Cobalt Chrome Definition

Cobalt-Chrome is the mixture of metals forming cobalt-chromium-molybdenum alloy used in many surgical implants.

The metal has been a preferred material for implant surgeries, particularly total hip replacement, because it is tolerated well by the body. In the spine, cobalt chrome is used with some artificial disc replacement devices but otherwise has had limited usefulness.

It is not very MRI compatible, and imaging the spinal canal postoperatively can be problematic.
