This invention relates t an orthopedic device, and particularly to such .a device by means of which the human foot may be held and manipulated to force the foot and leg into any desired position for orthopedic work.

One of the objects of this invention is the provision of an improved orthopedic device for manipulating the foot and/or the leg of .a p-atient. A further object yof the invention is the provision of such a deviceA wherein the heel portion and sole portion of the foot are firmly held for manipulation with respect to each other. Another object of the invention is the provision of such a device wherein there is provided an arch elevating member for manipulating the arch of the foot. Another object of the invention is the provision of such a device wherein the heel of the foot may be manipulated in order to align broken bones and for similar purposes. Other objects and features of the invention will become apparent in the following description and claims when .considered in conjunction with vthe accompanying drawings.

Of the drawings: Fig. 1 is a side elevation of one embodiment of the orthopedic device including the base member or stand which forms a part thereof; Fig. 2 is a longitudinal .section taken along line 2 2 of Fig. l; Fig. 3 is a plan View of the `head member of the device; Fig. 4 is a bottom view of said head member; Fig. 5 is a section taken along line 5-5 of Fig. 3 and showing a human foot secured to the head member; and Fig. 6 is a section taken .along line 6 6 of Fig. 5.

The orthopedic device illustrated in the accompanying drawings comprises a base member or stand I, an extension, II movable `longitudinally with respect to said base member, .a second extension l2 attached to the first extension II and movable arcuately with respect to the rstextension and a head member I3 movably mounted on the second extension I2.

The base member I0 is provided with a hollow vertical pipe portion Illa having an open top into which extends a threaded rod IIa that forms a part of the iirst extension il. Located at the top of the pipe portion Illa there is provided a threaded nut I4 whosethreads engage those of the rod IIa. Thus nut I4 is adapted to bear against the upper end of the pipe section Illa and is provided Awith four equally spaced outwardly extending rods I 4a by means of which the nut may be turned. When this nut is turned, the top part of the orthopedic device is moved relative to the base member I0. In order to lock this top part in a desired position,v there is provided a threaded bolt lI5 extending through a side of the pipe portion Illa at the top thereof and bearing against a block I5 which is adapted to bear against the threaded rod I Ia, and prevent it from turning by frictional engagement therewith. The bolt I5 is provided with an outer head 15a on which are located four outwardly extending rods or pins I5b, these pins providing leverage for turning the bolt I5.

The top portion of the first extension II is provided with a substantially circular flat section I Ib that is arranged to bear against a similar flat section l2@ on the bottom of the second .extension I2. These two sections IIb and 12a are held together by means 4of a threaded bolt I'I extending through the section I2a and engaging the section IIb. This bolt is provided with a head I'Icll to which is rotatably attached a lever I3 s0 that the bolt may be turned. The flat sections I Ib and vI2a permit arcuate movement of the second extension I2 withrespect to the rst extension II. The two extensions may be locked together in a desired position by turning the bolt ITI by means of the lever I8.

The second extension I 2 carries the head I3 and is attached to the head member by means of a ball and socket joint I9. This ball and socket joint permits pivotal movement of the head member I3 with respect to the remainder of the apparatus. When the head member has been moved to the desired position, it may be clamped in this position by turning a lever 20 which threadedly engages the ball and socket joint.

The head member I3 comprises a heel portion 2I and a sole portion 22. These two portions are connected together by means of a hinge structure 23 located at their adjacent ends. The two portions can thus be moved relative to each other in their common plane.

The heel portion 2I comprises a heel redressor base having aligned outwardly extending handles 24 and a curved heel housing 25. This heel housing is adapted to receive the heel of the foot and is provided with a bottom Aheel plate 26, a pair of side heel plates 2'I and 28, and a rear heel plate 29. One side heel plate 2'I is mounted on a pin 30 which is slidably held in a tubular housing 3l extending outwardly from the heel housing 25. This tubular housing is provided with a threaded bolt 32 which engages threads on the interior of the tubular housing 3l for moving the pin Bil and heel plate 2l toward and away from the other heel plates. The bolt 32 is provided with a handle 32a at its outer end to aid in turning the bolt. In order that the heel plate 2'I will be constantly urged toward its outermost position there is provided a second pin 33 attached to the heel plate 21 and extending through the heel housing 25. Located around the outer end of this second pin 33 there is provided a compression spring 34 having one end bearing against the heel housing and the other end bearing against a washer 35 secured to the outer extremity of the pin 33. This compression spring serves to urge the side heel plate 21 in an outward direction. In order to lock the bolt 32 in any given position, there is provided a nut 36 on this bolt that may be turned to a position where it bears against the outer end of the tubular housing 3|.

