The Dissolving Bone Screw - A magnesium screw can hold broken wrist bones together while they heal, then gradually dissolve inside the body. This innovative implant supports bone repair, allows new bone to grow, and eliminates the need for a second surgery to remove it.

MAGNESIUM SC MAGNESIUM SCREW When you break a small bone in your wrist, a surgeon can hold it together with a screw made of magnesium. As the screw turns deeper into the bone, the two broken pieces are pulled tightly together. It has no head, and the threads at its front are spaced wider than the threads at its back. With each turn, the front advances faster than the back, closing the gap between the fragments so the bone can heal under steady pressure. Over the next one to two years, the body slowly breaks the magnesium down. As it dissolves, small bubbles of hydrogen gas form, and new bone grows into the space it leaves. No second surgery is needed to remove it.
