This paper summarized professor WEI Guikang′s manipulation and medication experience in treating early and mid-stage avascular necrosis of the femoral head. As avascular necrosis of the femoral head is complex and gradually progressed

it is necessary to consider the patient′s syndromes and pathological process in clinical practice

follow the principle of "obeying physiological characteristics

and reversing pathological changes"

take "unblocked transmission" of the normal function as the core

combine manipulation therapy with orally and externally administered herbal medicine

treat both the interior and exterior

and lay emphasis on both sinews and bones. Manipulation is mainly based on the triple therapy of "tendons-regulating

bone-setting

and symptomatic intervention". Syndrome differentiation and staged prescription of oral herbal medicine are recommended; at early stage when damp-heat syndrome is commonly seen

it is better to clear heat and dispel dampness

invigorate blood and unblock the channels; at middle stage when binding of phlegm and stasis is the major syndrome

and is accompanied by depletion of liver-kidney and failure of nourishing sinew-bone due to chronic and long illness

it is advised to dissolve phlegm and dispel stasis

supplement and boost the liver and kidney. Simultaneously

herbal medicine which can unblock the channels and quicken the collaterals

invigorate blood and relieve pain are suggested to be dococted and externally applied.
