Purpose of the research: Avascular necrosis (AVN) is additionally referred to as osteonecrosis, bone necrosis, bone infarction, aseptic necrosis and ischemic necrosis. It is a condition in which the bone "dies" as a result of loss of blood supply to an area of bone tissue. In extreme cases, it may result in the collapse of a section of bone. Once the joint surface is involved, it may result to progressive arthritis. Avascular necrosis (AVN) can affect knee, shoulder, wrist, ankle, hands and feet. Among them the femoral head is the most common type of necrosis affecting the bones. In India, 16000 new cases of AVN are diagnosed every year. Management of AVN aims at the preservation of structure, function and relief from pain. Many surgical procedures such as drilling and insertion of bone grafts etc. are carried out to treat the condition but all these procedures are costly with the prognosis being poor. Signs and symptoms of Avascular necrosis are nearer to Asthivāha Srotoduṣṭi Vikāra (disorders of musculoskeletal origin) and can be considered with Asthimajjagat Vata (chronic stage). An effort has been made in the present study to evaluate the efficiency of Ayurvedic formulations in the conservative management of AVN of the femoral head. The changing life style of human being by means of dietetic and behavior pattern plays a major role in the manifestation of several disorders. The ages of 25 and 45, and is a chronic disabling condition often causing pain and deformity. The present study aims to assess and compare the effect of Virechana Karma and Basti Karma in the management of AVN of Femoral Head. Patients will be randomly grouped into Group A or Group B.  In Group A, Virechana karma followed by Ksheera Basti for 16 days. In Group B, Virechan karma followed by Matra Basti karma for 16 days. The research takes place over 30 days with 1 month follow up period in total for group A, and group B. It will be necessary for patients to admit in the hospital   in group A & group B. Duration: The research takes place over 30 days with 1 month follow up period in total for group A, and group B. It will be necessary for you to admit in the hospital for 18 days in group A & group B. Side Effects: As already mentioned, this drug has no known unwanted effect. It is possible that it may also cause some problems that we are not aware of. However, we will follow you closely and keep track of any unwanted effects. We may use some other medicines to decrease the symptoms of the side effects or we may stop the usage of drug. You will always be consulted before moving to the next step. Risks: By participating in this research, it is possible that you will be at greater risk than you would otherwise be.  For example, there is a risk that your disease will not be relieved and that the new medicine does not even work as the old one.  If the medicine is not yielding any positive effect on AVN in four weeks, we will offer you to choose other treatment options which may be modern, Ayurvedic or any other. Benefits: If you participate in this research, your participation will help us to resolve the research question.  There may not be any benefit for the society at this stage of the research, but future generations are likely to be benefited. Confidentiality: We will not be sharing the identity of those persons participating in the research. The information that we collect from this research project will be kept confidential. It will not be shared with or given to anyone except me and the DRC members.
