ORTHOFEDIC APPARATUS Filed April 25. 1951 In vento'r A from ey Patented Jan. 5, 1954 UNITI-:D STATES PATENT OFFICE ORTHOPEDIC APPARATUS Hurshel L. Coffman,` ClintonlMd.
Application April 23, 1951, Serial-N0. 222,380
4 Claims. l
This invention relates to an` orthopedic, appa.- ratus or device for use by'bedridden patients afrlictedwith various forms of paralysis such asinfantileparalysis and poliomyelitis whereina stiffening or rigidity of the leg muscles occurs which causes the foot to be extended outwardly and downwardly relatively to the leg and wherein the patient lacks muscular control of the foot and leg sulicient to move the foot upwardly toward a position at substantially a right angle to the leg.
it is a primary object of the present invention to provide an apparatus of extremely simple construction which may be applied to the leg and against the foot for urging thev foot back to a normal position and whereby varied tension may be maintained. against* the foot for urging it toward a normal position.
Another object of the invention is to provide an orthopedic apparatus wherein the foot is free for movement in a direction away from the portion of the apparatus in engagement therewith and in a direction toward a normal position and wherein the Afoot engaging portion of the apparatusy will be yieldably drawn toward the foot to follow such movement of the foot back toward a normal position as muscular control of the leg and foot muscles are acquired by the patient, whereby the foot engaging portion will constantly urge the foot toward a lcorrect positionand assist in retaining the foot in any position attained in its movement toward a normal position.
Still a further object of the invention is to provide an apparatus capable of being readily adjusted to increase or decrease the yeldable pressure exerted against the foot and wherein no portionv of the foot is enclosed or confined so that freedomrof the foot and toe muscles ifs-insured to enable the patient to exercise the foot and ankle.
Still a further object of the invention is toprovide an apparatus wherein freedom of the foot for movement toward a normal position is further enhanced by the provision of means .permitting the heel portion of the footto swing in the opposite direction to the toe portion of the foot as the foot pivots on the ankle joint in movingl from an extended abnormal position toward a normal, right-angular position relatively to the leg.
Various other` objects .and advantagesv of .the invention .will hereinafter become more fully apparent from the following ,description of the. drawing, illustrating a presently preferred. em bodiment thereof, and wherein:
Figure 1 is a side elevational viewshowing the apparatus in-an applied position appliedxtoythe. leg and foot of a patient;
lFigure-,2 is a ton plan viewof theapparatnsin its posit-ionof Figure 1 Figure 3 isa'longitudinal substantially lcentralsectional; View of the apparatus illustratedin an appliedposition;
Figure isran' end view of the invention lookins from rightv to left of'Figure 3;
Figure 5 isa cross ,sectional view of theap.- paratusk taken substantially along av planeas indicated by the line 5 5 of Figure 3 and showing the leg in an applied. position .therein.and
Figui-e6 is a perspective viewaof. a. portion of the apparatus shown in a fully extended position.
Referring more specifically to. thedrawing;v the orthopedic apparatus inits entirety is designated generally 'lV and .inclildesany elongated .leg engaging-member 8 ofzsubstantially channel-shapedor U-shaped cross section including. asubstantiallyy natA bottom portion 9 and corresponding upwardly curvedsides lll the upper portionsy oizwhi'ch are substantiahy flat. Asbest illustrated in 'Fig ures 2 and 4, the leg engaging member.8 tapers in width from end-to-end thereof and is provided Heal' ,the narrower end with a. pair of vslots I l: and l2 formed inv each side wall thereof andwhich are spaced a considerable distance from the upper edges of said side, walls. The side Walls I0: are also providedeach with a single slot i3v near the oppositawider end 0f the member 8; andy which are `likewise spaced a substantial distance: from the 1.1131381 edges of the walls l0. Each wall l0 is also provided with akeyhole-shapedslot,I4, whichislots are disposed ,above the slots l3fand betweensaid slotsv I3 and the larger end of thernernberpathe enlarged ends of thekeyhole.- slots I4 being disposed nearer the widerendrof the member 8.
Theapparatus l also includes. a foot engaging plate, designated generally l5 having asubstantially flat bottom I6 and corresponding upstandingside walls I1. The :footengaging member l5 isfnarrower than the narrow end of the legengaging `inenflber 8 and has one: end thereof disposed ,in thenarrowend of; thememgber'. Headed iastenings `Ill extend through the; adjacentlyy upper edges-of the walls lll, and abovev the levely of. thesslotsf l l., tzand; i 3; The root-.plateportion I6 has an inner end forming a heel engaging portion I9 which is disposed inwardly of the axis of the pivots I8 on the opposite side thereof to the major portion of the foot plate bottom I6.
