  • Patent number: 10751099
    Abstract: A bone plate has a through-hole that extends from an upper side to a bone-side underside of the bone plate. A lip is formed in the through-hole, which lip projects from the lateral surface of the through-hole and extends in the circumferential direction of the through-hole. The lip extends over part of the circumference of the through-hole. In a circumferential section of at least 120° that lies opposite the lip, the lateral surface is free of a lip. Material is reshaped only to a lesser extent compared to a lip that extends over the entire circumference of the through-hole. The risk of complications occurring due to deposited particles is reduced.

  • Patent number: 9775658
    Abstract: The invention relates to a bone plate system with a bone plate, a pressure plate, and a bone screw. The bone plate comprises a through-hole, said through-hole having a seat surface with a variable angle for the bone screw. In the connected state of the system, the bone screw is inserted into the through-hole. The head of the bone screw is enclosed between the bone plate and the pressure plate. The pressure plate is fixed to the bone plate via a screw connection which has two securing screws. The axes of the securing screws spread apart such that the distance between the axes of the securing screws increases in the screw-in direction. The head of the bone screw is thereby reliably fixed between the pressure plate and the bone plate.

  • Patent number: 9681901
    Abstract: An osteosynthesis system for treating fractures of tubular bones includes an intramedullary nail with an elongated nail body consisting of a hard metal material with two end sections and a middle section therebetween that has at least one transverse screw hole close to the end for screwing in at least one bone screw into each end section. The nail body is solid or has a through-channel arranged in the center in the cross-section of the nail body. In the middle section at least two transverse one-sided screw holes are placed proximate to a fracture. Screw holes are formed as inlays made out of soft metal material securely joined to the nail body, and bone screws with an initial thread consisting of hard metal material that can be screwed into the bone and screw holes while forming threads.

  • Publication number: 20160015439
    Abstract: The invention relates to a bone screw for fixing a connection support to a bone. The bone screw comprises a screw head, which has a head thread for producing a threaded connection to the connection support. The bone screw further comprises a shank, which has a bone thread for engaging in the bone substance. Between the screw head and the shank, the bone screw has a transition area. The bone screw has a coating on its surface. According to the invention, the coating has a greater thickness in the area of the shank than in the area of the screw head. The coating according to the invention leads to an improved connecting strength between screw and connection support.

  • Publication number: 20140330320
    Abstract: The application relates to a bone plate with a through-hole that extends from an upper face of the bone plate to a bone-side lower face thereof. A lip is formed in the through-hole, protrudes from the interior surface of the through-hole and extends in the circumferential direction of the through-hole. The lip has a plurality of circumferential portions in which the lip surface directed towards the upper face of the bone plate is designed as an inclined surface that slopes in the circumferential direction, wherein the lip surface has a front inclination face and a rear inclination face, and wherein the front inclination face and the rear inclination face have an opposite inclination in the circumferential direction. The bone plate has the advantage that a bone screw can easily cut into the lip.

  • Publication number: 20140207194
    Abstract: A system comprises a bone plate and a bone screw. The bone plate is provided with a through-hole, which extends from an upper face to a bone-side lower face of the bone plate. A lip is formed in the through-hole, which lip protrudes from the curved surface of the through-hole and extends in the circumferential direction of the through-hole. The bone screw has a head thread, which is designed to reshape the lip in the through-hole in order to form a threaded connection. The lip has a step arranged between the curved surface of the through-hole and a central region of the lip, which step extends along the lip. The system has the advantage that a bone screw can easily cut into the lip.

  • Patent number: 8460347
    Abstract: The subject matter of the invention is a load carrier for a bone fixation system, with a locally varying material strength with unchanging material elasticity, and a method for producing such a load carrier. The load carrier, matched in view of the load flow acting on the fixation system, can also be used in critical anatomical regions, e.g. for hand implants.

  • Patent number: 8287542
    Abstract: The repositioning and fixation system according to the invention comprises at least two bone plates that are designed to be interconnected. Each bone plate is provided with a connector element for connection to another bone plate. The connector element of a first bone plate comprises a plurality of projections. The connector element of a second bone plate comprises an opening. In a first connection state, the projections engage in the opening and produce a hinge-type connection between the first bone plate and the second bone plate. In a second connection state, the projections are tensioned and produce a rigid connection between the first bone plate and the second bone plate. With the repositioning and fixation system according to the invention, bone fragments secured to the bone plates can be repositioned by pivoting of the bone plates. Once the bone fragments have been brought to their final position, the projections can be tensioned in such a way that the bone plates are rigidly interconnected.

  • Publication number: 20100137919
    Abstract: The invention relates to a bone screw with a shaft that defines a longitudinal axis and with a head that is configured as a thickened portion, said shaft and head being threaded. The thread of the shaft (bone thread) merges in an uninterrupted manner into the thread on the flared area of the head adjoining the shaft. As a result, part of the threaded head lies in the osseous tissue, giving a larger contact surface between bone screw and bone and improving the distribution and transmission of the loads and forces.

  • Publication number: 20100136080
    Abstract: The subject matter of the invention is a material depot which dispenses an antibacterial active ingredient material into a human or animal body via the surface of the depot. The surface of the material depot is larger than the envelope of the material depot. The increased surface of the material depot effects a higher level of the antibacterial active ingredient material at the location of the implant and permits effective destruction in situ of both sensitive pathological germs and partially resistant germs.
