摘　　要：BACKGROUND Osteosarcoma is one of the most common primary malignant bone tumors and is more common in adolescents.The femur is the most common site of osteosarcoma,and many patients require total femur replacement.We reviewed the relevant literature and case findings,summarized and analyzed this case in combination with relevant literature,and in doing so improved the understanding of the technology.CASE SUMMARY The case we report was a 15-year-old patient who was admitted to the hospital 15 days after the discovery of a right thigh mass.The diagnosis was osteosarcoma of the right femoral shaft.After completion of neoadjuvant chemotherapy and preoperative preparation,total right femoral resection+artificial total femoral replacement was performed.Then,chemotherapy was continued after surgery.The patient recovered well after treatment,and the function of the affected limb was good.No recurrence,metastasis,prosthesis loosening,dislocation,fracture or other complications were found during 18 years of follow-up.At present,the patient can still work and lives normally.The results of the medium-and longterm follow-up were satisfactory.CONCLUSION Artificial total femur replacement is a feasible limb salvage operation for patients with femoral malignant tumors,and the results of medium-and long-term follow-up are satisfactory.
