破壊に至らしめる。However, in general, in the case of a surgical procedure using bone replacement, bone reacts sensitively to the replacement material, the properties of the bone itself change, and the replacement material is subjected to a repeated load for a long period of time. However, the fracture strength due to fatigue becomes a problem. In the above-described prosthesis A using cement C, the end faces of the bones B abut at the step portions D, and a load is intensively applied. As a result, the prosthesis A is liable to be broken. The concentrated load at the corner weakens the bone or causes bone resorption, causing the cement C used for bonding to peel or break, and as a result, the phenomenon that the fixation to the bone cannot be maintained has occurred. Moreover, the metal, ceramic, and the like forming the prosthesis have extremely high rigidity as compared with bone, and the rigidity changes abruptly at the joint, and hardly follows bone deformation. As a result, displacement easily occurs between the bone and the cement, and between the cement and the insertion shaft portion, which causes rattling. Once such rattling occurs, the rattling of the prosthesis becomes larger and more likely to cause bone destruction.

体を成した構造である。FIG. 1 shows a state in which a metal prosthesis P is attached to a bone. Reference numeral 1 denotes a shaft for inserting the bone into the medullary cavity of the bone. 2 is provided with an auxiliary plate 3 facing the shaft portion 1 at a desired interval.
That is, the shaft portion 1, the base end portion 2, and the auxiliary plate 3 are integrally formed.

基端部２が骨Ｂの端部に固定できる構造となっている。A through-hole 4 and a bottomed bolt hole 5 are coaxially formed in a portion corresponding to the shaft portion 1 and the auxiliary plate 3, and a fixing bolt 6 is inserted through the through-hole 4 of the auxiliary plate 3. And screw it into the bottomed bolt hole 5 of the shaft 1. Thereby, the biological prosthesis P is firmly fixed to the bone, and as a result,
The base 2 has a structure that can be fixed to the end of the bone B.

Using a dedicated instrument with the through hole 4 as a guide, a prepared hole is made in the bone. Then, in this state, the fixing bolt 6 is inserted into the through hole 4 of the auxiliary plate 3 and screwed into the bottomed bolt hole 5 of the shaft portion 1.

体内での安全性が非常に高い。The thus constructed living body prosthesis has a rattling and rotation without the use of cement due to the force by which the shaft portion 1 and the auxiliary plate 3 hold the bone B and the fixing by the fixing bolts 6. No strong fixation is possible. A groove 3a is provided at the base of the auxiliary plate 3 as shown in an enlarged manner in FIG.
It may have a spring property. Further, by providing a small gap between the bone B and the base end 2 by positioning, it is possible to prevent a problem that the end of the bone B is weakened by stress concentration and bone resorption occurs. Further, the living body prosthesis P is characterized in that a bolt fixing hole provided in the shaft portion 1 has a bottom (bottomed bolt hole 5). By doing so, the stress applied to the end of the bolt hole can be greatly reduced, the mechanical strength is large, and it is hard to break, so that the safety in a living body is very high.

ある。It is to be noted that F is a condition under the condition of a static load of 75 kgf.
When EM analysis was performed, the stress applied to the end of the hole when the bolt hole of the shaft portion 1 was a bottomed hole was 71.84 Kgf.
/ Mm 2 and 94.58 Kgf /
It was confirmed that it was much smaller than mm 2 . In addition,
In order to sufficiently reduce the stress, the thickness t of the bottomed bolt hole 5 in the shaft portion 1 is preferably 2 mm or more.
On the other hand, the depth d of the bottomed bolt hole 5 is preferably 5 mm or more. This is because if the depth is less than 5 mm, the screwing force of the fixing bolt 6 may be insufficient.

Good. However, at this time, it is important that the mechanical strength of the shaft portion 1 and the auxiliary plate 3 is not unnecessarily deteriorated. In other words, if a treatment at a high temperature is performed, the strength of the base material is deteriorated. Therefore, it is desirable not to perform the above-described thermal spraying on the joint portion between the shaft portion 1 and the base end portion 2 in the auxiliary plate 3.
