The surgical treatment for fibrous dysplasia (FD) of bone is problematic due to its variable clinical courses. And multifarious surgical treatment options have been reported while no consistent view can be reached. Therefore, we reviewed a series of 22 patients (11 males and 11 females; mean age 28.4 years, range 15-48 years) with FD between December 2011 and July 2015. Fourteen patients had monostotic fibrous dysplasia (MFD) and eight patients had polyostotic fibrous dysplasia (PFD) with nine lesions. All patients were followed up from 15 to 58 months with an average of 26.0 months. Functional and radiographic outcomes were recorded. In the MFD group, four patients were treated with curettage and bone grafting without internal fixation and nine were treated with curettage and bone grafting with internal fixations. Osteotomy and intramedullary (IM) nail was applied in one patient with serious deformity. In the PFD group, three deformity lesions were treated with osteotomy and proximal femoral nail anti-rotation (PFNA). IM were also applied in six large lesions to treat fracture or prevent deformity. One lesion in tibia were treated with only curettage and bone graft. No complication was observed in MFD group and satisfactory union and functional outcomes acquired during follow-up period. In the PFD group, the spiral blade cutting out from femoral head in PFNA was observed in one patient and treated with revision surgery. No other complication occurred, and satisfactory radiological and functional outcome were observed. The severity of both MFD and PFD are related to size, site and of the lesion. The goal of the surgery is to eliminate pain, correct deformity and treat pathological fracture. Curettage, bone grafting with internal fixation is recommended for treating large lesions with deformity or high pathological fracture risk. PFNA or IM nail is prior in osteotomy with better clinical outcome.
