Application February 24, 1932, Serial No. 594,795

10 Claims.

'I'his invention relates to a splint to be used in fractures of the lower extremity.

Usually when a bone of theV lower extremity is fractured the pull of the muscles, which are under constant tension, causes an overriding of the ends of the fractured bone. This, in turn, causes shortening of the leg combined with lateral, anterior or posteriordisplacement of the ends of the fractured bone. The aim of treatment is to correct this deformity in every direction and to hold the ends of the fractured bone in this corrected position until union of the ends of the fractured bone takes place. Ordinarily this overriding of the ends of a fractured bone is overcome by applying adhesive straps to the leg to which are attached weights which gradually tire out the muscles and in four or ve days overcome the overriding of the fractured bone. It would be to the advantage of the patient if this overriding could be corrected at once, but if sufficient weight is applied to the adhesive straps to accomplish this, the adhesive straps will pull off of the leg as it will not stand a trac'tive force greater than forty pounds. It usually requires a much greater tractive force than forty pounds to accomplish this. After the overriding of the ends of the fractured bone has been corrected a constant tractive force is still necessary to keep the fractured ends from overriding again until union takes place. But it does not require as great a tractive force to hold the position after it is corrected as it does to do the initial correcting.

This splint provides means for applying any amount of tractive force that may be necessary to overcome any overriding of the ends of the fractured bone, separate and apart from the adhesive straps. After the overriding is overcome by this means, then weight is applied to the adhesive straps to hold the bones in the corrected position until healing takes place.

Means are also provided to correct any lateral, anterior, or posterior displacement that may be present. f

Means are also provided -so that, in any case.

(Cl. 12S-85) tion can be corrected and held until union takes place.

Means are also provided in connection with the ring of this splint whereby the patient is-prevented from turning the splint over, By having 5 the ring so fixed, the foot end of the splint can be swung from an overhead frame, and it is not necessary to haveany support at the foot end of the splint to prevent the patient from turning the splint over. Any attachment at the foot vend of the splint for this purpose prevents the swinging of this end of the splint by overhead means, which is the ideal way to do.'

'I'he non-turning means also by resting on the bed interferes with changing the bed linen. Arrangement is made so that the rod on inner side of the splint can be turned down toward the foot and permit the use of bed pan Without having to unscrew the rod.

This splint also provides means for holding the 2o ends of the adhesive tape at the foot, and by being adjustable, can be adjusted to any width of foot so that adhesive tapes will not press on ankle bones. It also provides means for attaching tractive means to the adhesive tapes.

This splint also provides cus which slip on the lateral bars and have means for securely holding the webbing which supports the leg, means for easily adjusting this webbing, and also means for applying lateral, anterior and posterior pressure to any part of the leg. f

This splint also provides a foot piece which holds the foot up, prevents the foot drop, it also prevents the foot from turning to the right or left,

thus keeping the foot in proper alinement with the leg at all times. It further prevents the bed cover from resting on patients toes.

This splint can be used for right orleft leg by simpl-y turning ring over. By the use of rings of varying circumferences and lateral bars of varying lengths, a splint of suitable size can be assembled for any patient, as all parts are standardized for the rectangular bars.

Figure 19 is a perspective view of the turnbuckle for spreading the leg piercing pins apart from each other;

Figure 20 is a view of the bone piercing member made integral and having the same general outline as the sectional pin in Figure 18.

Referring more specifically to the drawings, the numeral I0 indicates a ring adapted to t around the base of the leg and this member I0 has projections I I and I2 projecting from one side thereof and also projections I3 and I4 projecting from another side thereof and the ring IIl is covered with any suitable resilient material such as felt, cloth, leather or rubber and the like indicated by I5. By turning the ring I0 over, it can be used for right or left leg.

The members I I and I3 are threaded interiorly and have secured therein a member I6 which member I6 has threadably secured therein an extended rcd I1. The members I2 and I4 are rigid with relation to member I0 and are adapted to threadably receive an extended rod I8, the purpose of rods I1 and I8 being to prevent turning of the leg of the patient and the splint while the patient is reclining in bed. It also vpermits the foot end of the splint to be swung by a rope or other means from an overhead frame and still prevents patient from turning splint over. The purpose of having rod I1 turnably mounted as shown in Figure 9, is for swinging this rod out of the position shown in Figures 1 and` 2 where they occupy a parallel position to the dotted line angular position shown in Figure 2 so that this member I1 can be swung out of obstructive position when the patient desires to use a bed pan.

