Abstract: 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.

Abstract: A locking fastener for use with a bone plate. The fastener has threads on its shank to engage bone and threads on its head to engage the internal threads of the bone plate. The threads in the head may have a constant major diameter and a tapered minor diameter that creates a radial interference fit. The threads in the head may also have a variable pitch that creates an axial interference fit. The head may have a low profile to reduce soft tissue irritation.

Abstract: An external fixation system having an improved fixation component for constructing a stable, adjustable fixation system that cooperates with other systems, and methods of use thereof.

Abstract: 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 with a collar adapted to receive a bar 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 including a bore through which a fixation element 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.

Abstract: The present invention provides a device for treating fractures of a bone and methods for treating a facture, particularly fractures of the femur, that uses an intramedullary nail or a bone plate and a sliding compression fixation element. Certain features of various fixation elements described herein lessen the rotational forces applied during implantation and/or lessen the amount of bone that needs to be removed during placement of the sliding compression screw.

Abstract: 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.
