One thing to keep in mind about the spine surgery market is that, without exception, each and every technology continues to grow from the underlying procedure volume and even if prices are declining (as they are in some cases) the resulting market is also increasing as a result of procedure volume increases.
Hence, for the sake of highlighting where the growth stands out, it is useful to see the change in each technology's share of the total market over the 2010 to 2020 period.
Below is illustrated the change in percent of total market between 2010 and 2020 for each of the key technologies in spine surgery. First among these in gaining relative share are lumbar artificial discs and posterior pedicle screw fusion systems.
