摘要:
This invention is directed to an orthopedic screw with a screw head, a screw body with distal tip, a shank with an enlarged diameter at the trailing end and a thread extending radially outward from the shank, and an internal capture surface. This invention also provides a system for use in an orthopedic surgical procedure including the screw, an orthopedic implant adapted to be secured in a patient with the screw, and a driver capable of engaging the internal capture of the screw. The invention further provides methods of using the screw, the system, and the screw and driver assembly.

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.

A digital multimeter displays a miniature version of a live actual reading of the multimeter. The miniature version typically appears after a larger version of the live actual reading is displaced by other display elements. The miniature version of the live actual reading may be accompanied by a warning icon or other graphical symbol to alert a user of a potentially hazardous electrical condition.

Methods, systems, and devices according to this invention provide drill guides for optimal placement of fixation elements, such as half pins, into a patient's bone. According to one embodiment, a collar frame (202) with a collar adapted (204) to receive a bar (270) of an orthopedic external fixation system such that the collar may be moved linearly or rotationally about the bar is coupled to a guide frame (224) including a bore (232) through which a fixation element (266) of the external fixation system may be inserted. The coupling between the collar frame and the guide frame allows for them to rotate about at least one axis relative to each other. In one embodiment, the collar frame and the guide frame may rotate about three axes relative to each other.

摘要:
An external fixation system having a fixation component (20) comprising: a) a first capture member (24) adapted to capture a second element (26) of an orthopedic fixation system; and (b) a second capture member (22) adapted to capture a second element (28) of an orthopedic fixation system and coupled to the first capture member such that the coupling (86,94,110) allows the first capture member and the second capture member to rotate about three axes relative to each other element and move along that axis; wherein the coupling is adapted to secure the first and the second capture members from rotation with an activation (100); and wherein the second capture member is adapted to capture the second element by snapping onto the second element from substantially perpendicular to longitudinal axis of the second element

A goal for a soccer skills-enhancing game is configured for practicing a chip shot, and includes an upper frame defining an aperture for receiving a ball vertically downward therethrough, and a lower frame for resting on a playing surface. Support members are operatively connected between the upper and lower frames to form a vertical space therebetween. A see-through wrap of fabric or plastic is wrapped around an outer side of the support members, encircling the vertical space to form the vertically-disposed goal. The goal preferably includes a bag, or net, attached to and held in an open position around the upper frame for catching a ball received through the aperture. The upper and lower frames may be hexagonally shaped. A game apparatus includes at least one goal and a ball. A method for playing the game includes scoring points for chipping or deflecting the ball into the bag.

A vibration data collection and rotating machinery fault diagnostic instrument includes a machine setup engine, a measurement engine, a diagnostic engine, a measurement user interface module, a machine setup user interface module, and a diagnostic user interface module. The machine setup engine requests and receives parameters about the machinery through the machine setup user interface module. The measurement engine requests and receives sensor placement locations through the measurement user interface module and keeps track of locations that have been measured and locations that still need to be measured. The diagnostic engine diagnoses machinery faults and presents the information to the user through the diagnostic user interface module using an intuitive graphical severity scale.
