Abstract: A fastener assembly can include a proximal fastener member, a distal fastener member and an internal fastener member. The proximal fastener can include a fastener head and an internal wall defining an anti-rotation feature. The distal fastener can include a proximal end defining an internal bore and an external anti-rotation feature, and a distal end defining a bone anchor. The internal fastener can be positioned in the cannulated proximal fastener and threadably coupled to the distal fastener such that the proximal end of the distal fastener is telescopically received in a distal end of the proximal fastener. Rotation of the internal fastener in a first rotational direction can telescopically retract the distal fastener into the proximal fastener so as to be adapted to compress a bone fracture. Rotation of the internal fastener in an opposite rotational direction can extend the distal fastener relative to the proximal fastener.

Abstract: Methods, systems and apparatuses including an assembly for changing an orientation of a first portion of a femur relative to a second portion of the femur are disclosed. The assembly can include an intramedullary nail and a jig. The intramedullary nail can be insertable into an intramedullary canal of both the first portion of the femur and the second portion of the femur. The intramedullary nail can have a first section disposed between a proximal end and a distal end thereof. The first section can have at least one surface that is angled relative to an axis of the intramedullary nail. The jig can be coupled to and rotatable about the intramedullary nail to change a rotational position of the first portion of the femur relative to the second portion of the femur.

Abstract: A dual reconstructive wire system for use with an anatomy can include a first guide wire, a second guide wire, a first guide instrument, a first cannulated insertion instrument, and a second cannulated insertion instrument. The first guide wire can pass through the first cannulated insertion instrument such that a first end and a second end of the first guide wire extends beyond the first end and the second end, respectively of the first cannulated insertion instrument. The second guide wire can pass through the second cannulation insertion instrument such that a first end and a second end of the second guide wire extends beyond the first end and the second end, respectively of the second cannulated insertion instrument.

Abstract: An orthopedic device can include an intramedullary nail with a longitudinal bore, first and second bone fasteners with sleeves and a cannulated movable member received within the longitudinal bore. The movable member defines first and second guiding bores for receiving respectively the first and second fasteners. Each of the first and second guiding bores includes a pair of opposing deformable elongated strips. Each pair of strips can engage the sleeve of a corresponding bone fastener.

Abstract: An orthopedic device is provided. The orthopedic device can include an intramedullary implant defining a longitudinal bore along a longitudinal axis. The intramedullary implant can define at least one bore formed along an axis for receipt of a fastener. The orthopedic device can include a fixation device receivable within the longitudinal bore. The fixation device can have at least one guiding bore formed along a guiding axis transverse to the longitudinal axis. The orthopedic device can include at least one collet received within the at least one guiding bore for positioning and locking the fastener at a variable angle relative to the guiding axis of the fixation device and the axis of the intramedullary implant.

Abstract: A planar balun including first and second spaced parallel elongated conductors on one surface of a ceramic, plastic, polymer, synthetic fiber or a composite substrate and a third elongated conductor on a second surface of the substrate opposite from the first and second conductors. The spacing from an outer edge of each of the first and second conductors to an outer edge of the third conductor being greater than the thickness of the ceramic substrate, and the spacing between the two parallel elongated conductors being greater than ##EQU1## The substrate is mounted on a metallic support plate which provides a ground plane spaced from the third conductor by a distance t2 in an atmosphere comprising air with the distance t2 being greater than ##EQU2## An input of the balun is at one end of the first and second conductors and an output of the balun is at the other end of the first and second conductors.
