M2a-Magnum

The M2a-Magnum large-diameter articulation system is an ultra-high performance metal-on-metal articulation offering superior joint mechanic restoration and full compatibility with Biomet's clinically proven hip stems.

The M2a-Magnum optimises three important principles of total hip arthroplasty:

• High Stability - large head diameter has been shown to lower the potential risk of dislocation by increasing dislocation distance (‘hop height’) to 2.2cm
   
• Good Range Of Motion – large head diameters offer an increased 162 degrees range of motion compared with other modular head systems.
   
• Low wear – Metal-on-metal articulations offer a significant wear reduction compared with metal or ceramic-on-polyethylene. 

Additional features:

• Titanium Porous Plasma Spray Coating and 4 pairs of fins enhance rotational stability and internal fixation of the acetabular component with an additional press-fit produced by a 2mm under-ream.
   
• 6 different length taper adaptors, combined with our standard and lateralised stem offsets allow for better soft tissue tensioning and appropriate anatomy restoration without leg lengthening.
   
• 2mm incremental sizing offers intra-operative flexibility for precise replication of the anatomical fit.
  - Shell Sizes: 44mm-66mm
  - Head sizes: 38mm-60mm
   
• System flexibility provided by taper adaptor compatibility with both type 1 and 12/14 stem tapers.
