As analyzed in this report, emerging markets such as annulus repair and nucleus repair/replacement could begin to limit the growth of artificial discs towards the end of the forecast period. Annulus repair, which can be used as a simple adjunct to discectomy, will see rapid adoption through 2013, particularly among newer surgeons. The market for nucleus replacement products, which should see some steady growth after 2010, is expected to grow substantially after the introduction of biological repair products, which could occur as early as 2012. By reducing the need for total disc replacement, these technologies will contribute to slower growth in the market for artificial discs after 2013.
