Sheet 2 of2 INVENTOR HOWARD L. PHELPS BY ifg w ATTORNEYS BACKGROUND OF THE INVENTION I. Field of the Invention The invention concerns itself with the correction of the deformity in an infant, at birth, in regard to an abnormal position and shape of the foot, known as clubfoot. One of three manifestations of this deformity is a so-called plantar flexion of the foot at the ankle, so that the foot points downward; and this condition is the one which the improved splint of the invention is primarily designed to correct. However, the other manifestation of deformity, i.e., an inversion of the foot, or rolling in of the sole so that the soles of the feet face each other, and an adduction of the forefoot, or pigeon-toe deformity, may well also yield to treatment by the improved device.
2. Description of the Prior Art The Dennis Brown splint represents, to my knowledge, the state of the art at present, being in the form of a rigid crossbar to which the infants shoes are rigidly clamped in outwardly divergent relation to one another. However, as indicated above, the objective of such a splint is in considerable measure combatted and frustrated by the infants urge to point his toes, thereby denying exercise to the heel cord such as is, in my opinion (confirmed by professional opinion), necessary to correctively treat the clubfoot.
SUMMARY OF THE INVENTION As indicated above, the device of the invention is, in summary, represented in its most preferred embodiment by a generally cross-shaped structure, a crossbar part of which is rigidly, though adjustably, bolt-secured at its ends to the infants shoes, approximately at the instep zone thereof. In regard to the basic improvement, a stem of the device is in the form of a tongue-like prop disposed at 90 to the crossbar and adjustably clamped on a bracket fixed at the center of the latter, and, when the infant is prostrate on its back, the prop inclines downwardly at a mild angle of, say, from coplanar relation to the crossbar. Thus, with the shoe heel and forward tip ofthe prop resting upon a floor or like support surface, the sole of the shoe is positively forced backwards, tensing the heel cord in a manner which the infant instinctively resists by trying to point its toes forward. This, as intended, simulates a heel and toe walking action, forcing the alternate tensioning and relaxation of the heel cord, with corrective results. Accordingly, the need for surgery to correct the clubfoot, attended by danger in the use of anesthetics, is avoided or, in the event surgery is performed, post-operative recovery is assisted.
Should the infant roll over onto its stomach, a refinement on the basic improvement contemplates the provision of a second prop disposed oppositely of the first, so as to force a similar exercising action in this posture.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view ofa device incorporating the essential invention, as applied to a pair of infants shoes;
FIG. 2 is a top plan view of the device, the general position of the shoes being indicated in dot-dash line;
FIGS. 3 and 4 are views in transverse vertical section along line 3--3 and 4--4, respectively, of FIG. 2; and with the prop and crossbar of the device in a coplanar relation to one another;
FIG. 5 is a fragmentary view showing provision for the adjustable clamping of one end of the crossbar ofthe device to a shoe;
FIG. 6 is a view similar to FIG. 2, showing a refined embodiment including a second tongue or prop to cope with the situation in which the infant turns face downward;
FIG. 7 is a fragmentary section on line 7--7 of FIG. 6; and
FIG. 8 is a view similar to FIG. 5, showing the optional use of an adapter clog to assist the infant in standing when the device of the invention is removed.
DESCRIPTION OF PREFERRED EMBODIMENTS The splint adapter of the invention, generally designated by the reference numeral 10, is shown as being comprised of a rigid, transversely elongated crossbar 12 which is equipped at its ends with like clamping units 14, by which it is rigidly secured to an infants shoes in the instep zone of the latter, with the shoes pointing divergently outwardly. In the manner of the Dennis Brown splint, each unit 14 comprises, as shown in FIG. 5, a threaded stud I5 projecting through the sole of the shoe and through an opening at the end of bar I2, with a washer I6, hex nut 17 and knurled lock nut 18 applied to stem 15 in that order outwardly of bar 12. The shoe sole is calibrated at 19 (FIG. 5) to indicate a rough angle of adjustment of the shoe relative to crossbar 12, which angle is pre-set and maintained when nuts 17 and 18 are taken up tightly on the stud 15.
A bracket 21 is provided, including an U-shaped mounting element 22, which mates over crossbar 12 at the center point of the latter, being rigidly secured thereon by a pair of lock nuts 23 threaded into one of the legs of element 22 to bear against the bar; and, integrally connected with clamp bracket 22, there is a forwardly projecting pivot element 25 having a slotted tongue at 26, within which a forwardly projecting, tongue-like prop 28 of the device 10 is pivotally mounted.
To this end, a plastic body 29 of prop 28 has a pivoting plate 30 inset into the rear end thereof, and locked up to body 29 by screws 31; and plate 30, projecting rearwardly of the body has an apertured pivot portion 32 transversely aligned with apertures in the pivot portions 26 of the element 25 of mounting bracket 21. The aligned apertures receive a knurled screw 34, with washers 35 applied to the latter externally of element 25 and a nut 36 threadedly applied to screw 34.
Accordingly, loosening of the screw 34 permits a desired angular adjustment of the tongue-like prop 28 downwardly from a coplanar relationship with the crossbar 12, which permits the application of the desired rearward force on the shoes S at the crossbar l2 and connecting bracket 21. In a typical application, the angularity of prop 29 will be, say, 17, or in a general range of 15 20. The effect is illustrated in FIG. 3. Of course, if desired, the prop 29 and crossbar may be coplanar as suggested in FIG. 4; however, the invention primarily contemplates the exertion of mechanical opposition I to the natural tendency of the infant to stretch its toes forwardly which, if unopposed, deprives the heel cord of repeated tensional exercise, as contemplated under the principle of the invention.
It is entirely possible that the infant may successfully thwart the purpose ofthe embodiment of FIGS. I -5 by the simple expedient, once strength is attained, of rolling onto its stomach. Accordingly, the basic structure is further refined by provisions shown in FIGS. 6, 7 and 8 to impose, in this face downward posture, a restraint similar to that in effect when the child is on its back. To this end, a second tongue-like prop facing oppositely of prop 28 is provided and, since most of the v structural refinements of the device of FIGS. 6- 8, which is generally designated 38, duplicate those of the basic device 10, they are designated by corresponding reference numerals, primed; and further detailed description thereof is dispensed with.
The device 38 has its crossbar--engaging mounting bracket, specially designated 39, altered to provide a second slotted tongue 26 facing oppositely of the tongue 26 at to the length of crossbar 12; and a second pivoting plate 32' is received within the furcation of tongue 26, being locked in an adjusted position therein by screw and nut means 34. 36.The second prop 28' substantially duplicates the first, save for being inclined from crossbar I2 in the opposite vertical sense, although at about the same mild angularity, as appears in FIG. 7.
The child having rolled (or been placed) face-downward finds its effort to point its toes clockwise (FIG. 7) to be resisted by the prop 28", and in repeating the effort produces the desired beneficial exercising of the heel cord.
FIGS. 6- 8 also show an optional provision of a relatively thick toe clog 40 on each shoe S to afford, in coaction with the crossbar-attaching clamp unit 14 on the shoe, a desired stability assisting the infant to stand upright when the props 28 and 28' are removed.
