摘要： A plug for stopping the flow of bone cement in a bone channel, such as the intramedullary bone canal, or a previously prepared channel, includes an actuator and a number of flexible beams extending around the bone plug. The actuator is removably attached to a rod within an insertion tool used to deploy the bone plug at a predetermined location within the channel. Within the tool, the rod is pulled to move the actuator into a position applying a compressive force to act between the ends of each of the flexible beams. This compressive force causes each beam to buckle outward, into contact with the channel. The rod is then released from the actuator, and the tool is withrawn from the channel so that bone cement can be applied to hold a prosthesis in place within the channel in a proximal direction from the bone plug.

摘要： A plug for stopping the flow of bone cement in a channel within bone includes an elastomeric inflatable structure protected from bone fragments and sharp edges by a shield extending around the inflatable structure. The shield may be formed as two or more coaxial structures having flexible members extending between opposite ends, with flexible members from an inner such structure curving outward to lie between adjacent flexible members from an outer such structure as the inflatable structure is inflated. The core is also removably connected to an insertion tool, with passageways in the insertion tool and in the core being used to insert a fluid into the inflatable structure. A valve extends as a sleeve around the core, and over the passageway, allowing fluid to flow into the inflatable structure, but preventing it from flowing out of the inflatable structure.

摘要： A head component for use in a prosthetic joint such as a hip joint. The head has a body adapted to engage a natural acetabulum or a prosthetic acetabular cup component. The head has a recess with a resilient sleeve located therein adapted to engage the trunnion of a prosthetic stem component with which it is to be used. The sleeve material is more deformable than the trunnion material and can deform under sufficient force to absorb any unevenness in the trunnion surface.

摘要： A prosthetic implant cement deflector is provided for use in prosthetic surgery when employing an implant in the form of a cannulated phantom or trial prosthesis in combination with a cannulated or cannulated surgical prosthesis or a cannulated prosthesis without a phantom prosthesis. Each cannulated phantom prosthesis or cannulated prosthesis has an insert portion for location in a bone canal and a cannulation bore extending through the insert portion to receive a guide wire. The phantom includes at least one cement deflector element adapted to slide in sealing engagement on the guide wire and which can act to seal the interface between the guide wire and the surface of the distal end of the cannulation bore. The sheath used with the implant has a preformed unperforated sheath adapted to extend over the insert portion of the implant from its distal end to a position at or adjacent to its proximal end.

摘要： A plug for insertion into a bone canal is disclosed. The plug comprises an elongate central body of substantially constant cross section carrying at least four radially extending flanges of substantially equal shape and size. The flanges form solid, disk-like structures, free of cuts and are axially spaced along the central axis of the body, such that they extend in substantially parallel planes. The plug is made of a copolymer of a polyalkylene glycol terephthalate and an aromatic polyester.

摘要： Apparatus and methods are disposed for maintaining the proper positioning of a prosthetic implant having proximal and distal ends within a prepared bone cavity during cement injection and curing. First stabilization means, implantable within the bone cavity, minimize lateral movement of the distal end of the implant, while second stabilization means, physically separate from the means for minimizing lateral movement of the distal end of the implant, minimize both the lateral movement of the proximal end of the implant and the rotational movement of the implant overall. In the preferred embodiment, the second stabilization means includes an apertured cap removably securable to the end of a bone having the prepared cavity through which the implant is inserted and held in place. This cap, which may either be entirely rigid or include a pliable membrane in the vicinity of the aperture, preferably further includes a first port associated with cement injection and a second port associated with cement over-pressurization. In an alternative embodiment, the second stabilization means includes a manually operated mechanism enabling the implant to be temporarily yet rigidly secured thereto in accordance with a desired orientation, preferably affording adjustments along multiple degrees of freedom prior to the rigid securement thereof.

摘要： Methods and apparatus for forming one or more trans-sacral axial instrumentation/fusion (TASIF) axial bore through vertebral bodies in general alignment with a visualized, anterior or posterior axial instrumentation/fusion line (AAIFL or PAIFL) in a minimally invasive, low trauma, manner and providing a therapy to the spine employing the axial bore. Anterior or posterior starting positions aligned with the AAIFL or PAIFL are accessed through respective anterior and posterior tracts. Curved or relatively straight anterior and curved posterior TASIF axial bores are formed from the anterior and posterior starting positions. The therapies performed through the TASIF axial bores include discoscopy, full and partial discectomy, vertebroplasty, balloon-assisted vertebroplasty, drug delivery, electrical stimulation and various forms of spinal disc cavity augmentation, spinal disc replacement, fusion of spinal motion segments and implantation of radioactive seeds. Axial spinal implants and bone growth materials can be placed into single or multiple parallel or diverging TASIF axial bores to fuse two or more vertebrae, or distract or shock absorb two or more vertebrae.
