Bone hemostasis is the process of controlling the bleeding from bone. Bone is a living vascular organ containing channels for blood and bone marrow . [ 1 ] When a bone is cut during surgery bleeding can be a difficult problem to control, especially in the highly vascular bones of the spine and sternum .
External bleeding is generally described in terms of the origin of the blood flow by vessel type. The basic categories of external bleeding are: Arterial bleeding: As the name suggests, blood flow originating in an artery. With this type of bleeding, the blood is typically bright red to yellowish in colour, due to the high degree of oxygenation.
There are a range of characteristics of open fractures as the severity of the injury can vary greatly.

Both of these injuries are classified as open fractures. [7]
Hemostasis occurs when blood is present outside of the body or blood vessels. It is the innate response for the body to stop bleeding and loss of blood. During hemostasis three steps occur in a rapid sequence. Vascular spasm is the first response as the blood vessels constrict to allow less blood to be lost.

It is generally made of beeswax [1] with a softening agent such as paraffin or petroleum jelly and is smeared across the bleeding edge of the bone, blocking the holes and causing immediate bone hemostasis through a tamponade effect.
The stick is applied directly to the bleeding site. The high ionic strength promotes flocculation of the blood, and the astringent chemical causes local vasoconstriction. Before safety razors were invented, a styptic pencil was a standard part of a shaving kit and was used to seal shaving cuts. [ 13 ]
