PATHOLOGY

Detailed explanation-1: -Inflammation starts immediately after the bone is fractured and lasts for several days. When the bone is fractured, there is bleeding into the area, leading to inflammation and clotting of blood at the fracture site. This provides the initial structural stability and framework for producing new bone.

Detailed explanation-2: -Inflammatory Phase: starts at the time of injury and lasts 1-2 weeks. Bleeding around the fracture organizes into a fracture hematoma or clot on the bone ends.

Detailed explanation-3: -Inflammatory Phase An inflammatory response occurs immediately following bone fracture. The trauma leads to blood vessel rupture inside and surrounding the fracture site, resulting in a hematoma.

Detailed explanation-4: -Inflammatory phase (duration: hours–days): Broken bones result in torn blood vessels and the formation of a blood clot or haematoma. The inflammatory reaction results in the release of cytokines, growth factors and prostaglandins, all of which are important in healing.

Detailed explanation-5: -Fractures typically cause swelling, but swelling may take hours to develop and, in some types of fractures, is very slight. When muscles around the injured area try to hold a broken bone in place, muscle spasms may occur, causing additional pain. Bruises appear when bleeding occurs under the skin.
