Description

本発明は、橈骨の遠位端の骨折個所を固定する橈骨遠位端骨折用内固定器具に関するものである。   The present invention relates to an internal fixation device for fracture of the distal radius, which fixes a fracture site at the distal end of the radius.

関節部分は、皮質骨の厚みが薄く、かつ大きな力がかかることから、骨頭付近が骨折し易く、橈骨においても、遠位端において骨折することが多い。骨折治療の基本は、橈骨に限らず、骨折個所を強固に固定することであり、これには、ギブス固定や経皮ピンニングといった低侵襲施術、創外固定、観血整復、プレート固定といった方法がある。このうち、プレート固定、特に皮膚の内側でプレートを直接骨の表面にあてがう内固定は、仕掛けが骨折付近にとどまって大掛かりにならず、固定力も強いことから、最近ではよく用いられている。この点で、橈骨遠位端の骨折にもプレートによる内固定が推奨されるところである。   In the joint portion, since the cortical bone is thin and a large force is applied, the vicinity of the head of the joint is easily broken, and the rib is often broken at the distal end. The basics of fracture treatment are not limited to the ribs, but to firmly fix the fracture site. This includes minimally invasive procedures such as cast casting and percutaneous pinning, external fixation, open reduction, and plate fixation. is there. Of these, plate fixation, particularly internal fixation in which the plate is directly applied to the surface of the bone inside the skin, has recently been used frequently because the mechanism does not become large because the mechanism stays in the vicinity of the fracture and the fixation force is strong. In this regard, internal fixation with a plate is also recommended for fractures at the distal radius.

この内固定を果たす内固定器具は、骨折個所をまたがって骨の表面にあてがわれ、ビスで橈骨に固定されるプレートと、プレートから骨内に向けて刺入されるペグとからなるものであるが、従来の内固定器具を橈骨の遠位端骨折に適用したのでは、関節に近隣する遠位端には曲げや回旋の力が強くかかる上に骨片が小さいことから、十分な固定力が得られない。特に、回旋力によってプレートが橈骨表面上で滑りを起こしたりして位置がずれたりすることがあった。このため、固定に緩みが出る等して治癒が遅れたりすることがあった。
特開2002−153478
The internal fixation device that achieves this internal fixation consists of a plate that is applied to the surface of the bone across the fracture site and fixed to the rib with a screw, and a peg that is inserted from the plate into the bone. However, when the conventional internal fixation device is applied to the fracture of the distal end of the radius, the distal end adjacent to the joint is strongly bent and rotated, and the bone fragment is small. I can't get power. In particular, the rotational force may cause the plate to slip on the rib surface and shift its position. For this reason, healing may be delayed due to loosening of fixation.
JP 2002-153478 A

本発明が解決しようとする課題は、骨に対するプレートの固定力を強め、曲げ力や回旋力がかかっても、プレートの位置がずれず、緩みが出ないようにしたものである。なお、本出願人等は、上腕骨の骨折の内固定器具として本発明に類した案件を上記特許文献1で提案しているが、本発明は、これよりも更にプレートの固定力を高めたものである。   The problem to be solved by the present invention is to increase the fixing force of the plate to the bone so that the plate does not shift and does not come loose even when a bending force or a rotating force is applied. In addition, although this applicant etc. have proposed the matter similar to this invention in the said patent document 1 as an internal fixation device of the fracture of a humerus, this invention raised the fixing force of the plate further than this. Is.

以上の課題の下、本発明は、請求項1に記載した、橈骨遠位端の骨折個所を固定する橈骨遠位端骨折用内固定器具であり、この内固定器具が、遠位端の解剖学的形状に沿うように湾曲させられて骨折個所をまたいで橈骨の表面にあてがわれ、ビスで橈骨に固定されるるプレートと、プレートから橈骨内に刺入されるペグとからなるものであり、プレートには、ビス挿入孔が敵数と、貫通孔を有するインローが少なくとも二個形成されており、ビス挿入孔からビスを橈骨内に螺入するとともに、インローを橈骨に形成されたポケットに嵌入し、かつ貫通孔からペグを橈骨内に刺入してプレートを橈骨に固定したことを特徴とする橈骨遠位端骨折用内固定器具を基本的構成として提供する。   Under the above-mentioned problems, the present invention is the internal fixation device for fracture of the distal radius, which fixes the fracture site of the distal radius, according to claim 1, and this internal fixation device is used for dissecting the distal end. It is made up of a plate that is curved to conform to the geometrical shape, applied to the surface of the rib across the fracture site, and fixed to the rib with a screw, and a peg inserted into the rib from the plate The plate has at least two screw insert holes and through-holes with through-holes. Screws are screwed into the ribs from the screw insert holes, and the inserts are inserted into pockets formed in the ribs. An internal fixation device for fracture of the distal radius is provided as a basic configuration, which is inserted and a peg is inserted into the radius from the through hole and the plate is fixed to the radius.

