Abstract
Description
Broche cannelée déradée à Dointe boutonnée
L'invention concerne les broches utilisées couramment en chirurgie orthopédique et traumatologique pour la synthèse des fractures proximales de l'humérus, du fémur et d'autres os longs.Fluted spindle with dointe buttoned
The invention relates to pins commonly used in orthopedic and trauma surgery for the synthesis of proximal fractures of the humerus, femur and other long bones.
Les broches habituellement utilisées en chirurgie orthopédique ont un diamètre constant et une extrémité pointue agressive capable de perforer les cartilages articulaires. L'autre extrémité, une fois la broche sectionnée à la longueur souhaitée, reste agressive pour la peau et les tissus de voisinage car non protégée. The pins usually used in orthopedic surgery have a constant diameter and an aggressive pointed end capable of perforating the articular cartilages. The other end, once the spindle is cut to the desired length, remains aggressive for the skin and surrounding tissues because it is not protected.
L'invention s'est fixée pour but de remédier à ces incovénients de manière simple, sûre, efficace et rationnelle. The invention has set itself the aim of remedying these disadvantages in a simple, safe, effective and rational manner.
Le problème que se propose de résoudre l'invention est: - d'assurer une bonne stabilité du foyer de fracture en zone métaphysaire, - de rendre non agressives les 2 extrémités des broches utilisées et introduites dans le canal médullaire. The problem which the invention proposes to solve is: - to ensure good stability of the fracture site in the metaphyseal zone, - to make the 2 ends of the pins used and introduced into the medullary canal non-aggressive.
Pour résoudre un tel problème la broche comporte d'un côté: - une extrémité cannelée propre à recevoir un capuchon protecteur (brevet N) 9607911 déposé en date du 20/06/96) - de l'autre une extrémité terminée par un bouton béquillé de diamètre supérieur à l'extrémité cannelée: cette différence de diamètre permet d'améliorer la stabilité du foyer de fracture mieux rempli par le matériel d'ostéosynthèse qui le rigidifie. To solve such a problem, the spindle has on one side: - a grooved end suitable for receiving a protective cap (patent N) 9607911 filed on 20/06/96) - on the other end terminated by a crutch button with a diameter greater than the grooved end: this difference in diameter makes it possible to improve the stability of the fracture site better filled by the osteosynthesis material which stiffens it.
L'autre extrémité cannelée et moins volumineuse permet d'introduire dans le canal médullaire au travers de la fenêtre corticale un nombre de broches plus important qui concourt également à améliorer la stabilité du foyer de fracture. Après perforation de la corticale externe à l'aide d'une pointe carrée, la broche est montée à l'aide d'un mandrin dans le canal médullaire pointe boutonnée en avant. L'extrémité béquillée et boutonnée permettra un passage facilité du foyer de fracture même en l'absence de réduction anatomique. L'extrémité boutonnée évitera les effractions du cartilage articulaire ou de léser les éléments nobles en cas de fausse route.The other grooved and less bulky end allows to introduce into the medullary canal through the cortical window a larger number of pins which also contributes to improving the stability of the fracture site. After perforation of the external cortex using a square point, the spindle is mounted using a mandrel in the medullary canal, point buttoned forward. The crutched and buttoned end will allow easier passage of the fracture site even in the absence of anatomical reduction. The buttoned end will prevent breakage of the articular cartilage or damage the noble elements in the event of a false route.
Le plus gros diamètre de la broche du côté de l'extrémité boutonnée permet un meilleur remplissage du foyer de fracture, gage de stabilité en zone métaphysaire. En dehors de la zone utile à la stabilité du foyer de fracture, la broche se rétrécie afin de pouvoir introduire sans difficulté par une fenêtre corticale de dimension donnée, un maximum de broches divergentes qui vont également concourir à améliorer la stabilité du montage. Lorsque le positionnement de la broche est satisfaisant, celle-ci est sectionnée à la longueur adéquate. L'extrémité sectionnée qui reste extériorisée par rapport à la corticale est généralement agressive, source de douleur, de perforation cutanée, d'infection et de traumatisme pour les éléments de voisinage. L'aspect cannelé de la broche permet de remédier à cet inconvénient en permettant l'application d'un capuchon protecteur à expansion sur la zone renflée de la partie cannelée. The larger diameter of the pin on the side of the buttoned end allows better filling of the fracture site, a guarantee of stability in the metaphyseal zone. Outside the zone useful for the stability of the fracture site, the spindle narrows in order to be able to introduce without difficulty by a cortical window of given size, a maximum of divergent pins which will also contribute to improving the stability of the assembly. When the positioning of the spindle is satisfactory, it is cut to the appropriate length. The severed end which remains exteriorized with respect to the cortex is generally aggressive, a source of pain, skin perforation, infection and trauma for the neighboring elements. The fluted appearance of the spindle overcomes this drawback by allowing the application of a protective expansion cap on the swollen area of the fluted portion.
