Avascular necrosis of hip- New biological treatment options
A novel form of treatment is now available in India for patients with early stage avascular necrosis of the hip. This treatment is based on regenerative medicine.
Avascular necrosis of the hip is a condition of unknown origin affecting many young and middle aged patients. Steroid intake, alcoholism, Sickle cell diseas, hypertension, decompression sickness are some known causes. Moderate to severe disease is treated by hip resurfacing whereas core decompression is offered to the first stage of the disease. Grade II A disease is an intermediary stage between the two extremes and has no definite treatment options. There is controversy on the appropriate treatment. Hip replacement is perhaps too drastic an operation for this early stage of the disease. Core decompression has limited success rate. Left to progress it leads to deterioration and hip arthritis.
For this stage, a biolgoical option is now available. This is based on the potential of stem cells to heal the avascular bone. Stem cells are drawn from the patient and cultured in the lab. A few weeks later, they are injected back into the affected portion of the femoral head along with a core decompression. In a core decompression the surgeon will drill a tunnel in the hip bone leading into the affected area. The regenerative bone cells are injected into the affected area. The bone forming cells called Osteoblasts synthesize new bone in the dead area. This leads to healing and hence a biological cure. The technique is called Ossron
This process is avaiable in India for a reasonable cost.
