INTRODUCTION: The goal of this retrospective study was to compare the long-term results after implantation of the nonresorbable glass-ceramic material and transplantation of the cancellous allografts into the defects of long bones. METHOD: The bone cysts were excochleated and filled using granules of glass-ceramic material or cancellous allografts. Clinical, radiographic and scintigraphic examinations of 30 patients were carried out 2-14 years after their surgery. RESULTS: Though signs of complete incorporation allowing full weight-bearing capacity were observed on plain radiographs, we detected pain in six out of nine patients after diaphyseal implantation of nonresorbable glass-ceramic. We found an increase in (99) (m)Tc-methylene diphosphonate uptake on the delayed images in the area of glass-ceramic implantation, mainly in its diaphyseal location. In patients after bone transplantation, the cancellous allografts were completely integrated and the scintigraphic findings were physiological. CONCLUSION: The implantation of the nonresorbable glass-ceramic material into the diaphyseal defects of long bones is not suitable based on our study.
