KÜNSTLICHE BANDSCHEIBE

An artificial disc implant consists of two end plates (1,2) which border on a hollow area (4) that is filled with an elastic and/or plastically deformable nucleus (3). The hollow area is enclosed by a tubular fibre ring (5), and the end plates and ring are connected. The ring can expand elastically...

Beschreibung
Zusammenfassung:	An artificial disc implant consists of two end plates (1,2) which border on a hollow area (4) that is filled with an elastic and/or plastically deformable nucleus (3). The hollow area is enclosed by a tubular fibre ring (5), and the end plates and ring are connected. The ring can expand elastically in both axial and radial directions, and the ring has a larger modulus of elasticity than the nucleus. The elastic characteristics of the disc, relating to compression, are non-linear.
