〔産業上の利用分野〕
本発明は、人体に適用する人工股関節、人工肩関節など
の人工関節に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to artificial joints such as an artificial hip joint and an artificial shoulder joint applied to the human body.
従来から用いられている例えば第４図（イ）に示した如
き人工関節は寛骨などに埋入したソケット（不図示）、
該ソケットに対し回動自在に嵌合する摺動部（球面形状
）Ｋを先端に備えたステムＳとで構成されている。Conventionally used artificial joints, such as the one shown in FIG.
It is composed of a stem S having a sliding portion (spherical shape) K at its tip that rotatably fits into the socket.
このうちステムＳはステンレス綱、コバルトクロム合金
などの金属から成り、長管骨Ａの骨髄腔Ｂ中に挿入し、
ステムＳと長管骨Ａとの間にセメントＣを介在させて固
定し、一方のソケットも同様にセメントを用いて固定す
るのが一般的である。Of these, the stem S is made of metal such as stainless steel or cobalt chromium alloy, and is inserted into the medullary cavity B of the long bone A.
Generally, the stem S and the long bone A are fixed by interposing a cement C, and one socket is similarly fixed using cement.
しかし、セメントＣでの固定は初期においては十分に強
いものでも長期においては緩みの生じるものがあり、こ
の緩みの発生が人工関節のもつ主要な問題点となってい
る。However, even if fixation with cement C is sufficiently strong in the initial stage, it may loosen over a long period of time, and this loosening is a major problem with artificial joints.
緩みの原因としては、
■長管骨Ａ１セメントＣ及びステムＳのヤング率の違い
によって、荷重を受けた場合の変形量が異なりこれら３
つの材質間の接合面に剪断力が発生すること
■ステムＳと長管骨Ａの骨髄腔Ｂとのデザインの不整合
によってセメントＣの厚みが不均一となり、薄いセメン
ト層の破壊や、伝達荷重の増加が発生すること
■セメントＣのもつ重合熱やモノマーの流出によって骨
の破壊が進むこと
などが上げられている。The causes of loosening are: ■The amount of deformation when loaded is different due to the difference in Young's modulus of long bone A1 cement C and stem S.
A shearing force is generated at the interface between the two materials. - Due to the mismatch in design between the stem S and the medullary canal B of the long bone A, the thickness of the cement C becomes uneven, causing destruction of the thin cement layer and the transmitted load. It is said that bone destruction progresses due to the polymerization heat of cement C and the outflow of monomers.
これらの原因を除去するための対策として■ヤング率が
骨と近いチタン合金の選択■セメント層を均一にし、セ
メント圧を高めるため適正なステムデザインの考案
■セメントＣを使用せず骨髄腔ＢヘステムＳを打込むこ
とによって固定するセメントレスステムの考案などがな
されている。Measures to eliminate these causes include: - Selection of a titanium alloy with a Young's modulus close to that of bone. - Development of an appropriate stem design to make the cement layer uniform and increase cement pressure. - Creation of a medullary canal B hestem without using cement C. Cementless stems that are fixed by driving S have been devised.
上記長管骨ＡとセメントＣ、ステムＳとの緩みを解決す
る有力な手段としてステムＳのデザイン（形状）が第一
にあげられるが、従来のステムＳでは、特に長管骨Ａ管
端部付近の骨髄腔Ｂが広がっている部分でのステムデザ
インの改良の余地を残している。The design (shape) of the stem S is the first effective means of resolving the loosening between the long bone A, the cement C, and the stem S. There is still room for improvement in the stem design in the area where the nearby medullary cavity B widens.
即ち、第４図（ハ）に示すように、従来のステ％１、長
管骨Ａの前幹部付近の骨髄腔Ｂには、円錐状のステム滲
遠位部Ｓ２を多種類用意することによってフィツトする
ことが可能であるが、第４図（ロ）に示すように管端部
付近の複雑な骨髄腔Ｂには、従来の単純なステム近位部
Ｓ１ではフィツトには限界がある。That is, as shown in FIG. 4(c), in the conventional stem %1, by preparing many types of conical stem extrusion distal parts S2 in the medullary cavity B near the anterior trunk of the long bone A. However, as shown in FIG. 4(b), there is a limit to how well the conventional simple stem proximal portion S1 can fit into the complicated medullary cavity B near the tube end.
本発明は管端部でもステムが骨と十分にフィツトし、こ
れによりセメントレスでステムの固定力を高め、また、
セメントを使用する場合でも、骨への荷重伝達を小さく
することで、セメントの破壊を未然に防ぎ、ステムの緩
みを防止すべく人工関節のステムに対し、両側面に突起
を有し、該突起が骨髄腔壁に当接し安定固定を図るため
の挿入体を着脱自在に装着する。In the present invention, the stem fits well with the bone even at the tube end, thereby increasing the fixation force of the stem without cement.
Even when cement is used, the artificial joint stem has protrusions on both sides to prevent the cement from breaking and to prevent the stem from loosening by reducing the load transmitted to the bone. An insert is removably attached to the bone to ensure stable fixation by contacting the wall of the medullary cavity.
かかるステムからなる人工関節の作用として、■十分な
支持力の得られるセメントレス固定が可能となる。The function of an artificial joint made of such a stem is: (1) Cementless fixation with sufficient supporting force is possible.
■セメントの持つ欠点である重合熱やモノマーの流出を
防ぐことができる。■Can prevent polymerization heat and monomer outflow, which are disadvantages of cement.
■骨との接触面積を大きくすることにより、骨への伝達
荷重を減し、骨の吸収、変形等を防止する。■By increasing the contact area with the bone, the load transmitted to the bone is reduced and bone resorption, deformation, etc. are prevented.
■セメントを使用する場合でも、セメントの接触面を増
大させることができ、その結果、セメントとステム間の
固定力が高められる。■Even when cement is used, the contact surface of the cement can be increased, and as a result, the fixing force between the cement and the stem is increased.

Reference numeral 1 denotes a stem for insertion and fixation into the femur, and a horizontal hole 1a is bored in the upper part of this stem 1. This horizontal hole 1a has a tapered shape with a tapered wall surface 1b, and has a projection 2.
The insert body 2 with a formed on both sides is inserted and fixed, and as shown in FIG. It is fixed to the stem 1 by abutting the tapered surface 2b. In this way, the insert 2 to be installed in the horizontal hole 1a of the stem 1 is prepared in advance with a large number of protrusions 2a of different sizes and shapes. An insert 2 is selected and used which can abut the wall on both sides and be stably fixed.

When inserted into the medullary cavity of the humerus, the insert 20 is stably fixed with the protrusion 2a in contact with the retaining wall. In this case as well, an insert 20 having a protrusion 20a of an optimal size is selected depending on the size of the medullary canal of the humerus, and the insert 20 attached to the lateral hole 10a is used.
