  • Patent number: 6702814
    Abstract: A clamp assembly for an external fixation system includes a first clamp member for engaging a first elongated member. The first clamp member includes a first jaw portion and a second jaw portion. The first and second jaw portions at least partially defining a laterally extending channel for receiving the first elongated member. The first and second jaw portions or members are connected by a hinge portion. The first jaw member includes a free end normally spaced apart from a free end of the second jaw a distance less than a diameter of the first elongated member. The first clamp member is elastically deformable to receive the first elongated member between the free ends of the first and second jaw members and into the laterally extending channel.

  • Patent number: 6616664
    Abstract: A clamp assembly for an external fixation system includes a first clamp member receiving a first elongated and a second clamp member receiving a second elongated member. The first clamp member includes a first fastener rotatably in a first direction to lock the first elongated member relative to the first clamp member. A second fastener connects the first and second clamp members. The second fastener is rotatable in the first direction to independently lock the second elongated member relative to the second clamp member. The first fastener is hollow and the second fastener passes through the first fastener.

  • Patent number: 6277119
    Abstract: An external fixation system for securing a first bone portion in a fixed relationship with respect to a second bone portion. The fixation system includes at least one cylindrical support rod and a plurality of universal clamp assemblies for engagement with at least one support rod. The fixation system additionally includes various other distinct components for interconnecting the support rod with bone pins engaged with the bone. Some of the other components are formed to include serrations for engaging corresponding serrations provided on the universal clamp assemblies. Some of the components include a cylindrical portion, whereas other of the components include a rod receiving portion adapted to receive the at least one support rod or one of the cylindrical portions. These interchangeable and distinct components allow for a greater degree of surgeon flexibility in producing a desired construction to secure bone portions with bone pins.

  • Patent number: 6152925
    Abstract: An apparatus for adjustably securing the humerous, which is on a proximal side of elbow joint, relative to the ulna on the distal side of the elbow joint. The apparatus includes a central body having inner and outer ring members interconnected for relative rotation about a common mechanical axis adapted to align with the anatomical axis of the elbow joint. The central body defines a radiographic window for permitting lateral radiographic examination of the anatomical pivot axis of the elbow joint. The apparatus preferably includes a distraction mechanism for distracting the humerus perpendicular to the proximal end of the ulna.

  • Patent number: 6010501
    Abstract: An external fixator for securing a first bone portion in a fixed relationship with respect to a second bone portion. The fixator includes a bone screw clamping assembly for receiving a first bone screw which is connected to the first bone portion and which includes a spherical portion. The fixator further includes a bone screw clamping assembly which is operable to receive a second bone screw which is connected to the second bone portion and which has a spherical portion. The fixator also includes a connection member having a main body portion and an internal module adjustably mounted within the main body portion. The internal module receives a spherical end of one of the bone screw clamps and selectively permits universal movement thereof. The internal module may be linearly adjusted within the connection member independently in first and second directions which are substantially perpendicular to one another.
