[Repair of bone defect with benign tumor by embryonic bone transplantation]
1First Orthopedic Hospital of Chengdu, Chengdu Sichuan, P. R. China 610031.
Objective:
To evaluate the clinical results of repair of bone defect by embryonic bone transplantation.
Methods:
From January 1994 to June 1999, 148 cases of bone defect were repaired by embryonic bone transplantation following alcohol treatment, there were 63 cases with bone cyst, 42 cases with fibrous dysplasia of bone, 26 cases with giant cell tumor of bone, and 17 cases with enchondroma among them. The maximal bone defect was 3.5 cm x 10.0 cm, while the minimal defect was 0.5 cm x 1.0 cm.
Results:
All of those bone defect with benign tumor were bone union used by embryonic bone transplantation after 3 months to 1 year of operation, the average healing course was 6.2 months, followed up 1 to 6 years, averaged 14 months, no tumor recurrence and no obvious local or system response were observed.
Conclusion:
Embryonic bone can be used as a good repairing material of postoperative bone defect of benign tumors, the clinical results are satisfactory.
