Description
本発明は、鎖骨が骨折したときに使用する鎖骨固定用プレートに関するものである。 The present invention relates to a clavicle fixing plate used when a clavicle fractures.
鎖骨は胸骨と肩峰との間に介在する平面視Ｓ字状に湾曲した骨であり、肩甲骨が前に倒れるのを防止している。鎖骨は比較的細長く、大腿骨、橈骨及び上腕骨等の長骨と同様に骨折頻度の高い骨として知られている。鎖骨における骨折は遠位部分に多く見られるが、骨折治療の基本は、骨折個所を接合して強固に固定することであり、鎖骨においても同様である。 The clavicle is a bone curved in an S-shape in a plan view interposed between the sternum and the acromion, and prevents the scapula from falling forward. The clavicle is relatively long and narrow, and is known as a bone having a high fracture frequency like the long bones such as the femur, the rib and the humerus. Fractures in the clavicle are often found in the distal part, but the basis of fracture treatment is to join and firmly fix the fracture site, and the same applies to the clavicle.
骨折した鎖骨を癒合させるためには、保存療法と手術療法とがあり、前者は骨折した患部をバンドや帯で拘束して整復位を保つ方法であり、主に小児に適用されている。後者には、ピン等を骨折した個所を通して髄内に挿入する髄内固定法と、プレートを骨表面に沿わせて固定するプレート固定法とがある。このうち、プレート固定法は切開域が大きくなって大きな傷跡を残すものの、骨折した鎖骨を直接整復できて早期の癒合が望めることから、比較的多く採用されている。 In order to unite the fractured clavicle, there are conservative therapy and surgical therapy, and the former is a method of constraining the fractured affected part with a band or a band to keep the reduction position, and is mainly applied to children. The latter includes an intramedullary fixation method in which a pin or the like is inserted into the medulla through a broken part and a plate fixation method in which the plate is fixed along the bone surface. Among them, the plate fixation method is relatively widely used because it can reduce the fractured clavicle directly and can expect early healing, although the incision area becomes large and leaves a large scar.
鎖骨固定用プレートには、下記特許文献１で示されるような鎖骨の形状に沿ったプレートのみのものと、プレートに肩峰や鎖骨自身に係止するフックを形成したものとがある。いずれのものも、プレートの部分にはスクリュー孔が形成されており、このスクリュー孔にスクリューを挿入して鎖骨にネジ込む（螺入する）のであるが、プレートのみのものでは、固定力が十分ではないとの指摘がある。 The clavicle fixing plate includes a plate having only a shape of the clavicle as shown in Patent Document 1 below, and a plate having a hook for locking the shoulder crest or the clavicle itself. In both cases, a screw hole is formed in the plate part, and a screw is inserted into this screw hole and screwed into the clavicle. There is an indication that it is not.
そこで、フックの有用性が出てくるのであり、図７はプレートａに設けられたフックｂを肩峰ｃに係止するものであるが、これによると、フックｂが鎖骨ｄの遠位端と肩鎖関節ｅを跨ぐため、可動域制限があって術後の早期の可動域訓練が行えない。また、フックｂが周囲の骨、特に、肩峰ｃを骨折させる虞もある。図８はフックｂで鎖骨ｄの遠位部分を挟むものであるが、抜去時にフックｂの曲直しが必要になったりして却って手術時間が長くなることがある。加えて、粉砕骨折の場合は固定力が十分ではない。なお、鎖骨は上記した特有の形状をしており、他の長骨の骨折用プレートをそのまま用いたのでは機能が不十分であり、鎖骨骨折専用のプレートによるのが好ましい。 Therefore, the utility of the hook comes out, and FIG. 7 shows the hook b provided on the plate a being locked to the shoulder crest c. According to this, the hook b is connected to the distal end of the clavicle d. Because of this, the range of motion is limited and early range of motion training after surgery cannot be performed. In addition, the hook b may break the surrounding bone, particularly the shoulder crest c. In FIG. 8, the distal portion of the clavicle d is sandwiched between the hooks b. However, the operation time may be increased because the hooks b need to be bent again at the time of removal. In addition, in the case of a crushed fracture, the fixing force is not sufficient. The clavicle has a unique shape as described above. If a plate for fracture of another long bone is used as it is, the function is insufficient, and it is preferable to use a plate exclusively for clavicle fracture.
