What should you know about phalanx osteomyelitis?

The phalanges are the small bones of the fingers and toes. Infection can reach one through a wound, puncture, nearby soft-tissue infection, surgery, or spread through the bloodstream. Pain, swelling, warmth, redness, drainage, reduced movement, or fever may occur, although symptoms vary. A clinician may combine an examination with blood tests and imaging; a sample may sometimes be needed to identify the organism and guide treatment.

Arrange prompt medical care if osteomyelitis is suspected, especially when there is an open wound, diabetes, poor circulation, or an implanted device. Keep any wound clean and covered, avoid squeezing or probing it, and take prescribed treatment exactly as directed. Do not use leftover antibiotics. Treatment may involve antibiotics, wound care, drainage, or surgery depending on the infection and bone damage. Bone grafting may be considered in selected reconstruction plans; read about [Bone Grafting](/treatments/trauma-and-fracture-care/bone-grafting/).

Seek urgent care for fever with rapidly spreading redness, severe or escalating pain, pus, red streaks, confusion, or a finger or toe becoming pale, blue, or cold. Prompt assessment is also needed when a wound is deep, a bone is visible, movement suddenly worsens, or symptoms return after treatment.

Ask which bone and tissue are involved, what tests are needed, whether a culture is appropriate, and how long treatment may take. Ask how the wound should be dressed, which movements are safe, and whether surgery is being considered to remove infected or damaged tissue.