Ring member I0 has a bent portion indicated by reference character 28 which is adapted to fit the pubic bone. Ring member Ill has projecting therefrom a portion 2I pivotally mounted with a plurality of holes therein to which is adapted to be secured rectangular hollow side member 23 by means of a screw 22 piercing members 2I and 23.

Also a projection 24 extends from the other side of ring member` Ill and has pivotally mounted as at 25 a member 26 which has `a plurality of holes therein thru which a screw 21 may be passed, said screw also penetrating side member 5 28 which extends the same distance as side member 23 and forms the two main side members of my splint. Y

Adjustably mounted on the members 23 and 28 are a plurality of buckle members 29 which l0 buckle members 29 have a set screw 30 in the lower portion thereof adapted to be used for clamping the buckle member 29 onto the members 23 or the member 28 as the case may be. These buckle members 29 have slots 3| and 32 therein in an up- 15 wardly projecting portion 34, and this buckle member has laterally projecting portions 35 and 36 (see Fig. 12) having a -pin 38 therein in which is pivotally mounted a serrated clamping member 31. Ihese buckle ymembers 29 are adapted to sup- 20 port suitable web material 40 or any other suitable material for supporting the leg between the side members 23 and 28` When used as an ordinary support, the piece of fabric 40 is buckled by means of buckle member 25 31 and it pases thru the lower slot 32 and beneath the leg and thru slot 32 on the other buckle member and passes under the serrated clamping member 31 to secure the lsai-ne as an ordinary support. 30

If lateral traction is desired to be applied to the leg where the bone is out of alinement so as to bring the ends of the bone into alinement to cause j a proper reknitting of the bone at the fractured point, then the web 40 (see Fig. 3) is secured 35 under the outside buckle 29 and is passed beneath the leg and thru lower slot 32 in the inside buckle back thru the upper slot 3I of the inside buckle andagain beneath the leg and around on top of the leg and over the top of projection 34 o'f 40 inside buckle and secured in position by the serrated clamping means on the inside buckle whereby lateral traction will be applied `to pull that portion of the leg inwardly toward the other leg, whereas, if opposite lateral traction is-desired to 45 be applied, the webbing 40 would be placed around the leg in the opposite direction.

A suitable foot board 4I is adapted to be secured to the side members 23 and 28 by means of cuffs 42 and 43 being adjustably secured by 5o means of set screws 44 and 45 on members 28 and 23 and these members 42 and 43 have upwardly projecting spaced lugs 46 and 41 for lug 42 and 48 and 49 for lug 43 and a suitable bolt 50 is passed thru the portions 48 and 49 and another 5:, suitable bolt 5I is passed thru portions 46 and 41 thru slots 52 and 53 respectively to secure foot board 4I in position.

Foot board 4I has a plurality of slots 54 on one side thereof and another set of slots 55 on the 60 other side thereof thru which supporting means 56 maybe secured and passed around the upper portion of the foot of the patient for holding it in' upright position and preventing the foot r from turning to right or left. The foot board 4I has a downwardly projecting central portion '51 which is narrow enouglr to allow the pieces overlapped at its edges, in which overlapping portion the member 63 is adapted to have a sliding iit.

Member 64 has a slot 65 therein and member 63 also has a slot 66 therein which is pierced by a bolt 61 having a thumb nut 68 thereon which bolt is shouldered as at 69 and has a hook 10 thereon which is adapted to be engaged by a cord 12 which is adapted to be passed over a pulley 13 secured in brackets 14 and 15 secured as at 1B and 11 to cross member 18 which is secured to ends of members 23 and 28 by means of thumb nuts 19 and 80 respectively.

The ends of members 23 and 28 are plugged and are interiorly threaded to threadably receive the thumb nuts 19 and 80. Thumbnuts 19 and 80 penetrate elongated slots 83 and 84 in member 18 whereby the distance between the ends of members 23 and 28 may be adjusted. The cord 12 extends downwardly and has a suitable weight 8| secured thereon to which may be added any desired additional weights 82 to supply a steady tractive force to the leg with the splint.

A conventional method of suspending the end of the splint is by means of suspending it from the bed, ceiling, and the like, but if desired, I

may support the ends of members=23 and128 byV having a. plate 85 to' whichis secured a bracket 86 which has an upturned inturned portion to which is pivotally secured a member 81 by means of bolt and thumb nut 88, said member 81 having a plurality of holes 89 therein, wherein a cuff 98 may be adjusted by means of thumb bolts 9| and 92 and the opening 93 is adapted to receive the member 23 or member 28 as the case may be as one o'f these arrangements as shown in Figure 4 will be disposed on each of the members 23 and 28 for supporting the leg of the patient in elevated position if desired, and the angle of elevation may be regulated by means of holes 89 and the cuff 90.

