the spirit of Patented Feb. 2 1932 UNITED STATES PETER B. McoRA'xEN, or OAKLAND, CALIFORNIA, Assamese can]: r. ionnsnnn CATHERINE rAYN'rER, BOTH. on en ssyAL nY, CALIFORNIA h ADJUsTABLn fsrnI'nrf Application filed May 25, lll t fh'iserial lvo. 539,733.

This invention relates to surgical appliances, especially those adapted for reducing 'members with the lower end of the other anchor member.

The object of the invention is to provide a simple and effective splint of the type which employs the sound limb in counter-resistance to the tension-on the broken limb.

In the accompanying drawings, to which reference is made, the appliance is shown in its preferred form, it being understood that changes may be made without depart ng from claims hereunto appended. g

In the drawings, 7 Fig. 1 is an elevation of the splint, the full lines showing it in normal shape ready to be initially adjusted and applied, and the dotted lines showing its shape after being set. Fig. 2 is a fragmentary detail looking own on top from the line 2-2 of Fig. 1.

Fig. 3 is a front elevation showing in full and dotted lines a modification in direction of the setting-member.

Fig. 4 is a view showing the application of the device to the limbs of a patient.

1 is the anchor member for the broken limb,

. and 2 is the anchor member for the sound limb. These members are rigid plates of suit able dimensions adapted for fixed incorporation within casts applied to the limbs of the patient. V

Upon the inner face of each anchor member near the upper and lower ends, are ears 3 to which are pivotally fitted by mill-headed pins 4, the coupling nuts 5. H

Between theupper pair of nuts 5 is fitted the upper tie-member. 6, I the ends ofsaid member being provided with right and -,left.

the invention as defined in the hand threads,respectively, for engaging the correspondingly threaded nuts. Upon thetie-member 6=is a fin ger grip 7 whereby' said member may-be conveniently" turned onits axis, Of-"determining the initial-separation ofthe upper ends of the anchor members. i

. Betweenthe lower pair of nuts 5- is fitted the lower tieg'member 8* which consists of two aligned sections, one right-hand thread ed andheother left-hand'threademthe adjacent ends'of-thetwo sections being fitted within a correspondingly threaded turn buckle nut 9-, thus providing for 'the initial separation of the lower ends of the' 'anchOr members; .1 a I The='pi\ 7jotpin 4 at-the upper end'oflbne of' the'an'chor members andyat the lower end'of the other anchor member are long enough to pivotally receive the" coupling-nuts 10 in which "are fitted the ;aligned sectionsof the setting-member 11, said sections being right and -leffiha'nd threaded, respectively, and carry at their {adjacent or meeting endthe turn-buckle nut 12. I

Although the appliance as a whole, in its simplicity and eifectivenes's is adapted for use, regardless of whether saidfsetting-mem ber ll 'extends'from the upper end of the broken-limb anchor to the" lower end of the sound-limb anchor, as shown in Fig. 3, or Vextendsifrom the'upperend ofthe sound-limb "anchor to the-lower endof the-broke'n-limb' anchor as shown in Fig.1, the preferred ar arrangement under t'he shortening of the set ting-member. v

In applying and using the device, reference is now made to Fig. 4. The initial separation of the anchor members having been determined and the necessary adjustments made bers (Sand 8, the anchor member 1 is fixedly by means of the upper and lower tie-memincorporated in. a cast 13 applied to the broken-limb 14, while the anchor member 2 is fixed in a cast 15 on the sound-limb 16;

V Thereupon, the turn-buckle -nut 12 with the desired effect 5 turned in a direction to lengthen the settingmember 11 by the separation of its aligned sections, in case the form of Fig. 1 be used, or by the shortening of said member if the form of Fig. 3 be adopted, so that the general frame changes shape as indicated by the dotted linesinsaid figures, with the effect of ap* plying stretching tension to the broken limb,

with counter resistance from the sound limb.

I claim 1. An appliance for reducing fractures, comprising a pair of anchor members adapted for fixation, one to the broken limb 'andthe other to the sound limb; a pair of tie-members pivotally connecting said anchor me'mbers above and below; and an axially adjust-- able setting-member pivotally connected with the upper end of one'anchor member and with the lower end vof the other anchor member;

2; appliance for reducing fractures,

comprisingapair of anchor members adapted for fixation, one to the broken hmb and the other to the sound limb a pair of axially adjustable tie-members pivotally connecting, said anchor members above and below; and: an axially adjustable setting-member pivot ally connected with the upper end ofone anchor member and with the lower end of the other anchor member.

3. An appliance for reducing fractures,

comprising a pair of anchor members-adaptedforfixation, one tothe broken limb and'the other to the sound limb; a pair of tie-members I pivotally connecting said anchor mem-- bers above and below; and an axially adjustable setting-member pivotally connected with the upper end ofth'e anchor member to be fixedto the sound limb and with the lower end of the anchor member, to be fixed: to the broken limb.

4:. An appliance for reducing fractures,-

comprising a pair of anchor members adapted for fixation, one to the broken limb andtheother to the sound limb; a pair of axially adjustable tie-members pivotally connecting said anchor members above and below; andan axially adjustable setting-member pivotally connected with the upper end of the-an chor member to be fixed to the sound'limb and with the lower end of the-anchor memher to be fixed to the broken limb.-

In testimony whereof I have signed my name to this specification.

PETER B. MOORAKEN.
