title: Ollier's disease treated with grafting using alpha-tricalcium phosphate cement. A case report.
abstract: Ollier's disease is a rare disorder characterized by multiple enchondromas with a unilateral predominance, especially in fingers in early childhood. We experienced a case of Ollier's disease treated four times with simple curettage from the age of 2 years and alpha-tricalcium phosphate cement grafting at the age of 21 years. The forth curettage was performed when the patient was 15 years old and preoperative X-rays had shown remarkable finger deformities. Postoperative casting of the involved joints was necessary to prevent fractures but led to some finger contractures. Following X-rays demonstrated incredible improvement of the appearance. This suggests that simple curettage alone at an early stage of Ollier's disease provide cosmetic improvement. At the age of 21 years our patient showed enlargement of the intramedullary finger lesions again. Some lesions seemed to be impending pathological fractures. This time we chose alpha-tricalcium phosphate cement to fill the cavities after curettage had been carried out. Harvesting a large amount of autologous bone was not required. All activities of daily life could be resumed immediately after surgery and none of the finger joints showed further restriction of motion. X-rays taken three years after the operation showed new bone ingrowth surrounding the material with little evidence of absorption. To our knowledge, this may be the first case of Ollier's disease treated with artificial bone grafting reported in the English literature.
