Distal fibula resection in osteochondroma.

We evaluated the effects of distal fibula resection on the ankle function in a patient with osteochondroma. Osteochondroma is a benign tumour which localizes in the metaphysis of the long bones, in the knees and in the shoulders. Although it does not usually cause any symptoms in children under 10 years, we had a 4-year-old patient with a painful swollen ankle with limited motion. Resection of the lateral malleolus did not affect ankle function and he remained pain-free in daily activities during a 2.5 year follow-up period.
