Japanese Patent JP4210667
Kind Code:
B2
Abstract:
The implant is assembled of two outer shells (115, 117) to be inserted between the prepared vertebrae and the inner core (119) accommodated between them. The core (119) is of a lens shape and has two articulation areas (149) differing from the complementary areas (147) located at the inner surfaces of the outer shells. The areas positioned at the core surface (149) can be designed with a more intense curvature optimizing the shock absorbing quality of the core (119) which can be assembled of two parts and/or fitted with a supporting cushion.