以上の手段をとることにより、すなわち、橈骨に形成されたポケットに嵌まり込むインローを二個以上設けたものであるから、曲げ力や回旋力が働いても、プレートの位置がずれず、緩みを生じさせない。   By taking the above measures, that is, since there are two or more inlays that fit into the pockets formed in the ribs, the plate position does not shift and loosen even if bending force or rotating force is applied. Does not cause.

以下、本発明の実施の形態を図面を参照して説明する。図1は本発明に係る橈骨遠位端骨折用内固定器具A(以下、内固定器具という)の縦断面図、図2は平面図、図3は内固定器具Aを撓骨にあてがった場合の透視図であるが、前腕には橈骨1と尺骨2とが存在し、その遠位端で掌の手根骨3と関節を構成している。橈骨1が骨折したとき(この骨折は、骨厚が薄い遠位端に多い)、その骨折個所に内固定器具Aをあてがう。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a longitudinal sectional view of an internal fixation device A for fracture of the distal radius according to the present invention (hereinafter referred to as an internal fixation device), FIG. 2 is a plan view, and FIG. 3 is a case where the internal fixation device A is applied to a radius. In the forearm, the radius 1 and the ulna 2 exist in the forearm, and the distal end thereof constitutes the joint with the carpal bone 3 of the palm. When the rib 1 is fractured (this fracture is often at the distal end where the bone thickness is thin), the internal fixation device A is applied to the fracture site.

内固定器具Aは、橈骨1の表面にあてがわれ、ビス4で橈骨1に固定されるプレート5と、プレート5から橈骨1内に刺入されるペグ6とからなる。これにおけるプレート5は、厚さ0.5〜3mm程度のチタン等の生体適合金属板を素材として幅4〜10mm、長さ20〜100mm程度に設定される。加えて、この内固定器具Aは、橈骨1の遠位端に適用されるものであるから、その解剖学的形状に合わせて上方が外側に膨らんだ湾曲に形成されている。   The internal fixation device A includes a plate 5 that is applied to the surface of the rib 1 and is fixed to the rib 1 with screws 4, and a peg 6 that is inserted into the rib 1 from the plate 5. The plate 5 in this case is set to a width of about 4 to 10 mm and a length of about 20 to 100 mm using a biocompatible metal plate such as titanium having a thickness of about 0.5 to 3 mm. In addition, since the internal fixation device A is applied to the distal end of the radius 1, the internal fixation device A is formed in a curved shape whose upper side swells outward in accordance with its anatomical shape.

プレート5には、ビス4が挿入されるビス挿入孔7が適数と、貫通孔8が形成されたインロー9が裏面に少なくとも二個突設されている。本例のビス挿入孔7は、皿小ネジのビス4を通すもので、インロー9の下方に五個、上方に一個形成されているが、いずれも皿もみされており、しかも、皿もみ面は球面をした球面孔に形成されている。   The plate 5 has an appropriate number of screw insertion holes 7 into which the screws 4 are inserted, and at least two inlays 9 with through holes 8 formed on the back surface thereof. The screw insertion hole 7 of this example is for passing the screw 4 of the countersunk screw, and is formed in the lower part of the inlay 9 and one in the upper part. Is formed in a spherical hole.

一方、本例のインロー9は、プレート5の上方側に二個形成されており、その中心線はプレート5に対してやや下向き(5°程度)に設定されている。プレート5を橈骨1の遠位端にあてがった場合、貫通孔8に通されるペグ5が骨軸に直角に近くなるようにしたものである。インロー9の外径は5mm程度で、突出長さは3〜5mm程度に設定されている。貫通孔8は、M5のネジ9aが形成されたザグリ穴10と、ザグリ穴10に続く直径径4mm程度の球面孔11とからなるものである。   On the other hand, two inlays 9 in this example are formed on the upper side of the plate 5, and the center line is set slightly downward (about 5 °) with respect to the plate 5. When the plate 5 is applied to the distal end of the rib 1, the peg 5 that is passed through the through hole 8 is close to the bone axis at a right angle. The outer diameter of the inlay 9 is set to about 5 mm, and the protruding length is set to about 3 to 5 mm. The through-hole 8 is composed of a counterbore hole 10 in which an M5 screw 9 a is formed, and a spherical hole 11 having a diameter of about 4 mm following the counterbore hole 10.