The other side heel plate 28 is provided with a similar tubular housing 31, bolt 38, pin 39, compression spring 40, second pin 4| and nut 42. The rear heel plate 29 is provided with similar elements by means of which this heel plate can also be moved in and out.

The bottom heel plate 2B is likewise movably mounted on extension 43 that extends through an opening 44 in the heel portion 2| This extension 43 is rotatably mounted by means of a hinge 45 to the bottom of the heel plate 26. The extension 43 is provided with two outwardly extending Wings 43a each of which threadably holds a bolt 46 whose inner end bears against the bottom of the bottom heel plate 26. By adjusting these bolts 46, the bottom heel plate 26 may be locked in any desired position so as to support firmly the heel of the foot.

The bottom end of the extension 43 is engaged by a bolt 41 having a head 41a, thereon. This bolt is held in a bridge 48 that is attached to the bottom of the heel portion 2| of the head member. The bottom heel plate 2B may be raised up or down by turning the bolt 41. A compression spring 49 is positioned around the extension 43 with this compression spring bearing against a base 50 and a washer 5| on the extension 43. This spring serves to urge the bottom heel plate 26 towards its lowermost position as the base 50 is anchored to the bottom of the heel portion 2|. The side heel plates, bottom heel plate, and rear heel plate may be moved forward or backward as has been described. The two side plates may be used for applying lateral compression to the heel, the rear plate to apply posterior compression and the lower plate for applying plantar compression. The bottom heel plate may also be tilted, as has been described, for proper angulation of the heel bone.

The top of the curved heel housing 25 is provided with a rim 25a separated from the remainder of the housing. This rim may be used to anchor a strap 52, which passes over the foot and holds the heel securely in place.

The front of the heel portion 2| is provided with a downwardly extending tubular member 53 which is held in a mounting 54 at the adjacent end of the sole portion 22. This arrangement permits rotation of the sole portion 22 with respect to the heel portion. The tubular member '53 is held in place within the mounting 54 by means of a cap member 55 which is removably attached to the tubular member by means of a pair of aligned stud bolts 55a. The tubular member 53 not only serves as a portion of a hinge by means of which the sole portion 22 may be turned relative to the heel portion 2|, but also Serves to receive the stem 56a of an arch elevating member 56 that is adapted to be arranged beneath the arch of the foot as is shown in Fig. 5. The stem 56a ts loosely within the tubular member 53 and may readily be withdrawn therefrom. Two arch elevating members are ordinarily provided, with one being shaped to conform to the arch of a right foot and the other to conform to the arch of a left foot. The arch elevating member is moved up or down by means of a threaded bolt 51 having a head 51al thereon and extending through the cap member 55 and bearing against the bottom of the stem 56a.

A foot 58 is held in place in the apparatus by means of the strap 52 and a dorsal strap 59. Each end oi the dorsal strap 59 is arranged to be held by an eccentric clamping rod 6|] that is rotatably held in a bracket 6|. The two brackets 6| are connected by parallel webs 62 extending therebetween. The parallel webs 62 are provided with a tubular member 63 extending between and attached to the webs 62. This tubular member has its longitudinal 'axis substantially at right angles to the longitudinal axes of the web 62. The bottom of the sole portion 22 is provided with a downwardly extending stem 64 that is slidably held within the tubular member 63. The unitary assembly of eccentric clamping rod 60, brackets 6 i, webs 62 and tubular member 63 may be moved away from or toward the sole portion 22 by turning a threaded bolt 65 that is provided with a head 65a. This bolt extends through the bottom end of the tubular member 63 and bears against the bottom of the stem 64. By means of this movement, tension may be regulated in the dorsal strap 59 and thus the amount of force applied to the foot may be controlled. The movement of the above member is guided by providing a downwardly extending pin 15 on the bottom of the sole portion 22 with this pin slidably engaging an extension 62a on one of the webs 62. This extension and pin prevent rotation of the movable unit` Each eccentric clamping rod 60 is provided with a handle portion 60o; with this handle portion being arranged at substantially right angles to the remainder of the clamping rod. The handle portions 66a are located beneath the sole portion 22 and extend lgenerally toward each other. Forcel is applied to the clamping rods 60 to hold the dorsal strap between the rod and the brackets 6| by providing a tension spring 66 extending between each handle portion 66a and the bottom surface of the sole portion ,22, as is shown in Figs. 4 and 5. These springs also serve to urge the unit which hold the ends of the dorsal strap toward the sole portion 22.

