Abstract

Solitary bone cyst commonly occurs in growing age, and at the juxta-epiphyseal region of the metaphysis of long bones such as femur, tibia and humerus and it is rarely seen in short tubular and flat bones. The cause of solitary bone cysts is controversal. In this paper, a case of solitary bone cyst occurred in the talus was reported. The case was a 17-year-old high school girl who complained of intermittent pain on the right ankle for two months. Tomography showed a well demarcated thumb tip sized radiolucent cavity on the posteromedial aspect of the right talus. Radical carettage followed by massive chip bone graft was performed. The finding at operation showed a cavity occupying posterior one fourth of the body of the talus. The wall of the cavity was thin cortical layer of the bone and cartilage like papes. Content of the cavity was small amount of yellowish fluid and tiny amount of granulations attached to the wall. The diagnosis was confirmed with roentgenological examination, operative findings, and microscopic examination.
