    摘要： Surgical application, holding, fixing and/or fastening element with a shaft section that is elongated in at least certain sections, for example hip endoprosthesis (10) with a shaft (12) to be secured in a medullary channel of the femur of a patient, pins or bone screws for pinning fractures and/or fixing the position of bone fragments after bone surgery. The elongated shaft section includes a through bore (20) extending essentially in the longitudinal direction of the shaft section (12) and being open-ended on at least one end for introducing a flowable mass that hardens or sets after introduction, and at least one through opening (22) that connects the through bore with the outside of the shaft section. An elongated sleeve-like or tubular distribution element (24) which at least partially contacts the wall of the through bore (20) and which is moveable and/or rotatable in the through bore, is arranged in the through bore (20). The distribution element (24) is provided with at least one through opening (26) which can be aligned or moved out of alignment by moving and/or rotating the distribution element (24) relative to a respective one of the through openings (22) in the shaft section (12).

    摘要： The present invention relates to an orthopedic fastener for fixing an implant, suture, or tissue to a bone. The fastener comprises a blind rivet and a closing element. The blind rivet includes a head at a proximal end, a shank connected to the head, and an anchoring portion near a distal end. A bore extends through the head and shank from the proximal end to the distal end and the bore has a polygonal cross-section through the anchoring portion. The closing element has a body with an outer surface and is configured and dimensioned to be received in the anchoring portion. The outer surface of at least a portion of the closing element distal end has a polygonal cross-section flaring along the longitudinal axis toward the closing element distal end. The anchoring portion of the blind rivet severs into a plurality of anchoring legs when the closing element is pulled in the bore toward the blind rivet proximal end to thereby prevent rotation of the fastener.

    摘要： Apparatus and method are disclosed for maintaining the proper positioning of an implant (310, 504) within a prepared bone cavity (312) during cement injection and curing. First stabilization means (340, 480), implantable within the bone cavity, minimize lateral movement of the implant distal end, while second stabilization means (330, 334, 406, 404), physically separate from the first stabilization means (340, 480), minimize both the lateral movement of the implant proximal end and the rotational movement of the implant overall. In the preferred embodiment, the second stabilization means (330, 334) includes an aperture cap (334) removable securable to the end of a prepared bone. This cap (334), preferably further includes first and second ports (322, 336) associated, respectively, with cement injection and cement over-pressurization. In an alterative embodiment, the second stabilization means (406, 404) includes a manually operated mechanism enabling (404) the implant (504) to be temporarily, yet rigidly, secured thereto in accordance with a desired orientation, preferably affording adjustments along multiple degrees of freedom prior to the rigid securement thereof.
