The present invention relates to bone fixing nails, and more particularly to bone fixing nails used for fractures or cut sites in living bones caused by bone fractures.
In this case, fixing tools such as stainless steel plates, sutures, and alumina screws are often used, but if stainless steel plates are used, it is necessary to remove the fixing tools through surgery again. In the latter case, the implanted fixation device and the living body are in contact with each other through connective tissue, so they do not become integrated, and in some cases, a loosening force may occur, necessitating the removal of the fixation device in a reoperation). A situation arises. On the other hand, attempts have been made to coat the surface of the fixation device with a calcium phosphate compound to improve the compatibility between the fixation device, bone tissue, and living body, but the coated calcium phosphate compound does not remain in the body as it is. Due to dissolution, problems similar to those described above occur after a period of time. In addition, the bone may be fixed using stainless steel wire or surgical sutures, but in this case, as these substances are foreign to the living body, the living body may react to the foreign body, and the bone may be removed by re-surgery. There is a need to. Due to the above-mentioned problems, in actual clinical practice, it is unavoidable to leave the tissue as it is, or to cover it with periosteum near the rupture or cut, in areas where mechanically large forces are not applied. However, if left as is, the bone often moves from its original location and joins together, and although the movement can be suppressed a little by wrapping it with periosteum, it is still almost the same as its original location. They rarely join in shape, resulting in a shape that differs from the original living tissue. Furthermore, since the broken bone is not sufficiently fixed at the cut site, there is a problem in that it takes time for the bone tissue to recover. In view of the current situation, the present inventors have conducted various studies in an effort to obtain a bone fixation device that does not have these drawbacks, and as a result, have completed the present invention. That is, according to the present invention, it is an object of the present invention to provide a bone fixing nail with excellent biocompatibility that does not require removal through reoperation and is ultimately integrated with bone tissue.The bone of the present invention The fixing nail is made of a calcium phosphate compound, has a compressive strength of 500 kg'/cn1 or more, and is characterized by being integrated with living bone.The present invention will be described in detail below.For bone fixation of the present invention Calcium phosphate compounds used for nails include tricalcium phosphate, heptadrochin apatite,
Compounds in which part of the hydroxyl groups of tetracalcium phosphate, oxyapatite, calcium pyrophosphate, fluoroapatite, and bitroxyapatite are replaced with fluorine ions, and mixtures thereof, which are produced quickly and integrate quickly with living bone tissue. Moreover, examples of the material having excellent biocompatibility include one or a mixture of two or more selected from tricalcium phosphate, hydroquinapatite, fluoroapatite, and tetracalcium phosphate. Among them, hydroxyapatite can be said to be the most preferable because it has the fastest new bone formation rate. The calcium phosphate compound used in the present invention may be artificially synthesized by a known production method, or may be a natural compound obtained from bones or the like. The method of manufacturing the bone fixation nail of the present invention involves preparing a sintered body of a calcium phosphate compound in advance, and processing the sintered body or molding it into a desired shape in advance, taking into account shrinkage during firing. It is also possible to create it using a dry rubber press lathe or the like and then fire it. The compressive strength of the bone fixation nail used in the present invention is 500

[Cannot be used because it is not possible to fix the cut part.] The upper limit is not particularly limited, but due to the nature of the calcium phosphate compound, the upper limit is practically 1o, oo. It is about kg/ctZ. As will be explained with reference to FIGS. 1 and 2, the shape of the bone fixing nail of the present invention is a prism 10 or a cylinder 20, and at least the tip 11 thereof is tapered as shown in the figure, and the tip has an end surface. It is preferable to have 12. In the case of such a shape, a hole having a size smaller than the dimension l of the cross section S of the bone fixation nail 10 is made at a predetermined fixation location of the living bone, and the tapered tip 11 is driven into the hole. This is preferable because it can be firmly fixed, it does not enter the hole more than necessary, and the force on the end face 12ζζ is concentrated during driving, making it easier to drive. Furthermore, if no taper is provided, the bone fixing nail may break because force is required for driving. As shown in Fig. 3, a polygonal prism 30
The ratio of the tapered tip 11 may be increased, or the truncated conical shape 4 may be made larger as shown in FIGS. 4 and 5.
