Clinical outcome following surgical intervention for a solitary bone cyst: emphasis on treatment by curettage and steroid injection

Steroid injection remains a useful method for treating solitary bone cysts owing to its low invasiveness. The very favorable results achieved in the five calcaneus cases following a single steroid injection may be attributable to curettage. Regardless of the relatively small number of cases, the different prognosis between long bones and the calcaneus following the same procedure suggests a varying pathogenesis and/or etiology among solitary bone cysts.
