Application filed August 4, 1921. Serial No. 489,833.
(GRANTED UNDER- TI-IE PRDVISIONS 035 THE ACT OF MARCH 3, 1921, 41 STAT. L, 1313.)
vented certain new and useful Improvements in Splints (for which lhave filed an application in Great Britain Oct. 2, 1915, Patent No. 13,97 6), of which the following is a specification.
This invention refers to splints employed in what I term the ambulatory treatment of injuries or diseases of the lower limbs, applicable for instance for the treatment of fracture, shot wounds, tubercular and other diseases of the joints, the office of such splints being to take the weight of the body off the leg and in addition be utilized to produce extension between the surfaces of the condyles in joint diseases, or in the case of a fracture to keep the fragments in apposition. a
The appliance which I have heretofore employed broadly consists of a bucketshaped casing which embraces the upper part of the thigh and buttock and upon or within which the weight of the body can be supported, While proceeding downwards from each side of the casing, on opposite sides thereof, is a rigid rod, a foot plate being fixed at the lower ends of the said rods. In some cases the rods may be jointed, having say a knee or ankle joint. To thes'e rods the edges of'a flexible support of suitable material such as canvas are adjust-ably fixed to serve as a support for the back of the leg, while a support of similar material is also fixed to the rods to pass over the knee.
In such a splint the ankle of the patient is fitted with an ankle gaiter of flexible material, so that when the whole appliance is in position and the patients weight is supported in the upper straps from the ankle gaiter pass beneath the foot plate to retain the patients foot in I position, which straps can be adjusted until the requisite extension has been obtained, should such extension. be desirable.
In such apparatus it is of the utmost importance that the weight of the patient should be wholly sustainedby the bucketshaped thigh casing without causing injury, pain or inconvenience, and this portion of the appliance I so construct that there is no pressure at all on the perineum or pubic bucket-shaped casing,
"curative process, movement can be allowed almost immediately which not only permits of exercise and prevents stagnation of the blood supply, but in fact increases it. Now
'in treating injuries to the lower limbs particularly of wounded on the field, the employment of such apparatus as above outlined would be of incalculable benefit 1f 1t was rendered capable of immediate and ready application, and was adjustable to suit any person to whom it might be desirable to apply it to and the present invention is directed to meeting these-requirements.
The present invention therefore particularly refers to so constructing such a splint or appliance that it can be applied to any patient without difficulty and without lifting or raising the limb or the body of the patient, and thereby to render the appliance such that it can be employed for injuries sustaiped to the lower limbs during war and so applied even. on the field with the result of enabling the injured person to stand and even to walk a-reasonable distance without producing further complications or excessive pain. To this end, as hereafter described, the thigh casing or thigh bucket which is mainly constructed of rigid material preferably of metal, is divided in a vertical direction into two portions, one division being at the front of the thigh bucket and the other division at the rear, so that the inner portion of the thigh bucket can be slidden underneath the buttock, this inner portion being formed so that the tuberosity of the ischium hears upon itsrear inner surface. Then the outer portion can be brought towards this inner and rear portion and secured by straps, flexible flaps say of leather extending on the interior from the edges of the inner portion of the thigh bucket on to the inner surface of the outer portion of the portion l'can be passed thigh "bucket to cover the di'visions of the said bucket.
and outer portions of the thigh bucket easing is permitted by the springing apart or the downwardly extending rods.
I will further describe the in ention with reference to an example of construction shown on the accompanying drawings,
Whereon Fig; 1- shows the appliance in front 1Q elevation. Fig. 2 shows a side elevation of the appliance-shown in 1 1g. lathe appliance the thigh ,easing, gWlilllQlli) moving the The distancing of the inner patient. and In this adjustmentthe parts i and 3 of the thigh casing can be so brought to "ether as to lit the patient and permit his .weight and the strain of extension Where such is applied to be supported Without the said patientsuii ering much pain and inconvenlenee.

As aforesaid, therods 8iean beadjustable in length so as to distance the foot plate 9 from the thigh -casinges required, in such manner that the "the tuberosity of "the ischium and 3 is the "outer portion oft-he thigh casing.
