What happens if osteomyelitis left untreated for much longer?

Condition analysis:
All bone infection must be debrided and dead bone taken out. The patient should also be started on IV antibiotics immediately. I would recommend seeing a wound specialist and also starting with hyperbaric oxygen therapy to help with healing. If this has not been treated at all, then I would go to the emergency room ASAP and get started with treatment.

Instructions:
Debridement: In case the bone damage is extensive, then the diseased bone and other tissue need to be removed. Such a procedure is called debridement. Open space left due to removal of bone tissue needs to be packed with packing material (antibiotic-permeated cement) or bone graft.

This allows new bone tissue to form in that place. The bone used in grafting can be harvested from somewhere else in the body, usually the hip. If the surrounding tissue has been excised, then skin and muscle may need to be grafted.
