Nonossifying fibroma of the lower femur with genu valgum: a case report

Nonossifying fibroma is common in children and adolescents, and nonossifying fibroma with genu valgum is rare in the clinic. This article evaluated the effectiveness of treatment in a case of nonossifying fibroma of the lower femur with genu valgum. A 16-year-old girl complained of pain in the lower part of her right thigh for one year. She was diagnosed as non ossifying fibroma of the right femur with secondary valgus deformity of the right knee, and was treated in our hospital. We performed curettage, bone grafting and internal fixation,and corrected the valgum deformity at the same time. The patient's incision healed well, the pain was disappeared, and the mechanical axis of lower limbs was corrected. No tumor recurrence was found on X- ray examination one year after operation, and the fracture end was healed. The patient could walk normally, and she was satisfied with her limb function. Nonossifying fibroma with genu valgum is rare in the clinic. The patient was satisfied with our treatment, which achieved a good curative effect.
