending between said supporting members for and nuts 49, to an intervening tie piece 48. The straight portions 42 are hingedly and slidably connected to the hinge structures I8, by a pair of spaced links 50, 52 secured to the straight portions as by pins 53 and rockingly and slidably mounted on the hinge or slide pin 22. Angular adjustment of thebrace unit may be effected at either or both of the points of connection to the intervening tie piece 48 by loosening the bolts and swinging the rods 38, 4% to the desired angle and thereafter again tightening the connections. It will be observed that the entire operating structure is disposed above the base members Hi, [2 so that there is no obstruction to impede the child from standing on the floor or walking while wearing the apparatus.

From the above description it will be seen that in operation, the apparatus can be adjusted angularly to the desired position as determined by the doctor, and that the slidably hinged structure permits laterial rocking and relative longitudinal movement of the feet and legs while maintaining the 'feet in the desired position of correction. In practice, when the child kicks its legs in opposed directions the hinge pins 22 will slide in the links 50, 52 until one link, 52, of the rod tBengages the end of the rear support Stand the link 5|) of the opposite rod engages the for ward support 32 the operation being reversed when kicking in the opposite direction. In a similar manner, when walking, the feet may be al- 'ternately lifted and extended forwardly within the limits of the hinge rod supports 32, 34 while maintaining the feet in the corrective position, the pivotal arrangement permitting the wearer to lift one foot relative to the other while wearing the apparatus.

The feature of detachably connecting the childs shoes to the base members l0, IZ'is of distinct advantage in permitting the device to be. easily removed and replaced when desired. How

ever, it will be understood that the shoes may be permanently attached to the base members, if desired, in any convenient manner, such as by riveting the soles of the shoes to the base members.

Although the invention has been herein illustrated and described as primarily designed for correction of a club foot or talipes condition, or

for a pigeon-teed or metatarsus varus deformity,

3. Orthopedic corrective apparatus comprising a pair of supporting members attachable to the patients shoes, brace means connected to and extending between said supporting members for maintaining the supporting members in a spaced and predetermined angular'position relative to each other, and connectin means between the brace and the supporting members for permitting lateral rocking and relative longitudinal movement of the supporting members While maintaining the same in said predetermined angular position, said brace means and said connecting means being disposed above the bottom of said supporting members to permit the patient to stand and walk, while wearing the apparatus.
