摘要： A system for fixation of bone, including a bone plate with an opening comprising threads made of a first material and a fastener with a head at least partially comprising a polymeric material that is softer than the first material. In some embodiments, when the fastener is inserted into the first opening, the threads of the first opening form threads in the polymeric material on the head of the fastener and secure the fastener in place at one of a plurality of possible angles within the first opening. The first opening additionally accepts a fastener with a substantially spherical head for compression of a fracture, or a fastener with a threaded head that engages with the threads of the threaded opening. In some embodiments the first opening includes a substantially frustoconical-shaped top portion. In other embodiments there may be a second opening that is either non-threaded or comprises a plurality of protruding fins.

摘要： Systems, devices and methods are disclosed for treating fractures. The systems, devices and methods may include one or both of an implant, such as an intramedullary nail, and a fastening assembly, such as a lag screw and compression screw assembly. The implant in some embodiments has a proximal section with a transverse aperture and a cross-section that may be shaped to more accurately conform to the anatomical shape of cortical bone and to provide additional strength and robustness in its lateral portions, preferably without requiring significant additional material. The fastening assembly may be received to slide, in a controlled way, in the transverse aperture of the implant. In some embodiments, the engaging member and the compression device are configured so that the compression device interacts with a portion of the implant and a portion of the engaging member to enable controlled movement between the first and second bone fragments. This configuration is useful for, among other things, compressing a fracture.

摘要： A bone screw apparatus and method of implantation provides a bone screw having an elongated shaft of an oversized length with proximal and distal end portions. The distal end portion of the shaft has a cutting head. The proximal end portion of the shaft is sized and shaped to accept a driver tool, such as a drill chuck. The shaft is externally threaded along a majority of its length. A pair of opposed longitudinally extending circumferentially spaced flat surfaces are provided along the shaft. A removable head with a central opening enables the head to slide along the shaft proximally to distally. A ratcheting mechanism prevents movement of the head along the shaft in but one direction. A central opening of the head is shaped to conform to the shaped surfaces of the shaft, so that the head and shaft can be rotated as a unit by engaging and rotating the head. The tool receptive surface portion of the head includes intersecting external surfaces of the head spaced radially away from the shaft during use.
