Abstract
Provided are methods and systems for fabricating multimaterial bodies in a layer-wise fashion, which bodies may be used bone-stabilizing implants. The multimaterial bodies include rigid and flexible portions that are integrally formed with one another. The multimaterial bodies may be softened or stiffened in specific areas to match the biological or anatomical features of a bone.
Claims29
An implant for stabilizing a fracture in an underlying bone, the implant comprising:
- a first region comprising a first material configured to be attached to the underlying bone;
- and
- a second region comprising a second material that is different than the first material, the second region being disposed adjacent the first region,
- the second region having a flexibility different than that of the first region,
- the first and second regions being monolithic with one another,
- the first region comprising at least one aperture configured to receive an anchor configured to secure the implant to the underlying bone, and
- the implant being configured for installation across a fracture in the underlying bone so as to provide stability to the underlying bone.

An implant for stabilizing a fracture in an underlying bone, the implant comprising:
- a first region comprising a metal and the first region configured to be attached to the underlying bone;
- and
- a second region disposed adjacent the first region,
- the second region comprising a polymer and having a flexibility different than that of the first region,
- the first and second regions being monolithic with one another,
- the implant comprising a transition region between the two regions, the transition region comprising a mixture of the metal of the first region and the polymer of the second region,
- the first region comprising at least one aperture configured to receive an anchor configured to secure the implant to the underlying bone, and
- the implant being configured for installation across a fracture in the underlying bone so as to provide stability to the underlying bone.
