Arthrodesis

Arthrodesis, also known as artificial ankylosis or syndesis, is the artificial induction of jointossificationbetween two bonesvia surgery. This is done to relieve intractable painin a joint which cannot be managed by pain medication, splints, or other normally-indicated treatments. It is most commonly performed on joints in the spine, hand, knee, and ankle.

It can be done in one of two ways:

• A bone bridge can be created between the two bones using a bone from elsewhere in the person's body or from a bone bank to stimulate bone growth.
• Metal implants can be attached to the two bones to hold them together in a position which favors bone growth.

At the completion of surgery and healing, which takes place over a period of several months to over a year, the two adjoining bones are fused and no motion takes place between them. This can have the effect of actually strengthening the bones, as in anterior cervicalfusion.