In order to hold the heel portion 2| and the sole portion 22 in a desired position relative to each other, there is provided a rod 61 rotatably mounted on the heel portion 2| and extending through and slidably engaging a mounting 68 on the bottom of the sole portion 22 near the free end thereof. The rod member and mounting may be locked together by means of a threaded bolt 69 located in the mounting 68 and arranged to bear against a side of the rod 61. This bolt is provided with a handle portion 69a for ease in turning the rod. The rod 61 may also be used to manipulate the sole portion 22 relative to the heel portion 2|.

The free end of the sole portion 22 is provided with an outwardly extending handle portion 22a in order to aid in manipulating the sole portion relative to the heel portion.

Located immediately behind the handle portion 22a there is provided an arcuate traction splint anchor 10 with the concave side thereof toward the heel portion 2i of the device. This anchor is terioitibiai margin" fracture; for .reductionof the posterior tibial vmargin fracture; for reduction of jdiastasis of the proximal and distal tibiobular joints; and for ree'establishing symmetrical anatomicalarticular relations of all structures of the foot, ankle and leg. The device may be used to align on reconform the skeletal structures of the foot to normal positions before applying a plaster orlother castto vthe foot.

The orthopedic device described herein may be attached to an ordinary tractiontable prior to use. Thus the iirs't extension Il which is shown attached to the base member I0' may be made square, rectangular or any other desired shape `in order to be held in an opening usually i provided in such tables; v

means for locking the head member in a desired position, a hinge structure uniting the heel pore tion and sole portion for movement relative to each other substantially in the plane lof the bot#- tom of the foot when the foot is in place on the head member, a rod member rotatably mounted on the heel portion and slidably engaging a mounting on the sole portion, means for locking the-rod member land mounting together to prevent movement between the two portions after they have been arranged in a desired alignment, a curved heelhousing on the heel portion adapted to receive said heel, a bottom heel plate in said housing adapted to'contact the bottom of the heel, a pair of side heel plates in said housing adapted to contact the lateral sides of the heel, a rear heel plate in said housing adapted to contact the rear of the heel, each of said heel plates having'a contacting surface shaped to conform substantially to the corresponding part of the heel, meansl for moving each heel plate toward and away from the others, means on said heel housing for attaching a strap member to pass around the foot and hold the heel in pla-ce, an arch elevating member movably mounted on said head member and having a surface adapted to contact the arch of the foot, means for moving the arch elevating member toward and away from the head member, a pair of elongated spring pressed eccentric clamping rods arranged beneath said sole portion and substantially parallel to made of a piece of angle metal and may be bolted to the sole portion by means of a pair of bolts a. These bolts pass through two holes in the sole portion and corresponding holes in the anchor 10. The anchor is supplied with a pair of pins 10b with each pin being near an outer end of the anchor, as is shown in Fig. 4. If it is desired to position the anchor 10 laterally in either direction from the position shown in Fig.' 4, one pin 10b may be held in one hole in the sole portion and the adjacent hole in the anchor may be aligned with the similar hole in the sole portion. One bolt 10a may then be used extending through both holes to retain the anchor in place. If desired a slot may be used instead of the plurality of holes and pins in the anchor 10 for attaching it to the sole portion.

The top portion of the anchor is provided with a series of aligned holes 79e with these holes being used for the attachment of anchor splints to the bones of the foot.

In using the orthopedic device, a foot is arranged in the device in the position shown in Fig. 5. The foot is held in place by means of the strap 52 and dorsal strap 59. The brackets 6I and clamping rods 60 are made of suflicient length so that the dorsal strap 59 may be moved to a desired position longitudinally of the feet. Thus the dorsal strap may bear against either of the phalangeal, metatarsal or tarsal regions of the foot. Pressure may be applied to the foot through the dorsal strap 59 by turning the bolt 65. This regulates the tension in the dorsal strap. Pressure on the heel may be applied by moving the side heel plates 21 and 28, the rear heel plate 29 or the bottom heel plate 25 toward or away from each other. If it is desired to manipulate the foot the bolt 69 may be loosened in its mounting 6B so that the rod 61 is permitted to slide freely within the mounting 68. The sole portion 22 may then be moved back and forth around the tubular member 53 which serves as a hinge connecting the sole portion to the heel portion. The pressure of this movement is transmitted to the foot through the dorsal strap 59. The muscles of the foot and leg may be stretched or otherwise manipulated by loosening the ball and socket joint I9 and moving the entire head member I3 relative to the remainder of the device.

