SURGICAL SPLINT.

Specification of Letters Patent.

Patented July 11), 1917.

Application filed October 16, 1916. Serial No. 125,832.

To all whom it may concern:

Be it known that I, JOSEPH L. NYLANDER, a citizen of the United States, residing at Seattle, in the county of King and State of lVashington, have invented certain new and useful Improvements in Surgical Splints; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

This invention relates to surgical splints for supporting broken limbs; and it consists of a contractible casing for the limb constructed as hereinafter fully described and claimed.

In the drawings, Figure 1 is a side view 0 a splint constructed according to this invention. Fig. 2 is an end view of the splint, showing the limb in cross'section.

The body of the splint is formed of two curved plates 2 of aluminum or other equivalent material which is very light, flexible and resilient, but yet sufliciently stiff to hold the broken parts of the bone in position, and which is translucent to the X rays to a greater extent than human bone.

These two curved plates form a tubular casing adapted to fit around the broken portions of the limb, and they have longitudinal stiffening bars 3 at their edges and at suitable intermediate intervals. These bars are also 'formed of aluminum, and they may be secured to the plates 2 by rivets 1 or in any other convenient way.

Screws 5 are pivoted by pins 6 t0 lugs 7 on the edges of one plate, and the other plate has lugs 8 secured to it. The screws are slidable loosely in holes in the lugs 8, and they have thumb-nuts 9 screwed on them. These nuts enable the plates to be contracted upon the limb. The limb 10 has a suitable bandage 12 wound around it. This bandage is of soft material, such as textile goods, and it is relatively thin. The sections of the splint are contracted by the screws upon the band age so as to hold the parts 14 of the bone in a position to unite, and the sections are contracted from time to time as the flesh of the limb shrinks or as swelling in it goes down.

With plaster casts, as ordinarily used, the casts become loose when the swelling of the flesh goes down, and the broken bones some times fail to unite in consequence of not being held satisfactorily in position.

The translucence of the aluminum to the X rays enables photographs of the bone to be taken as often as desirable, so that the exact position of the broken portions of the bone can be ascertained.

What I claim is:

1. A surgical splint, comprising two curved plates of thin and flexible sheet metal, longitudinal stiffening bars secured to the adjacent edges of the said plates and at intermediate points, and fastening devices secured to the said edges.

2. A surgical splint, comprising two curved plates of thin and flexible sheet aluminum which is more translucent to the X rays than a human bone, longitudinal stiflening bars secured to the adjacent edges of the sald plates and at intermediate points, and fastening devices secured to the said edges.

In testimony whereof I have aiflxed my signature.

JOSEPH L. NYLANDER.
