Final answer:
People with fractures in long bones or the pelvis are at risk for osteoporotic fractures that can result in serious complications such as deep vein thrombosis, pulmonary embolism, and pneumonia due to prolonged immobility.
Step-by-step explanation:
People with long bone or pelvic fractures are at increased risk for developing serious complications. Notably, they may face osteoporotic fractures, which can lead to debilitating conditions due to weakened bones and the danger of osteoporosis, particularly among the elderly. Among the potential complications are deep vein thrombosis (DVT), pulmonary embolism (PE), and pneumonia. These are caused by the immobility that often accompanies such fractures during the healing process. Long-term immobility can also lead to pressure sores, infection risks from urinary catheterization, and potentially life-threatening respiratory issues. The severity of these outcomes necessitates immediate and often surgical treatment, which comes with substantial healthcare costs and an increased rate of morbidity and mortality. It's paramount to manage such fractures immediately to avoid these serious complications.
