Abstract
Description
La présente invention concerne un dispositif chirurgical pour contrôler, au cours d'une intervention, le positionnement relatif du fémur par rapport au bassin, lors d'une arthroplastie de la hanche. The present invention relates to a surgical device for controlling, during an intervention, the relative positioning of the femur relative to the pelvis, during a hip arthroplasty.
La géométrie de la partie supérieure du fémur diffère beaucoup d'un individu à un autre, tant par les dimensions des éléments comme la tête ou le col du fémur, que par les angles que font ces éléments entre eux ou avec la diaphyse fémorale. The geometry of the upper part of the femur differs greatly from one individual to another, as much by the dimensions of the elements as the head or the neck of the femur, as by the angles that these elements make with each other or with the femoral shaft.
L'usure de la tête fémorale dans la cavité cotyloidienne peut entraîner une dissymetrie des deux hanches qu'il est possible de rétablir au moment de l'arthroplastie. Wear of the femoral head in the acetabulum can cause asymmetry in both hips, which can be restored at the time of the joint replacement.
En conséquence, l'arthroplastie de la hanche nécessite, avant l'ablation des parties osseuses, une étude géométrique du positionnement dans l'espace du fémur par rapport au bassin. Consequently, hip arthroplasty requires, before the removal of the bony parts, a geometric study of the positioning in space of the femur relative to the pelvis.
De façon à remplacer, d'une manière aussi géométriquement parfaite que possible, la partie supérieure du fémur, les prothèses offrent toujours au praticien un choix modulaire de plusieurs longueurs de col et parfois plusieurs positions du col par rapport à la collerette d'appui. In order to replace, in as geometrically perfect a manner as possible, the upper part of the femur, the prostheses always offer the practitioner a modular choice of several neck lengths and sometimes several positions of the neck relative to the support flange.
Ce choix est actuellement effectué préalablement à l'intervention à partir de clichés radiologiques. This choice is currently made prior to the intervention from radiological images.
Cependant, la détermination des longueurs réelles à partir de ces mesures radiographiques est délicate et une erreur est donc toujours possible, sans qu'il existe actuellement d'ancillaire susceptible de vérifier au cours de l'intervention si, par exemple, la latéralisation du fémur par rapport au bassin est satisfaisante.However, determining the actual lengths from these radiographic measurements is delicate and an error is therefore always possible, without there currently being any ancillary device capable of verifying during the intervention if, for example, the lateralization of the femur relative to the pelvis is satisfactory.
Cette erreur ne deviendra évidente que lorsque le patient reprendra la marche : une claudication et des douleurs musculaires constituant le triste résultat d'une erreur géométrique. This error will only become evident when the patient resumes walking: claudication and muscle pain constituting the sad result of a geometric error.
Le dispositif décrit dans la présente invention est destiné à éviter cette erreur géométrique, en contrôlant au cours de l'intervention que certains positionnements anatomiques comme la latéralisation, ou la longueur du membre, sont bien conformes au souhait du chirurgien. The device described in the present invention is intended to avoid this geometric error, by checking during the intervention that certain anatomical positions such as lateralization, or the length of the limb, are indeed in accordance with the wishes of the surgeon.
En cas d'anomalie, il est alors encore possible de choisir parmi les éléments modulaires offerts au praticien, celui qui va convenir le mieux. Après quoi, l'intervention peut se conclure au mieux des intérêts du patient. In the event of an anomaly, it is then still possible to choose from among the modular elements offered to the practitioner, the one that will best suit. After which, the intervention can be concluded in the best interests of the patient.
Le dispositif selon l'invention permet de repérer, dans un référentiel fixe, une poutre démontable liée au bassin, les positions de certains points ou directions anatomiques, appartenant à l'extrémité supérieure du fémur, comme un point du grand trochanter par exemple. The device according to the invention makes it possible to locate, in a fixed reference frame, a removable beam linked to the pelvis, the positions of certain anatomical points or directions, belonging to the upper end of the femur, such as a point of the greater trochanter for example.
D'autres caractéristiques et avantages de l'invention apparaîtront de la description et des dessins annexes, qui présentent un mode de réalisation préférentiel de l'invention. Other characteristics and advantages of the invention will appear from the description and the accompanying drawings, which show a preferred embodiment of the invention.
La figure 1 représente en perspective le dispositif selon l'invention. Figure 1 shows in perspective the device according to the invention.
La figure 2 représente une variante du dispositif précédent où la liaison du dispositif au bassin est assurée par une seule vis. Figure 2 shows a variant of the previous device where the connection of the device to the pelvis is provided by a single screw.
En référence à la figure 1, le dispositif comporte une poutre prismatique en T (1), percée longitudinalement (2), destinée à recevoir un index (3) coulissant le long d'une graduation (4) inscrite sur la grande longueur du T qui comporte à la jonction avec sa branche courte (5) une tige filetée (6) destinée à permettre la fixation, au moyen d'un écrou par exemple, d'une poutre (7) parallèle à la branche courte qui vient pincer des broches (8) ou des vis (9) préalablement fixées dans le bassin et chemisées ou non par un manchon (10). Referring to Figure 1, the device comprises a prismatic T-beam (1), pierced longitudinally (2), intended to receive an index (3) sliding along a graduation (4) inscribed on the long length of the T which comprises at the junction with its short branch (5) a threaded rod (6) intended to allow the fixing, by means of a nut for example, of a beam (7) parallel to the short branch which pinches pins (8) or screws (9) previously fixed in the basin and jacketed or not by a sleeve (10).
