Clinical Study of Solitary Bone Cyst

School of Allied Medical Sciences, Kagoshima UniversityThe optimum treatment of solitary bone cyst (SBC) remains controversial. We have treated 24 patients with SBC using five kinds of treatment in the past 10 years; intralesional steroid injection, shunt therapy, percutaneous trepanation, drainage by cannulated screw, and curettage and bone grafting. The rates of healing or improvement by a single therapy, as evaluated by roentogenograms were 53%, 71%, 80%, 100%, and 67%, respectively. The final results of 24 cases were as follows; healed in g cases, improved in 13 cases, and unchanged in 2 cases. Regarding the 17 cases of long tubular bone; healed in 5 cases, improved in 11 cases, and unchanged in 1 case. In this series, most of the cases improved, however, the rate of complete healing was not high. We will therefore have to treat SBC with more successful methods.
