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 own bone marrow cells have been added to the graft to provide a source of bone stem cells to encourage bone regeneration behind and around the implant (…)
“The bone graft material that has been used has excellent biocompatibility and strength and will fill the defect behind the bone well, fusing it all together.”
Over the past decade Mr Dunlop and Professor Richard Oreffo, at the University of Southampton, have developed a translational research programme to drive bone formation using patient skeletal stem cells in orthopaedics.
The graft used in this operation is made up of a bone scaffold that allows blood to flow through it. Stem cells from the bone marrow will attach to the material and grow new bone. This will support the 3D printed hip implant.
Professor Oreffo comments: “The 3D printing of the implant in titanium, from CT scans of the patient and stem cell graft is cutting edge and offers the possibility of improved outcomes for patients (…)
