Which medical condition increases the risk of osteomyelitis?

A. Osteoporosis: Rationale: Osteoporosis is a metabolic bone disease that affects bone density, but it does not directly increase the risk of bone infection. B. Osteogenesis imperfecta: Rationale: This is a genetic disorder of brittle bones, but it does not inherently increase infection risk like osteomyelitis. C. Diabetes: Rationale: Diabetes, especially with poor glucose control, impairs circulation and immune function. Chronic wounds (e.g., foot ulcers) provide a portal of entry for pathogens leading to osteomyelitis. D. Cancer: Rationale: While immunosuppression from cancer or its treatment may increase infection risk, it is not as directly linked to osteomyelitis as diabetes.