本発明は、プレートの形状、構造を固定力の強いものにするとともに、スクリュー孔の数や配置を効果的に設定することで、十分で安定した固定力を発揮させるようにしたものである。 In the present invention, the shape and structure of the plate have a strong fixing force, and the number and arrangement of screw holes are effectively set so that a sufficient and stable fixing force is exhibited.
以上の課題の下、本発明は、請求項１に記載した、骨折した鎖骨の上面に沿って遠位部分と近位部分とに亘って当てがわれる鎖骨固定用プレートであり、このプレートが鎖骨の上方から螺入される複数の固定スクリューを挿入する固定スクリュー孔が形成された本体プレートからなるものであり、本体プレートの遠位部から前垂れが垂下しており、この前垂れに鎖骨の遠位部分に前方から螺入される前方固定スクリューを挿入する前方固定スクリュー孔が形成されているとともに、本体プレートの中央付近に肩甲骨の烏口突起に上方から螺入される固定用スクリューよりも径太な烏口突起固定スクリューを挿入する烏口突起固定スクリュー孔が形成されていることを特徴とする鎖骨固定用プレートを提供したものである Under the above-mentioned problems, the present invention is the clavicle fixation plate applied to the distal portion and the proximal portion along the upper surface of the fractured clavicle according to claim 1, and this plate is the clavicle. The body plate is formed with a fixing screw hole into which a plurality of fixing screws to be screwed in from above is formed, and the front sag hangs down from the distal part of the body plate. A front fixing screw hole for inserting a front fixing screw that is screwed into the part from the front is formed, and the diameter of the front fixing screw is larger than that of the fixing screw that is screwed in from the upper side of the scapular protuberance near the center of the body plate. The present invention provides a clavicle fixing plate characterized in that a throat protrusion fixing screw hole for inserting a throat protrusion fixing screw is formed.
また、本発明は、以上の鎖骨固定用プレートにおいて、請求項２に記載した、固定スクリューが遠位部分に螺入される主固定スクリューと近位部分に螺入される副固定スクリューとからなるものであり、直径２.０〜３.５mmの主固定スクリューを挿入する主固定スクリュー孔が近位部方向に向けて３〜４列で５〜１５個形成されている構成、請求項３に記載した、主又は/及び副固定スクリューのいずれか又は全部が幅又は長さ方向に傾けられている構成、請求項４に記載した、前方固定スクリュー孔が直径２.０〜３.５mmの固定スクリューを挿入できるものである構成、請求項５に記載した、烏口突起固定スクリュー孔が
直径５〜８mmの烏口突起固定スクリューを挿入できるものである構成を提供する。
Further, the present invention is the above clavicle fixing plate, comprising the main fixing screw into which the fixing screw is screwed into the distal portion and the auxiliary fixing screw to be screwed into the proximal portion. is intended that the structure is mainly set screw holes for inserting the main stationary screw diameter 2.0~3.5mm are made 5-15 pieces shaped by 3-4 rows toward the proximal portion direction, claim 3 5. A configuration in which any or all of the main and / or auxiliary fixing screws described above are inclined in the width or length direction, and the front fixing screw hole according to claim 4 has a diameter of 2.0 to 3.5 mm. A configuration in which a fixing screw can be inserted, and a configuration in which a throat protrusion fixing screw hole having a diameter of 5 to 8 mm can be inserted as described in claim 5 are provided.
請求項１の発明では、本体プレートに鎖骨に上方から螺入されて鎖骨を固定する固定スクリューを挿入する固定スクリュー孔が形成されている他、骨折が多く発生する鎖骨の遠位部分前方を覆う前垂れが設けられていて、この前垂れに前方から螺入されて鎖骨を固定する前方固定スクリューが挿入できる前方固定スクリュー孔が形成されている。加えて、本体プレートのほぼ中央にこの下に存在する肩甲骨の烏口突起に上方から螺入されて烏口突起に固定される烏口突起固定スクリュー孔が形成されている。したがって、これら各スクリュー孔に各々のスクリューを螺入することで鎖骨を本体プレートで幅広い範囲で、しかも、鎖骨の表面に沿って上下及び側方に（立体的に）締め付けることになり、固定力を効率的に、しかも、強く発揮させて早期の癒合が可能になる。 According to the first aspect of the present invention, a fixing screw hole is formed to insert a fixing screw that is screwed into the clavicle from above to fix the clavicle, and covers the front of the distal portion of the clavicle where fractures frequently occur. A front hanging screw hole is formed, and a front fixing screw hole into which a front fixing screw that is screwed into the front hanging from the front to fix the clavicle can be inserted. In addition, a throat protrusion fixing screw hole is formed in the center of the main body plate so as to be screwed into the scapular heel protrusion existing below the scapula and fixed to the throat protrusion. Therefore, by screwing each screw into each of these screw holes, the clavicle is clamped in a wide range with the main body plate, and vertically and laterally (three-dimensionally) along the surface of the clavicle. Efficiently and strongly exerts early healing.
