Within the first four days after trauma, the fracture haematoma develops an osteogenic potential that enables bone formation in ectopic locations when explanted and consequently secondary fracture healing (Mizuno et al. 1990).

Does a hematoma block hurt?

The disadvantages of the hematoma block include the discomfort and anxiety resulting from injecting into the fracture site, and the potential for a rare complication. Extremity fractures, when displaced or angulated, generally result in the formation of a hematoma between the fracture fragments.

What is a fracture hematoma?

The inflammatory phase — also called the fracture hematoma formation — begins immediately after a fracture occurs. During this phase, bleeding and inflammation begin in the fracture site. The blood clots to form a hematoma at the bone edges, providing the framework for bone regrowth to occur.

Why are hematomas so painful?

Intramuscular hematomas can be very painful due to the amount of swelling and inflammation. Some muscles are surrounded by tough bands of tissue. If enough bleeding occurs, the pressure within these compartments can increase to the point that “compartment syndrome” can occur.

How long does it take for hematoma to heal?

Gradually the blood in the hematoma is absorbed back into the body. The swelling and pain of the hematoma will go away. This takes from 1 to 4 weeks, depending on the size of the hematoma. The skin over the hematoma may turn bluish then brown and yellow as the blood is dissolved and absorbed.
