摘要： Unicompartmental tibial components are described herein. A first unicompartmental component (10) comprises a plate (12) having a bearing surface (18) and an opposing surface (22) that is configured to be secured to a proximal end of a patient's tibia, wherein the plate further comprises an anterior end (24), an outer side (25), a posterior end (26) and an inner side (27), wherein a mediolateral width W of the plate is defined between the outer and inner sides, and a longitudinal anteroposterior axis (28) extends between the anterior and posterior ends approximately one third of the width of the plate (i.e. 1/3 W) from the lateral side, and defines a longitudinal axis length L of the plate. A first elongate peg (14) protrudes from the opposing surface in the anterior portion, the first elongate peg defining a first peg axis (32). A second elongate peg (16) protrudes from the opposing surface in the anterior portion, the second elongate peg defining a second peg axis (34). The first and second peg axes are disposed at an angle of 45-70 degrees with respect to the longitudinal anteroposterior axis and are substantially parallel to one another such that the first and second pegs protrude posteriorly as well as distally with respect to the plate. An anterior portion of the plate comprises a part of the plate defined by an anterior 60% or less of the longitudinal axis length L, whilst a posterior portion of the plate comprises a part of the plate that is defined by the remaining posterior 40% or more of the longitudinal axis length L. The posterior portion of the opposing surface is free from pegs or other fixation devices, and the first and second elongate pegs are located more than half of the mediolateral width W of the plate from an outer edge of the plate. The component is configured for cementless fixation using an interference fit. Also described is a method of installation and a tool suitable for use in installation.

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.
