ABSTRACT:
The present invention relates to a screw implant (1) for insertion into a bore hole (50) arranged in bone tissue, said implant having a cancellous portion (3), and a cortical portion (2) having an axial length such that, when installed in the bore hole (50), the engagement of said cortical portion (2) with the bone tissue will generally be confined to the cortical bone tissue layer (52). Said cortical portion (2) presents an outer surface which is threaded for accomplishing said engagement, and has an outer design such that, when being screwed into said bore hole under action of a screwing torque, said cortical portion (2) acts so as to increase the compression of the cortical bone tissue only, in essentially radial directions of the implant, resulting in a distinct increase of the screwing torque needed for screwing the implant (1). Said increase is usable as an indication that the implant (1) is in place or nearly in place in the bore hole.The invention also relates to an arrangement comprising an implant and a bore hole, and a method for insertion of an implant into a bore hole.
