    摘要： An intraosseous device is disclosed that can be positioned to straddle a bone fracture to stabilize the fracture and provide structural support for the bone and the surrounding areas. The device includes wire assemblies that are deployable on each side of the fracture to anchor the device within the bone. For the device, an elongated tube is formed with a plurality of slots at each tube end. A central member is mounted inside the tube and moveable members are positioned inside the tube, one at each tube end. Wires connect the moveable members to the central member. A rod cooperates with each moveable member and is rotatable to draw each moveable member inwardly toward the central member. This forces each wire to bow and displace a central wire portion through a corresponding slot and into contact with the bone's inner wall to anchor the device in the bone.

    摘要： An in-bone implantable shaft for prosthetic joints or for direct skeletal attachment of external limb prostheses, comprised of a central body fitted in the zone of the bone's medullary cavity conventionally prepared for implantation, and of side elements attached to the central body and fitted in the slots specially made in the bone's walls surrounding said medullary canal; said side elements have spaces between them, arranged to be filled by bone cells to provide a natural and safe osseolocking of the shaft. A method of preparing the bone for implantation of a prosthetic shaft, comprising the steps of: placing a cylindrical guide with slots made in the longitudinal direction of said guide inside said bone's canal which is conventionally prepared for implantation; cutting said bone's walls by progressing a saw along the edges of the slots of said guide; removing the guide; fitting the shaft in the bone's canal, provided that the side elements are fitted to the slots in the bone's walls.

    摘要： An intramedullary nail for a fractured elongated bone, comprising a cannulated rod having proximal and distal ends; an outside tubular sleeve for coaxially hosting and guiding the rod; and at least a pair of shape memory elements hosted in corresponding seats at the distal end of the rod. Each shape memory element can be retractably housed in its seat in a first configuration, allowing insertion of the nail into the bone, and can project from a sleeve opening in another configuration. Pairs of transversal holes are provided in proximal portions of the rod and the sleeve. The distal pair of shape memory elements lie on an offset plane to the plane of the proximal holes and are kept in their corresponding seats by a distal cover fixed to the rod. This improves the stability of the nail in the medullary canal.

    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 system for communicating fluid to or from a bone includes an insert. The insert includes a shaft extending between proximal and distal ends of the insert, a fenestration, and an expandable portion coupled to the shaft. The shaft is cannulated along at least a portion of the shaft between the proximal and distal ends. The fenestration is disposed along the cannulated portion of the shaft. Outer surfaces of the expandable portion are configured to expand laterally outward to increase the cross-sectional area of the expandable portion orthogonal to the shaft.
