A 14-year-old girl with a femur fracture can be treated with medication and surgery. 1. Medication: non-steroidal anti-inflammatory drugs, such as aspirin and diclofenac, can reduce inflammation at the fracture site and relieve fracture pain. Anticoagulants, such as low molecular heparin, can prevent thrombosis and avoid the occurrence of pulmonary embolism. There are some differences between individuals, the above drugs should be used under the guidance of the doctor. 2. Surgical treatment: Cut-and-replace internal fixation can restore the alignment of the fracture, and at the same time, fixation of the fracture with a steel plate can promote the healing of the fracture. Artificial joint replacement is suitable for patients with partial femoral neck fracture or intertrochanteric fracture. If you are diagnosed with femur fracture, it is recommended to go to the hospital in time and choose the appropriate method of treatment under the guidance of the doctor.
