As we all know, there are various treatments for femoral head necrosis, such as open femoral head drilling and decompression, artificial femoral head replacement, the application of traditional Chinese medicine, and the more modern interventional therapy. For patients with early onset of osteonecrosis or younger patients, the combination of interventional therapy and Chinese medicine is a proven method that can significantly alleviate the condition, prevent further progression, and help cure the disease. Interventional therapy is the use of superior arterial cannulation technology to inject drugs directly into the arterial vessels of the corresponding areas through catheters, causing the blood vessels to dilate, stagnation to disperse, thrombus to dissolve, blood flow to accelerate, and improve blood flow to the femoral head. Principle: The main reason for femoral head necrosis is the ischemic necrosis caused by various causes of blood circulation disorders in the femoral head. Interventional therapy is based on the pathological characteristics of femoral head necrosis, and its principle is to use catheters to directly inject large doses of thrombolytic and vasodilator drugs into the blood supply arteries of the femoral head, which can maintain a high concentration of local drugs for a longer period of time, causing vasodilation, stasis dispersion, thrombus dissolution, accelerated blood flow, increased blood supply, enhanced vascular nutrition of the collateral circulation, and promote the removal of metabolites, so that necrosis Bone is resorbed, new bone is created, and the femoral head is repaired.
