We treated 19 cases of unicameral bone cysts with methylprednisolone acetate (MPA) from January 1988 to December 1995. We evaluated the effect of MPA injections through simple follow-up radiographs according to Oppenheim´s classification and retrospectively reviewed the sites of cyst, age of the patients at diagnosis, the incidence of pathologic fracture, cystic nature, and cystic proximiy to the growth plate. We then analyzed the relationship between these variables with the results of MPA injections. According to Oppenheim´s classification, the results with the use of MPA injections were as follows : healed in six cases, improved in seven cases, incomplete obliteration in five cases and recurred in one case. If healed and improved were considered satisfactory results, then 13 cases(68.4%) were satisfactory at the last follow-up. Sites of cyst, age of the patients at diagnosis, incidence of pathologic fracture, cystic nature and cystic proximity to the growth plate appeared not to influence the results of MPA injections statistically. On these data, we thought that the treatment of unicameral bone cysts with MPA injection was the most effective first choice of treatment before operative options such as curettage and bone graft.
