Introduction; The purpose of this study is to assess the efficacy of calcium sulfate as a bone graft substitute in the treatment of benign bone tumor.
Materials and Method : Between December 2000 and November 2001, 18 patients with a benign bone tumor were treated with crettage and the defects were filled with calcium sulfate (Osteoset:Wright Medical Co.USA) as a bone graft substitute. Average age was 28.4 years and mean follow up period was 12.3 months. Calcium sulfate mixed with autograft was used in 6 cases, calcium sulfate with allograft in 2 cases, and calcium sulfate alone was used in 10 cases, The degree of absorption of calcium sulfate and new bone formation at plain radiograph was analyzed at immediate postoperative and postoperative 3 months and 6 months follow up.
Results : At 3 months postoperatively, 92% of calcium sulfate was absorbed, and at 6 months postoperatively, 89% of new bone formation was observed. There was no difference in the resorption and new bone formation between the group using bone graft and the group osteoset alone, different preoperative diagnosis and even different locations. There was no complication.
Conclusion : Calcium sulfate(Osteoset) is a safe and effective bone graft substitute in the treatment of benign boen tumors, especially for the children in whom autograft is not recommandable.
