A New Standard in Bone Marrow Harvesting for Stem Cell Therapy in Orthopedics: Bio-MAC at Riordan-McKenna Institute

 

The reason that bone marrow harvesting has earned a bad reputation over the years for being very painful is because of the way many doctors do it.

Some doctors use a mallet with an Imbibe bone marrow aspiration needle, which looks similar to that nail-like contraption you see the doctor pounding into the patient’s bone in the picture.

Thankfully, doctors don’t use claw hammers these days. That practice went out years ago. Now, they use surgical mallets like the one pictured to the right.

Surgical Mallet

It’s easy to see why bone marrow collection with a mallet and Imbibe needle are done with the patient asleep and how patients can end up with painful bone bruising afterwards.

Other doctors use a modern Jamshidi to collect bone marrow, which is also a T-like device similar looking to the one pictured above. The biggest difference between the modern Jamshidi and the Imbibe is that the Jamshidi is not pounded in with a mallet. It’s actually forced through the bone by hand while twisting it back and forth.

Neither of these methods seem very pleasant, do they? Well they’re not!

The picture directly above shows that with the Bio-MAC, there are no large fractures connected to the hole.

However, with a Jamshidi one can easily see fracture lines,. Blood can enter through these fractures, flowing underneath the covering of the bone, which can cause bruising and pain.


 

The Bio-MAC advantages are three-fold:

  • 1) The Bio-MAC’s gentle insertion process makes harvesting bone marrow relatively painless. So much so, that Dr. McKenna routinely harvests it in under local anesthesia while the patient is awake.
  • 2) The Bio-MAC’s eliminates the type of damage that is caused by forcing a Jamshidi into the bone like serious bruising and pain that can sometimes last for months afterward.
  • 3) The Bio-MAC greatly reduces trauma and turbidity (cloudiness and particles in the bone marrow), thus minimizing clotting, which increases the efficiency of the draw and can result in greater stem cell counts.

The Bio-MAC cannula system is just one of the advanced innovations that sets the Riordan-McKenna Institute apart.
