External fixation assembly

An external fixation assembly for bone fusion about a submalleolar region of a patient, the assembly comprising:

• a first extension arm and a second extension arm cooperable with the first extension arm, the second extension arm being pivotally connected to the first extension arm at a fixation joint portion, wherein the first extension arm includes a first threaded body having outer threads formed thereabout and the second extension arm includes a second threaded body having outer threads formed thereabout, a first pin element having a first collar formed about the first extension arm, a second pin element having a second collar formed about the second extension arm, and further wherein said fixation joint portion includes a pin clamp having a longitudinally extending bore that defines a single pivot axis about which said first extension arm and said second extension arm cooperate;
• wherein, the first pin element has a first joint portion and being moveably disposed along the first extension arm, and the second pin element has a second joint portion and being moveably disposed along the second extension arm, wherein said first joint portion and said second joint portion each includes a pin clamp having a longitudinally extending bore that defines a pivot axis, and;
• a first brace member and a second brace member cooperable with the first brace member, the first brace member being attached to the first pin element at the first joint portion, the second brace member being attached to the second pin element at the second joint portion, and further comprising a brace fastener for attaching the first and second brace members together, defining a triangular shape along the fixation joint portion, the first joint portion, and the second joint portion;
• and
• a plurality of connecting pins for bone fusion about the submalleolar region, each of the connecting pins having first and second ends, each first end being configured to engage with bone matter and each second end being configured to attach to one of said fixation joint portion, said first and said second joint portions for support, each joint portion being configured to selectively receive one of the connecting pins within said longitudinally extending bore of said pin clamp, and having a predetermined configuration for bone fusion of the bone matter.

An external fixation assembly for bone fusion, the assembly comprising:

• a first extension arm having a fixation joint portion having a pin clamp with a longitudinally extending bore that defines a single pivot axis;
• and a second extension arm cooperable with the first extension arm, the second extension arm being pivotally connected to the first extension arm at the fixation joint portion so as to pivot about said single pivot axis;
• a first pin element moveably disposed along the extension arm defining a first joint portion and a second pin element, the second pin element having a second joint portion and being moveably disposed along the second extension arm;
• wherein the first extension arm includes a first threaded body having outer threads formed thereabout and the second extension arm includes a second threaded body having outer threads formed thereabout, the first pin element having a first collar formed about the first extension arm, the second pin element having a second collar formed about the second extension arm;
• a first brace member and a second brace member cooperable with the first brace member, the first brace member being attached to the first pin element at the first joint portion, the second brace member being attached to the second pin element at the second joint portion;
• and further comprising a first set of threaded compression nuts matingly disposed about the first threaded body to selectively lock the first pin element along the first extension arm;
• and a second set of threaded compression nuts matingly disposed about the second threaded body to selectively lock the second pin element along the second extension arm;
• and
• a plurality of connecting pins for bone fusion, each of the connecting pins being configured to engage with bone matter for bone fusion and to singly attach to one of the joint portions for support.

A method of external fixation for bone fusion, the method comprising:

• disposing a plurality of connecting pins through bone matter of a patient for bone fusion about the submalleolar region of the patient;
• and
• supporting the plurality of connecting pins with a first extension arm and a second extension arm each having a fixation joint portion that defines a single pivot axis about which said first extension arm and said second extension arm cooperate and a pin element moveably disposed along each extension arm to define a first joint portion and a second joint portion, wherein the first extension arm includes a first threaded body having outer threads formed thereabout and the second extension arm includes a second threaded body having outer threads formed thereabout, the first pin element having a first collar formed about the first extension arm, the second pin element having a second collar formed about the second extension arm;
• attaching a first end of a first brace member to a first end of said first extension arm;
• attaching a first end of a second brace member to a first end of said second extension;
• and
• attaching a second end of said first brace to a second end of said second brace so as to thereby define a triangular shape along the fixation joint portion, the first joint portion, and the second joint portion.

An external fixation assembly for bone fusion, the assembly comprising:

• a first threaded extension arm and a second threaded extension arm pivotally connected to the first threaded extension arm at a fixation joint portion having a pin clamp with a longitudinally extending bore that defines a single pivot axis about which said first extension arm and said second extension arm pivot;
• a first collar and a second collar cooperable with the first collar, the first collar being moveably disposed on the first threaded extension arm and having a first joint portion, the second collar being moveably disposed on the second threaded extension arm and having a second joint portion wherein said first collar is moveably disposed along said first threaded extension arm and said second collar is moveably disposed along said second threaded extension arm;
• and further including a first brace member and a second brace member cooperable with said first brace member, said first brace member being attached to the first collar at the first joint portion, the second brace member being attached to the second collar at the second joint portion;
• and
• a plurality of connecting pins for bone fusion, each of the connecting pins having first and second ends, each first end being configured to engage through bone matter for bone fusion, each second end being configured to attach to one of the joint portions for support, each joint portion being configured to receive one of the connecting pins at a predetermined configuration for bone fusion of the bone matter, and further comprising a plurality of receiving members for securing the second ends of the connecting pins, each of the joint portions having one receiving member disposed therein to receive one second end to support the assembly for bone fusion, and a brace fastener for attaching the first and second brace members together, defining a triangular shape along the fixation joint portion, the first joint portion, and the second joint portion.
