Process of fabricating implants having three distinct surfaces

a technology of three distinct surfaces and implants, applied in the field of spinal implants having at least three distinct surfaces, can solve the problems of impaired discs, affecting the anatomical functions of vertebrae, and affecting the health of discs, so as to avoid unintentional laceration or abrasion of delicate soft tissues, improve the effect of bone remodeling and fusion response, and improve the effect of fusion

Embodiment Construction

[0035]Certain embodiments of the present invention may be especially suited for placement between adjacent human vertebral bodies. The implants of the present invention may be used in procedures such as Anterior Lumbar Interbody Fusion (ALIF), Posterior Lumbar Interbody Fusion (PLIF), Transforaminal Lumbar Interbody Fusion (TLIF), and cervical fusion. Certain embodiments do not extend beyond the outer dimensions of the vertebral bodies.

[0036]The ability to achieve spinal fusion is directly related to the available vascular contact area over which fusion is desired, the quality and quantity of the fusion mass, and the stability of the interbody spinal implant. Interbody spinal implants, as now taught, allow for improved seating over the apophyseal rim of the vertebral body. Still further, interbody spinal implants, as now taught, better utilize this vital surface area over which fusion may occur and may better bear the considerable biomechanical loads presented through the spinal col...

Abstract

Processes of fabricating different surface topographies, which may include separate macro processing, micro processing, and nano processing steps, in order to produce an interbody spinal implant having at least three distinct surfaces including (1) at least one integration surface having a roughened surface topography including macro features, micro features, and nano features, without sharp teeth that risk damage to bone structures; (2) at least one graft contact surface having a coarse surface topography including micro features and nano features; and (3) at least one soft tissue surface having a substantially smooth surface including nano features.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of U.S. patent application Ser. No. 13 / 557,727, filed on Jul. 25, 2012, which is a continuation-in-part of U.S. patent application Ser. No. 12 / 151,198, filed on May 5, 2008, and issued as U.S. Pat. No. 8,262,737, which is a continuation-in-part of U.S. patent application Ser. No. 11 / 123,359, filed on May 6, 2005, and issued as U.S. Pat. No. 7,662,186. The contents of all prior applications are incorporated by reference into this document, in their entirety and for all purposes.TECHNICAL FIELD[0002]The present invention relates generally to interbody spinal implants and methods of making such implants and, more particularly, to spinal implants having at least three distinct surfaces.BACKGROUND OF THE INVENTION[0003]In the simplest terms, the spine is a column made of vertebrae and discs. The vertebrae provide the support and structure of the spine while the spinal discs, located between the vertebrae, act a...
