What is the most common site of involvement for acute suppurative osteomyelitis?

Acute suppurative osteomyelitis seeds into bone most readily where the blood supply to the bone is rich and the flow is slow, a situation typical in the metaphysis of long bones. The femur has a large metaphyseal region with substantial marrow and active blood supply, which makes it a prime site for bacterial seeding and pus formation. This combination explains why the femur is the most commonly involved site in this condition. In contrast, the skull is resistant because cortical bone limits marrow spaces, and while the humerus and tibia can be affected, they appear less frequently than the femur in many cases.
