Abstract

The invention relates to an osteosynthesis helping device, i.e. an osteosynthesis plate (4), which can be firmly connected to a medullary pin (3). At the same time, it relates especially to an osteosynthesis helping device for femoral neck fractures, comprising a medullary pin (3) for the proximal region (A) of the femoral bone, a connection provided on its outer end for an osteosynthesis plate, and an osteosynthesis plate having bores for the reception of bone screws (6, 2), one set of bone screws (6) serving to fix the osteosynthesis plate on the femur and the other set of bone screws (2) serving to connect the osteosynthesis plate (4) to the neck of the femur, and, furthermore, the bores having a transversal spacing which is larger than the diameter of the medullary pin (3). It is also possible to fix an osteosynthesis plate to the head of the humerus by means of screws to which a medullary pin can be firmly connected. <IMAGE>

Description

Oppfinnelsen angår et osteosyntese-hjelpemiddel ifølge innledningen til krav 1. The invention relates to an osteosynthesis aid according to the introduction to claim 1.

I US-PS 47 3 3 654 foreslås et spesielt osteosyntese-hjelpemiddel for å holde lårhalsen og det øvre lårhalshodet i ro, ved hvilket en ytterligere nagledel er festbar i det proksimale området av margnaglen, hvilken har hull for opptak av en spesielt lang knokkelskrue (benskrue). Osteosynteseplaten er utformet som en L og griper med sitt korte øvre skrått utstående ben inn i denne ytterlige del av margnaglen. Dette osteosyntese-hjelpemiddel fremtvinger således, på grunn av det foreliggende hull i margnaglen og i tilleggskonstruk-sjonsdelen, fastlagte skruretninger, dvs. at anbringelsen og retningen av skruen ikke er varierbar. In US-PS 47 33 654 a special osteosynthesis aid is proposed for keeping the femoral neck and the upper femoral head still, whereby a further nail part is fixable in the proximal area of the medullary nail, which has a hole for receiving a particularly long bone screw ( leg screw). The osteosynthesis plate is shaped like an L and engages with its short upper obliquely protruding leg into this outer part of the medullary nail. This osteosynthesis aid thus forces, due to the present hole in the medullary nail and in the additional construction part, fixed screw directions, i.e. that the placement and direction of the screw is not variable.

Europeisk patentsøknad 347 874 beskriver en innretning for å forbinde et ben som er brukket, spesielt i området ved lårhalsen, men denne publikasjonen beskriver ikke et osteosyntese-h jelpemiddel i forbindelse med en margnagle. European patent application 347 874 describes a device for connecting a bone that has been fractured, particularly in the area of the femoral neck, but this publication does not describe an osteosynthesis aid in connection with a marrow nail.

I europeisk patentsøknad 251 583 fremstilles i fig. 5 et lårhalsbrudd som stabiliseres over en margnagle 9, men det anvendes heller ikke her noen osteosyntese-plate som ifølge foreliggende oppfinnelsen. In European patent application 251 583, fig. 5 a femoral neck fracture which is stabilized over a marrow nail 9, but no osteosynthesis plate is used here either, as according to the present invention.

I tysk utlegningsskrift 31 14 136 beskrives det en osteosynteseplate, men denne står ikke i forbindelse med en margnagle som i foreliggende løsning. In German specification 31 14 136, an osteosynthesis plate is described, but this is not connected to a marrow nail as in the present solution.

Det er oppfinnelsens oppgave å tilveiebringe en mekanis-me som fremskaffer bedre sikring av osteosynteseplaten ved at skruens retning kan velges fritt, slik at det med de enkleste hjelpemidler kan oppnås en tilstrekkelig forankring og fast-holdelse av lårhalsen, og den store rullebøylen fastholdes gjennom osteosynteseplaten. It is the task of the invention to provide a mechanism that provides better securing of the osteosynthesis plate by allowing the direction of the screw to be chosen freely, so that with the simplest aids a sufficient anchoring and retention of the femoral neck can be achieved, and the large roller brace is retained through the osteosynthesis plate .

Denne oppfinnelsens grunnleggende oppgave blir løst gjennom læren i hovedkravet. The basic task of this invention is solved by the teachings of the main claim.

Fordelaktige utførelser er beskrevet i underkravene. Advantageous designs are described in the sub-claims.

Uttrykt med andre ord, foreslås det at ved et pertrokantært øvre lårhalsbrudd i det proksimale området av det øvre lårhalsbenet, innsettes en margnagle som strekker seg til den store rullebøylen, og som i sin øvre ende oppviser en - eksempelvis som skrue i den proksimale ende av margnaglen - utformet tilslutningsanordning for en osteosynteseplate. Osteosynteseplaten har mange hull for opptak av benskruer, idet den transversale avstanden for hullene er større enn margnaglenes diameter, slik at skruretningen ikke er forutbe-stemt på grunn av tilsvarende opptakshull i margnaglen. Herigjennom kan hullene anbringes slik at skruene som settes inn i den føres forbi på begge sider av margnaglen og føres til øvre lårhalshode, hvorved retningen til skruen er valg-fri. Expressed in other words, it is proposed that in the case of a pertrochanteric fracture of the upper femoral neck in the proximal area of the upper femoral neck, a marrow nail is inserted which extends to the large roller hoop, and which at its upper end exhibits a - for example as a screw in the proximal end of marrow nail - designed attachment device for an osteosynthesis plate. The osteosynthesis plate has many holes for receiving bone screws, as the transverse distance for the holes is greater than the diameter of the spinal nails, so that the screw direction is not predetermined due to corresponding reception holes in the spinal nail. Through this, the holes can be positioned so that the screws that are inserted into it are passed on both sides of the spinal nail and are led to the upper femoral neck head, whereby the direction of the screw is free of choice.

