How BalancedBack® Is Different


Who are the people behind this site?

Dr. Scott Hodges, Dr. Craig Humphreys, and Dr. Marc Peterman are the original inventors of the BalancedBack® technique and associated instrumentation. The three met at Medtronic in the early 2000s, where they developed the core IP portfolio and concept. Later, they took the technology private with Medtronic’s support, forming International Surgical SEZC, a Cayman company dedicated to bringing Total Lumbar Arthroplasty to the world market. All three are recognized innovators in the spine care space, with particular contribution in the area of posterior lumbar instrumentation. Drs. Humphreys and Hodges were early innovators of the TLIF procedure, developing J&J’s DEVEX cage and other early concepts. Dr. Peterman developed many successful products including Medtronic’s CAPSTONE, the most widely-used fusion cage in the world.

Despite their experience with fusion instrumentation for lumbar pathologies, the team remained dissatisfied with the clinical outcomes of fusion surgery. They believe motion-sparing (arthroplasty) stabilization of the lower back is the solution, and have made it their personal mission to make this technology available to millions of people everywhere, in every market.


What is the purpose of the site?

As a company, our goals are twofold: to increase awareness of spinal fusion outcomes and to provide education around an alternate treatment path. The clinical literature is increasingly clear that fusion should be a last resort for treating back and leg pain, rather than a the commonly-recommended procedure we see today. Regardless of the treatment alternative chosen by patients, we believe there is great value in providing education about spinal fusion, surgical and non-surgical alternatives to fusion, and our own method of surgical intervention.
