Bone-knitting polymer

Bone-Knitting Polymer is a material used for medical purposes by the UNSC. It is injected into a wound through a cauterized incision, where it can heal a fractured bone.

It is likely that it works in essentially the same way as the bones heal naturally, perhaps creating a small "cast" like human cartilage to set the bone whilst stimulating the osteocytes to reproduce at a higher rate than is normal.

Bone-knitting polymer was used on Staff Sergeant Avery Johnson after he was knocked unconscious by Shipmistress Chur'R-Yar aboard the Minor Transgression.

Trivia

• The amount of time it takes for the polymer to take affect is unknown, but Johnson was unconscious for quite a while after the destruction of the Kig-Yar ship.