これにおいて、本体プレートは肩峰に係止したり、鎖骨自身を挟むフックのようなものは形成されていないため、周囲の骨や肩峰を骨折させる虞がない上に、抜去に際して曲直しも必要ない。さらに、本体プレートは鎖骨の遠位端から肩鎖関節を跨いでいないから、可動域を制限する事態が少なく、術後早期に可動域訓練ができる。請求項２〜５の手段によると、より立体的で効率的な締付けになるとともに、強力な固定力を発揮する。 In this case, since the body plate is not locked to the shoulder crest or a hook that sandwiches the clavicle itself, there is no risk of fracture of the surrounding bone or shoulder crest, and the body plate may be bent during removal. unnecessary. Furthermore, since the main body plate does not straddle the acromioclavicular joint from the distal end of the clavicle, there are few situations where the range of motion is limited, and the range of motion training can be performed early after the operation. According to the means of Claims 2-5, it becomes more three-dimensional and efficient tightening, and exhibits a strong fixing force.
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は本発明に係る鎖骨固定用プレート（以下、プレートという）の平面図、図２は図１のＡ−Ａ断面図であるが、このプレートは、本体プレート１を主体とし、これに前垂れ２が形成されたものである。本体プレート１は、鎖骨３の上面に当てがわれるもので、それぞれ遠位部分と近位部分に対応する遠位部１ａと近位部１ｂとを有している。なお、本例では、遠位部１ａの厚みは３ｍｍ程度、近位部１ｂの厚みは２ｍｍ程度に設定されている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a clavicle fixing plate (hereinafter referred to as a plate) according to the present invention, and FIG. 2 is a cross-sectional view taken along the line AA of FIG. 2 is formed. The main body plate 1 is applied to the upper surface of the clavicle 3, and has a distal portion 1a and a proximal portion 1b corresponding to the distal portion and the proximal portion, respectively. In this example, the thickness of the distal portion 1a is set to about 3 mm, and the thickness of the proximal portion 1b is set to about 2 mm.
本体プレート１は、チタン合金等の生体適合金属で形成された平板状のもので、平面視で鎖骨３の形状に沿って湾曲した形状に形成されている。前垂れ２は、鎖骨３の遠位部分の前面に当てがわれるもので、本体プレート１と通常は一体で設けられており、遠位部１ａの前面に約９０°の角度で垂下し、垂下する丈は鎖骨３の遠位部分の厚みとほぼ同じである。 The main body plate 1 is a flat plate formed of a biocompatible metal such as a titanium alloy, and is formed in a shape curved along the shape of the clavicle 3 in plan view. The front sag 2 is applied to the front surface of the distal portion of the clavicle 3, and is usually provided integrally with the main body plate 1, and hangs at an angle of about 90 ° from the front surface of the distal portion 1a. The length is substantially the same as the thickness of the distal portion of the clavicle 3.
本体プレート１の遠位部１ａ側には、少なくとも５個以上の主固定スクリュー孔４が形成されている。本例では、近位部分に向けて３列で合計１０個の主固定スクリュー孔４が形成されているが、これに限定されるものではない。数は多いほどよいが、スペース等の関係で４〜５列で１５個程度が限度になる。なお、この主固定スクリュー孔４は本体プレート１に対して直角ばかりではなく、幅方向や長さ方向に若干（約１０°程度）傾けて形成されているものがある。 At least five main fixing screw holes 4 are formed on the distal portion 1 a side of the main body plate 1. In this example, a total of ten main fixing screw holes 4 are formed in three rows toward the proximal portion, but the present invention is not limited to this. The larger the number, the better, but the limit is about 15 in 4-5 rows due to space and the like. The main fixing screw hole 4 is formed not only at a right angle to the main body plate 1 but also slightly inclined (about 10 °) in the width direction or the length direction.
