Radiofrequency ablation, in general, is not effective in the treatment of femoral head necrosis. Radiofrequency ablation refers to the use of thermal energy generated by radiofrequency current at the tip of the catheter or needle under image guidance to accurately ablate hyperplastic tissues or abnormal foci, so as to restore the function of the corresponding tissues and organs partially or completely, and to improve the patient’s living condition. It is commonly used in the treatment of cardiac arrhythmia, cervical spondylosis, thyroid nodules, liver and gallbladder tumors, and diseases related to high sympathetic excitation. The treatment goal of femoral head necrosis is to prevent femoral head collapse and preserve the biological hip joint as long as possible. Commonly used treatments include non-surgical and surgical treatments, but femoral head necrosis progresses faster and non-surgical treatments tend to be ineffective, and most of the patients will face surgical treatments. In conclusion, radiofrequency ablation mainly ablates the abnormal tissue, while the treatment of the femoral head is mainly to preserve the hip joint as much as possible, therefore, radiofrequency ablation has no obvious effect on the treatment of necrosis of the femoral head.
