Shock wave therapy of the femoral head

Femoral head necrosis is a common disease in clinical practice. This disease is very harmful to people's bodies. Clinically, femoral head necrosis also has staged treatment. In the early stages of femoral head necrosis, the more common treatment methods also include shock wave therapy. Of course, the treatment effect also depends on people's physical condition. It is undeniable that the effect of shock wave therapy for femoral head necrosis is quite obvious.

1. For early-stage femoral head necrosis, the cure rate can reach over 65% using shock wave therapy. This is a welcome medical development considering that femoral head necrosis ultimately requires joint replacement. At the same time, the angiogenesis-promoting effect of shock waves is very important for fracture healing, and can improve the vascular distribution and biological environment of the fracture site. Extracorporeal shock wave therapy has shown significant effects in the treatment of osteoarthritis and osteoporosis in the elderly.

2. Shock wave was originally a physical concept. It was first used in the medical field to treat urinary stones, namely "extracorporeal shock wave lithotripsy". The principle is to focus the extracorporeal shock wave on the stones and break them into mud and sand, which are then excreted from the body with urine to achieve the treatment purpose. This saves patients with stones from the pain of surgery and is a breakthrough in the treatment of urinary stones. Extracorporeal shock wave therapy is a non-invasive treatment that improves the regenerative capacity of tissues through mechanical stimulation. Based on this principle, foreign orthopedic surgeons have explored its use in the treatment of sports injuries and other diseases. Abroad, the clinical application of extracorporeal shock wave therapy has received widespread attention from multiple disciplines such as orthopedics, sports medicine, and pain medicine. It has now become an important method for treating clinical orthopedic diseases.

3. High-energy shock waves cause small bubbles in the medium to expand rapidly, leading to micro-injury, micro-fractures and hematoma formation in tissues, inducing vascularization, enhancing intramembranous ossification and accelerating cartilage ossification, reducing local inflammatory response and promoting disease healing; pressure waves can change ion channels, change the polarity of nerve membranes, and produce analgesic effects and relieve pain by inhibiting depolarization.
