Normally, an inflammatory process starts at the site of trauma and the presence of debris. "At fracture sites, the hematoma serves as the basis for a fibrin network into which granulation tissue grows. Many new capillaries extend into this tissue, and phagocytic cells (for removing debris) and fibroblasts (for laying down new collagen fibers) migrate to it," (VanMeter and Hubert, 2015). Hypertension is a persistent elevation of blood pressure, which would make it more difficult for blood to flow to to the fracture and stimulate proper bone and tissue healing (VanMeter and Hubert, 2015).
Five stages of fracture healing: Hematoma, granulation tissue, procallus, bony callus, and remodeling. Fracture healing is delayed in older adults with circulatory problems, diabetes mellitus, or nutritional deficit (VanMeter and Hubert, 2015).
After the initial surgery they noticed EAC's surgery site was not healing properly. The orthopedic surgeon decided to take her in for a wound debridement and to place a wound vac. She continues to take antibiotics as a preventative measure against infection.
Being a post-menopausal white woman also means she is at a much higher risk for lower bone density, and therefore a much higher chance of poor bone healing (VanMeter and Hubert, 2015).
