[extropy-chat] artificial spinal disc

[Ned Late]

 In October 2004 the FDA approved a cobalt-chrome
disc, manufactured by Depuy Spine, Inc., of
Raynham, Massachusetts, for patients with degenerative
disc
disease. The three-piece device has a sliding
medical-grade plastic core sandwiched between two
metal plates, which allows the spine to move.
Patients must have pursued nonsurgical treatment
for at least six months to be eligible for this
surgery.
Dr. Jeffrey Goldstein, a spine surgeon at New York
University Hospital for Joint Diseases, has inserted
a few dozen of a similar device, the ProDisc
implant, manufactured by Spine Solutions of New
York, into patients as part of a clinical trial.
Goldstein thinks artificial discs will give patients
more mobility than fusion surgery.
