Brisement Forcé With Controlled Collapse in Treatment of Solitary Unicameral Bone Cyst

Abstract

SOLITARY unicameral cyst is an uncommon disease of bone. When present, however, treatment may be problematical because of both the size and the location of the lesion. Recurrences have been noted after all forms of surgical treatment. Healing has occasionally occurred after fracture although, in the usual case, such an injury does not guarantee that the cyst will consolidate or disappear. Solitary cysts are found adjacent to or in apposition with epiphyses, most often those of the proximal humerous or the proximal femur. Because of the danger of growth arrest when operating in juxta-epiphyseal tissue, as well as the increased incidence of recurrence in cysts in this location, surgery is often difficult and unsuccessful. Where bone grafting is the technique of choice, substantial donor tissue is often required to fill the cyst. When autogenous bone is used, this may entail opening into several body sites to obtain adequate tissue. The
