Update on Stabylx revision surgeries. See my previous comments for the history. I chose to have the Right Stabylx implant removed and revised after experiencing a very positive outcome with the Left side revision with complete pain relief. Now post op about 3 1/2 months for the Left thumb revision (Left Stabylx implant removal w/ Trapeziectomy and liigament reconstruction, tendon interposition [LRTI] ) and couldn’t be happier with the outcome. The right thumb was revised on 12/15/21 with the same procedure as the left. Now post op day #20. Of note, the Stabylx implant is designed to “grow into the bone” and it did just that. This painful Stabylx implant was in place for over year and required a small osteotomy(cutting the bone) in order to remove the implant. This of course resulted in more post op pain but that has mostly subsided. Range of motion at this date is good. Right gentle wrist flexion, extension is pain free. Gentle distal, middle and proximal thumb joint flexion is excellent with minimal discomfort. The decision to revise was based on the ongoing discomfort from the indwelling Stabylx implants. An interesting finding from both surgeries was that on both of my thumbs, it was discovered that the the Stabylx implant flange had caused the FCR ( flexor carpi radialis ) tendons to rupture. Apparently the flange on the Stabylx implant caused these tendons to fray, in my case, at the attachment point on the thumb, then ultimately to rupture. Very painful and, in my opinion, ultimately the root cause for the pain and the need for the revisions. The FCR tendon is the usual donor for the “anchovy” construction but their ruptures negated their use and required in their absence that the APL tendon be utilized. I will reiterate that these Stabylx implants were ultimately a complete failure in the ability to relieve the CMC arthritis pain, and in my case actually caused more pain and damage. I definitely do not recommend their use. From my personal experiences and in my opinion it should not even be on the market or offered to patients. The failure rate is too high. It’s my opinion that the documented flange design flaw in the Stabylx implant precludes its use for this surgery at this time. I do, however, highly recommend the historically successful Trapeziectomy w/ Arthrex mini tightrope as a reliable procedure (96% success rate) for the relief of this very painful arthritis of the thumb. I hope this thread is helpful to those who are faced with this surgical decision.
