Abstract
A spinal implant is provided that includes a body extending in direction at least substantially along a body axis, between a first end portion and a second end portion. The spinal implant also includes a first bearing surface disposed relative to the first end portion, and defining a first relief pattern that is configured to inhibit movement of the spinal implant relative to one or more vertebrae in at least substantially all directions. A method for manufacturing the spinal implant involves use of selective laser sintering.
Claims16
A medical implant, comprising:
- a body extending between a first end portion and a second end portion thereof;
- a first bearing surface disposed relative to the first end portion;
- the first bearing surface defining a plurality of protrusions which each extend along a respective protrusion axis that passes through a respective apex of the respective protrusion;
- wherein the respective protrusion axes extend in different random directions towards and/or away from a same body axis extending between the first end portion and the second end portion of the body;
- wherein the plurality of protrusions comprise a first pair protrusions, a second pair of protrusions, and a third pair of protrusions;
- wherein the each of the first pair of protrusions are adjacent to each other, each of the second pair of protrusions are adjacent to each other, and each of the third pair of protrusions are adjacent to each other;
- wherein an angle β is formed between the first pair of protrusions, an angle α is formed between the second pair of protrusions, and an angle γ is formed between the third pair of protrusions;
- wherein each of the angle β, α, γ are different.
