Abstract

There is at least one holder (1) set transverse or inclined to the long axis of the bone in the area away from the epicondylus. There is also at least one stabiliser (2) set transverse or inclined to the bone and connected to the holder so that the holder does not disturb the fabric surrounding nerves of the bone. The holder is formed of a threaded rod which is screwed into the epicondyli. The stabiliser is also formed of a rod which is rigidly attached to the holder by a threaded attachment device (3). The rods are made of metal or reinforced plastics. ADVANTAGE - Provides for better extraneous fixing of the bone.

Description

Die Erfindung betrifft ein Verfahren zur externen Fixierung eines gebrochenen Oberarmknochens und Vorrichtungen zur Durchführung des Verfahrens nach den Patentansprüchen.The invention relates to a method for external fixation of a broken humerus and devices for carrying out of the method according to the claims.

Bei der bekannten externen Fixierung eines gebrochenen Oberarmknochens werden die Haltemittel 1 in die jeweiligen Knochenteile eingeschraubt und mit einem parallel zur Knochenlängsachse verlaufenden Stabilisierungsmittel 2 fest verbunden. Bei diesem bekannten Verfahren und der bekannten Vorrichtung zu seiner Durchführung verläuft das körperferne Haltemittel 1 immer in einem Bereich, in dem ein für die Bewegung der Hand wichtiger Nerv am Oberarmknochen liegt. Es handelt sich hierbei um den Nervus radialis. Das Gewinde des Haltemittels kann das den Nervus radialis unmittelbar umgebende Gewebe beim Einschrauben in das Knochenteil erfassen und diesen Nerv aufwickeln und so seine Funktion beeinträchtigen.In the known external fixation of a broken humerus, the holding means 1 are screwed into the respective bone parts and firmly connected to a stabilizing means 2 running parallel to the longitudinal axis of the bone. In this known method and the known device for carrying it out, the holding means 1 remote from the body always runs in an area in which a nerve important for the movement of the hand lies on the humerus. This is the radial nerve. The thread of the holding means can grip the tissue immediately surrounding the radial nerve when it is screwed into the bone part and wind up this nerve and thus impair its function.

Deshalb werden bisher externe Fixierungen eines gebrochenen Oberarmknochens nur dann vorgenommen, wenn eine interne Fixierung eines gebrochenen Oberarmknochens nicht mehr möglich ist.For this reason, external fixations have so far been broken Upper arm bone only made when there is internal fixation a broken humerus is no longer possible.

Von daher liegt der Erfindung die Aufgabe zugrunde, ein Verfahren und Vorrichtungen zu seiner Durchführung zu finden, die eine bessere externe Fixierung eines gebrochenen Oberarmknochens ermöglichen.The invention is therefore based on the object of a method and to find devices for its implementation, which a better external fixation of a broken humerus enable.

Zur Lösung dieser Aufgabe werden die Gegenstände der Patentansprüche vorgeschlagen.To solve this problem, the objects of Claims proposed.

Die Zeichnung zeigt ein Beispiel einer Vorrichtung nach der Erfindung.The drawing shows an example of a device according to the Invention.

Die Zeichnung zeigt einen an einer Stelle gebrochenen Oberarmknochen 4. Im oberen, körpernahen Knochenteil sind zwei Haltemittel 1 eingeschraubt. Diese Haltemittel 1 sind über Schraubverbindungen 3 fest mit den beiden Stabilisierungsmitteln 2 verbunden. Im körperfernen Knochenteil sind die Haltemittel 1 schräg in die Knochenvorwölbungen, den Epicondyli, eingeschraubt. Nur in diesem Bereich des Oberarmknochens ist das Condylen vorhanden, wodurch sich der Begriff Epicondylus erklärt. Diese Knochenvorspünge, Epicondyli, sind von der Hautoberfläche vom behandelnden Arzt sicher zu ertasten und er kann so beim Einsetzen der Haltemittel 1 die Epicondyli nicht verfehlen. Eine Beeinträchtigung des Nervus radialis ist so insbesondere wegen der schrägen Anordnung der Haltemittel 1 und der Stabilisierungsmittel 2 ausgeschlossen.The drawing shows an upper arm bone 4 broken at one point. Two holding means 1 are screwed into the upper part of the bone close to the body. These holding means 1 are firmly connected to the two stabilizing means 2 via screw connections 3 . In the bone part remote from the body, the holding means 1 are screwed diagonally into the bony protrusions, the epicondyli. Condyling is only present in this area of the humerus, which explains the term epicondyle. These bone protrusions, epicondyli, can be palpated safely by the attending physician from the skin surface and he cannot miss the epicondyli when inserting the holding means 1 . Impairment of the radial nerve is excluded, in particular because of the oblique arrangement of the holding means 1 and the stabilizing means 2 .
