Medtronic Infuse Bone Graft Becomes Controversial Due to Safety Concerns about its Side Effects
Medtronic Infuse is a medical device that is supposed to help re-grow bone in the spine, but it has become controversial because of safety concerns. Infuse has been linked to side effects such as cancer, male sterility and, excess bone. Most recently, in November 2013, a report posted on the National Center for Biotechnology Information(NCBI) website indicated that Medtronic’s Infuse bone graft product likely caused a life-threatening problem during revision surgery. Specifically, the report said that Infuse partially contributed to fibrosis and scarring that caused the iliac vein to adhere to the area of the patient’s spine that had been previously operated on, resulting in a life-threatening vascular injury during revision surgery.
“Spine surgeons should be aware of this potential inflammatory fibrosis in addition to other reported complications related to rhBMP-2,” the authors noted.
Such complications seem to appear even more when the product is used off-label for unapproved procedures. To make matters worse, it appears that Medtronic has bribed doctors to hide the side effects associated with Infuse. Our firm has been handling defective drug and medical device issues for years, and is actively investigating Infuse cases. If you’ve had a procedure with Infuse, we’d like to hear from you.

Side Effects Linked to Off-Label Use
Infuse contains recombinant human Bone Morphogenetic Protein-2 (rhBMP-2), a protein that stimulates bone growth. It is mostly meant for a type of spine surgery called lumbar fusion. The U.S. Food and Drug Administration (FDA) has only approved Infuse for anterior approach lumbar fusion, which is performed through the front of the body. Infuse is not approved for posterior lumbar fusion, which is performed through the back. Infuse has also been cleared for two types of dental surgery.
A drug or medical device is used “off-label” when it is used in ways not covered by its formal FDA approval. It is not illegal for doctors to use medicinal products off-label as they see fit, but it is illegal for companies to promote such uses. Infuse complications are the most prevalent in off-label procedures, such as when it is used in the cervical spine (neck). In fact, the FDA has warned that using Infuse in the cervical spine could lead to life-threatening complications, including swelling of the neck and throat.
Additional side effects and complications associated with Infuse include:
- Difficulty swallowing
- Difficulty breathing
- Difficulty speaking
- Ectopic or uncontrolled bone growth near the site of the surgery
- Nerve injuries that lead to severe, chronic pain
- Ongoing or chronic pain that radiates in the arms or legs
- Male sterility (retrograde ejaculation)
- Cauda equina syndrome (CES)
Did Medtronic Hide Infuse Complications?
Medtronic Infuse Bone Graft became even more controversial in June 2011 when a group of spine experts publicly denounced research funded by the company in a study published in the Spine Journal. The authors of that study alleged that Medtronic studies on Infuse failed to report side effects, such as cancer, sterility in men, infections, bone dissolution and worsened back and leg pain. Contrary to what the Medtronic studies suggest, the Spine Journal researchers found that these complications occurred in 10 to 50 percent of patients who received Infuse in 13 Medtronic-funded trials conducted between 2000 and 2010. The review also questioned the financial relationship between the company and the researchers who did the studies; the median amount paid to the doctors was between $12 million and $16 million per study, although none of the royalty payments were related to Infuse.
A government investigation found evidence that the Medtronic-funded studies were biased. According to a United States Senate Finance Committee report, Medtronic employees helped write and edit 11 out of the 13 studies. This “ghostwriting” is not illegal, but it is considered a serious breach of integrity in the scientific community.
