Induced membrane technique and intramedullary beaming for the extensive bone defect of the talonavicular joint: A case report and literature review.

Cases involving both the induced membrane technique (IMT) and intramedullary beaming (IB) are generally rare. Here, we report such a case in an 83-year-old man who presented with 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 (RA). Therefore, the patient underwent both IMT and IB for the extensive bone defect in the talus and navicular regions caused by seronegative RA. The patient exhibited satisfactory short-term outcomes.
