Isolated Talar Metastasis of Renal Cell Carcinoma Treated With Tibiocalcaneal Arthrodesis Using an Ilizarov External...

Acrometastases to the feet are exceedingly rare. We report a case of isolated talar metastasis from renal cell carcinoma successfully managed through surgical excision and reconstruction with Ilizarov external fixation. A 65-year-old male presented with a six-month history of right ankle pain. Radiographs revealed an osteolytic lesion in the talus. An incisional biopsy confirmed the diagnosis of metastatic renal cell carcinoma. Systemic evaluation showed no recurrence in the right kidney or metastases beyond the right talus. En bloc resection of the talus was performed via an anterior approach, followed by tibiocalcaneal arthrodesis using Ilizarov external fixation. At the four-year follow-up, the patient remained pain-free while walking and showed no evidence of recurrence or additional metastases.
