ABSTRACT
Prosthesis of femoral head is a common surgical procedure, but the diagnosis of infection associated with the prosthesis remains difficult. We diagnosed non-invasively methicillin resistant Staphylococcus aureus (MRSA) infection of prosthesis of femoral head with Bi-Digital O-Ring Test (BDORT). BDORT uses the resonance phenomenon between 2 identical substances, and electromagnetic field principle. The method can non-invasively detect viral & bacterial infection. Accuracy of the BDORT findings was confirmed through bacterial culture & sensitivity test to antibiotics. Patient was successfully treated with operation of evulsion of the prosthesis of femoral head and administration of antibiotics and Cilantro. The drug compatibility was tested with BDORT. BDORT was an effective technique for non-invasively detecting infection of prosthesis and selecting the most effective antibiotics.
