Observations on the pathological changes ofmicrocirculation in nail folds were made through the theory and the detection ofmicrocirculation to diagnose ischemic necrosis of femoral head at the early, mid or latestage. The detection was done for 15 746 cases of different diseases. Among them, 287cases(1.82%)of ischemic necrosis of femoral head(136 at early stage and 151 at the mid orlate stage) showed obvious changes in microcirculation. The changes included themorphologic maldistribution of blood vessel, blood exudation or stagnation, or increasesof venous plexus, dynamic state of blood flow rate showing the aggregation of the redblood cell at varying levels and slow flow, stagnation or even slight embolism of theblood. After the herbal treatment to promote blood circulation to remove blood stasis andto dredge the channels, the microcirculation was obviously improved in varying degrees.Meanwhile, the X-ray examination of ischemic necrosis of femoral head showed thesignificant improvement or disappearance on the focus of infection. This detecting methodcan be used to determined the non-obvious symptoms of ischemic necrosis of femoral head atthe early stage, the symptoms which can not be detected by the image examination.
