[Surgical treatment of pertrochanteric femoral benign tumors in children].

Introduction: Disclosure of the tumor area intertrochanteric femur occurs mostly at the time of pathological fracture. Detection of changes can also be made in conjunction with x-ray of the hip joint such as the hip injury. The purpose of this study was to present the treatment of benign tumors of the intertrochanteric area in children and adolescents.

Materials and methods: From 1. 01. 2002 to 31. 12. 2009 13 patients were treated with benign tumors of the femur intertrochanteric area, including 10 with pathological fractures in the background. Average age was 9.8 years (5-13 years). There were 11 boys and 2 girls. The procedure was performed with resection of the tumor,histopathology, allogenic bone grafting, the femur was fixed using locked plate (10 patients) or angular plate (3 patients).

Results: The mean observation time was 62 months (24-94 months). Histopathology examination showed a simple cyst in 7 patients, aneurysmal cyst in 2 patients, and fibrous dysplasia of bone in 4 patients. Bone consolidation was achieved in 10 patients after an average of 4 months (3-5 months) after surgery, as determined by X-ray examination and clinical examination. In 3 cases there was a recurrence of the tumor, 2 patients with fibrous dysplasia after 4 months and 6 months after surgery were found in X-ray partial resorption of bone graft >25%, and 1 patient after 4 months presented fatigue fracture at Adams angle. After re-treatment complete bone consolidation was achieved in this group after an average of 4 months (2.5-5 months) from the second surgery. 1 patient with aneurysmal cyst in 11 month after surgery, presented femoral infection, sequestrum and plate were surgically removed, antibiotic therapy was used and the inflammatory process was stopped.

Conclusion: Surgical treatment of benign tumors of the intertrochanteric area of the femur gives good results if it is carried out by a complex surgery (resection of the tumor - bone graft - osteosynthesis).
