has anyone here had the CornerLoc procedure done? My pain mgmt dr recommended it to me today and it sounds great but I can’t find any information about it or personal experiences. 



  • Agree, information is pretty impossible to find with the exception of the CornerLoc procedure itself. I think it is because the procedure is still relatively new. I believe, and may be wrong, but the procedure was just “approved” last year October? I hear initial results are great, that people are walking pain free right after the procedure. That said, I would like to see patients results 1 year, 5 years and 10 years out. I have a very lengthy fusion (T2-S1), C5-T1 facet joint degeneration (lordosis secondary to kyphosis), bilateral SI joint degeneration and bilateral greater trochanter bursitis. One of my surgeons said that SI fusion should be my absolute last resort. My spine pain specialist thinks CornerLoc is the best thing since sliced bread. My surgeons PA-C wonders how an SI joint fusion would ever heal correctly as those joints moves/shift, especially with the stress both sides would be under with my lengthy fusion and other issues. I am hoping that someone will see your question who has had the procedure and will enlighten us!

      I was told the si joint moves but very very minimal. In fact that is one of my problems too much movement.

  • I'm so interested in this, SI joint dysfunction is the worst! I will sure be watching to see if anyone here has had the procedure. I assume by the name that they don't fuse the whole joint. I know there are people on the site who have had a full fusion.

    I read several articles on this procedure. This is a summary of what I read. A group of medical "innovators" got together and came up with CornerLoc SI joint fusion system. After careful preparation of the SI joint, 2 CornerLoc grafts are placed orthogonally within the SI joint effectively creating immediate stability and an ideal environment for fusion.
    I also read where you have to see a doctor that is trained to do this procedure. As far as reviews, of course, you only hear the good.

    Do your research. Anything new that comes out is always labeled "the newest and greatest". 

    Hope this helps.

    pvidebeck [edit] Do you know if you need a fixation or fusion of the joint?  The screw based fixation/fusion systems like SI Lok and Zyga also provide immediate joint stabilization and you can bear weight immediately as well (assuming you're strong enough to do so).  There's also a new screw-based implant out there (I can't think of the name of it right now) that as it's screwed in, automatically decorticates the area it's passing through and creates it's own bone graft material, eliminating the need to separately harvest and place bone graft material in the joint (assuming you're having a fusion). For fixation purposes (I had a bilateral SI joint fixation with Zyga screws), the screws are put in to provide immediately stabilization of the joint, but no bone graft material is packed into the joint.  Another advantage of the screw-based implants is that in the event that they'd need to come out for any reason, they come out just about as easily as they went in.  I'm certainly not a biomedical engineer, but I wonder how difficult removal of the Cornerloc implants would be if they needed to come out for any reason.  I know that the triangular-shaped Ifuse implants are a nightmare to remove and basically have to be chiseled out (a lot of doctors refuse to do the removal process).  I wonder if the Cornerloc implants would present a similar challenge since they're square/rectangular shaped and couldn't just be "unscrewed" like one of the cylindrical-shaped screw implants.

    I have an appointment Monday morning to discuss the CornerLoc SI fusion vs. radio frequency neurolysis procedures for my left SI (my right side isn’t too far behind, but I have other surgeries coming up that need to take precedence right now). The doctor/spine pain specialist I am seeing is currently the only one in my state that does the CornerLoc procedure. Should be an interesting conversation, he is very knowledgeable and thorough. I always take my husband with to take notes so I can focus on the conversation. The doctor’s scheduler did say it is very probable that my insurance might not agree to pay for either procedure, no matter what option I select, but they will still try for the approval.  

  • @TitaniumSpine did you ever have the CornerLoc procedure done?

  • I had Cornerloc done on my right side last December (Dec 2018), I am having the left side done Jan 2020.

    The procedure has helped me tremendously. Especially the action of sit to stand and stand to sit. It has taken away the majority of constant pain, it can definitely still get pretty cranky depending on my activity level, which I would like to say it pretty high. 

    The procedure itself was not very long 1 1/2 hr maybe and recovery was not horrible. I was up and walking right after surgery, I went home the same day. The pain was pretty intense for about 4-6 days and then it was like some one hit a light switch. Once the “procedure pain” calmed down the relief from the surgery was very apparent.

    The hard part for me was that I felt better but the recovery instructions still limited what I was allowed to do, I was very diligent about following the restrictions, although I had to be reminded that even though it was a non-invasive approach it was still a major surgery. 

    Things I didn’t know until after....there was a lot a bruising. It was fine an obviously finding a comfortable sleeping position was difficult. I found that keeping the incision area in the crack of my couch cushion was most comfortable. My surgery was video taped and those that watched said....uhh omg, I can completely understand the bruising! Lol I guess that’s why we are knocked out!

    All in all I am happy. I knew it would not be a cure all and I knew that I may eventually need the other side done, but I am very happy with the outcome and the relief it has given me. 

  • @pvidebeck sorry, haven’t been on this site in a while! I did not have the procedure yet. The doctor who was/is  going to do the procedure was working with my insurance but the procedure was ultimately not approved. My insurance said it is still too new so the procedure is considered experimental. One of my back surgeon’s PA-Cs said to just wait a year or two and try to get it approved again after some time passes and they have done more successful procedures. For now I am going to continue with physical therapy, heated pool therapy, massages, injections...and I am get more serious about taking off some weight this year to hopefully help relieve some of the pressure on those joints while I wait for insurance companies to catch up. It isn’t like my SI joints aren’t going to just keep degenerating, so I have to do some things in the interim to try and lessen the issues and pain/s. Might not help, but it can’t hurt to keep trying!

    Great to hear from you! I'm sorry you are still having to wait on surgery. I had water therapy at one point and loved it. It helped so much. I do not understand insurance companies as corner loc is not a new procedure. 

    Good luck and keep us posted,
