Abstract
A case undergoing implantation of autogenous bone and hydroxyapatite for the bone defect produced after curettage of infantile solitary bone cyst is reported.
The patient was a 13-year-old boy. On 14 October 1990, he suffered from a fracture of his right femur when he was playing soccer. By an X-ray examination, he was diagnosed as a pathological fracture caused by bone tumor, and its curretage and osteosyndesis were carried out in another hospital. Pathological diagnosis of that tumor was solitary bone cyst.
Since then, he was observed periodically in our hospital. But gradually, the size of the tumor shadow on the X-ray photograph became enlarged. And so we performed the re-operation on 29 July 1991. After removal of a bone plate, we performed curettage of the bone tumor again and implanted the autogenous bone and hydroxyapatite into the bone defect. On the X ray photograph on October 1992 (1 year 2 months after the second operation), induced cancellous bone was observed around the hydroxyapatite.
At present, he has no clinical symptoms and is enjoying much sports activities aggressively.
Hydroxyapatite seems to be very useful for supplement of the bone defect, particularly in infantile cases.