In order tol apply any amount of tractive force that may be necessary to overcome the overriding of the fractured ends of a bone, or to reduce a dislocation of a bone, I have devised attachment shown in Figure l0. This will apply any amount of tractive force necessary for this purpose, separate and apart from the adhesive straps which are to carry the continuous traction until union is secured, for usually these adhesive straps will pull off of the leg if suicient traction is applied to them to produce immediate reduction of overriding or dislocation. By partially loosening bolts 80 and 19, this attachment is slipped on and held to end piece 18 by tightening bolts 88 and 19. Then pieces of webbing 95 and 96 are looped around lower end of leg as shown at 91 and 98.

The above described initial traction is applied after the adhesive is applied to the leg as these straps or webbing 95 and 96 are passed thru a slot 99 in a round member |00 rotatably mounted in a U`shaped bracket |0| which bracket is secured to end piece18 by thumb screws 19 and 80, and one end of round member |08 has mounted thereon a ratchet wheel |02 with a pawl |03 pivoted as at |04 and spring pressed by spring |05 to cause it to ride against ratchet |02 at all times.

The member has a squared portion |06 over which the squared hole |01 of wrench |08 is adapted to be fitted and after the web members 95 and 96 are passed thru slot 99, rotation can be imparted to member |00 and any desired degree of pull can be applied to the leg because the pull is not being exerted on the adhesivev but directly to the leg.

' After the required amount of force has been applied to overcome any overriding of the ends of the fractured bone, then the member composed of portions 63 and 64 can be placed in position as shown in Figures l and 2 and the elastic 58 and 59 is passedthru buckles 6| and 62 and secured as shown in Figure 2 and the Weight can be attached thereto and after this is done the tractive force exerted by round member |00 and webs 95 and 96 can be released and thus the bone can be properly set and aligned immediately after treatment is begun without waiting several days for the pulling force of the weight or a spring exerting a force below thirty ve pounds to cause proper alinement of the bone.

In Figures to 20 inclusive, is shown an attachment on bars 23 and 28 which can be used for reducing and holding the fractured ends of a bone in those cases having extensive injuries to the soft parts, which would prohibit the use of adhesive ror other straps for applying the tractive force, or for any other cause where the fracture could not be reduced and held by external tractive measure.

Figure-#.15 shows the carrying cuffs ||0, which are more fully shown in Figure 17.

Each member ||0 is adapted to be secured in adjusted position on members 23 and 28 respec-tively by means of a thumb nut ||4 appearing in the botom of each of said members. Each of said members has a portion ||5 which has a passageway therethrough similar to the passageway of port-ion 29 of the buckle adapted to have a. sl'ding fit on members 23 and 28 respectively.

On the upper portion of each of these members ||0, vertically disposed slots I' occur and these are adapted to receive the squared portions ||1 of threaded members ||8 or ||9 as the care may be, said member ||9 having a squared opposite direction so that the pair of members i ||0 may be spread apart from each other.

The upper portion of each of these members |||l has a transversely disposed slot |22 therein and a threaded bolt |23 is mounted in vertical relation and has a nut |24 mounted in slot |22. The bolt |23 projects downwardly and is pierced at its lower end by one of the pins |25 which pin has vertical movement in vertical slot |29, said pin having a shoulder |26 thereon into which is threadably secured the piercing pin |21 which pierces the bone of the leg and this pin |21 has a hele |28 therein thru which a small pin or nail may be placed for engaging the same to pull the pn |21 from the leg when it is desired to move the pin from the bone of the leg.

Portion |25 is threaded and has mounted thereonanut |30 by means of which the portion |25 with its shoulder |26 may be advanced against the bone for exerting lateral pressure thereon. The pc-rtion |25 also has a hole |3| therein thru which a pin or other suitable means may be inserted for withdrawing this from the esh portion of the leg when it is desired to disassemble the parts from the leg after the bone has healed andthe treating operation is over.

If desired, the piercing means can be made all in one piece as shown in Figure 20 where portions |21a and |25a are integral and have a shoulder portion 26a; integral therewith. One reason for making this piercing pin in two parts is that it can be separated and withdrawn from the bone without drawing exposed portions of the pin thru the bone.

In the drawings andspeciflcation, there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth in the appended claims.