The members 8 and I5 are connected adjacent their remote ends by a pair of adjustable pulling units, each designated generally 20 and each of which is connected to complementary walls I and I1 of the members B and I5. Each pulling unit 20 includes a clevis 2I constituting one end thereof, one end of which clevis is pivotally connected by a pivot pin 22 to the outer end of one of the walls I1, remote to the pivots I8. A flexible elastic member 23 has one end secured in the opposite end of the clevis 2I and the other end of the elastic member 23 is connected to one end of a ball-type chain 24 by a coupling element 25. Each chain 24, which constitutes the opposite end of the pulling device 20 is connected to the Wall I0, complementary to the wall I1 engaged by the clevis 2|, by the chain 24 engaging the keyhole slot I4 of said wall I0, each chain 24 extending outwardly through a keyholeshaped slot I4 and being provided at its terminal with a ring 25. The chains 24 are capable of sliding freely through the enlarged ends of the slots I4 but the balls of the chains 24 are incapable of sliding through the restricted ends of the slots I4 so that the chains 24 may thereby be adjustably connected to the leg engaging member 8 to vary the pull on the foot plate I5.
The orthopedic apparatus 1 also includes a pair of straps 21 and 28 each including an adjustable clasp 29 of any suitable type, herein illustrated as a conventional buckle. The straps 21 and 28 extend across the outer or under side of the bottom portion 9 and the strap 28 then extends inwardly through the slots I3 and over the upper portion of the leg 30 of a patient, which is disposed in the leg engaging member 8 and said strap 28 is secured over the upper portion or shin of the leg 30. As seen in Figure 1, the leg engagin-g member 8 engages the leg 30 below the knee. The strap 21, as illustrated in Figure l, initially extends inwardly through the slots II and is then fastened snugly over the ankle. Figure 1 illustrates substantially the initial position of the foot 3I relatively to the leg 30 of a patient afflicted with paralysis and which frequently causes the foot to be extended outwardly or downwardly with respect to the leg due to stiffening or rigidifying of the muscles of the leg and foot and so that the patient is unable to move the foot upwardly or from right to left of Figure l to a normal position at substantially a right angle to the leg. The apparatus 1 is adapted for use in overcoming this muscular deiiciency and in assisting a paralytic while still bedridden in returning the foot to a normal position and in restoring muscular control to the foot and leg muscles. The leg engaging member 8 is secured around the leg and ankle by the straps 2B and 21, as previously described and as illustrated in Figure l and the foot plate I5 is then swung upwardly from a fully extended position as illustrated in Figure 6 until the sole of the foot bears against the bottom I6 and with the heel of the foot disposed against the heel portion I9 of the bottom IS. The chains 24 are then drawn outwardly through the enlarged portions of the Slots I4 until the stretchable elements 23 have been stretched sufficiently to apply as much pressure to the foot as the patient can reasonably stand, after which the chains are slipped into the restricted portions of the slots I4 so that a ball of each chain will form astop to prevent the chain from slipping inwardly through said slots. The parts will then be in their positions of Figure 1 with the pulling units 20 urging the foot plate I5 to swing upwardly relatively to the leg engaging member 8 in a counterclockwise direction and toward an upright position. The apparatus 1 does not burden the user as the leg engaging member 8 rests upon a bed or other support 32 on which the patient is lying and the foot of the patient is in no way confined by the foot plate I5 except against movement toward an extended position relatively to the leg so that the foot is free to be exercised as much as possible thus enabling the patient to attempt to raise the foot relatively to the leg, which muscular activity is encouraged by the resilient pressure of the pulling units 20 urging the foot plate I5 upwardly and in the same direction. The constant yielding pressure exerted against the foot by the foot plate I 5 and pulling units 20 will gradually cause the foot to move toward a normal position, from its position of Figure 1 to and beyond its position of Figure 3 and as the foot is drawn upwardly or from right to left of Figures 1 and 3, the chains 24 are taken up by means of the slots I4 to take up any lost tension on the elastic elements 23 and so that a proper tension will be maintained by the foot plate I5 against the foot. As the foot plate approaches the position of Figure 3, the strap 21 is removed from the slots I and engaged with the slots I2 so as to engage the leg above the ankle. It will also be noted that as the foot moves toward a natural position under the action of the foot plate I5 and swings from its position of Figure l to and beyond its position of Figure 3, the heel swings downwardly and outwardly as the toe portion of the foot is drawn upwardly and inwardly and the ankle bone assumes a position substantially in longitudinal alignment with the axis of the pivots I8 and relatively to the leg engaging member 8 so that the heel is enabled to swing in one direction as the toe portion of the foot swings in the opposite direction.
It will thus be readily apparent that an orthopedic apparatus of extremely simple construction has been provided which is readily adapted for use by a bedridden paralytic for strengthening the foot and leg muscles to cause the foot to resume a normal position relatively to the leg before the patient has recovered sufliciently to stand or walk, thereby reducing considerably the difliculties involved in enabling a paralytic patient to leave the bed and resume a standing position and to overcome lby exercise the weakened condition of the leg muscles caused by the paralysis and the long period of inactivity of the leg. The apparatus 1 may be formed of various suitable materials such as sheet metal including aluminum or may be formed of other materials including plastics.
Various modifications and changes are contemplated and may obviously be resorted to, without departing from the spirit or scope of the invention as hereinafter defined by the appended claims.
I claim as my invention:
