Summary
We carried out a retrospective review of 75 children with unicameral bone cysts, who had sustained 52 pathological fractures, to determine which cysts were likely to be at risk and whether healing was accelerated after a fracture. Most lesions were in the metaphysis of a tubular bone, the commonest sites being the the upper part of the humerus and femur. The percentage of bone occupied by the cyst in the transverse plane was more than 85% in both anteroposterior and lateral radiographs in every case of pathological fracture. In most cases, the cyst recurred and sometimes became large without any acceleration of healing.
Résumé
Nous avons conduit une étude rétrospective de 75 malades porteurs d'un kyste solitaire des os afin de déterminer quels sont les types de kystes comportant un risque de fracture et si cette fracture peut accélérer la guérison du kyste. Soixante-quinze patients avec 52 fractures pathologiques ont été revus. Les lésions siègeaient en majorité au niveau de la métaphyse des os longs. Elles étaient localisées essentiellement à l'extrémité proximale de l'humérus et dans la partie supérieure du fémur. La surface occupée par le kyste dans le plan horizontal dépassait 85% sur les radiographies de face et de profil chez tous les patients présentant une fracture pathologique. Dans la plupart des cas l'évolution se fit vers la récidive et même vers l'extension du kyste originel, sans accélération du processus de guérison.
