The first shock wave lithotripter (DornierHM3) was successfully developed in the 1980s in collaboration with German engineers and medical experts for the lithotripsy of renal ureteral stones (SWL), followed by different models of lithotripters for the lithotripsy of biliary tract and gallbladder stones. After the successful use of shock wave lithotripsy for urinary and hepatobiliary stones, high-energy shock wave technology was introduced into orthopedics, first for the treatment of delayed fracture healing and bone discontinuity, with clinical trials achieving bone healing. This success story led to a new concept – ESWT, Extracorporeal Shock Wave Therapy (ESWT). Because ESWT is a non-invasive treatment, it caught the attention of the European orthopedic community from the very beginning. German orthopedic surgeons use it to treat calcific tendonitis of the shoulder, tennis elbow, plantar fasciitis, and pseudarthrosis; American orthopedic surgeons use it to treat chronic heel pain syndrome (plantar fasciitis), with a single ESWT success rate of 76% and a repeat success rate of 81%. In October 2000, the U.S. FDA officially approved the Swiss HMT shock wave therapy machine for the treatment of heel pain syndrome. At present, the application of ESWT has been used for 10 kinds of orthopedic diseases in Western European countries, which has become a new therapy for the treatment of specific motor system diseases. at the beginning of the 21st century, the application of ESWT in Western European countries has been expanding and has been tested for the successful application of bone ischemic necrosis, especially femoral head ischemic necrosis, with great success, and this technology has become popular in Europe and America and other countries. In China, the development of shock wave lithotripter started formally in early 1983, and in 2003, the extracorporeal shock wave therapy machine was developed. China’s State Drug Administration (SDA) in August 2000 approved shock wave therapy for clinical treatment of orthopedic diseases [Registration No.: State Drug Administration Machinery (Test) No. 302156 2000], the U.S. Food and Drug Administration FDA has been approved in October 2000 by the clinical treatment of shock wave in plantar fasciitis, Taiwan Department of Health in April 2002 to review and approve shock wave in the clinical treatment of orthopedics. The State Drug Administration (SDA) of China approved the Swiss HMT shockwave therapy machine for the clinical treatment of orthopedic epicondylitis of the humerus, bone discontinuity, calcific tendonitis of the shoulder and plantar fasciitis in July 2002 [Registration No.: State Drug Administration (Jin) 2002 No. 3210888]: it is also effective in Achilles tendonitis and ischemic necrosis of the femoral head. Others, such as the Korean KFDA, were also approved one after another in 2002. Shock wave is a process of energy and momentum transfer, which is divided into mechanical and electromagnetic waves. The therapeutic effect is achieved by the sudden release of shock wave energy to produce waves that act on local tissues. This kind of clinical treatment purpose based on the principles of physics, geometry and biology has a creative scientific nature. Clinical applications confirm that shock wave technology reflects its scientific nature through the following aspects. 1, the application of shock wave properties: shock wave characteristics of some of the necessary conditions for clinical medicine. One of them is high energy. Shock wave lithotripsy technology used to focus the shock wave has a pressure of 102-103N.Kg/cm2, which provides sufficient energy to destroy brittle stones; secondly, its penetrating power, this feature ensures that the shock wave propagation in the body, will not significantly attenuate, and does not cause damage to human tissue. 2, focusing technology: focusing technology is based on the focusing characteristics of shock waves, the use of physics and geometry design of innovative technology. Unfocused shock wave is scattered, after the focus of the shock wave is focused. Focused shock wave action after the tissue target to produce non-invasive treatment purposes, thereby reducing the skin pain and tissue damage degree. 3, the choice of propagation medium: shock wave generation, the need for a medium to penetrate the energy through the skin layer by layer tissue to reach the treatment target. Due to the physical properties of water and human tissue is similar, in physics, the human soft tissue can be considered as physiological saline. The shock wave propagates between biological soft tissues and water as if it were propagating in a homogeneous field, and is able to enter the human body effectively. Therefore, SWL and ESWT, water is used as the best choice of shock wave propagation medium, the treatment to avoid the shock wave into the gas-containing organs and damage occurs. 4, the choice of destruction: When the shock wave in the treatment of internal stones and urinary stones, is done in two ways, one is the large energy type quickly crushed; second is the small energy type slowly crushed. Under the same conditions of total energy, large energy has a fast crushing effect, but also cause tissue damage; and small energy type under the continuous action of pulse, can make the stone gradually crack, disintegration, broken, and finally into fine sand, is small tissue damage. Therefore, the advantages and disadvantages of the choice and benefit. 5, the use of biological effects: shock wave into the body, will naturally produce positive and negative biological effects. eswt is the use of shock wave various biological effects to treat sports diseases. Specifically reflected as: stress effect – the action on bone tissue to cause the formation of hemorrhage and hematoma, is obsolete fracture end of the bonding effect of osteoblasts and mucin, activation of osteoblasts, bone healing. At the same time, the nerve stimulation effect at the cellular level and the degradation of calcium deposits are used for the treatment of osteophytes, frozen shoulder, tennis elbow, early fusion of joints, myosynovial adhesions, sclerotic bone lesions, etc. Cavitation effect – eliminates bone friction to produce pain, stimulates embolized blood vessels, accelerates blood flow, improves blood circulation, activates osteoblasts, accelerates the decomposition of dead bone and necrotic tissue, promotes vascular regeneration and bone tissue regeneration, used for the treatment of various osteonecrosis, joint cavity effusion, bone discontinuity, etc.