In order to give stability to the apparatus, the pipe portion Illa of the base I Il has its bottom end removably held in a collar Inh which in turn is attached to the opposite semi-circular segments IDc and Id of tubing. This arrangement permits the device to be brought into close apposition with an operating table or a treatment chair. The orthopedic device of this invention adapts the conventional treatment or operating table ordinarily used by doctors into a traction table for orthopedic work on the lower extremities. The device serves as an adjustable support which permits traction and positioning for reduction of fractures, open or closed, and the application of plaster casts` In using the device, it is brought up to the treatment chair or table and by the various adjustments previously described, into position to receive the foot.

The side heel plates 21 and 28, bottom heel plate 26 and rear heel plate 29 may be adjusted as previously described to hold the heel for various manipulative procedures and to reduce fractures of the heel bone (calcaneous or oscalcis). The rear heel plate may be moved forward or backward thereby acting as an adjustor to put the foot into proper relationship to the sole portion 22 of the device. The bottom heel plate 26 may be tilted longitudinally by means of the adjusting screws 4-6 to re-establish normal tuberjoint angle of the heel bone when this bone is broken, or to manipulate the heel bone.

The retaining heel strap 52 may be secured to any portion of the rim 25a and tightened to any desired tension, thus holding the rear part of the foot in a desired position or it may be used to assist the heel plates to hold the rear part of the foot in position.

In the various manipulations and tractions, the front part of the foot is held by the dorsal strap 59. This dorsal strap is automatically held at any point by the eccentric clamping rods and any desired tension applied to it by use of the bolt 65. The heads 41a, 51a and 65a of the various bolts are preferably all the same size so that they may be engaged by a single tool when it is desired to apply a high degree of pressure to a desired portion of the foot.

The dorsal strap 59 permits any desired pressure to be applied to the front part of the foot to reduce or break down a pes cavis or Schaeiers foot. While being held in this manner, the front and rear parts of the foot may be forced in any direction.

One of the important functions of the orthopedic device described and claimed herein is to stretch the Achilles tendon. This is accomplished by dorsiflexing the foot on the leg by forcefully moving the front handle 22a upward and backward to move the head member around the ball and socket joint I 9. If the head member is moved up and back, the tendon is stretched. The anterior group of muscles of the leg are stretched by an opposite movement. The foot may also be adducted tc stretch the lateral group of muscles of the leg, and abducted to stretch the deep posterior group of muscles thereof.

With these combinations of motions, the device can be used to manipulate the foot to correct deformities such as talipes equinus (varus and valgus) and to correct club type of foot talipes calcaneous. In correcting the above types of deformities and additional deformities such as metatarsus, varus and latus, the device is capable of stretching all muscles, fascia and ligaments of the foot and leg and of breaking up adhesions of the foot and leg, as well as stretching all joint capsules of the foot, ankle and leg.

This device readily affords a controllable means of releasing contractures by means of progressive lengthening through stretching to allow the normal extent of motion. This in turn relieves the compression of the peripheral nerve pathways.

The device may be used to re-establish vertical Helbing line in rigid calcaneal valgus and varus positions. It may be used to realign calcaneal cuboid talus junction. It may be used to manipulate or open up the subastragular joint in comminuted fracture of the os calcis, also the subcrural joint in fracture of the ankle or astragulus.

The orthopedic device disclosed and claimed herein may also be used to break up a malunited fracture of the foot or ankle; to correct dislocation of the ankle in backward, forward, medial or lateral dislocations; for closed reduction of dislocation of astragulus (talus), scaphoid (navicular) and cuboid; for closed reduction of one or more dislocated. metatarsal bones; for closed reduction of metatarsal phalangeal articular dislocation; for closed reduction of interphalangeal articular dislocation; for reduction of the aneach other and to the longitudinal axis of said sole portion, said rods being mounted on a movable mounting member and being adapted to receive and hold the ends of a dorsal strap passing over the instep of the foot by pressing said ends against portions of said mounting member, with the clamping rods being of sufficient length to permit the dorsal strap to bear selectively against the .phalangeaL metatarsal and tarsal regions of the foot, means for moving said mounting member that carries the clamping rods toward and away from said foot portion for regulating tension in said dorsal strap, an arcuate traction splint anchor adjacent the free end of the sole portion with the concave side thereof being on the side nearer to the center of the sole portion, said anchor being capable of being moved laterally to a desired position with respect to said sole portion, and handle means on the heel portion and sole portion to assist in moving said portions with respect to said base member and with respect to each other.

10. An orthopedic device comprising a base member, an extension on said base member movable longitudinally with respect to the base member, a second extension on the first extension movable arcuately with respect to the rst extension, a head member mounted on said second extension for universal movement with respect thereto, said head member being adapted to receive a human foot thereon, means on said head member for clamping said foot thereon, and means for rigidly clamping the first extension on the base member, the second extension on the first extension and the head member on the second extension.
