摘要:
Intervertebral disc implants are provided for augmenting the annulus of the disc in a manner to bear at least part of the axial and/or torsional load on the annulus so that rents, fissures and subsequent herniation of the disc are prevented or substantially delayed. An aspect of the subject devices is that they have an operative height dimension that is equal to or less than the disc height of a normally functioning, healthy disc. Methods and tools are also provided for the minimally invasive implantation of the device within an intervertebral disc.
