  • Publication number: 20220226121
    Abstract: Hip joint implant for fastening to a pelvic bone (9), with a support body which has a socket (6) and whose convex outer face is designed to bear on the pelvic bone (9) and which, on its concave inner face, has a receiving seat for a pelvis-side bearing that is designed to receive a joint head of a femoral component of a hip prosthesis, and with outwardly directed flat fastening brackets (2, 3) which are arranged at the edge region of the socket (6) and are each provided with at least one receiving seat for a fastening means. The fastening brackets (2, 3) are made of a reshapeable biocompatible material and are connected to the socket (6) via a non-releasable cohesive bond (7), wherein the socket (6) is made of another, stiffer biocompatible material. A high degree of robustness of the socket (6) is thus combined with what is, by virtue of the reshapeability, an improved adaptation to the anatomical conditions of the respective pelvic bone.

  • Patent number: 9676026
    Abstract: A method for manufacturing a bioresorbable implant, wherein a magnesium alloy is formed into an implant. A melt is pressed into a die and gases in the die induce turbulence in the inflowing melt, thereby enclosing gas, so that the porous implant is formed with a porosity, which increases from outside inwardly. The surface of the implant is substantially free from open pores.

  • Publication number: 20150201983
    Abstract: The aim of the invention is to enlarge the possibilities of use of conventional bone plates and increase their flexibility of manipulation. To this end, the invention proposes a bone plate comprising a bottom side that is to rest against the bone and an upper side opposite to the bone as well as a plurality of holes located preferably along the longitudinal axis of the plate, through which bone screws can be inserted to be anchored to a bone. At least one of these holes is a continuous oblong hole comprising a longitudinal axis running in the direction of the longitudinal axis of the plate. A retaining structure, such as thread flights, is provided in a partial area of the lateral side of the oblong hole, said thread flights, when see in a direction transversal to the plane of the upper side, are arranged only over a part of the depth of the oblong hole.

  • Patent number: 6238436
    Abstract: A modular artificial hip joint includes a head part and at least one shaft part. The shaft part, which can be driven into the bone and forms the distal region, is connected to the distal end of the head part by insertion, preferably by means of an insert cone. A first screw or tie rod, guided through an axial bore in the head part, can be screwed into the threaded bore in the shaft part. In order to guide a second screw for separating the conical insert connection between the individual components of the artificial joint, the bore in the head part is threaded and has a diameter which is greater than the diameter of the threaded bore in the shank part.

  • Patent number: 6136035
    Abstract: A modular hip joint prosthesis is assembled from a head section having a connection for the ball of the joint and from a shaft section. The shaft section is joined by a insert connection to the head section, and provision is made for fixing the insert connection. The insert connection is situated in the region of Shenton's arc. The respective contours, in longitudinal section, of the head and shaft sections in the region of the connection merge smoothly, without any substantial change in direction, irrespective of the relative mutual alignments of the sections at any given time, with the exception of a gap in the immediate vicinity of the connection.
