Abstract

PURPOSE
This study evaluated the results of conservative treatment for simple bone cyst.
MATERIALS AND METHODS
We studied 126 cases of simple bone cyst, which were treated by observation or steroid injection from February 1990 to May 2010. Their mean age at diagnosis was 14 years (+/-9 years, 2-60 years) and the mean follow-up duration for this study were 41 months (+/-37 months, 12-159 months). Observation and steroid injection was applied for conservative management of simple bone cyst and results was scored by modified Neer classification.
RESULTS
31 cases (24.6%) were treated by observation and 95 cases (75.4%) were treated by steroid injection. The 95 patients were treated by a mean of 1.1 (+/-0.9, 0-4) steroid injections and a single steroid injection was given in 65 cases (51.6%). The 102 cases (80.9%) were resulted in modified Neer classification I and II which could be considered as healing of simple bone cyst.
CONCLUSION
Conservative management can be considered as an initial treatment for simple bone cyst with good result.
