Hi Pat,
New questions appear more quickly then I thought. This one I do not know to what topic to post.
Stem cells therapy for AVN hip. Does anyone tried it before going for the operation? If it did not help, is it still possible to go for BHR?
Regards,
Vlad.
I can help with this as I have done some good reserach in this area and am currently partaking in such a procedure by a well known Dr and BioChemistry board chairman in the Ortho/Biomedical Engineering profession
Autologous SCT (Stem Cell transplant) Protocol is used primarily for STAGE I-STAGE II AVN Patient. There are mainly 4 Steinberg stages (some claim 5) as I am sure some of you AVN Patients know. The reason why only stage I or II is considered is because stem cells take many many months to start filling in the holes in the bone resulting from bone resorption (Osteclastic activity). 6-24 months is the timeline. If you are stage III then you in all probability will not have that much time before Joint collapse. In other words, by STAGE III, The disease IS advancing faster than stem cell growth can repair. Results have been poor with such later stages
The procedure, known as a BMAC, (Bone Marrow Aspirate Concentrate) is simple and is used during a CD (Core decompression) The Dr withdraws Bone marow from the Iliac Crest, Spins it down for a more concentrated form (because stem cells exist in small numbers throughout the body and a small number will be in the initial draw), then injects the marrow approx 30 minutes later into the Femural head during the decompression process
I believe The hope is that the stem cells can "grow under any remaining nourishment" and initiate Osteogenesis on top of the necrotic areas while also (I believe) re-establishing a new vascular system (which is really the main problem here)
The procedure is scientifically supported by the works of Dr Hernigou and Dr Gandji. Their results, based on a 24 month timeline period from the day of implantation, were published in the IJO (Indian Journal of Orthopaedics), I believe in 2006 or '07.
There is very strict protocol that must be adhered to based on the works of the 2 Dr's above. Please note, this is not the same protocol where the stem cells are withdrawn from the patient, havested for a week's growth for higher stem cell numbers, and then reimplanted back into the patient's body a week to 10 days later ( A certain Dr on the west coast does this) That procedure is not FDA approved. I know that Contamination is one of the FDA's concerns with that procedure
I am 3 months and 3 weeks out from my BMAC. I had it done in Late aug and there was another AVN patient in my room who had it done 2 hours prior to me. He was at stage II. Nothing is expected for 6 months is what I am told. Unfortunately, I have detected a slight deterioration in the past month. Nothing significant but it is noticeable (More pressure in the pubic bone area when I sit).
In 1 year an MRI is done to detect any new vascularization and any favorable bone marrow changes. A 2cnd MRI is done a year later. I will evaluate the MRI 9 months from now. If there is evidence of new bone growth or vascularization, then I will wait another year regardless of how I feel.
If there is no evidence of revascularization or bone growth and I continue to decline even a little bit, then i may begin making plans to have Dr Bose do a BMHR. He normally prefers AVN to reach its end stage where he then does a BHR (see his AVN Protocol on his site). However, for early stage AVN Patients who cant tolerate the pain, he does offer a mid resection option. I will choose the BMHR, not because I am impatient, but because I simply will not choose to experience the pain that will accompany later stages in order just to get a BHR. That will put me out of work and I cant afford that. Plus, it will mean more QOL (Quality of Life) loss (probably 2-3 years) and we all have only a certain amount of time to spend on this planet. At 47, I wont chose to experience the next AVN stage to fill some of that remaining time on earth.
With the nature of AVN's Inevitable Joint Collapsed outcome and nothing else medically available to reverse AVN, I am sure Dr Bose can understand my reasoning
I hope my feedback has helped
