Hip injection of sodium vitrate is usually selected for joint cavity injection, and the routine injection position is selected in the anterior and inferior part of the femoral rotor. Hip injection of sodium hyaluronate is aseptic operation, usually the patient takes the supine position, the puncture point of the skin range is routinely sterilized, after laying a sterile cavity towel, wearing sterile gloves from the anterior to the lower part of the femoral rotor into the needle, along the femoral neck of the medial side of the femur and the skin at an angle of 45 ° or so, and arrive at the articular cavity. After the puncture needle enters into the joint cavity, it is necessary to carry out the retraction operation firstly to clarify whether there is any joint effusion, and the injection of sodium hyaluronate can be carried out after the liquid is cleared by retraction. It is necessary to avoid damaging blood vessels and nerves during the puncture operation, and if necessary, positioning under the C-arm can be carried out. Hip joint injection of sodium vitrate is a kind of local closed treatment method, which is a kind of treatment method to inject different doses and different concentrations of the drug into the tissue, use its local drug action to reduce the local lesion irritation and improve the local nutrition, so as to promote the healing of the disease.
