Title
(DE) SCHALE ZUM EINSCHLAGEN IN EINE KNOCHENSUBSTANZ FÜR EINE GELENKPROTHESE
(EN) SHELL TO BE DRIVEN INTO A BONE SUBSTANCE FOR A PROSTHETIC JOINT
(FR) COQUILLE DESTINÉE À ÊTRE ENFONCÉE DANS UNE SUBSTANCE OSSEUSE POUR UNE PROTHÈSE DE LA HANCHE
Abstract
(DE)
Eine Schale (1) für eine Gelenkprothese zum Einschlagen in eine Knochensubstanz hat eine im Querschnitt konvex gekrümmte Aussenmantelfläche (4), auf der eine Mehrzahl von Rippen (5) angeordnet sind. Alle Rippen erstrecken sich gleichsinnig unter einem vorzugsweise zunehmenden Steigungswinkel von 45° bis 85°, am äquatorialen Ende (6) zu einem polseitigen Ende (7). Die kumulierte Flankenprojektionsfläche aller Rippen (5) entspricht wenigstens einem Fünftel der ganzen Aussenmantelfläche. Durch diese Massnahme wird eine sehr hohe Primärstabilität nach dem Einschlagen erzielt, wobei sich die Schale sehr präzise und ohne Abscheren von Knochenmaterial in die Knochensubstanz eindreht. Diese Anordnung lässt sich in analoger Weise auch auf eine konkav gekrümmte Innenmantelfläche anwenden.
(EN)
A shell (1) for a prosthetic joint to be driven into a bone substance, said shell having an outer lateral surface (4) which is convexly curved in cross section and on which a plurality of ribs (5) is arranged. All ribs extend in the same direction at a preferably increasing gradient angle of 45° to 85° at the equatorial end (6) to a pole-side end (7). The cumulative flank projection area of all ribs (5) corresponds to at least a fifth of the entire outer lateral surface. As a result of this measure, a very high primary stability is achieved once the shell has been driven in, the shell being screwed into the bone substance very precisely and without bone material being sheared off. This arrangement can also be applied, similarly, to a concavely curved inner lateral surface.
(FR)
L'invention concerne une coquille (1) pour une prothèse de la hanche destinée à être enfoncée dans une substance osseuse. La coquille comprend une surface enveloppante extérieure (4) incurvée de manière convexe dans la section transversale, sur laquelle sont disposées une multitude de nervures (5). Toutes les nervures s'étendent dans le même sens selon un angle de pas de préférence croissant allant de 45° à 85° sur l'extrémité équatoriale (6) vers une extrémité polaire (7). La surface de projection de flanc cumulée de toutes les nervures (5) correspond à au moins un cinquième de l'ensemble de la surface enveloppante extérieure. Cette mesure permet d'atteindre une stabilité primaire très élevée après l'enfoncement, la coquille étant introduite par rotation dans la substance osseuse avec une précision élevée et sans cisaillement. Cet agencement peut également être appliqué de manière analogue sur une surface enveloppante intérieure incurvée de manière concave.