Herigjennom oppnås en sikrere fastsettelse av lårhalsen og av det øvre lårhalsbenet i det proksimale området til det øvre lårhalshodet, hvorved denne sikrere fastgjøringen i alt vesentlig er oppnåelig med de nåværende vanlige instrumenter. This achieves a more secure fixing of the femoral neck and of the upper femoral neck bone in the proximal area of the upper femoral neck head, whereby this more secure fixing is essentially achievable with the current common instruments.

Videre foreslås det ifølge oppfinnelsen at anordningen også ved et overarmsbrudd i området til overarmhodet anvendes ifølge oppfinnelsen, idet margnaglen oppviser en slik lengde at den strekker seg fra overarmhodet og inn i overarmbenet. Furthermore, according to the invention, it is proposed that the device is also used in the case of a fracture of the upper arm in the area of the humeral head according to the invention, as the medullary nail has such a length that it extends from the humeral head into the humerus.

Utførelseseksempler av oppfinnelsen blir ved hjelp av vedføyde tegninger belyst. Tegningene viser i Exemplary embodiments of the invention are illustrated with the help of the attached drawings. The drawings show i

fig. 1 et delriss av den proksimale enden til et øvre lårben, i fig. 1 is a partial view of the proximal end of an upper femur, i

fig. 2 et snitt ifølge linjen 2-2 i fig. 1, og i fig. 2 a section according to line 2-2 in fig. 1, and i

fig. 3 et overarmsben med osteosyntese-hjelpemiddel. I fig. 1 betegner A et øvre lårben, B lårhalsen og C det øvre lårhodet. I den proksimale enden til det øvre lårben A, er en margnagle 3 innsatt, som ved sin ytre øvre ende oppviser en gjengetilslutning 1, med hvilken tilkoplingen av en osteosynteseplate 4 på margnaglen 3 er mulig. Osteosynteseplaten 4 har flere hull 5, gjennom hvilke de lange benskruene 2 og korte benskruer 6 er innsettbare. De korte benskruer 6 fast-gjør derved osteosynteseplaten 4 på det øvre lårbenet A, mens de lange benskruer 2 føres inn i det øvre lårhalshodet C og dermed fastholder dette området på det øvre lårbenet. fig. 3 a humerus with an osteosynthesis aid. In fig. 1, A denotes an upper femur, B the femoral neck and C the upper femoral head. At the proximal end of the upper femur A, a marrow nail 3 is inserted, which at its outer upper end exhibits a threaded connection 1, with which the connection of an osteosynthesis plate 4 to the marrow nail 3 is possible. The osteosynthesis plate 4 has several holes 5, through which the long bone screws 2 and short bone screws 6 can be inserted. The short bone screws 6 thereby fasten the osteosynthesis plate 4 on the upper femur A, while the long bone screws 2 are inserted into the upper femoral head C and thus secure this area on the upper femur.

Som det tydelig vises i fig. 1, og som fig. 2 også tydelig viser, er boringen 5 således anordnet for opptak av skruer 2 og 6, at de innsatte skruene forløper på begge sider av de innsatte margnaglene 3 og således føres til det øvre lårhodet. Herigjennom er ingen direkte forbindelse med margnaglen nødvendig, slik at det her unngås kompliserte nagle-konstruksj oner. As is clearly shown in fig. 1, and as fig. 2 also clearly shows, the bore 5 is arranged in such a way to receive screws 2 and 6, that the inserted screws extend on both sides of the inserted marrow nails 3 and are thus led to the upper femoral head. As a result, no direct connection with the core rivet is necessary, so that complicated rivet constructions are avoided.

Ved utførelsesformen ifølge fig. 3 er en øvre armbensdel beskrevet med et overarmshode D og et overarmsben E. Ved overarmshodet D, er en osteosynteseplate 4a fastgjort, og oppviser hullene 5a for opptak av festeskruen. Videre kan det til denne osteosynteseplaten 4a fast tilsluttes en margnagle 3a, slik at beliggenheten til disse margnaglene gjennom den ved overarmhodet fastgjorte osteosyntesplate blir fast-holdt. In the embodiment according to fig. 3, an upper humerus part is described with a humerus head D and a humerus bone E. At the humerus head D, an osteosynthesis plate 4a is attached, showing the holes 5a for receiving the fixing screw. Furthermore, a medullary nail 3a can be firmly connected to this osteosynthesis plate 4a, so that the position of these medullary nails is maintained through the osteosynthesis plate attached to the head of the upper arm.
