71 words
An implant for the vertebral column directly arrangeable between two adjacent vertebral bodies (50), characterised in that the implant (10) comprises at least two rigid discs (11 to 14, 21, 35, 45, 53), fixable radially to each other and stackable on each other, of identical or different heights and, depending on the vertebral position, the bearing surfaces (20) for the vertebral bodies are parallel or at an angle to each other.
Claim 2
Dependent Claim
28 words
An implant according to Claim 1, characterised in that the discs are in the form of annular discs (35, 45, 53) with a respectively regular or irregular periphery.
Claim 3
Dependent Claim
