Since 1973, we experienced twenty patients with solitary bone cysts, such as eight cases in humerus, nine cases in femur, one case in tibia, and two cases in fibula.
In the fourteen patients who received curettage and bone graft, seven cases were rated as “healed”, three cases as “imcomplete healing”, and three cases as “recurrence”. One case failed to follow-up.
Imhauser's procedure was performed for two cases with bone cyst in femur, and all were healed.
For two cases of bone cysts in fibula, only curettage was performed, and one case recurred.
Two patients with pathological fracture of the humerus, received only cast-fixation.
One was rated as “healed”, the other was rated as “imcomplete healing”.
Conclusion
1) Curettage and bone graft had 21.4% recurrence rate, and in younger children it was more difficult to obtain sufficient amount of bone for grafting.
2) Imhauser's procedure dose not require curettage and bone graft, so this procedure has less burden upon little children.
