Complications of open fractures of the lower limb

Joint may become permanently stiff if the fracture is through or near the joint

Bone or bone marrow may be infected by bacteria or fungi. If this becomes chronic it is called osteomyelitis. Pus is produced within the bone, creating an abscess that stops the bone from getting its blood supply. In chronic osteomyelitis the bone dies due to the loss of blood (avascular necrosis).

Avascular necrosis may also occur if the bones refuse to join back up again or take a long time in doing so.
