Ozone needle injection therapy, which uses an ozone needle with a diameter of only 0.3mm to puncture into the joint cavity of the disc and local tissues, is used to treat joint diseases without damaging the surrounding tissues, using overlapping therapy with intradiscal injections and intra-discal decompression and intradiscal drug injections. Because ozone can treat diseases such as arthritis and femoral head necrosis, the doctor gives appropriate sodium hyaluronate into the joint cavity to increase its biological function of lubrication and resistance to the action of mechanical forces, in conjunction with simultaneous drug injections, as appropriate to the patient’s condition.
