The Results of Multiple Aspirations and Injections of Unicameral Bone Cyst by Methyl Prednisolone Acetate

Overview

Evaluation of the efficacy of methyl prednisolone injection in treatment o f simple bone cyst to prevent all possible complications as pathological fractures and to avoid prolonged restriction of physical activity

unicameral bone cysts (UBCs) are benign, fluid-filled cavities that develop in tubular and flat bones (eg,humerus, femur). These cysts tend to expand and weaken the local bone,but they are not true neoplasms. In 1876, Virchow1 first described these lesions as cystic structures caused by abnormalities in local circulation. UBCs are also known as simple or solitary bone cysts. They occur almost exclusively in children and adolescents (up to 85% of cases), with a reported peak between ages 3 and14 years and the average age at diagnosis being 9 years. These lesions represent approximately 3% of all bone tumors and occur more commonly in boys than in girls (2:1). Several treatment options exist for unicameral bone cysts (UBCs), including observation, steroid injection, bone marrow injection, and Surgical procedures have ranged from simple curettage with autologous bone graft or allograft to sub periosteal resection with internal fixation and grafting .Treatment by multiple injection of steroids produce minimal surgical approach, no hospital stay, and very low morbidity. Three or four injections over a period of 12 month may be enough
