Title:
BONE IMPLANT AND INSERTION TOOLS
Document Type and Number:
WIPO Patent Application WO2003037228
Kind Code:
A3
Abstract:
Spinal and other implants may be bone or synthetic material shaped as rings, C-shaped or rectangular and so on. The implants have one or more recesses aligned in an insertion direction at either or both outer peripheral sides of the implant. In a ring implant, e.g., formed from a transverse slice of the diaphysis of a long bone or otherwise, the recesses are aligned overlying the opposing sides of the ring parallel to the insertion direction, which sides are stronger than the more central region overlying and aligned with a central chamber in the implant. One or two spaced recesses on opposite sides (150) of an implant have surface(s) transverse to the insertion direction receive the tips of implant insertion gripping jaws for receiving an insertion load imparted by the tips.
