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?
