Atraumatischer SchenkelhalsnagelAtraumatic femoral neck nail
Die Erfindung betrifft einen atraumatischen Schenkelhalsnagel, der für medizinische Zwecke zum Fixieren des Schenkelkopfes bei dessen Bruch oder Epiphysiolise dient.The invention relates to an atraumatic femoral neck nail, which is used for medical purposes to fix the femoral head in the event of its fracture or epiphysiolise.
Aufgabe der Erfindung ist es, die Nachteile der bekannten Schenkelhalsnägel zu vermeiden, insbesondere einen Schenkelhalsnagel mit geringerer axialer und radialer Treibwirkung zu schaffen, und zwar unter gleichzeitiger Verbesserung der Halterungswirkung.The object of the invention is to overcome the disadvantages of the known Avoid femoral neck nails, especially a femoral neck nail to create with less axial and radial driving effect, while improving at the same time the retention effect.
Der erfindungsgemäße atraumatische Sohenkelhalsnagel zum Fixieren des Schenkelkopfes bei dessen Bruch oder Epiphysiolise ist dadurch gekennzeichnet, daß er einen zylinderförmigen Kopf mit einem Hals aufweist und daß der im Querschnitt mehrkantige, insbesondere dreikantige Rumpf an seinen äußeren Rand-Längskanteh Verdiokiingen besitzt.The atraumatic sole neck nail according to the invention for fixing the femoral head in the event of its fracture or Epiphysiolise is characterized in that it has a cylindrical head with a neck and that the trunk, which is polygonal in cross-section, in particular triangular on its outer edge longitudinal edges, Verdiokiingen owns.
Besonders vorteilhaft ist es, wenn sich die Verdickungen gegen die Nagelspitze hin in spitz zulaufende freie Enden fortsetzen, wobei insbesondere die Verdickungen und die freien Enden etwa zylindrischen Querschnitt aufweisen.It is particularly advantageous if the thickenings continue towards the tip of the nail in tapering free ends, in particular the thickenings and the have free ends approximately cylindrical cross-section.
Der Vorteil gegenüber allen bisher bekannten Schenkelhalsnägeln besteht darin, daß siine Spitze nicht kompakt ist, sondern aus drei nadelartigen Endungen besteht. Bei der Verwendung dringen nur die nadelartigen Endungen in den oberen Teil des Schenkelhalses, und in den abgebroohenen Schenkelkopf ein.The advantage over all previously known femoral neck nails is that its tip is not compact, but consists of three needle-like endings. When using only the needle-like endings penetrate into the upper part of the femoral neck and into the broken femoral head a.
Mit dem erfindungsgemäßen Sohenkelhalsnagel werden folgende Vorteile erreicht ιThe following advantages are achieved with the sole handle neck nail according to the invention

BADBATH
a. Minimale Beschädigung des schon durch das Trauma beeinträchtigten Blutumlaufs des Schenkelkopfes.a. Minimal damage to the blood circulation in the femoral head, which has already been impaired by the trauma.
b. Leichteres Eindringen wegen des geringeren Widerstandes, wodurch wiederum die Distraktion der Fragmente verhindert wird.b. Easier penetration because of the lower resistance, which in turn results in the distraction of the fragments is prevented.
c. Wegen derselben Eigenschaften dringt der erfindungsgemäße Schenkelhalsnagel auch leichter in ältere, skierotische Knochen ein und zerbröckelt und vernichtet zudem nicht die geschwächte Struktur des osteoporotischen Knochens, welche In der Mehrzahl des Materials seiner Indikation vorkommen.c. Because of the same properties, the invention penetrates Femoral neck nail also more easily penetrates older, skierotic bones and crumbles and destroys also not the weakened structure of the osteoporotic bone, which in the majority of the material its indication.
d. Im Falle, daß es nicht gelingen sollte, ihn im Zentrum des Kopfes zu placieren, besteht keine Gefahr, daß er durch sein Vordringen exzentrisch rotieren und die Fragmente des Schenkelkopfes dislozieren wird, welche auf diese Weise ihre ursprüngliche Lage beibehalten.d. In the event that it does not work, put him in the center of the head, there is no danger that it will rotate eccentrically as a result of its advance and the Will dislocate fragments of the femoral head, which in this way retain their original position.

Der traumatishe Schenkelhalsnagel besteht aus einem zylinderf örmigen Kopf 1 mit einem zugehörigen Hals 2 sowie aus einem etwa dreikantigen Rumpf 3 und spitz zulaufenden Enden 4 der im wesentlichen zylinderförmig verdickten Rand-Längskanten des Rumpfes 3. Der Schenkelhalsnagel ist der Länge^nah zentral durchlocht. Diese Längsbohrung dient zur Aufnahme eines Führungsdrahts. Der Rumpf 3 kann auch aus zwei oder mehr als drei Kanten bestehen und es kann in einzelnen Fällen auch von Vorteil sein, wenn nicht alle Rand-Längskanten die zylinderförmige Verdickung mit den spitz zulaufenden Enden 4 aufweisen. Auch können die Verdickungen der Rand-Längskanten einen anderen als zylinderf örmigen Querschnitt aufweisen.The traumatic femoral neck nail consists of a cylindrical head 1 with an associated neck 2 as well from an approximately triangular body 3 and tapering to a point Ends 4 of the thickened substantially cylindrical Edge-long edges of the trunk 3. The femoral neck nail is perforated in the center to the length ^ close. This longitudinal bore serves to hold a guide wire. The fuselage 3 can also consist of two or more than three edges and it can also be advantageous in individual cases, if not all longitudinal edges have the cylindrical thickening with the tapering ends 4. They can also Thickenings of the edge longitudinal edges have a cross-section other than cylindrical.
Der atraumatische Schenkelhalsnagel wird, dirigiert durch den Führungsdraht, nach der Methode Smith-Peters«n, von der Außenseite des Schenkelknochens unter dem Trochanter major eingeführt. -The atraumatic femoral neck nail is directed through the guide wire, using the Smith-Peters method, from the outside of the thighbone under the greater trochanter introduced. -
