bone matrix mixed with your own bone?

My son had 5 opinions for surgery (L4-L5/L5-S1) for his spondylolisthesis. Three said he would need to have a bone harvest from his hip. One said he would use the bone he was removing from his spine and mix it with bone matrix instead of harvesting the bone. One said he would do an anterior/posterior with BMP, but the other doctors said they wouldn't recommend that since he's very young and there is a slight chance of a nerve being damaged which would cause him to be unable to have children. They recommend a posterior approach.

He is so conflicted. He doesn't want the anterior posterior approach, so that's out. He wants to go to the surgeon who uses the bone matrix because it would eliminate the bone harvest, but he's nervous that it won't fuse. These are all top doctors BTW.

Has anyone had surgery using bone matrix? Thank you for any insight you can give me into this..

Re: bone matrix mixed with your own bone?

I'm pretty sure that the bone matrix is the same as the BMP. Surgeons have had a lot of success with the BMP and fusion, with fairly high fusion rates. I don't think your son needs to worry much about that part of it as long as he follows his doc's instructions post-op. I'm 24, and I had my fusion done with a mixture of donor bone and BMP. It's too early to tell about fusion (it's only been two weeks), but so far I'm very pleased. How old is your son? Let me know if I can help you in any way!

Re: bone matrix mixed with your own bone?

Well, to be perfectly honest the first 72 hours aren't wonderful. You are really in a lot of pain at the beginning. For me it was a different pain though. All of my pre-surgery pain was gone, and was replaced by the pain from all the work my surgeon did. I don't remember a whole lot because of all the narcotics I was on, but I'll do my best to help you out!

I was in the hospital for four days. I woke up on my back, without my brace. I was hooked up to a PCA pump with morphine (thank goodness for that!) and I had a catheter, as well as an IV with antibiotics and something else (fluids I think). I remember using the pump a lot, but sometimes it just didn't control the pain and then the nurse would give me something else for breakthrough. I was sick to my stomach a lot during my hospital stay, because of all the narcotics. They got me up the first morning after surgery, and that was not a lot of fun. I couldn't believe they were making me get up less than 12 hours after surgery (I didn't get out of recovery until around 11:30 PM because my surgery lasted almost 7 hours). I had my brace on when I was up, and I did manage to walk a little bit using a walker. I'm not going to lie, it hurt, but now I'm glad they made me do it. After that, I was up a little bit more each day. I was only on the PCA pump for 2 days (maybe 3- not sure), and then they switched me to only oral meds. I started using the bathroom myself after the second day, so that's when they took the catheter out. By the time I went home (on day 4) I was able to dress myself, climb stairs, and walk fairly well with the walker. I think my hospital stay was pretty short for a fusion, but I was really motivated to get out of there.

I hope this helped. Good luck with your surgery! Please keep us posted when you can!

Re: bone matrix mixed with your own bone?

I had cadaver bone for my anterior/posterior two level fusion. I am one month post op and doing well. I have my first follow up with xray tomorrow (third time seeing my dr).

Re: bone matrix mixed with your own bone?

It's awfully scientific but it looks like to me that BMP is in bone matrix. BMP is more expensive because it has to be extracted and/or made in a lab, and it needs a carrier. If you google 'bone matrix and bmp' you'll be as confused as I am.

I was fused posterior from L3-S1 with BMP, mixed with shavings from my laminectomy and donor bone, on sponges that were laid on either side of my spine. The BMP fuses faster than your own or doner bone. I think the bone matrix is used in a paste form and the BMP is in a liquid solution that is applied to sponges. My procedure was not approved by the FDA so I don't know what your options would be.
