Abstract: An augment device includes a hollow sleeve surrounding a channel extending through the hollow sleeve from a top to a bottom of the hollow sleeve, the hollow sleeve comprising a wall having an inner face and an outer face. The hollow sleeve includes at least one bending joint, the bending joint being configured for compressing the channel. Thereby the hollow sleeve may be compressed under an external force, leading to a decreased circumference and width of the hollow sleeve. This leads to a gap between the perimeter of the augment device and surrounding bone material, breaking any connections. By virtue of this, a much-facilitated removal of the augment device can be achieved. Further, an extraction tool includes grippers for engaging and compressing the augment device, and further instruments, particularly a jig, for achieving an effective removal.

Abstract: An extracorporeally length-adjustable implant system comprises an implant component to be fastened to a bone to be lengthened and an adjustment device with two fastening parts that are displaceable relative to one another, each of which is intended for arrangement at a part of the bone to be lengthened, wherein the adjustment device is able to distract the two fastening parts and comprises a drive element with a permanent magnet arranged in rotationally fashion and a mechanism which converts a rotational movement of the permanent magnet into a distracting longitudinal movement of the adjustment device; and an extracorporeal drive unit for the drive element of the implant component. The extracorporeal drive unit comprises a rotatably mounted extracorporeal magnetic ring with an interior to receive the bone to be lengthened with the adjustment device, and an actuation device to rotate the extracorporeal magnetic ring in the ring plane thereof.

Abstract: Graft for a bone defect, in particular a tibial head graft for a knee-joint endoprosthesis. It comprises a sleeve-like inner body (2) for implantation at one end of a long bone (99). An outer face of the inner body (2) is designed as a bone contact face (20) for bearing on the surrounding bone margin (97). According to the invention, an outer shell piece (3) is provided which, as a bone replacement piece, is doubled onto the outside of the inner body (2) for filling a defect at the cortical bone margin (97) and is not dimensioned peripherally, such that, in the circumferential direction, it covers only a part of the outer circumference of the inner body (2). The doubled outer shell piece (3) forms a filler piece for a bone defect (bone window 96) at the bone end. Closure of the bone window (96) is achieved, and unwanted contact between the graft and surrounding soft-tissue parts is avoided. Moreover, the graft is thus also supported in the region of the bone window (96).

Abstract: Modular endoprosthesis for at least partial replacement of a tubular bone, including, as module components, a stem for insertion into a bone cavity of the tubular bone, and an end piece including a support body with a neck part arranged on the medial aspect thereof. The module components being able to be coupled to each other and released from each other along a longitudinal axis of the shaft. The end piece has at least two different surface configurations on its support body, namely a closed surface (6?) on a medial aspect, and a porous configuration of the surface on the opposite, lateral aspect. The latter permits and positions the adhesion of muscle tissue, specifically without suturing. The muscle trauma caused by suturing, and the peak loads that occur at the respective suture points, can thus be avoided by virtue of the invention.

Abstract: The invention relates to a connecting sleeve for anchoring shafts of two oppositely arranged prostheses, preferably on an elongate bone such as a femur or humerus. The reinforcing sleeve comprises two receiving bushes for one prosthesis shaft each and comprises a separable coupling region arranged therebetween for connection in such a manner as to resist shear forces and rotation. According to the invention, each receiving bush has, on the side thereof facing the coupling region, one fork of a pair of forks that interact with each other, and a fitting block is arranged on a base of the fork, the lateral surfaces of which fitting block have a distance that corresponds to an inner width of the fork, and the lateral surfaces are designed to contact flanks of the fork in a planar manner, at least one fastening screw being arranged transversely through the fork. The fork connection is simpler to produce than the known wedge connection and yet is sufficiently robust.

Abstract: Hip joint implant for fastening to a pelvic bone, with a support body which has a socket and whose convex outer face is designed to bear on the pelvic bone 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 which are arranged at the edge region of the socket and are each provided with at least one receiving seat for a fastening means. The fastening brackets are made of a reshapeable biocompatible material and are connected to the socket via a non-releasable cohesive bond, wherein the socket is made of another, stiffer biocompatible material. A high degree of robustness of the socket is thus combined with what is, by virtue of the reshapeability, an improved adaptation to the anatomical conditions of the respective pelvic bone. This improves reliability of fastening, stability and long-term behavior.

Abstract: Medical implant, in particular an augment for a joint endoprosthesis, comprising a sleeve-shaped hollow body having a wall surrounding a channel in a circumferential direction. The channel extends in a longitudinal direction from a bottom to a top of the hollow body. The wall comprises at least one living hinge oriented in the longitudinal direction. The living hinge is configured for compressing the channel. The living hinge being formed by a bent slit that extends as a slit at least in a vertical and in a horizontal direction. As opposed to an ordinary linear slit, the bent, i.e., non-linear slit extends thus as a slit in two dimensions, horizontal and vertical. Thereby an increased elasticity can be realized, achieving a medical implant which has a better adjustable elasticity.
