Stem cells surgery on a hip

Doctors and scientists in Southampton have completed their first hip surgery with a 3D printed implant and bone stem cell graft.

The 3D printed hip, made from titanium, was designed using the patient’s CT scan and CAD CAM (computer aided design and computer aided manufacturing) technology, meaning it was designed to the patient’s exact specifications and measurements.

The implant will provide a new socket for the ball of the femur bone to enter. Behind the implant and between the pelvis, doctors have inserted a graft containing bone stem cells.

The graft acts as a filler for the loss of bone. The patient’s

Surgeons make new technique to repair bones

SURGEONS from Southampton have developed a pioneering bone repair technique that could end the need for artificial hip replacements.
Six people have undergone the procedure which uses a their own stem cells to repair damaged hip joints. Only one operation has failed (…)

Under the procedure surgeons extract bone marrow from the back of a patients’ pelvis, then extract a layer of stem cells by spinning the marrow in a centrifuge.
The stem cells are then mixed with ground up bone donated from another patients discarded hip replacement (…)

New coating for hip implants could prevent premature failure

Nanoscale films developed at MIT promote bone growth, creating a stronger seal between implants and patients’ own bone.

Every year, more than a million Americans receive an artificial hip or knee prosthesis. Such implants are designed to last many years, but in about 17 percent of patients who receive a total joint replacement, the implant eventually loosens and has to be replaced early, which can cause dangerous complications for elderly patients.

To help minimize these burdensome operations, a team of MIT chemical engineers has developed a new coating for implants that could
