Abstract

Abstract Translated from German Ein sich zum distalen Ende in der Breite verjüngender und in der Dicke nur geringfügig abnehmender Schaft (12) mit integriertem Hals (17) weist Fensteröffnungen (18,20) und eine eingeschraubte Schraubspindel (38) auf, deren breitflächiger Gewindesteg (42) an beiden Breitseiten (14) aus den Fensteröffnungen (18, 20) vorsteht. Dieser Gewindesteg (42) schneidet sich formschlüssig in die Spongiosa und Corticalis des Schenkelknochens ein. Die Endoprothese (10) vermittelt eine ausschließlich proximale Krafteinleitung in den Schenkelknochen, während der distale Bereich des Schaftes (12) im Knochenkanal fast unbelastet ist. A shaft (12) with an integrated neck (17) that tapers in width towards the distal end and only slightly decreases in thickness has window openings (18, 20) and a screwed-in screw spindle (38), the wide-area thread web (42) of which is on both Broad sides (14) protrudes from the window openings (18, 20). This thread web (42) cuts into the cancellous bone and cortical bone of the femur in a form-fitting manner. The endoprosthesis (10) transmits only proximal force into the femur, while the distal area of the shaft (12) in the bone canal is almost unloaded.