プレート5を固定するために用いられる皿小ネジのビス4は、同じく生体適合金属で構成されたもので、頭部4aの裏面が上記したビス挿入孔7の球面孔に沿う球体に形成されたものを使用する。ビス4をビス挿入孔7中で動かせるようにし、固定に効果的な方向に螺入できるようにするためである。この場合におけるビス4の太さは1.5〜2mm程度のものを使用し、長さは個々において調整できるように種々に設定してある。   The countersunk screw 4 used to fix the plate 5 is also made of a biocompatible metal, and the back surface of the head 4a is formed in a spherical shape along the spherical hole of the screw insertion hole 7 described above. Use things. This is because the screw 4 can be moved in the screw insertion hole 7 and can be screwed in a direction effective for fixing. In this case, the thickness of the screw 4 is about 1.5 to 2 mm, and the length is variously set so that it can be adjusted individually.

ペグ6も、同じく生体適合金属で構成されており、太さ2〜3mm程度のものを使用する。この場合のペグ6は、頭部6aと胴部6bとからなるもので、本例のものにおける頭部6aは、貫通孔8の球面孔11に沿う球体に形成されている。なお、頭部6aの頂端にはレンチが挿入されるレンチ穴6cも形成されている。本例の胴部6bにはネジが形成されているが、単にピン状のものもある。   The peg 6 is also made of a biocompatible metal and has a thickness of about 2 to 3 mm. The peg 6 in this case is composed of a head portion 6 a and a body portion 6 b, and the head portion 6 a in this example is formed in a spherical body along the spherical hole 11 of the through hole 8. A wrench hole 6c into which a wrench is inserted is also formed at the top end of the head 6a. A screw is formed on the body portion 6b of this example, but there is also a simple pin shape.

次に、以上の内固定器具Aを用いる使用方法(手術)について説明する。まず、皮膚を切開して予め判明している骨折個所をまたがるようにプレート5を橈骨1の表面にあてがう。このとき、下方のインロー9とその下のビス挿入孔7との間に骨折ラインLが来るようにするのがベストであるが、骨折個所によってはそのようにできないことがあるから、これに近い形でセットする。ただし、その場合でも、プレート5自体は骨折ラインLをまたがるようにセットする必要がある。   Next, the usage method (surgery) using the above internal fixation device A will be described. First, the plate 5 is applied to the surface of the rib 1 so as to straddle the fracture site that has been previously determined by incising the skin. At this time, it is best to make the fracture line L come between the lower inlay 9 and the screw insertion hole 7 therebelow, but this may not be possible depending on the fracture location. Set in shape. However, even in that case, the plate 5 itself needs to be set so as to cross the fracture line L.

そして、インロー9が来る位置の橈骨1にこのインロー9が嵌入できるポケット12を形成する。このポケット12は、インロー9がきっちりと根元まで入る程度に形成する。以上が終了すると、プレート5を橈骨1にあてがい(インロー9をポケット12に嵌入し)、ビス挿入孔7からビス4を橈骨1内に螺入する。このとき、ビス4をビス挿入孔7中で動かしてできるだけ骨軸に直角になるようにして固定力の強化を図る。なお、この場合、すべてのビス挿入孔7にビス4を通すのが原則であるが、骨折の程度や場所(プレート5をあてがう位置)によっては適当に省略することがある。   And the pocket 12 which can insert this inlay 9 in the rib 1 of the position where the inlay 9 comes is formed. The pocket 12 is formed to such an extent that the inlay 9 can be inserted into the base. When the above is completed, the plate 5 is applied to the rib 1 (the inlay 9 is inserted into the pocket 12), and the screw 4 is screwed into the rib 1 from the screw insertion hole 7. At this time, the fixing force is strengthened by moving the screw 4 in the screw insertion hole 7 so as to be as perpendicular to the bone axis as possible. In this case, in principle, the screws 4 are passed through all the screw insertion holes 7, but may be appropriately omitted depending on the degree and location of the fracture (position to which the plate 5 is applied).

