Direct extension, as its name implies, occurs when bone or soft tissue comes into contact with a directly adjacent infection leading to a soft tissue abscess or osteomyelitis. For the spine, this route is typically seen adjacent to a decubitus ulcer where there is adjacent osteomyelitis. An infection of the disc space can extend into the adjacent paravertebral soft tissues and produce psoas muscle abscesses. Direct extension is also the mechanism for epidural abscess involvement cranial or caudal to the site of disc space infection. This route can also be seen for an intramedullary spinal cord abscess where the infection occurs through congenital dysraphism or a dermal sinus tract. Lymphatic spread is of limited importance in the spine relative to the much more commonly seen direct extension and hematogenous spread. Lymphatic spread may be seen in cases of retroperitoneal node enlargement from pelvic or abdominal primary neoplasms. Hematogenous Spread Hematogenous spread is the major pathway of infection spread to the axial skeleton. Which route is more important (arterial or venous) is controversial. The arterial route is classically more important for spread of spinal
