Ethicon Bone Wax (Product Code W31G) is a sterile hemostatic agent designed to control bleeding from exposed bone surfaces during surgical procedures. Supplied as 2.5 gram sterile units in a box of 12, this bone wax provides a pliable consistency that surgeons can easily mould and apply where needed to achieve mechanical hemostasis and minimize blood loss.

Unlike absorbable materials, Bone Wax is non-absorbable, offering a long-lasting physical barrier to bleeding. This waxy surgical aid is commonly used in procedures involving the skull, ribs, sternum, long bones, and other osseous tissues where conventional coagulation methods may be insufficient.

Bone Wax should be used by trained surgical professionals in appropriate clinical settings and is intended to support hemostasis; it does not contain pharmacologic clotting agents.
