A broken talus of a road accident victim was replaced by 3D Printed Implant. The patient had come to Loyola for an alternate option as all the other hospital suggested procedures that limited her movement.

In 2017, Deborah Stoneburner was in a severe car accident, and among her injuries was a crushed ankle bone called the talus.

Loyola Medicine orthopedic surgeon Adam Schiff, MD, successfully replaced the damaged bone with a metal talus made with 3D printing technology.

The talus lies above the heel bone and below the tibia and fibula bones of the lower leg. It's responsible for ankle movements up and down and side to side.

Conventional treatment for such injuries is to fuse the ankle bones into one bone. While a fusion relieves pain, it also eliminates joint motion. A second treatment is to amputate and replace with a prosthesis.

Ms. Stoneburner came to Loyola for a third option: a 3D printed implant. In 3D printing, an object is made from a three-dimensional digital model. In Ms. Stoneburner's case, CT scans were taken of the talus in her uninjured foot and sent to Additive OrthopaedicsŪ, which made a replica of her talus. Dr. Schiff performed a surgery to remove the damaged talus and replace it with the metal bone.

Talus replacement with a 3D printed implant is a rare surgery that typically is only performed at an academic medical center such as Loyola, Dr. Schiff said.

After wearing a cast and recovering from the surgery, Ms. Stoneburner has returned to work and is walking again. "Dr. Schiff did a great job getting me back to where I wanted to go," she said.

The technology of 3D printing is being used in many areas of medicine, particularly orthopaedic surgery, Dr. Schiff said. "At Loyola, we are working with our industry partners to advance this science for our patients."
