Abstract:
PURPOSE: The purpose of this study is to observe unicameral bone cyst (UBC) outcome after the fracture has healed and if there is any identifiable prognostic factors. MATERIALS AND METHODS: 13 UBC patients with pathologic fracture from 2001 to 2010 were reviewed. The mean follow up were 26 months (3-90 months). There were 11 male and 2 female patients and the mean age of the patients were 10.2 years old (6-16 years). 9 involved proximal humerusand 2 involved humerus shaft and 1 involved proximal femur and 1 involved proximal tibia. The treatment of UBC fracture was conservative cast application to heal the fracture initially, and 1 patient was treated with primary auto bone graft and open reduction with internal fixation. 5 patients were treated with steroid injection during follow up period and 2 patients with auto bone graft. We analyzed the change of UBC during pathologic fracture healing period and prognostic factor about age, the size of UBC, the involvement of physis. RESULTS: The mean duration of the fracture healing was 8.2 months. Complete healing were occurred at 4 patients (31%). No statiscal difference was checked with age about UBC healing (p=0.42). But, more larger size about UBC and more closer to physis, the healing was difficult (p=0.05, p=0.03). CONCLUSION: While pathologic fracture of UBC was possibly healed, active treatment should be applied especially those cysts that involvescloser area of the physis or large size.
