Prostaglandin Levels in Unicameral Bone Cysts Treated by Intralesional Steroid Injection

Abstract
The etiology of the unicameral bone cyst remains undefined. Likewise, the treatment of the cyst has had proponents suggesting procedures ranging from decompression to diaphyseal resection. The use of intralesional steroids has gained popularity since its introduction in 1979 by Scaglietti. We present the results of aspirations of seven cyst, with serial measurements of prostaglandin levels in five cases, and suggest that the antiprostaglandin action of the steroid forms the rationale for treatment of the simple cyst.
