5 vide an equipment for securely establishing fragments of a fractured bone definitely in proper articulation.

Another object is to provide means for firmly holding skeletal wires or pins that are inserted through bone fragments in definite relative positions.

Further objects and advantages of the inven tion will appearin the following description.

An illustrative embodiment of the invention is shown in the accompanying drawings, in which:

Fig. 1 is a plan view of apparatus in which the invention is embodied;

Fig. 2 is an end elevation projected from Fig. 1;

Fig. 3 is an elevation showing part of the apparatus shown in Fig. 1, parts being in section;

Fig. 4 is a perspective view showing one form of the apparatus including the representation of an injured leg disposed thereon; and

Fig. 5 is a fragmentary elevation of a part of the apparatus in modified form. I

The illustrative embodiment of the invention is similar in some respects and of the character of that disclosed in my previous patent, No. 2,020,262, issued November 5, 1935, and is characterized by the particular arrangement of the various parts and additional fixtures whereby the appliance is adapted for use in skeletal treatment of fractures of the femur.

The present structure has a base frame consisting of end pieces I and 2 spaced apart and connected together by side rods 3. A traction mechanism is mounted in connection with said end pieces consisting of a beam formed by

telescopic members

4 and 5 which are preferably rectangular in cross section. In the member 4 is secured a threaded tube 6 into which extends a threaded operating rod I that extends longitudinally through the member 5 and is provided at its outer end with a knob 8 by which the rod I is manipulated. Upon actuating the rod the member 5 is adjustably moved longitudinally relative to the end piece 2 and the member 4.

' horizontally disposed bracket 9 having thereon a carriage II] that is movable longitudinally on said bracket. The bracket 9 has located therein an operating rod I I provided with a knob II that-has threaded relation with a lug I2 that Upon the member 5 is removably secured ais integral with said carriage and extends up into the bracket through the bottom thereof which is open. The carriage has an upwardly extending threaded post I3 provided with an adjusting member I4 having threaded relation 5 therewith.

Upon the top of the post is loosely mounted a slotted swivel-head I5 adapted to have axial and angular adjustment thereon. A bolt I6 extends through a pair of ears I! on the swivel- 10 head and is provided with a clamp member I8 threaded on the bolt by means of which the swivel head I5 is secured in adjusted positions on the post. By turning the adjusting member I4 upon the post the swivel-head is raised or lowered relative to the post as desired. The upper end of the swivel-head I5 is slotted for thereception of a pin or wire securing bow I9 preferably U-shaped and which is adjustably and removably secured in position in the swivelhead by means of set-screws 20.

Upon one of the side rods 3 is mounted a clamp member 2I having axial and angular adjustment thereon, and provided with .a clamp screw 22 for securing it in adjusted positions. The clamp member has secured thereon a post 23 upon which is mounted a'bracket 24 adapted to have axial and angular adjustment thereon; there being provided a thumb-screw 25 for securing the bracket in adjusted position on said post.

In the free end'of the bracket is mounted a swivel-head 26 disposed to be adjustably'turned upon a horizontal axis, there being provided a thumb-screw 21 for securing. said swivel-head in adjusted positions relative to said bracket.

The swivel-head 26' is slotted for the reception of a pin or wire securing bow 28, similar to the bow I9, and is also provided with set-screws by which said bow is secured in adjusted positions in the swivel-head.

Each of the swivel-heads I5 and 26 have thumb-screws 29 that extend through the corresponding swivel-heads adjacent the curved inner perimeter of the bows located in the grooved ends of said swivel-heads, permitting adjustable movements of the bows and preventing removal thereof while said thumb-screws are in place. However, upon removal of the thumb-screws and loosening of the set-screws 20 the bows may be readily detached from their swivel-heads.

In Fig. 5 is illustrated a modified form of a bracket 30 for support of the swivel-head I5 instead of the .bracket 9, previously referred to,

especially when an adjustable carriage on the bracket is not required. In this instance the bracket 30 is provided with a threaded post 3| having thereon an adjusting member 32. The swivel-head I5 is positioned on the upper end of the post 3| and is raised or lowered thereon to the desired elevation by manipulating the adjusting member 32, and the swivel-head is turned angularly upon the axis of the post to the desired position and is there secured by tightening the clamping member I8.

Each of the

brackets

9 and 30 are provided at one end thereof with a hinged clamp 33 having a securing member 34 for holding the same in closed position relative to the bracket. By this means said brackets are readily attachable to and removable from the telescopic member 5.

As a means for sustaining one end of the base frame in elevated positions and for supporting a distal portion of an injured leg of a patient, there is provided an appliance preferably consisting of a U-shaped drop having side uprights 35 that are contiguous with a connecting base portion 36. The uprights extend through openings 31 in the end piece 2 and are secured in adjusted positions in said end piece by means of set-screws 38. A cross-piece 39 is adjustably mounted upon said uprights and is provided in its middle portion with a cradle 40 to provide a rest forthe injured member. By this arrangement when the appliance is positioned on a bed or table the base frame is arranged in the best position selected by the surgeon, and also, the distal part of the injured leg is supported in the most comfortable position.

Operation In using the appliance, for example, in skeletal treatment for fractures of the femur, the injured leg is positioned over the base frame with its distal part resting in the cradle 40. The clamp member 2| is then adjusted upon its supporting side rod 3; the bracket 24 is adjusted upon the post 23 that projects from said clamp member; the swivel-head 26 is adjustably turned upon its axis to a desired position; and the how 28 is adjusted in said swivel-head so that its outer ends are positioned respectively above and beneath the greater trochanter of the femur. A pin or wire 4|, preferably of the Steinmann or Kirschner type, is then introduced through the flesh about the proximal end of the femur and through the greater trochanter thereof by the usual method employed by surgeons, the end portions of the pin or wire being then secured in the ends of the bow 28. A similar pin or wire 42 is then introduced through the flesh surrounding the distal portion of the femur and through the portion thereof adjacent its condyles, the ends of the pin or wire being then secured in the outer ends of the bow IS. The pins or wires thus introduced and secured in their respective bows are adjustably positioned relative to each other to obtain proper apposition of the bone fragments by manipulating the knob 8 to obtain sufficient extension to permit alinement of the bone fragments and then adjusting the bows respectively, or one of them, in their swivel-heads in which they are supported to effect proper relative rotation of the bone fragments so that upon further manipulation of the knob the opposing ends of the bone fragments are brought into proper alinement where they are definitely held for a recovery period.

The operation is completed by applying a plaster cast (not shown) encompassing the injured member and adjacent exposed portions of the pins 41 and 42 after which the appliance is removed except said pins or wires which remain imbedded in the cast.
