An orthopedic clamp for affixing at least two fixation members relative to each other is disclosed. The clamp includes a first clamp comprising first outer and inner jaws that define first clamping surfaces that form a first recess, and a second clamp comprising second outer and inner jaws that define second clamping surfaces that form a second recess. The clamps also include a post extending from the second outer jaw and through the second inner jaw, the first inner jaw and the first outer jaw. The post defines a clamping axis, and the second recess defines an axis that intersects the clamping axis. The clamp further includes a clamping nut threadably coupled to the post configured to exert a clamping force to the first and second clamps to fix at least one of a first fixation member within the first recess and a second fixation member within the second recess.

An external fixator system includes a proximal frame configured to restrict motion in a lower extremity of a subject, and a frame connector assembly. The proximal frame includes a first, second, and third component. The first component can support a first clamp to secure a first pin inserted within a bone extending between a foot and a knee of the lower extremity. The third component extends from a second end of the second component. The first, second and third components have longitudinal axes that are substantially coplanar. The third component includes an extension to extend over a dorsal portion of the foot of the subject and to support a second clamp to secure a second pin inserted within a bone of the foot. The frame connector assembly extends from the second component to support a third clamp to secure a third pin inserted within a third bone of the foot.

An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.

Described herein are external fixation systems for correcting bone deformities in adjacent bones or fragments thereof. The systems herein include first and second elongate tubes that translate with respect to one another via rotation of an actuation member at an end of one of the rods. At least one housing member is coupled along a length of one of the tubes. The housing member includes at least clamping portion for clamping a portion of a fixation pin therein. When the housing member is in an unlocked state, the clamping portions can move in a variety of directions. When in a locked state, the housing member cannot move with respect to the tube that it is coupled to. The position and orientation of the fixation pin is also set. The locked and unlocked state of the housing member is determined by the positioning of a locking pin coupled to the housing member.

A correction clamp assembly that permits a physician to surgically correct a bunion or similar deformity is provided. The assembly includes an elongate bridge, as well as first and second blocks slidably or rotatably connected to the elongate bridge. More specifically, first block is configured to slide along a slot formed in the elongate bridge, as well as rotate relative thereto. Additionally, the second block is configured to rotate relative to the elongate bridge. First and second pins may be configured to extend through the first and second block, and then into various pieces of bone. Once a cut is made in a portion of joint or bone, the pins can thereafter be moved towards and away from one another to position the respective pieces of bone in a desired location. Locking screws may also be provided to releasably secure the blocks relative to the bridge.

An external fixation system may have a first bone anchoring body configured to be secured to a first bone, a second bone anchoring body configured to be secured to a second bone, and a first strut assembly. The first strut assembly may have a first end configured to be removably coupled to the first bone anchoring body, a second end configured to be removably coupled to the second bone anchoring body, an intermediate portion that extends between the first end and the second end, the intermediate portion having a length that is adjustable, and a clutch mechanism. The clutch mechanism may be movable between an unlocked position in which the clutch mechanism allows both increase and reduction in the length, and a restricted position in which the clutch mechanism allows one of increase and reduction in the length while restricting the other of increase and reduction in the length.

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.

The present invention provides two types of a line-shaped paw-type patella external fixator, comprising A type: two ends of a line-shaped main girder are respectively provided with pressure regulating fixing parts, an arc auxiliary girder is arranged below the line-shaped main girder, and two ends of the arc auxiliary girder are respectively provided with one auxiliary fastener and fixing needles; B type: one end of B type is the same with that of the A type, a b-shaped fixing part is provided below a q-shaped fixing part on the other end, a fixing needle is provided below the b-shaped fixing part, an auxiliary fastener is provided in the middle of the line-shaped main girder, and a splayed needle seat and an auxiliary fixing needle are arranged on both sides. The fixator has advantages of easy installation, wide adjustment range and minimal damage.

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 which are configured to rotate relative to one another when the fixator assembly is in an unlocked position.

A clamping device for attaching to an external fixation element of an external fixation system includes a first jaw having an inner surface and an outer surface and includes a second jaw having an inner surface and an outer surface, with the inner surface of the first jaw and the inner surface of the second jaw together forming a passage configured to receive the external fixation element of the external fixation system. A locking system is engageable with the first and the second jaws. A portion of the locking system is moveable relative to the first and the second jaws between a first position where the locking arrangement is configured to prevent release of the external fixation element having a first size from between the first jaw and the second jaw and a second position where the locking arrangement is configured to prevent release of the external fixation element having a second size from between the first jaw and the second jaw.
