ContourLock™ DFO Plate With Patient-Specific Guide

Speaker  Hi everyone. My name is Aaron Critch from Rochester, Minnesota, and I'm very excited today to demonstrate on a sawbones, the Sy or patient specific instrumented distal femoral lateral opening wedge osteotomy. So walking through everything that you need. We have our validator. We have our custom patient guide. We have the patient's own model that's printed from their preoperative CT scan. We have four of our 3.2mm drill bits. We have our four pins that will hold the guide to the bone. Our BB tacks. We have our ContourLock distal femoral osteotomy plate, our saw blade. And then instead of having a whole caddy full of screws, we have all the screw lengths predetermined based on our preoperative plan. When you look at the validator. So this validator for this patient will be a nine millimeter opening wedge osteotomy. So this is the double check to make sure we have the precise amount of opening that we need. And this will hold our osteotomy open while we're applying our plate. One advantage before the case starts is you can take the patient's own anatomical guide and the patient specific or sci cutting guide and place it so you can feel exactly where it wants to fit on the bone. So you get a precise location every time with this sci cutting guide. Okay, so we're going to do our sci lateral opening wedge DFO. Speaker  So here we have the distal femur on the lateral side. And we're going to plan for a nine millimeter opening wedge for this patient. So here we have our sci cutting guide. And again we're going to get this in that correct place. And this guide we love about is it locks in very well. And you can see how it hugs both the posterior cortex. You can see how it hugs the anterior cortex. Then it goes right around the lateral epicondyle and this prominence here. So next we're going to place our BB tacks. So there's two proximal to distal. And this will help secure our guide before we place any of our hinge pins. So once our cutting guide is nice and secure we're first going to establish our two hinge pins. So we'll enter the lateral cortex. And these will be positive stop. And in our preoperative plan we would want these hinge pins to be about a finger breadth above the medial epicondyle. Now at this point as a surgeon, I could check with fluoroscopy to make sure that these hinge pins were exactly where I wanted them, and that our PSI cutting guide was exactly what our preoperative plan had dictated. Once we're happy with that and secure, then we're going to pre-drill our distal cancellous screws as well as our proximal 4.5mm screws. Speaker  So once we pre-drilled all our holes, now we're going to remove the upper portion of our guide. So we simply remove the two proximal BTB tacks. And then at this point we're going to make sure we dissociate the guides. So we're actually just going to use a small little rongeur. And these are easy breakaway tabs. So now we have our cutting guide distally secured. And we can take this proximal portion out. And that gives us plenty of room to do our osteotomy with the secure distal part of the guide in place. Okay. Our cutting guide is now all set up for osteotomy. Normally we'd have soft tissue retractors both on the front and the back during a real case. What's nice is we have our hinge pins completely protecting our contralateral cortex. So it makes for a very efficient osteotomy. So once our osteotomy is complete now we can remove our cutting guide. So we'll take out our two BB tacks. At this point you can see our osteotomy is springy. So again we're going to go back to our validator. So in this case we're going to do a nine millimeter opening. So we want to check with our validator that our orientation is correct. So you can see here there's an arrow up and that says proximal. So I know that's proximal for my validator. Speaker  So I'll get the jack opener in first. And I want to leave room in the back for our validator. So we're going to make sure this goes into our osteotomy. And then we can slowly open it over time. So we're just going to slowly use the jack opener. And then we're going to place our validator. So that looks great. So then at this point our jack opener can come out. And what's great about having these hinge pins in is now we have a very stable osteotomy. So you can see here our medial cortex completely stable. This is a great advantage of the PSI guide. So at this point we're ready to remove our hinge pins and place our plate. And we already have our pre-drilled holes. So this should be quite efficient for us. So at this point we have our nice stable osteotomy. We've got our validator in place. If we want to do some bone grafting we certainly could. It's wide open right now. And remember we pre-drilled for most of the holes in this plate. So when we place our ContourLock DFO, you can see how everything lines up well. So we're going to start with this anteriormost screw. And again these distal screws are six five and cancellous. And then our proximal screws will be 4.5mm bicortical. So I don't bring every screw all the way down. Speaker  What we'll do is we'll just make sure that they're all lined up in the plate before we do our final tightening. And then we'll leave our validator in place until we have a proximal screw lined up. So we're going to add our first 4.5mm bicortical proximal screw. So once we have our pre-drilled screws all in, we can remove our validator. And now we just have to drill for our last two screws. Again, the purpose of not having these two screws for this plan on the PSI guide was just so. The guide was lower profile and not as much soft tissue dissection. So we'll drill for our proximal screw. And this one is bicortical. And then our distal screw will be cancellous. So then we'll just place our final two screws in the construct. This is also a 4.5mm screw. So now you can see our completed construct. For our psi DFO osteotomy. We precisely open to nine millimetres in accordance with our preoperative plan for this patient. And a couple of things you'll notice is that you have a nice stable osteotomy. So that medial column is perfectly intact. So this one should heal very quickly for our patient. So again a very efficient and precise way to have an individualized psi DFO osteotomy for this patient.
