BONE TISSUE ENGINEERING BY EX VIVO STEM CELLS ONGROWTH INTO THREE-DIMENSIONAL TRABECULAR METAL
20180008747 · 2018-01-11 ·

Adult autologous stem cells cultured on a porous, three-dimensional tissue scaffold-implant for bone regeneration by the use of a hyaluronan and/or dexamethasone to accelerate bone healing alone or in combination with recombinant growth factors or transfected osteogenic genes. The scaffold-implant may be machined into a custom-shaped three-dimensional cell culture system for support of cell growth, reservoir for peptides, recombinant growth factors, cytokines and antineoplastic drugs in the presence of a hyaluronan and/or dexamethasone alone or in combination with growth factors or transfected osteogenic genes, to be assembled ex vivo in a tissue incubator for implantation into bone tissue.

MODULAR PROSTHESIS FOR AT LEAST PARTIAL REPLACEMENT OF A TUBULAR BONE ADJOINING A JOINT

Modular endoprosthesis for at least partial replacement of a tubular bone, comprising, as module components, a stem for insertion into a bone cavity of the tubular bone, and an end piece comprising a support body with a neck part arranged on the medial aspect thereof. Said 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, by means of the location-specific direct adhesion of the muscle. It is thus possible to achieve quicker and reliable mobilization of the patient, and this with a reduced risk of complications.

Laser-produced porous surface

The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.

An orthopedic implant can comprise a structural body, a plug and a frangible connection. The structural body can comprise a first surface, a second surface opposing the first surface, and a through-bore extending from the first surface to the second surface. The through-bore can have a bore surface. The structural body can be formed of a porous material. The plug can be disposed in the through-bore. The frangible connection can link the bore surface and the plug. A method of manufacturing an orthopedic implant can comprise producing a porous structural body having a port, producing a plug for positioning in the port, and producing a plurality of frangible crosspieces within the port to connect the plug to the structural body.
