The etiology of orthopedic diseases is mostly related to trauma, and its pathogenesis is mostly blood stasis and blood deficiency. The etiology and pathogenesis of the two diseases are different, so it is difficult to combine them in theory. But in the treatment of orthopedic diseases, there are indeed classic prescriptions, and the effect is good. However, clinical prescriptions are mainly selected according to the main syndromes. For patients with deficiency-cold type of low back and leg pain, the clinical manifestations are mainly chills and cold limbs, and the symptoms get worse after catching cold, so it is considered that feeling cold and dampness will cause pain. Therefore, the treatment should be based on expelling wind, dispelling cold and removing dampness. Although the pathogenesis of diseases in orthopedics and traumatology is not exactly the same as the classic prescription and pulse syndrome, this classic prescription can be used if the main symptoms are the same and the pathogenesis is roughly the same.

Second, the location of circulation.

Some clinical diseases, such as stiff neck, cervical spondylosis, etc., can be treated with pueraria decoction as long as their parts are fixed, and the effect is excellent. Another example is peripheral neuritis of limbs. If the limbs are not warm, most of them are lack of qi and blood, and the tendons are out of temperature. The affected hands and feet have cold symptoms, which can be modified by Danggui Sini Decoction.

Third, according to the meridians

Clinically, many orthopedic diseases occur along meridians. Therefore, we should focus on the location of the meridians where the lesions are located. If the classic prescription is selected for treatment, if the syndrome differentiation can be accurate, the effect can generally be obvious. For example, according to the principle that the meridian of the sun "starts from the inner canthus of the eye" and reaches the waist, Huangqi Guizhi Wuwu Decoction is used to treat patients with kidney deficiency-type lumbago and leg pain, mainly based on its exogenous wind-cold, dampness blocking meridians and internal injury to kidney-yang, while Huangqi Yiqi Wenyang Guizhi Decoction, plus products for promoting blood circulation, removing blood stasis, expelling wind and removing dampness, has remarkable clinical effect.

The application of classical prescriptions should be based on syndrome differentiation, not limited to the indications of the original prescriptions, nor to the statement that classical prescriptions cannot be added or subtracted. Whether it is used alone or in combination, it can get good results with the increase and decrease of symptoms, and it is difficult to cure arthralgia syndrome completely in a short time. Treatment should be based on a certain prescription, the Dafa is basically unchanged, and the auxiliary drugs should be added and subtracted with the symptoms. The treatment is based on syndrome differentiation and treatment of cold, heat and yin and yang, and the methods of removing blood stasis and resolving phlegm, dredging collaterals and strengthening the body resistance are adopted, which are unchanged and unchangeable.
