M2a 38mm

Biomet's M2a-38™ is the next great milestone in our metal-on-metal family. The patent pending onepiece design of the M2a-38 incorporates a 38mm articulating surface with metal-on-metal to achieve maximum range of motion, stability and minimal wear. The solid, cobalt chromium cup affords surgeons the ability to fit the M2a-38 cup into smaller acetabulums, which would be too small for a modular design.

Innovative Design
Unique design features such as titanium plasma spray, a 17° rim flare, and four pairs of small fins provide excellent initial fixation in the anterior and posterior columns. Rim screw options are available in size 56mm cups and above, providing supplemental fixation for difficult primary and revision surgeries.

Maximum Stability, Minimal Wear
Unprecedented stability and ROM, without increased wear, makes the M2a-38 the ideal hip articulation for many patients. The large 38mm bearing surface exhibits similar wear characteristics to that of the 28mm and 32mm metal-on-metal articulations, approximately 1/350th the wear of metal-on-polyethylene.(1) As with all of our metal-onmetal components, 100% of the M2a-38 bearing surface components are checked to the tightest tolerances and engineered to provide ideal fluid lubrication over the bearing surface.
