Abstract: Osteomyelitis is an infectious inflammation of deep tissues caused by bacterial infection. Persistent infection will lead to dissolution and necrosis of bone tissues. At present, it is difficult to cure osteomyelitis completely by surgical treatment and antibiotic treatment, and long-term use of antibiotics will make bacteria resistant, which makes it more difficult to treat osteomyelitis. Photodynamic antibacterial chemotherapy(PACT)is a new method of anti-infection treatment. Infection caused by drug-resistant bacteria has a good curative effect. This paper introduces the causes of refractory osteomyelitis, the advantages of PACT in the treatment of osteomyelitis and the recent experimental research progress. With the in-depth study of PACT for osteomyelitis, PACT is expected to become a new method to completely cure osteomyelitis.

Key words: photodynamic antibacterial chemotherapy(PACT), osteomyelitis, photosensitizer, multi-drug resistant bacteria
