Final answer:
Hematogenous osteomyelitis is an acute condition caused by bacteria entering the bloodstream and primarily affecting children. Chronic osteomyelitis is a long-term infection caused by a primary bone infection and commonly occurring in adults.
Step-by-step explanation:
Hematogenous osteomyelitis and chronic osteomyelitis are two different forms of bone infection. Hematogenous osteomyelitis is typically caused by bacteria spreading through the bloodstream and primarily affects children. It is an acute condition that results from a bacterial infection. In contrast, chronic osteomyelitis is a long-term infection that usually originates from a primary bone infection and is commonly caused by direct bone injury in adults. It can result in bone loss and may require surgical intervention.
