A nonossifying fibroma of the femoral neck treated with curettage and dynamic hip screw with free fibular bone graft: a case report.

INTRODUCTION AND IMPORTANCE

Nonossifying fibroma (NOF) is a benign fibrogenic lesion that is related to dysfunctional ossification and one of the most common benign bone tumors in childhood with incidence rate of 30-40% of skeletally immature children.

PRESENTATION OF CASE

A 25-year-old female with left hip pain for the past 2 months, which was treated conservatively, presented with severe pain in the hip. X-ray showed a pathologic fracture in the neck of the femur with underlying lesion. MRI showed an osteolytic lesion in neck of the femur. Curettage of the lesion was done with free fibular bone graft and stabilized by Dynamic Hip Screw and specimen sent to pathology. The pathology report consisted with NOF. No-weight bearing for 8 weeks with physical rehabilitation were ordered and six months later the patient had a full range of motion and healed fracture.

CLINICAL DISCUSSION\CONCLUSION: This study revealed that the surgical treatment with bone graft for pathologic femoral neck fracture and underlying NOF allowed a quick return to mobility and can be fixed sufficiently to achieve excellent postoperative recovery.
