[Particle impaction bone graft and plate internal fixation for the treatment of proximal femoral bone tumor or tumor lesion].

OBJECTIVE: To evaluate the clinical feasibility of particle impaction bone graft and plate internal fixation for the treatment of proximal femoral bone tumors or tumor disease. METHODS: From January 2013 to January 2016 a total of 26 cases of the proximal femur bone tumors or tumor lesions, neither pathological fracture, were retrospectively analyzed, including 12 males and 14 females with an average age of 34.2 years old ranging from 8 to 62 years old. The pathologic result involved fibrous dysplasia in 11 cases, bone isolation bone cyst in 7 cases, giant cell tumors of bone in 3 cases, aneurysm sample bone cyst in 3 cases, non ossifying fibroma in 1 case, benign fibrous histiocytoma in 1 case. No biopsy of the lesion was performed before the operation. Postoperative lesions were sent to pathology. The operation was treated by particle impaction bone graft and plate internal fixation. RESULTS: All patients were followed up to resume normal life for 8 to 42 months with an average of 25 months. The function assessment referenced to the bone and soft tissue tumor association (MSTS). At the end of the last examination, the positive and lateral X-ray films of the femur showed no low density shadow in the margin of bone graft and bone graft, and the bone healing in the bone graft area was good. No recurrence or metastasis was found in all patients, and no loosening or deformation of the internal fixator occurred. The hip function was well restored and no fracture or deformity progressed in all patients. CONCLUSIONS: The tumor recurrence in the proximal femur is related to curettage and bone grafting. After the curettage, the residual tumor cells were treated by chemical and physical methods. By this method, the disease can be cured for a long time, and it can reduce the recurrence and resume the function of the hip joint.
