Key Points for Diagnosis:
According to the theory of traditional Chinese medicine, there are some patterns of syndrome that lead to avascular necrosis:
1. Stagnation of Qi and Blood due to Invasion of Wind, Cold, and Damp.
2. Joints Damaged due to Kidney and Liver Deficiency.
3. Hyperostosis due to Cold and Qi Stagnation
4. Numbness of Joints due to Stagnation of Qi and Blood.

                                                                                                                                              
In TCM, a disease or a symptom might be caused by one pathogenic factor, even two or three pathogenic factors. When diagnosing a disease or a symptom, TCM doctors must follow the principle of "Syndrome Dfferentiation", and then "Suit the Remedy to the Case". In order to gain a more definite and valuable diagnosis, it's important and necessary for the doctor to learn the detailed health information of the patient, including his/her disease duration, age, sex, height, weight, family history, urine, stool, diet, sleep, sweat, energy, mood (emotion), as well as the tongue conditions and the palm conditions, etc. If you would want our expert to create a TCM diagnosis, you're welcome to contact us.