また、近位部１ｂにも副固定スクリュー孔５が形成されており、本例では、３個設けられているが、このうち、中央側のものは近位部分に向けて長孔になっている。後述する副固定スクリューを最適な個所に螺入できるようにするためである。なお、この副固定スクリュー孔５の数もこれに限定されるものではない。 Further, the sub-fixed screw hole 5 is also formed in the proximal portion 1b, and in this example, three are provided. Of these, the central one is a long hole toward the proximal portion. Yes. This is because a sub-fixing screw to be described later can be screwed into an optimum place. Note that the number of the auxiliary fixing screw holes 5 is not limited to this.
本体プレート１のほぼ中央の下方には肩甲骨６の烏口突起７が存在しているが、この部分にも烏口突起固定スクリュー孔８が形成されている。この烏口突起固定スクリュー孔８も、上記した副固定スクリューの場合と同じ目的で近位部分に向けて長孔になっている。また、数は１個であるが、２個以上であってもよい。さらに、前垂れ２にも、固定スクリュー孔４と同程度の径を有する前方固定スクリュー孔９が形成されている。なお、前方固定スクリュー孔９は通常１個形成されるが、２個以上であってもよい。 A throat projection 7 of the scapula 6 is present below the center of the main body plate 1, and a throat projection fixing screw hole 8 is also formed in this portion. The throat protrusion fixing screw hole 8 is also a long hole toward the proximal portion for the same purpose as in the case of the auxiliary fixing screw described above. The number is one, but it may be two or more. Further, a front fixing screw hole 9 having a diameter similar to that of the fixing screw hole 4 is also formed in the front sag 2. In addition, although one front fixing screw hole 9 is normally formed, two or more may be sufficient.
図３はプレートの使用状態を示す平面図、図４は裏面からみた断面図、図５は縦断面図、図６は図５のＢ−Ｂ矢視図であるが、主固定スクリュー孔４には主固定スクリュー１０が、副固定スクリュー孔５には副固定スクリュー１１が、前方固定スクリュー孔９には前方固定スクリュー１２が、烏口突起固定スクリュー孔８には烏口突起固定スクリュー１３がそれぞれ挿入されて鎖骨３及び烏口突起７に螺入される。なお、副固定スクリュー１１はすべての副固定スクリュー孔５で使用されないこともある。 3 is a plan view showing the state of use of the plate, FIG. 4 is a cross-sectional view seen from the back side, FIG. 5 is a vertical cross-sectional view, and FIG. 6 is a view taken along arrow BB in FIG. The main fixing screw 10 is inserted into the auxiliary fixing screw hole 5, the front fixing screw 12 is inserted into the front fixing screw hole 9, and the throat protrusion fixing screw 13 is inserted into the throat protrusion fixing screw hole 8. Then, it is screwed into the clavicle 3 and the mouth projection 7. The sub-fixing screw 11 may not be used in all the sub-fixing screw holes 5.
この場合、各スクリュー孔４、５、８、９は座繰り穴に形成されており、各スクリュー１０〜１３はその頭部がこの中に埋め込まれるようになっている（表面に出ない）。加えて、各スクリュー１０〜１３は各スクリュー孔４、５、８、９の中で多少の向きを変えて挿入できるようになっている。さらに、各スクリュー１０〜１３を頭部にもネジが形成されたロッキングスクリューを使用すれば、緩み防止効果が一層高くなる。 In this case, each screw hole 4, 5, 8, 9 is formed in a countersink hole, and the head of each screw 10-13 is embedded in this (it does not come out on the surface). In addition, the screws 10 to 13 can be inserted in the screw holes 4, 5, 8, and 9 while being slightly changed in direction. Furthermore, if each screw 10-13 uses the locking screw in which the screw was formed also in the head, the loosening prevention effect will become still higher.
