According to a new series of reports on the U.S. minimally invasive spinal (MIS) implants market by iData Research (www.idataresearch.com), growth has increased across all market segments as regulations become better adapted to MIS procedures. One of the key drivers for the MIS spinal device market is the increase in the target population, which is composed of aging baby boomers. The majority of procedures are performed on those individuals in the final third and quarter of their lifespan, usually over the age of 60. This age group is the fastest growing demographic in the United States. Despite rising procedural demand, market growth is expected to remain relatively stable as market saturation in certain MIS segments begins to offset overall growth.
“Growth in the minimally invasive spinal implant market is largely driven by the advantages of minimally invasive surgery over open surgery; these include reduced trauma, shorter hospital stays, lower post-operative medication use and earlier return to work,” explains Jeffrey Wong, Strategic Analyst Manager at iData Research. “However, growth is expected to slow as a result of the increasing penetration of MIS procedures into the traditional fusion market and a growing motion preservation market.”
The MIS interbody market continues to see a shift toward oblique lumbar interbody fusion (OLIF) and lateral lumbar interbody fusion (LLIF) devices and away from minimally invasive posterior lumbar interbody fusion (MIPLIF) and minimally invasive transforaminal lumbar interbody fusion (MITLIF) devices. The oblique and lateral lumbar approaches are expected to see more growth than their posterior and transforaminal lumbar counterparts, although positive growth is expected across all segments.
The fastest growing implant segment is the MIS sacroiliac joint fusion market, first introduced with SI-BONE’s iFuse Implant System® at the end of 2009. This market has experienced rapid growth as a result of reimbursement policy changes and new product entrants. Growth will also be driven by increasing an awareness of SI joint dysfunction and improvements in diagnostic processes. However, following the rapid expansion in recent years, market growth is expected to stabilize over the coming years.
NuVasive is the leading competitor in the U.S. minimally invasive spine market. The company has experienced strong growth and has the leading share in the MIS interbody device segment, as well as shares in the MIS pedicle screw, spinous process fixation, and facet fixation segments. Medtronic has the second largest overall share in the U.S. minimally invasive spine market. Medtronic will be driven by its minimal access spine technology (MAST) systems, which include the METRx™ system, the CD Horizon® Sextant™ percutaneous cannulated screw system, the CD Horizon® Legacy™ percutaneous PEEK rod system and the CD Horizon® Longitude®. Medtronic’s MIS spinal fusion technologies are further complemented by their other MIS procedures such as the X-Stop® interspinous spacer and the KYPHON® balloon kyphoplasty system. Additional competitors in the U.S. MIS market include DePuy Synthes, Globus Medical, Stryker, K2M and Richard Wolf among others.
