Put simply, regardless of the relative share, differences in market growth rates or other metrics, some spine surgery technologies will generate substantially more sales than others during the 2012 to 2020 timeframe.
Looking at the MedMarket Diligence, “Worldwide Spine Surgery Data Forecast, 2010-2020”, posterior pedicle screw fusion systems and artificial cervical discs will generate the largest revenue increases over this period, since even at modest growth rates the size of the penetrated market results in big gains from 2012 to 2020. In other words, while AxiaLIF represents one of the fastest growing spine surgery device markets, the aggregate change in AxiaLIF revenues from 2010 to 2020 is only $270 million versus $2.97 billion for posterior pedicle screw fusion systems, Here a growth rate of under 10% on such a large existing market greatly eclipses the absolute impact of a dramatic growth rate (i.e., >30%) of an emerging market.