これら各スクリュー１０〜１３とも、その材質は本体プレート１と同じくチタン合金等の生体適合金属で構成されている。なお、主固定スクリュー４と前方固定スクリュー１２の径は２．０〜３．５ｍｍ程度、副固定スクリュー１１の径はそれよりもやや太く、烏口突起固定スクリュー１３の径は５〜８ｍｍ程度に設定されている。 Each of these screws 10 to 13 is made of a biocompatible metal such as a titanium alloy like the main body plate 1. The diameter of the main fixing screw 4 and the front fixing screw 12 is set to about 2.0 to 3.5 mm, the diameter of the auxiliary fixing screw 11 is slightly thicker than that, and the diameter of the mouthpiece protrusion fixing screw 13 is set to about 5 to 8 mm. Has been.
鎖骨固定用プレートで骨折した鎖骨３を固定する手術については、従来の固定用プレートの手術と同様である。ただ、この固定用プレートを鎖骨３に当てがったとき、その形状・構造の特異性によって次のような作用を果たす。まず、第一に、遠位部１ａに螺入される数多くの主固定スクリュー１０によって（鎖骨３の骨折は遠位部に数多く見られるので、この主固定スクリュー１０が骨折部分に跨がって集中的に螺入される）骨折個所を接合しての固定力が高まる。この場合、主固定スクリュー孔４の傾きに基づいて主固定スクリュー１０が螺入される方向を違えることで、鎖骨３の表面形状により沿い、かつ、締付け効果を高める。 The operation of fixing the fractured clavicle 3 with the clavicle fixing plate is the same as the conventional operation of the fixing plate. However, when this fixing plate is applied to the clavicle 3, the following effects are achieved depending on its shape and structure. First, by means of a large number of main fixation screws 10 screwed into the distal portion 1a (since many fractures of the clavicle 3 are seen at the distal portion, the main fixation screw 10 straddles the fracture portion. Fixing force is increased by joining fractured parts (screwed in intensively). In this case, by changing the direction in which the main fixing screw 10 is screwed in based on the inclination of the main fixing screw hole 4, the tightening effect is enhanced along the surface shape of the clavicle 3.
第二に、前垂れ２に形成された前方固定スクリュー孔９から螺入される前方固定スクリュー１３が大きな意味を有している。図４に見られるように、この前方固定スクリュー１３を螺入した場合、主固定スクリュー１０の螺入方向が個々に違うことと相まって固定スクリュー１０の間を縫うように後方に延びている。この点で、前方固定スクリュー孔９と主固定スクリュー孔４とは互いが干渉しないようにその方向及び配置を考慮する必要がある。このように、主固定スクリュー１０と前方固定スクリュー１３とで鎖骨３を上方及び前方の二面から個々が異なる方向に立体的に締め付けるので、固定力は一層高まる。 Secondly, the front fixing screw 13 screwed from the front fixing screw hole 9 formed in the front sag 2 has a great meaning. As seen in FIG. 4, when the front fixing screw 13 is screwed in, the main fixing screw 10 extends backward so as to sew between the fixing screws 10 in combination with different screwing directions. In this respect, it is necessary to consider the direction and arrangement of the front fixing screw hole 9 and the main fixing screw hole 4 so that they do not interfere with each other. In this way, the main fixation screw 10 and the front fixation screw 13 tighten the clavicle 3 three-dimensionally in different directions from the upper and front two surfaces, so that the fixation force is further increased.
第三に、烏口突起固定スクリュー孔８から螺入される他のスクリューよりも太い烏口突起固定スクリュー１３が更なる強力な固定力を発揮する。ただ、この固定は、鎖骨３の自由度を奪ってしまので、あくまで術後の初期固定を目的とし、ある程度癒合が確認された後は抜去して早期の可動域訓練ができるようにするのが適する。一方で、このように、烏口突起固定スクリュー１３を使用することには一定の弊害もあるので、骨折が軽度であるような場合には、烏口突起固定スクリュー１３を使用しないこともある。 Thirdly, the throat protrusion fixing screw 13 that is thicker than the other screws screwed from the throat protrusion fixing screw hole 8 exhibits a further strong fixing force. However, this fixation takes away the degree of freedom of the clavicle 3, so it is intended only for the initial fixation after the operation, and after a certain degree of fusion has been confirmed, it can be removed to enable early range of motion training. Suitable. On the other hand, since the use of the throat projection fixing screw 13 has certain adverse effects, the ostium projection fixing screw 13 may not be used when the fracture is mild.
