Mao Yuanqing, Department of Orthopedics, Shanghai Ninth People’s Hospital: Femoral neck fracture is a more serious type and has been surgically repositioned for internal fixation. However, it is impossible to answer whether necrosis will occur in the femoral head because it is affected by many factors and there is no way to predict it in advance. What you need to do now is: 1. avoid weight-bearing on the affected limb; 2. regular outpatient follow-up radiographs (1 month, 3 months, 6 months after surgery), depending on the specific circumstances of each case; 3. if the injured side of the hip joint becomes painful and uncomfortable later, go to the hospital immediately to rule out necrosis; 4. if necrosis is suspected and the material of your internal fixation screw allows, MRI examination can be performed If necrosis is suspected and the material of your internal fixation screw allows, MRI examination can be performed. Patient: Thank you, Dr. Mao. Mao Yuanqing, Department of Orthopedics, Shanghai Ninth People’s Hospital: You are welcome, feel free to contact me if you have any questions Patient: Dr. Mao; Hello, I will check regularly, thank you for telling me. Can you treat femoral head necrosis if it is found? Mao Yuanqing, Department of Orthopedics, Shanghai Ninth People’s Hospital: Of course, it can be treated. The specific treatment plan depends on the situation of necrosis: In the early stage, extracorporeal shock wave therapy can be used, which is non-invasive and effective, and we have treated hundreds of patients. If necrosis develops, methods such as medullary decompression can be used. For advanced necrosis, surface replacement and total hip replacement can be used. Patient: Please ask Dr. Mao; I have been operated for one month, but I am still bedridden, can I walk with crutches? Mao Yuanqing, Department of Orthopedics, Shanghai Ninth People’s Hospital: You can go down on crutches, but you can’t put weight on the side where you did the surgery, not at all, you must pay attention.
