Biomet's M2a-Magnum™ Hip:
The
choice for more active patients.
The M2a-Magnum™ Hip differs from traditional hip replacement
systems in three fundamental ways:
1. Metal-On-Metal
When polyethylene components were introduced, many orthopedic
device manufacturers abandoned the idea of metal-on-metal
implants. However, with modern manufacturing technologies and a
desire for greater durability, Biomet decided to offer
metal-on-metal which many surgeons prefer for patients that are
more active.
The more active a person is, the more friction on the joint and
the higher the risk of wear. However, in laboratory testing,
all-metal components demonstrated a 99 percent reduction in wear
compared to polyethylene1. So, for younger and more active
patients, metal-on-metal may be an appealing choice.
2. Greater Motion, Stability and Flexibility
Another feature of the M2a-Magnum™ Hip is its large femoral head. A larger
head design provides greater range of motion and greater
resistance to dislocation compared to smaller heads. In fact,
the M2a-Magnum™ Hip offers the potential for over 160 degrees of
range of motion.1
3. Larger Heads, Even in Petite Bodies
The
M2a-Magnum™ Hip has a large range of
available sizes that allows for better replication of a
patient's anatomy.
Only metal-on-metal components make it possible for the largest
heads to be used for all of the implant sizes. With polyethylene
and ceramic components, larger heads can only be used with
larger acetabular sockets or, more specifically, larger
patients. But with the M2a-Magnum™ Hip, regardless of physical
stature, patients can benefit from the extra mobility and range
of motion possible with larger heads.
