Osteomyelitis is an inflammation of bone caused by pus-forming bacteria that enter through a wound or are carried by the blood. Often the blood-rich ends of the long bones are invaded, and the infection then spreads to other regions, such as the bone marrow and even the joints. The use of antibiotics has greatly reduced the threat of osteomyelitis.

Tuberculosis may spread to bone, especially the long bones of the arms and legs and the bones of the wrist and ankle. Tuberculosis of the spine is Pott disease. Infected vertebrae are weakened and may collapse, causing pain, deformity, and pressure on the spinal cord. Antibiotics can be used to control tuberculosis as long as the strains are not resistant to these drugs and the host is not weakened by other diseases.
