Abstract
A surgical implant having a surface treatment which contains primary cavities and secondary cavities. The primary cavities are larger than the secondary cavities and the primary cavities have an average length ranging from 20-500 micrometers. The surface treatment includes recasted material adjacent to a plurality of the primary cavities.
Claims17
A method for stabilizing a spine comprising the steps of:
- providing a surgical implant comprising:
- an implant body sized to be implanted in a patient and adapted to be in contact with a bone of the patient, the implant body having a surface treated outer surface, the outer surface containing a plurality of primary cavities and a plurality of secondary cavities smaller than the primary cavities,
- wherein the outer surface comprises recasted material adjacent to the primary cavities;
- wherein the recasted material has an average height of 1-100 micrometers, the primary cavities have an average depth of 19-499 micrometers from a surface of the implant, and the secondary cavities have an average depth of 5 nanometers to 10 micrometers.
- positioning the surgical implant on a portion of the spine.

A method for stabilizing a spine comprising the steps of:
- providing a surgical implant comprising:
- an implantable body formed at least in part of a metal sized and configured to be inserted in a disc space, the body having an upper surface and a lower surface, wherein at least one of the upper surface and the lower surface includes a surface treatment which contains primary cavities and secondary cavities, the primary cavities being larger than the secondary cavities and the primary cavities having an average length ranging from 20-500 micrometers,
- wherein the surface treatment includes recasted material adjacent to a plurality of the primary cavities,
- wherein the recasted material has an average height of 1-100 micrometers, the primary cavities have an average depth of 19-499 micrometers from a surface of the implant, and the secondary cavities have an average depth of 5 nanometers to 10 micrometers;
- positioning the surgical implant between adjacent vertebral bodies.
