Spinal fusion bone grafting

Spinal fusion surgeries are performed to treat a variety of diseases such as hernia and lower back pains, and are performed 1 million times worldwide each year. A severe limitation of this operation is that bone has to be isolated from another body part from the patient and transplanted to grow the spine segments together.

No alternative to current problems

The current bone transplant substitutes are either ineffective in inducing new bone formation, or dangerous because they rely on a high amount of growth factor proteins.

Summary of problem

  • 60%
    of patients experience

  • 20%
    of patients have complications at donor bone site
  • 45min
    of increased operation time
  • 25%
    of operations fail mainly due to insufficient harvestable bone
