Spine Surgery: Interbody Fusion Device Trends

The global market for interbody fusion devices includes those for fusion of anterior lumbar (ALIF), transforaminal lumbar (TLIF), posterior lumbar (PLIF), and axial lumbar (AxiaLIF). These are all procedures as well as devices, as, in each case, a different approach to performing the fusion surgery led to design of a device tailored to that approach. There are other Interbody Fusion Devices on the market, but the rest tend to be adaptations of these devices, i.e. a company has produced a new product (and name) and declared it to be a new way to perform the surgery. The market consists primarily of these four approaches and devices. AxiaLIF, from TranS1, is new and is the only product segment which is exclusive to one manufacturer.

Like most spine surgery device segments, the market is characterized by increasing unit volume and sales revenue, even in the face of declining prices.  Demand is simply increasing at a greater rate than prices are declining.

The balance of interbody fusion procedure volume — across anterior, transforaminal, posterior and axial — is not expected to change appreciably from 2011 to 2020, with the only significant shift being the emergence of appreciable volume in axial lumbar interbody fusion and a modest decline in the relative volume of posterior procedures.  See the unit volume shares in 2011 and 2020, below.

These trends illustrated above are at the global aggregate level.  The relative impact of forces on fusion device markets differs from country to country (see Report #M520).
