Abstract: A ratcheting strut comprising: (a) a ratchet box including a through passage; (b) a first tube sized to extend at least partially through the passage, the first tube including teeth that engage corresponding teeth of the ratchet box; (c) a second tube mounted to the ratchet box in parallel with the first tube, the second tube operatively coupled to a second fixation adapter; and, (d) a threaded rod operatively coupled to a nut and a first fixation adapter, the threaded rod repositionably mounted to the first tube, where the nut is operatively coupled and repositionable with respect to the first tube.

Abstract: A clamping assembly for an external fixation system, comprising a clamp body having an opening for receiving a bone fixation member; a pivotably rotatable locking arm associated with the clamp body, the locking arm being configured to provisionally hold the bone fixation member inside the opening of the clamp body; and a cam arm coupled to the locking arm, the cam arm being pivotably rotatable towards the clamp body to definitively hold the bone fixation member inside the opening of the clamp body.

Abstract: A clamping assembly for an external fixation system, comprising a clamp body having an opening for receiving a bone fixation member; a pivotably rotatable locking arm associated with the clamp body, the locking arm being configured to provisionally hold the bone fixation member inside the opening of the clamp body; and a can arm coupled to the locking arm, the cam arm being pivotably rotatable towards the clamp body to definitively hold the bone fixation member inside the opening of the clamp body.

Abstract: Disclosed is an external fixation system. The external fixation system can comprise a ring frame, a strut, and a pivot housing connecting the strut to the ring frame. The pivot housing can comprise a first compression member, a second compression member, and a post assembly. The first compression member can be attached to the ring frame. The second compression member can be spaced from the first compression member and attached to the first compression member. The post assembly can be connected to the strut via an attachment post protruding from a spherical component and passing through the first compression member. The spherical component can be compressed between the first compression member and the second compression member to retain the post assembly in a fixed position.

Abstract: An orthopedic device includes a targeting member, an elongated guiding member, and an adjustment member. The targeting member has an elongated body along a first longitudinal axis and can be coupled to an intramedullary implant such that the first longitudinal axis is parallel to the intramedullary implant. The targeting member includes a first bore extending along a second longitudinal axis t1hrough the elongated body, the first bore having a cross-section elongated in the direction of the first longitudinal axis. The first and second longitudinal axes define a first plane. The elongated guiding member passes through the first bore and is pivotable relative to the first longitudinal axis. The adjustment member is coupled to the elongated body and operable to change an orientation of the guiding member relative to the first longitudinal axis in the first plane.

Abstract: A tensioner for tensioning a wire/cable coupled to an external orthopedic device. The tensioner can include a housing, an outer sleeve movable relative to the housing, a movable tension actuator handle operable to move the outer sleeve relative to the housing, and a plurality of movable jaws supported in the outer sleeve. The jaws can move between an open position for receiving the wire/cable and a closed position for gripping the wire/cable when the tension actuator handle is operated.

Abstract: An external fixation system for a joint having a first and second bone and defining an anatomical axis of rotation is provided. The fixation system can include a proximal frame couplable to the first bone and a distal frame couplable to the second bone. A first connector can include a first member pivotally coupled to a second member at a first pivot axis. A second connector can include a third member pivotally coupled to a fourth member at a second pivot axis. The first and second connectors are mountable between the proximal and distal frames at a location such that the first and second pivot axes are coaxial with the anatomical axis of rotation.

Abstract: An external fixation system for a bone and associated method. The fixation system includes a proximal frame defining a continuous proximal boundary, a distal frame defining a continuous distal boundary, and at least one frame connector configured for interconnecting the proximal and distal frames at any position along at least one of the proximal and distal boundaries.
