ABSTRACT
Objective To study far femoral malignant bone tumor salvage limb treatment with allogeneic heterotopic half-joint transplantation and the use of GSH nail Methods Eleven cases with far femoral malignant bone tumor were administered tumor resection,transplanted with allogeneic heterotoeic bone half-joint,and fixed with GSH nail Results Nine out of the 11 cases were followed up.None of them had infection,rejection or heterotopic bone fracture.All of them can move with walking after 6 months.The effects of surgery was rated as excellent for 3 cases,fine for 4 cases andbad for 2 cases according to Mankin's rating criteria.Conclusion Salvage limb treatment for bone tumor can improve patients' quality of life.Allogeneic heterotopic bone,with rich source and acceptable joint surface,is a good graft for the treatment of bone defect after bone tumor resection.
ABSTRACT
Heterotopic bone formation is a complication which occurs in 0.6 to 61.7% of patients after total hip replacement arthroplasty. We reviewed 4 patients (8 hips) who received postoperative irradiation on their hips for prevention of heterotopic bone formation in the Department of Therapeutic Radiology, Seoul National University Hospital from January 1981 through August 1985. Radiation therapy was started 6 to 10 days postoperatively with the dosage of 2,000 cGy given in 10 fractions. As a result, 7 hips had Grade 0 and 1 hip had Grade 1 heterotopic ossification according to modified Brooker system. Our result and review of the literatures strongly support that the postoperative radiotherapy is effective for prevention of heterotopic bone formation in high risk group.
