Case Report
Cases involving both the induced membrane technique and intramedullary beaming are generally rare. Here, we report such a case in an 83-year-old man who suffered from left midfoot pain. Pyogenic arthritis was suspected based on clinical findings, and curettage was performed, revealing an extensive bone defect. The patient was clinically diagnosed with seronegative rheumatoid arthritis. Therefore, the patient underwent both induced membrane technique and intramedullary beaming for the extensive bone defect in the talus and navicular regions caused by seronegative rheumatoid arthritis. The patient exhibited satisfactory short-term outcomes.
