Abstract
ABSTRACT OF THE DISCLOSURE
A prosthetic nail for stabilizing fractures in the supracondylar area of the femur has in its plan configuration, an elongated flat shape and tapers over a substantial portion of its entire length from a relatively thick head section to a relatively thin tip section. The nail, in its elevational con-figuration, has a thin elongated midportion with two curved ends.
The larger head end has different inside and outside radii which cause it to be thickest at its extremity. The thinner tip end is shorter than the head end. The nail, in plain configuration, is about 279.4 mm. long. A hole for a lag screw is provided through the head end either at right angles to the elevational length of the nail or at a slight inward inclination thereto. The lag screw is threaded for retention in bone.

Description
107(~53 This invention relates to prosthetic nails implantable in bone.
Various elongated prosthetic nails of biocompatible metal are used for stabilizing fractures in bones. Such nails usually have a pointed tip end and a larger head secured to the bone in which they are implanted. An aim of this invention is to provide an efficient prosthetic nail for stabilizing fractures, particularly those in the supracondylar area of the femur.
According to the invention, there is provided a prosthetic nail of biocompatible metal implantable in bone for stabilizing fractures therein, particularly in the supracondylar area of the femur, wherein the nail is substantially flat and elongated and, in its plan configuration, tapers from a head to a rounded blunt tip approximately half the thickness of the head while, in its elevational configuration, the nail has a relative-ly thin tapered elongated midportion merging with a head end and a shorter tip end, both ends extending arcuately on the same side of the midportion, the inner and outer radii of the head end providing an enlarged thickness at the extremity thereof at which a retaining screw hole is axially disposed at an angle to the midportion in the elevational configuration.
More particularly, the prosthetic nail is made flat with substantially rectangular cross sections tapering from a larger (0.4 x 0.5 inch) head to a thin (0.2 x 0.05 inch~ blunt 5 rounded tip. The plan configuration of the nail tapers from a 1~7(~45:~
0.4 inch head to a 0.2 inch flat blunt ~ip. The elevational configuration has a relatively thin tapered midsection about 0.1 inch thick with two upwardly curved ends. The head end arcuately tapers out to a 0.5 inch thick head, which retains a lag screw for a length of about 2.5 inches. The tip has a radius of about 1.75 inches for a length of about one inch. The head is s~uared off around the lag screw hole which is disposed at a suitable angle for insertion in the bone such as perpendicular to the length of the nail or at a slightly smaller angle. The lag screw has threads and a length suitable for retention in the bone, for example, from about two to three inches.
In order that the invention may be fully understood, it will now be described in conjunction with the accompanying - drawings, in which:
Fig. 1 is a schematic view in elevation of a fractured supracondylar portion of the femur with a pair of prosthQtic nails embodying this invention inserted therein;
Fig. 2 is a view in elevation of one of the supra-condylar prosthetic nails shown in Fig. l;
Fig. 3 is a top plan view of the nail shown in Fig. 2;
Fig. 4 is a left end view in elevation of the nail shown in F ig . 2;
Fig. 5 is a partial view of a modificativn of the nail shown in Fig. 2;
Fig. 6 is a view in elevation of one of the lag screws shown in F ig . 1;

In Fig. 1 is shown a pair of supracondylar prosthetic nails 10 and 12A securing a T-shaped fracture designated by phantom lines 14 in the supracondylar area 16 of femur 18, which is partially shown in Fig. 1. Lag screw 20 secures the head of nails 10 and 12A to the supracondylar area of femur 18 and secures the split condylar portions of femur 18 together. Nails 10 and 12 are inserted with their longer ends disposed within the intra-medullary canal (not shown~ of femur 18.
Figs. 2-4 sho~ details of nail 10. An elevational con-figuration is shown in Fig. 2 with a substantially straight thin midportion 22 disposed between upwardly curved head end 24 and upwardly curved tip end 26. Midportion 22 tapers from a maximum thickness of about 0.5 inch (3.43 mm) to a minimum thickness of about 0.055 inch (1.40 mm). Head end 24 is formed, for example, by an outer radius of 3.25 inches (82.5 mm.) having a center of rotation disposed 3.115 inches (75.12 mm.) above midportion 22.
The inner radius of 2.25 inches (57.1 mm.) is tangent to the upper edge of midportion 22. Curved head portion extends about 2.5 inches (63.5 mm.) longitudinally from straight midportion 22.
Curved tip end 26 extends longitudinally about one inch from straight midportion 22, has parallel outer and upper radii of about 1.75 inch (44.4 mm.) forming an arc of about 30.
Fig. 3 shows the plan configuration with an overall length of about 11 inches ~279.4 mm.) and with a tapered inter-mediate portion I extending from about 4.25 inches (107.9 mm.) from a distance H about 1.25 inches (31.7 mm.) from the head of nail lOo Intermediate portion I tapers from about 0.410 inch (10.41 mm.) ad~acent the head of nail 10 to 0.224 inch (5.63 mm.).
The rest of the plan configuration of nail 10 has parallel sides.
Plan tip 28 has a rounded blunt end of full radius.
~ 07(~53 Head end 24 shown in Fig. 2 ha~ square top and side ends, 30 and 32, which contain hole 34 for receiving lag screw 20 shown in Figs 6-8. Hole 34 has its axis 36 disposed sub-stantially perpendicular to the length of nail 10. This is de-scribed as a lateral configuration for lag screw 20. Fig. 5shows what is described as a medial disposition for lag screw 20 by inclination of its axis 36A inwardly at an angle A of about 15~ relative to a perpendicular line 38A to the length of nail 12A. Lag screw holes 34 and 34A have upper counter-sunk ends 40 and 40A.
Supracondylar nails 10 and 12A may be used for stabiliz-ing various types of fractures of the supracondylar area of the femur either singly or in pairs. ~ails 10 and 12A and screws 20 are made of a biocompatible metal such as the cobalt-chromium alloy known as "Vitallium" a trademark of Howmedica, Inc., a corporation of Delaware, U. S. A.
The flat configuration of nails 10 and 12A helps pre-vent rotational displacement of the implanted nail. The gentle taper over substantially their entire length provides variable resistance to bending in different length portions in a manner similar to that obtained by a varying layer spring. The blunt dull tip end prevents the wall of the intramedullary canal from being pierced. Nails 10 and 12A are intended for use in stabiliz-ing fractures in the distal 1/3 area of the femur, for repairing various types of fractures such as T-shaped, condylar or any other fracture in the distal 1/3 area.
Figs. 6-8 show lag screw 20 which may vary in length, for example, from about two to three inches. It has a tapered flat head with a hexagonal socket. The tip is pointed and has 0 V-shaped sel~-tapping threads for firm bone engagement.
