Bone Marrow


Frequently Asked Questions

What is bone marrow aspirate concentrate?

What conditions can be helped with stem cells?

  • Stem cells can be used to help with bone healing, cartilage repair, and new blood vessel growth. They may also be used to treat delayed union or nonunion of bone fractures, cartilage defects, osteonecrosis, chronic tendon problems, or chronic wounds.

Who should not undergo this procedure?

  • Bone marrow aspirate concentrate is made from fluid taken from bone marrow. The bone marrow aspirate contains stem cells that can help the healing of some bone and joint conditions. Bone marrow aspirate concentrate is obtained with a minimally invasive procedure that avoids the risks of an open bone graft procedure.
  • This therapy is avoided in patient who have cancer or active infection.

What are the general details of the procedure?

  • In short, a needle is used to remove bone marrow from within the bone, and a concentrated fraction of the marrow is then injected into the specific site. This is typically done in the clinic using aseptic technique or in the operating room under sedation or general anesthesia. Marrow is commonly taken from the posterior pelvis using a small "poke-hole" incision, but it may also be taken from other sites of the body such as the humerus or tibia. The sample of bone marrow is removed and then spun down in a special centrifuge to separate the cells. The concentrated portion of marrow that is produced has a higher concentration of mesenchymal stem cells (MSCs). The surgeon then injects the bone marrow concentrate directly into the specific site.

What happens after the procedure?

  • After aspiration, there usually is pain at the pelvis that goes away within 3-7 days. A small dressing or bandage is kept at the aspiration site until it has healed.

What are the potential complications?

  • Complications may include pain, bleeding, infection and nerve injury. Intra-abdominal injury may occur because of the needle.

Is this procedure covered by insurance?

  • At this time, the procedure is not covered by insurance.
