FRACTURE PLATE Feb. 5, 1957 Filed May 17, 1955 INVENTOR I Paul 5.17% Zzuuf United States Patent 0 FRACTURE PLATE Paul B. Haggland, Fairbanks, Territory of Alaska Application May 17, 1955, Serial No. 508,889 6 Claims. (Cl. 128-92) This invention relates to surgical appliances, and in particular to fracture plates adapted to engage and stabilize fractured bone ends.

A principal object of the invention is to provide an improved fracture plate of novel shape and configuration, adapted for multi-plane fixation of a bone.

Another object of the invention is to provide a fracture plate adapted to effectively engage and stabilize secondary bone fragments. A related object is the provision of a fracture plate configured to position the bone screws used therewith in offset or spaced relationship, longitudinally, laterally and angularly.

Still another object is to provide a fracture plate ideally suited to coapt bone grafts at the fracture site. Further objects will be in part evident and in part pointed out hereinafter.

The invention and the novel features thereof may best be made clear from the following description and the accompanying drawings in which:

Figure l is a plan view of a preferred embodiment of the invention, applied to a fractured bone;

Figure 2 is a sectional view taken on the line 22 of Figure 1;

Figure 3 is a sectional view taken on the line 3--3 of Figure l, and

Figure 4 is a sectional view taken on the line 4-4 of Figure 1.

Referring to the drawings in detail, Figure 1 illustrates a femur shaft 10, fractured at 12. The fracture plate comprises a sheet 14, constructed of stainless steel or similar corrosion-resistant material, generally diamond shaped in form and centrally branched into side bands 16 and 18, which enclose a central opening 20. The central opening, preferably, is also diamond shaped, its sides being parallel to the outer edges of the sheet, whereby the side bands are of uniform width throughout their length. To rigidify the structure, the sides of the sheet and opening may be outwardly ribbed or beaded, as at 22.

The sheet 14 is curved cylindrically about a longitudinal axis parallel to it but spaced somewhat therefrom, whereby it is adapted to fit closely about and partially enclose the bone 10, as best illustrated in Figures 2 to 4. At its widest central point, the device may extend about, for example, one third of the circumference of the bone, of subtend an arc of 120. The inner surface of the sheet is preferably smooth, as shown.

The sheet 14 is provided with a plurality of longitudinally extended screw receiving slots 24, spaced more or less evenly along its length. As an outstanding feature of the invention, each slot is also spaced laterally with respect to adjacent slots, being arranged preferably in two rows coinciding at their ends but diverging therebetween in substantial parallelism to the sheet sides. The slot rows, as will be apparent, follow the side bands 16 and 18, and the overall effect is a unique, staggered slot pattern.

In applying the device, the bone ends must be manipu- 2,780,223 Patented Feb. 5, 1957 lated into apposition, and an incision made to the bone. The plate may then be positioned as shown in Figure l, with its center coinciding substantially with the fracture, whereby the device extends an equal distance in both directions therefrom. It will be noted that the device can be placed easily, since it isnarrow at both ends and widest in the middle, where the incision can be retracted most easily and to the greatest extent; I v

A bone screw 26 may next be inserted through eacli slot 24 into the bone, each screw being directed through the central axis of the bone, or in direction generally normal to the sheet portion surrounding the involved slot. By reason of the slot pattern, each screw is angularly offset with respect to adjacent screws, whereby the bone ends are transfixed in a plurality of angularly diverse planes. This is illustrated in Figures 2, 3 and 4, and it will be seen that the side bands 16 and 18 are disposed in planes substantially at right angles to each other. This is highly advantageous since any secondary fragments present are likely to be engaged by one or more screws. Any tendency of the bone ends to rotate axially relative to each other is precluded, and a large number of screws may be utilized without danger of cracking or splitting the bone. The screws being offset longitudinal, ly, there is no possibility of conflict in insertion.

The cylindrical curvature of the device and its wide coverage at the fracture site adapt it to coapt-bone grafts. The curvature also contributes to stiffness, and cooperaes with the beads 22 to resist longitudinal bending. The curvature may be altered upon application to fit bones of different diameters, or the pull of the screws 26 may be relied on to conform the curvature to the bone.

The central opening 20, as will be evident, may be oval rather than diamond shaped, or otherwise shaped or omitted altogether. By way of specific example, the fracture plate may be 8" in overall length, and subtend an are at its center of 120. The slots 24 may be .175" x .5", and the sheet 14 may be .10 thick and .15" thick through the beads 22. The diameter of the cylinder of curvature may be 1.25".

It will thus be seen that there has been provided by this invention a structure in which the various objects hereinbefore set forth, together with many practical advantages, are successfully achieved. As various possible embodiments may be made of the mechanical features of the above invention, all without departing from the scope thereof, it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawings is to be interpreted as illustrative, and not in a limiting sense.

I claim:

1. A fracture plate comprising an enlarged central portion and narrow ends joined thereto by longitudinally extending portions decreasing in width from the central portion to said ends, said plate being curved cylindrically about a longitudinal axis parallel to but spaced from said plate, whereby the plate is adapted to fit about and partially enclose a bone, and a plurality of longitudinally and transversely spaced openings in said plate, said openings being arranged in said plate to define two rows diverging from each of said ends toward said central portion.

2. A fracture plate as defined in claim 1 wherein the rows coincide at the ends of the plate.

3. A fracture plate comprising a diamond shaped sheet curved cylindrically about a longitudinal axis parallel to but spaced from said sheet, whereby the sheet is adapted to fit about and partially enclose a bone, and a plurality of longitudinally and transversely spaced screw openings in said sheet, said openings being arranged in rows defining a diamond outline generally paralleling the shape of the sheet.

4. A fracture plate comprising a diamond shaped,

centrally branched metal sheet curved cylindrically about a longitudinal axis parallel to but spaced from said sheet, whereby the sheet is adapted to fit about and partially enclose a bone, and a plurality of longitudinally extended screw slots in said sheet, said slots being spaced from each other in both longitudinal and transverse directions and defining a diamond outline generally parallel to and substantially coextensive with the outer sides of said sheet.

5. A fracture plate comprising a diamond shaped, centrally branched metal sheet curved cylindrically about a longitudinal axis parallel to but spaced from said sheet, whereby the sheet is adapted to fit about and partially enclose a bone, and a plurality of longitudinally extended screw slots in said sheet, said slots being longil5 tudinally spaced from each other and arranged in rows paralleling the sides of the sheet.

6. A fracture plate as defined in claim 5, wherein said sheet is outwardly beaded along its sides to rigidity the 5 structure.
