K2M announces the U.S. commercial launch of MESA 2 Deformity Spinal System

The Next-Generation MESA System is Poised to Address the Most Difficult Correction Maneuvers for Complex Spinal Pathologies

K2M Group Holdings, Inc. (Nasdaq:KTWO) (the "Company" or "K2M"), a global medical device company focused on designing, developing and commercializing innovative and proprietary complex spine technologies, techniques and minimally invasive procedures, today announced the U.S. commercial launch of the MESA^® 2 Deformity Spinal System, the Company's next-generation pedicle screw system designed to address the most complex spinal pathologies. MESA 2 carries forward the hallmarks of the Company's complex spine MESA technology, while offering new capabilities to enhance user experience.

"Following a successful Alpha phase, we are excited to announce the commercial launch of our MESA 2 Deformity Spinal System and the upcoming rollout across the United States," stated Eric Major, K2M's President and CEO. "MESA 2 is the much-anticipated upgrade to our flagship MESA platform and is designed to save time by cutting the number of basic surgical steps in half. We take great pride in being viewed by the surgeon community as a company that is focused on innovation and differentiation, and we remain committed to developing products that will help improve the lives of patients suffering from the most complicated spinal pathologies."

"MESA 2 includes enhancements to the original MESA technology and instrumentation," said Laurel C. Blakemore, MD, chief and associate professor of pediatric orthopaedics in the department of orthopaedics at the University of Florida. "This new system is yet another example of K2M's pioneering efforts to design innovative solutions for correcting spinal deformities."

The MESA 2 Deformity Spinal System features the next-generation MESA 2 screw, a top-loading, low-profile screw that offers a dual-lead thread pattern for fast insertion. K2M's MESA Technology also features Zero-Torque Technology^®, which offers surgeons the ability to one-step lock without torsional stress being applied to the spine. Both deformity polyaxial and uniplanar screws are available in this new system.

Designed to increase efficiency, MESA 2 also features a variety of easy-to-use reduction and spinal manipulation instruments. The Quicket^™ is an updated, quicker version of K2M's breakthrough Cricket^® rod reduction technology that provides quick on/off capabilities, while correcting the spine in all three planes. Additionally, the Over Quicket Final Locker allows for one-step locking over the Quicket, thus eliminating the need to partial lock.

In January, the Company announced it had obtained 510(k) clearance from the U.S. Food and Drug Administration to market MESA 2. To date, nearly 70 surgical cases using MESA 2 have been completed.
