How did you get on?

Looking at getting the Securos PowerX Crimper and PowerX crimps, but continue to use the VI double-swaged on nylon leader line. Is that OK?

And discontinued. Tried to order a pair today.

Have ordered the securos crimper, nylon , crimps and a tensioner. They have already e mailed an instruction sheet. Seem very efficient and have UK rep so will see how we get on.

The compound action crimpers are indeed easier to use but I have had two slippage failures since beginning to use them The slippage occurred when using 80lb line in the 12 mm crimp (this crimp is also used for 100lb line which is probably more secure as there is less space around the line onto which to squeeze) Gratefully the 2nd incident occured while testing the joint post-operatively so I was able to open up immediately and replace with the larger line

Thank you Malcolm will check out their website. Its a technique we use with great success (until the last 3!!)

The company that originally developed the Crimp-Nylon system was Securos in the US. (Now owned by the same company that owns Centaur) Veterinary Instrumentation was one of a number of "me-too" companies that copied the idea. Unfortunately, they did so without paying attention to the significant amount of technical research that went into the original. (Declaration of interest - the developmental work was done by a good friend of mine, Karl Kraus)

The problems comes from both under and over tightening and yet more problems come when the crimp is manufactured from harder (but cheaper)stainless steel. Under tightening allows the nylon to slip through and it is really easy to under-sqeeze the cheaper hard crimps. Over-sqeezing damages the nylon significantly reducing its breaking strain. The Securos system featured appropriately soft and exactly sized crimps plus a dedicated crimping tool that squeezed enough but prevented damage to the nylon. The Securos system only ever uses a single crimp - the use of multiple crimps is evidence that the first crimp isn't working properly.

Fabello-tibial suture is, in my opinion, the best non-osteotomy CCL surgery but it is technically sensitive (many surgeons place the tibial hole far too distally). There used to be some good videos on the Securos web site but I haven't checked recently.

We've been using them for years without problem putting 3 crimps in , the only change has been in who is using pliers when we've been busy. I do think you need strong hands to close them properly

I don't know about other crimping sets, but I've never had a crimp failure. I think the key is once you've got the desired tension on your nylon, you add another couple of crimps using the pliers. You need to be fairly firm but not particularly strong to do them. There's a pretty good video of the technique I believe on the Vet Instrumentation website.