次いで、ペグ6を貫通孔8に通して橈骨1内に刺入する。この刺入(螺入)は、頭部6aのレンチ穴6cにレンチを嵌めて行なう。ペグ6による骨の固定は、骨折骨の小片と大片を互いに牽引して或いは小片をプレート5に牽引して固定するものであるから、胴部6bにはネジが形成されているものが適する。加えて、胴部6bは、骨折ラインLを横切るようにするのが理想であるが、骨折個所によってはそれができないことがあるから、その場合は、できるだけ骨折ラインLに近づくように刺入する。この点で、胴部6bの長さには種々のものが設定してあり、最適なものを選択する。なお、粉砕骨折しているような場合、胴部6bをその骨片に突き刺してプレート5側に引き寄せて固定するようなことも行なわれる。   Next, the peg 6 is inserted into the rib 1 through the through-hole 8. This insertion (screwing) is performed by fitting a wrench into the wrench hole 6c of the head 6a. The fixation of the bone by the peg 6 is performed by pulling a small piece and a large piece of the fractured bone together or by pulling the small piece to the plate 5 so that the body portion 6b is preferably provided with a screw. In addition, it is ideal that the torso 6b crosses the fracture line L. However, since this may not be possible depending on the fracture location, in this case, the body 6b is inserted as close to the fracture line L as possible. . In this respect, various lengths of the body 6b are set, and an optimum one is selected. In the case where the fracture is broken, the body 6b is pierced into the bone fragment and pulled toward the plate 5 to be fixed.

ペグ6が骨折部の所定の個所に刺入されたなら、貫通孔8のザグリ穴10に、そのネジ9aに螺合できるネジ13aが外周に形成され、中心にレンチ孔13bが形成されたロックナット13をネジ込んでペグ6の頭部6aを押さえ付けてその姿勢、方向で固定する。このときのロックナット13の前面は、頭部6aの球体に沿う球面に形成してある。したがって、ロックナット13をねじ込んだときには、ペグ6がどの方向を向いていようとも、ペグの頭部6aは、ロックナット13の前面と貫通孔8の球面孔11に隙間なく接触して強く締め付けられ、強固に固定されて動くことはない。なお、ロックナット13の長さは、これをザグリ穴10に螺合したとき、その頭部はザグリ穴10から覗かない程度に設定するのが適する。   When the peg 6 is inserted into a predetermined portion of the fractured part, a screw 13a that can be screwed into the screw 9a is formed in the counterbore hole 10 of the through hole 8, and a wrench hole 13b is formed in the center. The nut 13 is screwed and the head 6a of the peg 6 is pressed and fixed in its posture and direction. The front surface of the lock nut 13 at this time is formed into a spherical surface along the sphere of the head 6a. Therefore, when the lock nut 13 is screwed in, no matter which direction the peg 6 is facing, the head 6a of the peg is in contact with the front surface of the lock nut 13 and the spherical hole 11 of the through-hole 8 without any gap and is tightened strongly. It is fixed firmly and does not move. The length of the lock nut 13 is suitably set so that its head does not look into the counterbore hole 10 when it is screwed into the counterbore hole 10.

以上で、骨折個所の固定ができたから、皮膚を縫合して骨折が治癒するまでこの状態に止めておく。このように、本発明の内固定器具Aを用いると、プレート5には橈骨1に形成されたポケット12に嵌め込まれるインロー9が少なくとも二個形成されているから、骨折個所に力がかかっても、プレート5の位置がずれず、固定に緩みが発生しない。特に、関節に近い橈骨1の遠位端近辺には強い回旋力が働くから、これによるずれ防止の効果は大きい。また、ペグ6も、当然に二本刺入され、加えて、その刺入方向を任意に設定できるものであるから、固定にもっとも効果的で、かつ強い固定力を得られるように調整できる。この意味で、インロー9及びペグ6を三個以上にすれば、より高いずれ防止と固定力が得られる。   Now that the fracture site has been fixed, the skin is sutured and kept in this state until the fracture is healed. As described above, when the internal fixation device A of the present invention is used, the plate 5 is formed with at least two inlays 9 to be fitted in the pockets 12 formed in the rib 1, so that even if a force is applied to the fracture site. The position of the plate 5 does not shift and no loosening occurs. In particular, since a strong rotational force acts near the distal end of the radius 1 close to the joint, the effect of preventing this deviation is great. Also, since the peg 6 is naturally inserted into two pegs and the insertion direction can be arbitrarily set, the peg 6 can be adjusted so as to be most effective for fixing and obtain a strong fixing force. In this sense, if the number of inlays 9 and pegs 6 is three or more, higher prevention and fixing force can be obtained.
