Definitions

  • the present invention relates to external fixator systems and, more particularly, external fixator systems having a radiolucent fixation element with radio-opaque alignment structures.
  • the external fixation system may be used in the repair of traumatized bone.
  • the system structure typically includes transcutaneous pins and/or wires attached to an external structural frame and to bone.
  • the frame may include one or more clamps, bars, connecting rods, struts, rings, 2/3 rings, half rings, foot plates, or curved rods.
  • the frame portions are attached and spaced apart but structurally connected using a plurality of connecting rods or displacement members, such as tie rods or struts.
  • a surgeon can use several rings and several displacement members in order to create an overall frame about the patient's arm or leg.
  • Transversely extending pins or wires attach to these rings and then extend transversely from the rings into the bones, so that the frame and transverse pins support and/or load the bone tissue in a desired manner.
  • a system utilizing circular or semi-circular rings with adjustable rods is generally referred to in the art as an "Ilizarov" system and can be used for the purpose of external fixation of heavily damaged or heavily traumatized bone.
  • the "Ilizarov” method can also be used for lengthening various congenital and acquired shortenings and other defects of skeletal segments wherein the rings and adjustable tie rods form part of compression-distraction apparatus.

  • the typical external frame has many elements that are radio-opaque. These elements are structural and not optimized for aligning external components with internal bone structures. For example, a surgeon might use a bolt within an Ilizarov external fixation ring to align the ring with the bone. Because the bolt is radio-opaque, the surgeon can attach the bolt to the fixator, obtain an x-ray, and then adjust the fixator using the bolt and x-ray as a guide to place the fixator relative to a bone. However, the fixator is also opaque, which it makes it difficult to see the underlying structure.

  • the visual targets are offset from the face of the ring, they may pose interference or impingement hazards during assembly of the fixation system.
  • attachment and verification of the visual targets increase the time necessary for assembly of the fixation system.
  • the visual targets may become bent and damaged and thereby provide false indications of location.