Le dispositif constitue alors avec sa poutre graduée, un référentiel rigide fixé, en porte à faux, au bassin, aisément montable ou démontable. The device then constitutes with its graduated beam, a rigid reference frame fixed, cantilevered, to the basin, easily mountable or dismountable.
La figure 1 montre aussi comment le dispositif, relié au bassin, permet de déterminer les coordonnées XAet d'un point A par exemple. FIG. 1 also shows how the device, connected to the basin, makes it possible to determine the coordinates XA and of a point A for example.
La description du montage du dispositif permettra de mettre en évidence l'originalité et la qualité du dispositif selon une réalisation préférentielle mais non limitative. The description of the assembly of the device will make it possible to highlight the originality and the quality of the device according to a preferential but not limiting embodiment.
Après avoir accompli les gestes préparatoires à une arthroplastie de la hanche, le chirurgien commence par fixer deux broches chirurgicales telles que (8) de 3 mm de diamètre par exemple. Cette fixation a nécessité la traversée de la masse musculaire située au dessus du sourcil cotyloïdien. After performing the preparatory gestures for a hip replacement, the surgeon begins by attaching two surgical pins such as (8) 3 mm in diameter for example. This fixation required the crossing of the muscle mass located above the acetabular eyebrow.
Le long d'une des broches, le praticien fait glisser un manchon (10) de diamètre intérieur légèrement supérieur à 3,5 mm à travers la masse musculaire jusqu'au contact du bassin. Along one of the pins, the practitioner slides a sleeve (10) with an internal diameter slightly greater than 3.5 mm through the muscle mass until it contacts the pelvis.
Le chirurgien peut alors retirer la broche en laissant le manchon et la remplacer par une vis (9) de diamètre 3,5 mm qui va plaquer l'extrémité distale du manchon sur le bassin. A ce stade du montage, la broche (8) et la vis (9) font saillie de quelques millimètres de la masse musculaire mais ne perturbent pas la liberté de mouvement autour de l'extrémité supérieure du fémur. The surgeon can then remove the pin leaving the sleeve and replace it with a screw (9) with a diameter of 3.5 mm which will press the distal end of the sleeve on the pelvis. At this stage of assembly, the pin (8) and the screw (9) protrude a few millimeters from the muscle mass but do not disturb the freedom of movement around the upper end of the femur.
Le chirurgien peut alors solidariser au bassin la poutre en T, en coinçant les extrémités proximales de la vis (9) et de la broche (8) entre les deux ailes parallèles de la branche courte (5) du T. La vis (6) assure ce pincement. The surgeon can then secure the T-beam to the pelvis, wedging the proximal ends of the screw (9) and the pin (8) between the two parallel wings of the short branch (5) of the T. The screw (6) ensures this pinching.
Le chirurgien peut donc maintenant se servir du dispositif pour mesurer les coordonnées du point A de la figure 2 par exemple, avant de procéder au démontage de la poutre (1) par dévissage de (6) puis à l'arthroplastie proprement dite. The surgeon can therefore now use the device to measure the coordinates of point A in FIG. 2 for example, before dismantling the beam (1) by unscrewing from (6) and then by the arthroplasty itself.
Après la pose de la prothèse, le chirurgien peut à nouveau fixer le dispositif sur la vis (9) et la broche (8), qui sont restées en attente sans gêner l'opération1 et vérifier que le nouveau positionnement du point A correspond à ses voeux. After placing the prosthesis, the surgeon can again fix the device on the screw (9) and the spindle (8), which have remained on hold without interfering with the operation1 and check that the new positioning of point A corresponds to its wishes.
Il reste, soit à modifier la géométriede la prothèse, soit à démonter le dispositif et terminer l'intervention si le nouveau positionnement est satisfaisant. It remains either to modify the geometry of the prosthesis, or to dismantle the device and complete the intervention if the new positioning is satisfactory.
On peut remarquer qu'il serait possible de solidariser le dispositif au moyen d'une vis traversant longitudinalement (2) la poutre, vis qui traverserait la masse musculaire dans un manchon posé comme cela a été décrit plus haut pour la vis (9). La pose du dispositif est plus rapide et sa stabilité suffisante dans bien des cas. It can be noted that it would be possible to secure the device by means of a screw passing longitudinally (2) the beam, a screw which would pass through the muscle mass in a sleeve placed as described above for the screw (9). The installation of the device is faster and its stability sufficient in many cases.
La figure 2 représente une variante de cette dernière version du dispositif. Elle consiste à rendre solidaire un manchon (12) et la poutre en T. Ceci implique le remplacement de la vis par une broche entre les deux séries de mesures. Figure 2 shows a variant of this latest version of the device. It consists in joining a sleeve (12) and the T-beam. This involves replacing the screw with a pin between the two series of measurements.
