We studied 23 patients (25 bones) with enchondromata of the hand which were treated with simple curettage without bone grafting. The cortical window was replaced in 18 bones (group A), whereas it was not replaced in six bones (group B). In one bone, only half of the cortical window was replaced. Local recurrence was not seen in any patient. Although bone grafting was not performed, new bone formation was observed in all the patients. Radiographic and functional results were excellent in most bones. Restoration of the continuity of the cortex was seen at 3 (range, 1.5-4) months in group A and 8 (range, 6-12) months in group B. This restoration is important for the recovery of mechanical strength and we therefore consider that the cortical window should be replaced, unless this is impractical.

We conclude that simple curettage without bone grafting can be one of the standard surgical treatments for enchondromas of the foot.
