We have performed cryopreserved allografting procedures for benign bone tumors in childen since 1993. The results were investigated by assessing radiographic findings, the clinical outcome, and conplications.
There were 11 patients, and seven were boys and four were girls. The mean age at operation was 13 years old. The mean follow-up period was 2 years. The sites of tumors were humerus in 1 patient, femur in 6, fibula in 2, and tibia in 2. All patients received cryopreserved allografts affer curettage of the lesion.
The mean operative time was 2.5 hours and blood loss was minimal in the majority of cases. There were no serious complications (e. g., infencion of the grafts) in any of the patients. A mean interval to bone union was 10 weeks and that to homogenity was 6 months. Remodeling of grafted sites was observed in all patients.
In summary, allografting caused minimal blood loss and produced satisfactory remodeling, making it a useful technique for children, because their own bone brafting would be invasive to them.
