Abstract

Simple bone cyst is a typical cavitated injury which appears between the ages of 5 and 15 and is usually located in long bones’ metaphysis. It is limited by a membrane and filled with liquid, being considered a pseudocyst. The cyst is diagnosed as a casual finding in radiological tests as well as for causing pain or pathological fractures.Different aetiologies and pathogenies are postulated, of which sine or venous blockage with increased intracameral pressure is considered to be the most probable.The traditional treatment has been surgical curing and bone filling, with new less invasive techniques such as corticosteroid injection and cyst drainage recently appearing with good results. In this article we present a large simple bone cyst at the proximal end of the femur treated by intracavity puncture of corticosteroids.
