New pen-like device to repair broken bone

Doctors may soon be able to ‘draw’ new bone, skin and muscle on to patients, after scientists created a pen-like device that can apply human cells directly on to seriously injured people.

The device contains stem cells and growth factors and will give surgeons greater control over where the materials are deposited.

It will also reduce the time the patient is in surgery by delivering live cells and growth factors directly to the site of injury, accelerating the regeneration of functional bone and cartilage, scientists said.

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

Stem Cell Research- Drug Speeds Healing of Bone Fractures

Stem Cell Research Yields Benefits for Broken Bones
Stem Cell researchers have discovered that a drug for osteoporosis actually has a positive side effect- it can speed up the healing of bone fractures or broken bones by stimulating the patient’s own Adult Stem Cells.

Stem cell can fix broken bones

Researchers have pioneered a new technique combining bone stem cells with a degradable rigid material to encourage real bone to regrow.

The material developed by the Universities of Edinburgh and Southampton is a honeycomb scaffold structure that allows blood to flow through it, enabling stem cells from the patient’s bone marrow to attach to the material and grow new bone. The plastic slowly degrades as the implant is replaced by newly grown bone.

The material is a blend of three types of plastics found suitable after hundreds of combinations of plastics were tested, to identify a blend that was

Stem Cells Against False Joints

Russian scientists started clinical trials of treating false joints by means of demineralized bone matrix with introduced mesenchymal stem cells of a patient.

False joints often occur as a complication during fractures of long bones, when splinters do not adhere, and cartilage layer forms between them. This layer is called false joint, and in this case, additional surgery is required to help a bone to heal.

Modern surgeons fight this problem with bone transplants, but bone recovery takes about one year. Possible solution is transplantation of mesenchymal stem cells of bone marrow, which can turn into various cells, including
