Bionic Ankle

Military veteran Jesse Murphree was injured northern Afghanistan. His injuries were so severe that his legs were amputated above the knees. He's been walking on prosthetic legs for about since then.

He has done quite well but really gets tired because of the energy it takes to walk on prosthetic legs. But, with the advances in prosthetic technology, Jesse will get some relief from some of the energy demand. He was fit with new bionic ankles which give him more "spring in his step".

Bone Tumor Surgery makes Colorado Teen the "Bionic Boy"

Ron Hugate, MD, Orthopedic Oncologist with the Denver Clinic for Extremities at Risk employed new technological advances in orthopedic surgery implants to rebuild a Colorado teen's leg after the teen underwent treatment for a bone tumor.


Jason Lansdown underwent the Extremities at Risk interarterial chemotherapy protocol to kill the osteosarcoma in his lower leg. After the bone tumor surgery and the tumore was removed, Dr. Hugate used foam metal technology to reconstruct Jason's leg. This technology allows bone to grow into the metal prosthesis, resulting in a reconstruction that is more natural bone than metal. Ultimately stronger, and potentially able to heal itself if necessary.
