The musculoskeletal System - A Case Study - Short Answers - Essay ExampleThe wounds can be brusk or closed. Open wounds are common be subject the shaft of the tibia is just below the skin and subcutaneous tissue and is not covered with much spongelike tissue. Most of the tibial shaft fractures are associated with fibular fractures too. In Julia, the fracture occurred due to high speed accident. The fibula was however not involved and the wound was closed.The of import sources of pain in Julia are the site of fracture, skin and subcutaneous tissue and the muscles surrounding the tibia. Fracture induces significant amount of inflammation and release of inflammatory mediators with gravel pain, swelling, warmth and redness. During fracture, hematoma may be formed which can also cause pain (Rosenberg, 2007).Inflammatory cells, phagocytes and fibroblasts have a major role in the healing process of the fracture. Fracture causes formation of hematoma and a blood clot gets formed between the broken fragments of the fracture. After the initial few days following fracture, blood vessels grow within the clot. These blood vessels allow accumulation of phagocytes to the area which help in the removal of dead tissue. The blood vessels also cause pouring in of fibroblasts which multiply in the walls of the blood vessels and produce collagen fibres. These fibres replace the blood clot. The fibroblasts also lay down bone matrix or atomic number 20 hydroxyapatite which helps in the transformation of collagen to bone (Rosenberg, 2007).Factors which promote wound healing in Julia are immobilization, good nutrition, young age and absence of infection (Rosenberg, 2007 Konowalchuk, 2005 and Norvell, 2009). Immobilization is in truth essential to promote fracture healing. This is because, any movement of the fragments of the fracture hinder the process of healing. Movement disturbs the formation of clot and invasion of blood vessels within the clot. hang in the formation of bloo d vessels prevents invasion of fibroblasts essential for deposition of collagen and bone
