6 Trends in Minimally Invasive Spine Surgery

Staff -   Print  |
Minimally invasive spine procedures involving the use of facet fixation products are expected to grow faster than other sectors of the spine surgery market over the next five years, according to US Markets for Minimally Invasive Spine Technologies 2008. The high growth rate is due to increasing adoption of facet screws, bolts and allograft implants, says the report from Millennium Research Group, a leading provider of strategic information to the healthcare sector.

Here are 6 key statistics and trends in MIS covered by the report.


1. The U.S. MIS market, comprising minimally invasive spinal fusion implants, facet fixation devices, intradiscal therapies and discography devices, will expand at a compound annual growth rate of nearly 30 percent through 2006 to 2012.

2. Minimally invasive spinal fusion implants are the most-often-used technology in this area, followed by intradiscal therapies, facet fixation devices and discography devices.

3. The minimally invasive spinal fusion market was dominated by spinal implants in 2007, followed by interbody devices and access instrumentation. Growth in these procedures will be driven by "individuals with chronic back pain [seeking] a solution to their pain that allows them to recover as quickly as possible" and "MI techniques used in complex procedures, spanning more levels" are aided by "innovative products with the ability to span several levels," reports MRG.

4. The use of facet fixation devices is expected to increase by a compound annual growth rate of 60 percent from 2007 to 2012; the increased adoption is due to "innovative products … which feature greater ease-of-implantation and increased efficacy," says MRG. Further, use will increase as, "collectively, these new facet fixation technologies are successfully cannibalizing cases that would have been previously treated with pedicle screws, such as grade 1 and 2 spondyloisthesis."

5. Intradiscal therapies — comprising plasma disc decompression, intradiscal electrothermal annuloplasty and percutaneous disc compression products — "have had trouble obtaining national reimbursement coverage due to payor concern over the long-term efficacy of the technologies," says MRG. However, adoption is expected to grow steadily and the reimbursement atmosphere expected to become more favorable as "market leaders … continue promoting the benefits" heavily.

6. Over the next five years, the U.S. discography market expansion will be driven by "increasing numbers of spinal pathologies, such as DDD, that require accurate diagnosis due to the growing aging population suffering from age-related diseases and conditions," says the report.

A statistically significant survey of 72 U.S.-based spine surgeons was used to inform the analysis. Visit MRG's Web site to learn more about the company or to order a copy of the report.