0 or a truncated pyramid shape 50, and the tapered portion 13 may extend not only to the tip but also to the entire side surface. When the end face] 2 is provided, it is preferable because there is no risk of irritation to living tissue and carcinogenesis compared to the case where the end face is sharp. Furthermore, as shown in FIG. 6, it may be a shape 60 that is a combination of a cylinder and a truncated pyramid, or a stacked shape such as a combination of a prism and a truncated cone (70 in FIG. 7) is conceivable. 8th
As shown in the figure, only one side of the distal end portion 11 of the bone fixing nail 80 may be tapered. Bone fixation nails 10.20.30.40.50.60.7
The cross-sectional area S of 0.80 is preferably 4IIIm2 or more. If the cross section is 4 squares or less, the strength of the nail will not be sufficient when driving for fixing, and breakage may occur. The area of the end surface 12 of the tapered part 11 of the fixing nail is 1 mm.
It is preferable that the diameter is 9 mm or less.If the diameter is less than 2, breakage may occur at the taper part 11 during driving, and if the diameter is 9 mm or more, the end face 1 may be broken before fixing.
It is necessary to drill a hole slightly larger than 2 and drive it in, but since the hole becomes larger, there is a risk of re-fracture at that site. The present invention will be specifically described below with reference to Examples. [Example 1] Four parts of the femur and skull of a domestic rabbit were cut out to a size of 5 mm, and the resulting bone fragments were made into cylinders made of calcium phosphate, hydroxyapatite, and tetracarunum phosphate and having tapered end surfaces 12. 20, the cross section S of the cylinder has an area of 4 mm2, an end face 12 has an area of 1 mm2, a tip end 11 has a height of 3 mm, and the height is 10 mm. After fixing at three locations with the bone fixing nails 20, The part unnecessary for fixation was cut off, and the remaining bone fragment was returned to its original position and sutured with periosteum. The compressive strength of each sample used as a nail for bone fixation was 5X 5
When measured using a universal testing machine (manufactured by Instron) using X5 wind samples, each was 1800.2500.1.
000 kg/c+++. When the rabbit was sacrificed 4 weeks after the surgery and the fixation site was observed, it was found that when no fixation tool was used, the bone fragments protruded obliquely from the defect and joined to the bone. On the other hand, fixation was performed using a cylinder 20 made of tricalcium phosphate, hydroxyapatite, and tetracalcium phosphate and having a tapered end surface. was firmly fixed. When these champions were cut along the surface containing the fixing nails and the interface between the framework acid and the fixing nails was observed, no foreign body reaction was observed in either case. It was observed that the bones were directly connected by new bone. [Example 2] A truncated quadrangular pyramid 50 made of hydroxyapatite and having a tapered end surface 12 has an area of cross section S of 2.
.. 4, lr, 25.36mm2, area of end face 12 is 05
.. 1.4.9.251W12 with a height of 5III11, and a square prism 10 with a cross-sectional area of 2.4.10.25.36 without tapering.
Drill a hole slightly smaller than the cross section S in the cow's femur bone with mm2 and height of 5 m + n, drive 5 holes into each hole, and check the number of holes rA'I that can be driven (the number of holes that did not break). Ta. Furthermore, the compressive strength of hydroxyapatite was measured in the same manner as in Example 1. These results are shown in Table 1. [Example 3] A rectangular prism 10 made of tight hydroquine having various compressive strengths and having a tapered end face 12. The area force of the cross section S of the rectangular prism is τ9m1112, and the area of the end face 12 is 4 mm2, Height of tip 1: 4mm
The number of holes that could be driven into a cow's femur was determined by driving five of each type with a height of 10 mm into a 7-diameter hole drilled in a cow's femur. Compressive strength (ζ strength) was also measured in the same manner as in Example 1. These results are shown in Table 2. [Comparative Example 1] The same method as in Example 1 was performed on the femur and tibia of a domestic rabbit (a defect of the same size was created with a trowel, the resulting bone fragments were fixed with an alumina screw and a stainless steel screw, and After a week had passed, the fixed site was taken out and cut along the plane containing the fixation tool to create a tissue specimen.As a result, when stainless steel screws were used, foreign giant cells were found at the interface between the stainless steel and the bone tissue. On the other hand, when alumina screws were used, although a strong foreign body reaction like stainless steel was not observed, there was a strong foreign body reaction at the interface between alumina and bone tissue. There was no finding that connective tissue was present and that alumina and bone tissue were directly connected.
