Abstract

Twenty eight patients with simple bone cyst that were treated by aspiration and percutaneous autogenous bone marrow injection were reviewed to evaluate the treatment outcome. There were 18 boys and ten girls. Their mean age was 10.9 ± 2.75 years. Single injection was performed for 16 patients; the rest had double or triple injections. There were no operative complications. The mean follow-up was 34.7 ± 6.87 months. The procedure succeeded in obtaining healing in 23 cysts (82%). Cysts with index of more than five and cortical thickness of less than 1 mm were significantly prone to pathological fractures and had significant poor results after treatment. Our results suggested that autogenous bone marrow injection is a safe and effective treatment method for simple bone cysts, but sometimes repeated injections are necessary. Cyst index and cortical thickness are good indicators for cyst aggressiveness and good predictors for treatment outcome.

Résumé

Vingt huit patients avec un kyste osseux solitaire furent traités par aspiration suivie de l’injection per cutanée de moelle osseuse autologue. Il y avait 18 garçons et 10 filles d’age moyen 10,9 +−2,75 ans. Seize patients ont euune simple injection, les autres 2 ou 3 injections. Il n’y a pas eu de complication. Le suivi moyen était de 34,7 +− 6,87 mois. La cicatrisation fut obtenue pour 23 kystes. Les kystes avec un index de plus de 5 et une épaisseur corticale de moins de 1 mm était plus sujet aux fractures et avaient un moins bon résultat. Ces résultats suggèrent que l’injection de moelle osseuse autologue est une bonne méthode de traitement des kystes osseux, demandant quelquefois des injections répétées. L’index kystique et l’épaisseur corticale sont prédictifs de l’efficacité du traitement.