Dans ces conditions, on comprend qu'avec de telles broches on optimise: - le remplissage intra-canalaire en regard du foyer de fracture métaphysaire par augmentation du diamètre utile de la broche au niveau du siège de la fracture. Under these conditions, it is understood that with such pins it optimizes: - the intra-canal filling opposite the focal point of the metaphyseal fracture by increasing the useful diameter of the pin at the level of the seat of the fracture.
- la stabilité du foyer de fracture par un nombre plus important de broches mises en place grâce à un encombrement minimal au niveau de la fenêtre corticale évitant ainsi de mettre en place un matériel volumineux sous la peau et la création éventuelle de refend osseux au niveau de la corticale trépanée.- the stability of the fracture site by a larger number of pins placed thanks to a minimal space requirement at the cortical window thus avoiding placing bulky material under the skin and the possible creation of bone splitting at the trepanic cortex.
- la tolérance des broches est bien meilleure car rendue inoffensive à leurs 2 extrémités : d'un côté une extrémité boutonnée introduite dans l'os, de l'autre un capuchon protecteur épargne la peau et les organes de voisinage (tendon, nerf, artère).- the tolerance of the pins is much better because made harmless at their 2 ends: on one side a buttoned end introduced into the bone, on the other a protective cap spares the skin and neighboring organs (tendon, nerve, artery ).
Les broches utilisées sont des broches souples et peuvent avoir un diamètre et une longueur variables. Le matériau utilisé peut-être du titane, de l'acier inoxydable ou tout autre matériau biocompatible. La partie la plus renflée (1) comportant l'extrémité boutonnée et avantageusement béquillée sera de longueur variable adaptée au type anatomique de la fracture traitée, son diamètre sera également variable. The pins used are flexible pins and can have a variable diameter and length. The material used may be titanium, stainless steel or any other biocompatible material. The most swollen part (1) comprising the buttoned and advantageously crutched end will be of variable length adapted to the anatomical type of the fracture treated, its diameter will also be variable.
La partie lisse (3) sera également de longueur et de diamètre variables.The smooth part (3) will also be of variable length and diameter.
La partie cannelée (4) sera de longueur variable. The grooved part (4) will be of variable length.
L'invention est exposée ci-après plus en détail à l'aide des dessins annexés dans lesquels: - la figure 1 est une vue longitudinale de la broche cannelée dégradée à pointe boutonnée.The invention is set out below in more detail with the aid of the appended drawings in which: - Figure 1 is a longitudinal view of the degraded fluted spindle with button point.
- la figure 1 bis est une vue longitudinale capuchon en place.- Figure 1a is a longitudinal view with the cap in place.
- la figure 2 montre un exemple d'utilisation pour une fracture du col de l'humérus.- Figure 2 shows an example of use for a humeral neck fracture.
Comme le montre la figure 1 cette broche comporte une partie renflée (1), propre à stabiliser efficacement le foyer de fracture. Cette broche est ensuite de diamètre rétréci (3) afin de réduire son encombrement et permettre la mise en place d'un nombre important de broches, gage supplémentaire de stabilité. As shown in Figure 1 this pin has a bulged part (1), capable of effectively stabilizing the fracture site. This pin is then of narrowed diameter (3) in order to reduce its bulk and allow the installation of a large number of pins, an additional guarantee of stability.
Cette broche est rendue non agressive par une extrémité boutonnée (2) d'un côté et par l'application à l'autre extrémité d'un capuchon protecteur (5) sur la partie cannelée (4) une fois la broche sectionnée. This pin is made non-aggressive by a buttoned end (2) on one side and by the application at the other end of a protective cap (5) on the grooved part (4) once the pin has been cut.
Les avantages ressortent bien de la description, en particulier on souligne et on insiste sur: - la stabilité du foyer de fracture améliorée par le gros calibre de la broche en zone utile et par l'intérêt de l'effilement du diamètre dans la position située en dehors du foyer de fracture et surtout au voisinage de la fenêtre corticale. The advantages clearly emerge from the description, in particular it emphasizes and emphasizes: outside the fracture site and especially in the vicinity of the cortical window.
- la possibilité grâce à cet artifice de monter un nombre plus conséquent de broches dans le foyer fracturaire sans risque de refend au niveau de la corticale trépanée.- the possibility thanks to this device to mount a more substantial number of pins in the fracture zone without risk of splitting at the level of the trepaneal cortex.
- inocuité des broches protégées à leurs 2 extrémités par un bouton d'une part et par un capuchon protecteur d'autre part.- safety of the pins protected at their 2 ends by a button on the one hand and by a protective cap on the other.
L'aspect avantageusement béquillé de son extrémité boutonnée favorisant le passage plus aisé du foyer fracturaire. The advantageously crutched aspect of its buttoned end promoting easier passage of the fracture hearth.
