摘要： The invention relates to a surgical bone screw comprising a shaft which has a bone thread and comprising a blocking means for interacting with a bone plate or for directly anchoring in the bone, in particular in the cortical bone. The surgical bone screw also comprises a screw head which has a rotationally symmetrical enveloping contour. The blocking means has a rib structure with at least one flank structure portion extending in the circumferential direction. According to the invention, the lateral surface of the enveloping contour has a constant or stepped concave progression, and the rib structure flank portion which extends in the circumferential direction is interrupted at least once in the circumferential direction, in particular multiple times, such that at least one elevation, in particular a plurality of elevations which are spaced in the circumferential direction, is produced in order to interact with the bone plate or with the bone in a blocking manner.

摘要： The present invention generally provides implantable articles and methods of forming implantable articles from a crosslinked ultrahigh molecular weight polyethylene (“UHMWPE”) blend stabilized with Vitamin E. The crosslinked UHMWPE blend may be prepared by combining the UHMWPE material and vitamin E prior to irradiating the UHMWPE blend with electron beam radiation at a sufficient radiation dose rate to induce crosslinking. The crosslinked UHMWPE blend may be incorporated into a variety of implants, and in particular, into endoprosthetic joint replacements.

摘要： A dynamic stabilization system for stabilizing a vertebral segment of a spine. The system includes a first vertebral anchor, a second vertebral anchor and a cord. The system may also include a spacer positioned between the first and second vertebral anchor through which the cord extends. The first vertebral anchor is configured to be secured to a first vertebra and the second vertebral anchor is configured to be secured to a second vertebra. The cord is extendable from the first vertebral anchor to the second vertebral anchor. The cord has a variable stiffness through a range of displacement, wherein the stiffness of the cord increases as an applied tensile force on the cord is increased.
