ADJUSTABLE SURGICAL FINGER SPLINT Filed 001;. 9, 1951 33 m 2 2o "618m ADRIAN D. 'BAER Zhwentor Gttomegs Patented July 28, @953 UNITED sTATEs PATENT OFFICE Claims.

My invention relates v more particularly, to an adjustable surgical finger splint. Briefly, the splint includes two splint members having their inner ends juxtaposed and forming an extensible splint to fit different length fingers. At one end of the splint is a crutch end disposed ,to' bear on the fleshy portion of the palm adjacent the knuckle of an injured finger positioned on the splint. The other end of the splint has adjustable means for securing tension means and adjusting traction on the injured finger.

In forming a splint for a finger, an important object is to provide adequate securing means for the end of the splint near the knuckle so that the digit may be maintained in longitudinal traction while the broken phalanx heals. Convenient means should be provided for applying and adjusting the traction. At the same time, the splint should be formed with consideration for the comfort of the patient and for the usefulness of the hand. As fingers vary in length, a splint should be adjustable so that it may be used for digits of various lengths. T

The objects of my invention include, therefore, to provide a finger splint with special provision for adequate securing of the end of the splint near the knuckle, todevise means for to surgical splints, and,

conveniently applying and adjusting the trac- 7 tion, to provide maximum protection of the injured digit while'avoiding unnecessary encumbrance so that the hand may be useful, to devise which will be comfortable to the patient, and to 7 provide a splint which is adjustable for various lengths of fingers.

. Further objects, advantages and capabilities will be apparent from the description and disclosure in the drawings, or may be comprehended or are inherent in the device.

In the drawings: Figure 1 is a perspective view of a splint which is a specific embodiment of my invention;

Figure 2 is aside view of the splint, partly in section, and shown as it appears in use on an injured digit; j V

Figure 3 is a side view, of part ofthe assembly as it would appear when used as a protective rather than a traction devise; 1 I Figure 4 is a side view, partly in section and enlarged, of the traveler and screw eye portion of the device; V g

Figure 5 is a cross-sectional view takenon line 5 5 of Figure 4; and 1 Figure 6 is a. view, partly in section and enla s ta e o l p re;

The splint has a first and a second splint member, 10 and I2 respectively. These are preferably made of somewhat malleable material so that the splint can be shaped to fit a particular hand if necessary. At the same time, the material must be rigid enough to withstand the forces applied thereon in placing a finger in traction. The inner ends of the splint members are juxtaposed and are slidable longitudinally of each other, thereby forming an extensible unit to accommodate various lengths of fingers.

Means of securing the splint members together include openings in first splint member [0 and square headed bolts l4 and I6. Splint member 12 has a slot H3 in which the bolts are positioned and slotted nuts 20, 22 complete the assembly.

As shown in Figure 1, the upper face of splint member H! is concave transversely to accommodate the shape of the finger positioned thereon. The finger is taped to the splint as partially shown at in Figure 2 and this is a primary means of securing the splint to the finger including the prevention of longitudinal movement. In preventing such longitudinal movement it acts in two ways. in directly securing the finger to the splint and in positioning curved crutch end 32 in position to act as securing means. Crutch end 32 bears on the fleshy portion of the palm near the juncture of the injured digit and the metacarpus, and the crutch end is designed to closely fit this portion. This crutch end should be, distinguished from a splint end resting on the center of the palm because such a palm rest requires that the finger be maintained at an angle to the surface of the palm if the rest is to maintain its function. With the present device, the finger can be substantially straightened without dislodging. cruch end 32..

7 and runs across the first splint member [0. It

will be seen that means has been provided for adequately securing the splint while providing for minimum encumbrance of the hand and with due consideration to comfort.

The outer end of second splint member I2 has a boss 50 disposed in line with the injured digit. Boss 50 is of large size and will protect the finger even if the splint is used only as a protective device, rather than a traction device, as shown Figure 3. When the splint is used for longitudinal traction, boss 50 provides, in addition to its protective function, a bearing for traveler 52. The major portion of traveler 52 is rod shaped and has threads 54. Nut 55, preferably having a knurled surface, is positioned on the outer end of traveler 52 and provides means for making fine adjustments of the position of traveler 52, and consequently of the amount of traction on the finger. Traveler 52 is held from rotation, as nut 56 is tightened, by a straight edge 58 of flange E abutting the adjacent surface of splint member I2.

Traveler 52 has a screw eye I'D positioned in a threaded bore. the finger by means of a rubber band ll taped to the finger, as shown at E2 in Figure 2, and hooked on screw eye it.

In placing the finger on the splint, first and second splint members id, l2 are adjusted to the length of the finger and secured in their relative position by tightening nuts 2t and 22. Then the crutch end 32 is positioned firmly in place and secured by tape. Screw eye ll! is disposed generally in the position it is to occupy in traction; and then rubber band i! is hooked on the screw eye. It may be found that more or less pressure is required and this may be closely adjusted by means of traveler 52 and nut 5% without appreciably disturbing the positioning of screw eye It and band ll. On later examination of the finger during convalescence it may be desired to change the tension on the band and this may be conveniently accomplished by means of traveler 52. By these means, the traction applying members may be conveniently adjusted to the finger in first roughly approximating the desirable positioning and in later making an exact application of traction. Because the traveler does not rotate, the positioning of the screw eye is not disturbed during final adjustment and the splint should be successfully applied in one operation. This is to be contrasted with other systems where the splint is often applied several times'before a satisfactory adjustment, is achieved or where the doctor has to be satisfied with a general approximation of the desired degree of traction. The present adjustable finger splint is both time conserving and sparing of discomfort to the patient.

It is believed that it will be clearly apparent from the above, description and the disclosure in the drawings that the invention comprehends a novel construction of an adjustable surgical finger splint.
