Successful nonsurgical therapy of a diabetic foot osteomyelitis in a patient with peripheral artery disease with almost complete radiological restoration

Background Diabetic foot ulcer (DFU) is a common complication in patients with diabetes mellitus (DM) and can consequently lead to soft tissue infection and osteomyelitis. Case presentation We present a case of a 68-year-old man with a history of Type 2 DM and symptomatic peripheral artery disease, referred to our hospital due to an infected lower extremity DFU. Cultures revealed methicillin-resistant Staphylococcus aureus and Stenotrophomonas maltophilia . There was a significant increase of inflammatory marker levels and plain X-rays revealed osteomyelitis. He underwent lower extremity angioplasty for the restoration of the blood flow. He received targeted intravenous antibiotic therapy for 2 weeks and continued ciprofloxacin along with clindamycin per os for 10 more weeks as outpatient. Conclusion As a result, the patient presented almost complete healing of his DFU, reconstruction of osteomyelitis defects in X-ray and complete restoration of his foot functionality only 4 months after the end of the treatment. This case demonstrates a DFU complicated by osteomyelitis which resolved medically and nonsurgically, with the exception of surgical restoration of the blood flow.
