An assembly for use in an external fixator, structured to adjustably interconnect at least one or a plurality of bone fixation rods to a pin clamp comprising a base structurally adapted for movable, adjustable interconnection between the pin clamp and the one or more rod clamps. An elongate support shaft is movable with the base and movably connected thereto and at least one or alternatively a plurality of rod clamps are mounted on the support shaft. Each of the plurality of one or more rod clamps is structurally adapted to secure a different fixation rod to the support shaft. The one or more rod clamps are movably connected and adjustably positioned on the support shaft in adjacent relation to one another. The base, the support shaft and one or more rod clamps are movably interconnected relative to one another to define a substantially universal disposition of said plurality of rod clamps relative to the pin clamp.

Female polyaxial joints for connecting a strut to a support frame of an external fixation device are described having a ball socket and a ball member. The ball member includes a spherical portion and a ball member shaft extending from the spherical portion. At least one aperture is positioned on the ball member and traverses through at least a portion of the ball member shaft. An internal surface of the ball member shaft may be threaded and configured to receive a threaded connector.

A clamping device of an external fixation system that has a jaw set with a passage at one end configured to hold an element from a first range of sizes and a second passage configured to hold an element from a different range of sizes. The jaw set includes a first jaw, a second jaw, and a slider interposed between the first and second jaws that moves to a first position when the first element is located in the first passage and to a second position when the second element is located in the second passage.

A device includes a plurality of rings. Each ring has a first face, a second face, and at least one slot defined by first and second interior edges of the ring on opposing sides of the slot. The at least one slot penetrates from the first face to the second face. The first face of each ring has a first recess adjacent the slot on the first edge and a second recess adjacent the slot on the second edge. A plurality of posts join each one of the plurality of rings to an adjacent one of the plurality of rings.

A plurality of three-dimensional fixator graphical representations may include graphical indications of a strut swap range. A plurality of replaced strut graphical representations may change from a first rendering state in a swap start fixator graphical representation to a second rendering state in a swap end fixator graphical representation. A plurality of replacement graphical representations may change from the second rendering state in the swap start fixator graphical representation to the first rendering state in the swap end fixator graphical representation. In some examples, the plurality of replaced strut graphical representations may gradually fade out from a swap start stage to a swap end stage, and the plurality of replacement strut graphical representations may gradually fade in from a swap start stage to a swap end stage. Additionally, a treatment plan including at least one interfamily strut swap may be generated for manipulating a fixator to correct a deformity.

A fixation system for immobilizing a skeletal structure is provided. It includes an internal fixation system having a rod-plate subsystem, a shaft subsystem, and a midfoot plate subsystem. It further includes an external fixation system adapted to connect to the internal fixation system and having a sole that provides a weight-bearing platform underneath a patient's foot to enable a patient to walk with the fixation system.

External fixator assemblies, systems, and methods thereof. An external fixator system may include a plurality of fixator assemblies configured to connect a plurality of pins, for example, positioned on opposite sides of a fractured bone, with one more rods. The fixator assemblies may include a plurality of clamp assemblies that are configured to clamp onto the rods. A distractor/compression instrument is used to adjust the location of a clamp assembly along the length of its rod.
