Definitions
- the present invention relates generally to a three-dimensional structure for use as a bone mass replacement or fusion augmentation device.
- this structure is specifically engineered from interconnecting, non-random metallic segments so as to minimize the volume of the metal to void and thereby maximize potential volume for reconstructive bone growth.
- the metallic segments or filaments are joined to form regular repeating geometric shapes to provide maximum strength and minimize potential shear planes through the structure.
- a particularly favored geometric shape is a modified dodecahedron based on pentagons.
- the resulting structure may have a general rectangular block configuration, a cylindrical configuration which can include a larger defined void area in the center.
- the present invention provides an engineered three-dimensional structure, which has a goal of providing a structure for bone to grow through for fusion or reconstructive surgery.
- the structure is further intended to be strong enough to provide support to the skeletal and muscular structure during bone rehabilitation, i.e. during the healing process when bone reconstruction occurs.
- the present invention provides a structure which is self-supporting meaning that no further substrate or support is required to provide the necessary support characteristics during rehabilitation.
- implants such as acetabular cups having porous coatings.
- these coatings can also be distinguished since the pores tend to be random and substantially smaller (by at least a magnitude or more of size) than the pores of the present invention.
- the structure is constructed of discrete subcomponents which are repeating geometric shapes, constructed of filamentary elements so as to provide regular intersticial pores and/or voids of an appropriate shape and size to allow for bone.
- the filamentary segments are providing structural support, slow in-growth can occur into the void area.
- the structure has a central void area to accommodate the bone graft or bone substitute.
- An additional aspect of the invention is the provision of a structure, which is "space-filling" meaning that structure can be expanded to any size and will maintain its shape as a repeating structure.
- the structure is ordered and not random. It is homogeneous and provides multiple planes of symmetry.
- the implant is preferably constructed from a bio-compatible cast metal such as titanium or a titanium alloy so as to maximize strength and minimize the metal artifact which would appear on sectional CT scans.
- the structure can be modified to generate the desired implant stiffness for a variety of applications.
- the structure can also be modified to increase its strength and resistance to fatigue as is necessary.
- individual filamentary members may be modified or eliminated to provide for functional structures including for example voids for bone growth voids or means to attach fasteners.
- spinal fusions such as posterior lumbar inter-body fusion ("PLIF"), anterior lumbar and inter-body fusion (“ALIF”), inter-body fusion ring, long-bone reconstruction such as humoral or femoral reconstruction, tibial-plateau reconstruction, cranial facial applications including mixillo-facial reconstruction, and pelvic- defect reconstruction.
- PLIF posterior lumbar inter-body fusion
- ALIF anterior lumbar and inter-body fusion
- inter-body fusion ring long-bone reconstruction such as humoral or femoral reconstruction
- tibial-plateau reconstruction cranial facial applications including mixillo-facial reconstruction
- pelvic- defect reconstruction cranial facial applications for mixillo-facial reconstruction.

- Figure 2 shows an end view of first embodiment shown in Fig. 1
- Figure 3 shows a top view of the embodiment shown in Fig. 1
- Figure 4 shows a second embodiment of the invention for use in anterior lumbar inner-body fusion
- Figure 5 shows a third, annular, embodiment of the invention
- Figure 6 shows a different view of the third embodiment
- Figure 7 shows a view of a fourth embodiment
- Figure 8 shows a different view and scale of the embodiment of
- Figure 1 illustrates a three-dimensional, geometric-porous engineered structure for use as a bone mass replacement for fusion augmentation device.
- the structure shown generally at 1 0 is formed from a series of inter-connected filaments 1 2, which form one or more types of repeating geometric shapes.
- a first shape 1 5 is pentagonal, while a second repeating shape is a modified dodecahedron 1 7.
- the shapes interconnect so as to define porous areas of intersticial voids 20. These areas provide space for bone to grow into during bone reconstruction or fusion.
- the structure is intended ultimately to become redundant and/or subplanted by the bone that grows into the area.
- the structure 1 0 has a generally regular overall shape.
- the structure has a block configuration with the top 25, bottom 27, side 29 and end 31 geometric structures substantially defining planes.
- the structure is generally lacking "shear planes", i.e. planes predisposed to shear failure within the structure.
- This aspect of the invention allows for the maximization of strength in every direction, including characteristics for axial, shear, and torsional stresses 1 0 to which bones are subjected, while minimizing the metallic, scaffolding or substructure.
- Figure 4 illustrates an embodiment of the invention for use in spinal inter-body fusion.
- this disc or kidney-shaped device has inner 41 an outer 40 top rings and inner 43 and outer 42 bottom rings inter-connected by filamentary struts 44 to provide the desired strength characteristics. Further, this device has a larger void 46 defined by interior rings to allow bone graft, or bone substitute to be implanted within the structure.
- FIG. 5 A similar ring implant for reinforcing weak, bony tissue is shown at 50 in Figs. 5 and 6.
- This structure is illustrated as having filamentary pentagons constructed of individual filaments 52 defining pores 51 and dodecahedron shapes similar to those shown in the first embodiment shown in Figs. 1 -3.
- the implant in Figs. 5 and 6 is ring shaped and thus includes an interior void 54 intended for the same purpose as in Fig. 4.
- Figures 7 and 8 illustrate a block-shaped structure 60 again constructed from filaments 62 joined at regular repeating angles 63 to form modified pentagons and highly modified dodecahedrons.
- modified is meant that one or more angles of the basic shape or one or more filamentary segment length has been modified from the general understanding of this geometric shape to allow the figure to close and to connect the pieces of the three-dimensional space-filling structure.
- a pentagon is a regular five-sided shape while a dodecahedron is a spherical structure formed by joining ten pentagons. This structure also has a central void 64 defined by closed octagonal inner rings 66.
- the filaments generally have a thickness of from about 0.25 millimeters to 2 millimeters preferably 0.5 to 1 .5 millimeters and most preferably 0.5 to 1 millimeter.
- the length of these filaments in a pentagonal shape is generally from about 1 millimeter to about 10 millimeters and, preferably 1 to 6 millimeters and most preferably 1 .5 to 3 millimeters.
- the dodecahedron shape has a maximum size of 20 millimeters. While cast titanium or titanium alloy are envisioned as a preferable material, the invention could be made of other bio-compatible substances including for example, PEEK, other metals, and ceramic bone substitutes could also be envisioned.
- the geometry used for the present invention envisions regular repeating convex polyhedra in three-dimensional space including for example the tetrahedron, the cube, the regular octahedron, the pentagonal dodecahedron bounded by 1 2 regular pentagons and the icosahedron, bounded by 20 regular triangles.
- the filamentary structures are joined together to form geometric shapes, which are the building blocks to form a larger configuration, meaning the general overall profile of the structure.
- the present invention would envision other configurations or structures based on these kinds of geometric shapes as well.
