PIP Joint Arthrodesis With AlloSync™ Bone Dart

In this technique video, we're going to demonstrate the Arthrex AlloSync bone dart for the use of Hammertoe correction. So each each AlloSync allograft bone dart will come with an associated kit. The kit will contain the following items. You'll have a K-wires to help guide the drilling. You'll also have drill bits, including a two, five, two, seven, and 3.0mm drill bit. Each of these will be marked to to the necessary length to ensure that you drill to the appropriate depth. We'll also have a profile drill present to allow for additional opening reaming as necessary to help guide the implant in. In this surgical technique video, we will show a dorsal incision a dorsal longitudinal incision centered on the joint. So we'll go ahead and make the incision dorsally centered on the proximal interphalangeal joint. Now we can see we have our joint surfaces exposed. And we're next going to use our micro sagittal saw in order to remove the proximal joint surface as well as the distal joint surface. So we'll resect just proximally to the articular surface. And then we'll make a corresponding cut on the base of the middle phalanx removing that articular surface. This can be done with the saw or can be done with a ranger. So with the articular surfaces resected we can then go ahead and plan for the drill holes. We'll use our guidewire in our kit. We'll go ahead and put it down the center center of our proximal phalanx first, and we can confirm the placement of the guidewire on fluoroscopy. We can see here that we're down the center of the pipe here. So once we're satisfied with the positioning of the guidewire, then we'll go ahead and drill. Depending on the size of the bone and quality of the bone, you can start with either a 2.7mm drill bit or a three millimeter drill bit. In this case, we're going to start with a three millimeters drill bit. As we can see here the drill bit will be marked to 14mm. You want to be careful not to pass a point in this case because the proximal portion of the impact that you want to insert matches that 14mm. If you drill too deep, the implant may subside. And then we'll go ahead and place the guidewire into the middle phalanx next. All right. So we'll go again. Want to be in the center of the middle phalanx on both the AP and the dorsal plantar view here. Essentially, you want to be in the center of the middle phalanx. So in a similar fashion to the proximal phalanx, we are going to use either a 2.5 or a 2.7mm drill bit in order to create a path into the middle phalanx. The drill will also be marked at eight millimeters in order to make sure that you're at the appropriate depth. Again, care. You want to make sure that you don't over drill this or go too deep, because that may lead to displacement of the implant. So prior to final implantation of the implant we do include a profile drill, we'll typically recommend that if you need to help get the implant, especially in the proximal side, you can certainly use this to create a path. So now that we have the surfaces prepared, we're going to go ahead and proceed with inserting of the implant. Again the longer side goes into the proximal end. This is 14mm. The distal side is going to be eight millimeters. And you can see that the the barbs reverse in different directions to allow for capture within the bone. You want to take a coker or some other holding device that you feel comfortable with in order to get a good grip on the implant to give you some force to put it in. And so we'll proceed first with implantation into the proximal phalanx. You may have to regrip it in order to get it down to the appropriate depth there. And you can kind of see that's where the transition begins between the proximal and the distal portion. And then what we're going to do is now distract the joint and then bring the bring the middle phalanx up and over to capture that middle portion of the implant. We'll make sure there's no interposing soft tissue, and we'll put gentle axial load in order to complete the compression across the joint. And we can see there's nice apposition between the bones. And it's pretty compressed there. You can't really pull it apart unless you're going to put a tremendous amount of force here. And we'll check that fluoroscopic as well. So as we can see from the implant, it's well seated within the proximal phalanx as well as the distal phalanx. We have more threads within the proximal phalanx than we do the distal phalanx. There's good compression across the proximal interphalangeal joint from the standpoint of the surgical technique. There are no metal wires or anything that need to be cared for or nothing that needs to be removed. In addition, in any sort of revision situation that you may need, this implant can is something that will integrate within the bone and can be something that can be drilled through just like the normal surrounding bone.

Hammertoe Repair with RetroFusion™ Implant

The RetroFusion screw technology is commonly used for the repair of a hammer toe deformity. In this technique, your surgeon will make an incision over the top of the toe. Then your surgeon prepares both ends of the joint in order to allow for proper fusion. Next, a guidewire is used to mark the center point of each bone. A hand-drill is used to prepare the bones for the RetroFusion screw. The second drill bit is left in place, and the back end of the drill bit will be used later to engage the screw, similar to a screwdriver. The RetroFusion screw is turned clockwise until the threads are flush with the bone. Next, your surgeon will hold the toe straight and the screw driver is engaged into the screw. The screw is then turned counterclockwise until two thirds of the screw threads are inside of the bone. Lastly, the screw is then turned clockwise until both bones are secured in place. The driver is then removed and the incision is closed, completing the procedure.

RetroFusion™ implant is uniquely designed for PIP arthrodesis which provides excellent compression and strength across the joint. The implant’s proximal and distal threads are arranged in opposite directions which pulls the joint together for maximum compression of the PIP joint. The technique and instrumentation allows for insertion of the implant without having to leave it across the DIP joint.

RetroFusion™ Implant for PIP Joint Arthrodesis

RetroFusion™ Screw for PIP Joint

In this case, you can just incise right down to the bone. The collateral ligaments attach to the medial and lateral side of the distal end of the proximal phalanx. And if you slide your freer and then pull it open you can usually cut that. Now normally I will take just a bone biting Roger. And cut some of this. Cut the tip of that proximal phalanx. We'll take our saw back again. Okay, so then we've got those bony surfaces prepared, and we'll take a K-wires to drill, more or less a provisional hole. One proximally. And then the second. Going distally, you want to make sure you start right in the center. And what I'll do is have this come out the. The dorsum of the toe there. This specially designed drill has a drill bit on this end. And then from here down, it's fluted with seven, six sides. And so the the handle has a thumb screw which holds it. And the idea of this screw is we're going to we're going to use the, the drill to create a hole. And then on the other end we're going to, we're going to use the, the, the other tip of that drill to actually turn the screw. That allows you to not need a cannulation of the drill itself because you never really lose your position With a with a pilot hole from the K-wires. This can be done by hand, and I like to do it that way, because you get much better feel of the bone and how strong it is. And then the handle is placed over the opposite end, just till you start to feel the threads coming out that side. And then this is backed out. So it's just inside the joint, which allows you then to put the screw into the proximal phalanx. And that's a nice tight fit. The tip of the screwdriver has a little bit of a bevel right on the end, which makes it easier to to get into the end of the screw. So I'm backing this out turning it counterclockwise. And what you'll see happen is the the resected area of the joint will will separate, meaning that you've got it compressed into the middle phalanx a bit. And that's when you know you've got some tension on there. And as you come out, you'll begin to see the threads come out of the proximal end. And that's about that's about when you want to start turning it clockwise. I've just turned it another half turn, but now I'll start turning it clockwise. And you can see how the the two bones will compress together. Really a large amount of compression of that cross that site. There's sometimes just a little bit of a ridge of the bone on that. Middle phalanx you want to remove. So there it is. So that's quite a solid fusion. And you can see the IP join is free.

RetroFusion™ Screw is an implant with a dual threaded design used in proximal phalangeal joint arthrodesis. The RetroFusion implant is inserted between the proximal and middle phalanges, so the opposing threads on the screw will compress the joint.

The surgeon begins by making a linear incision over the hip joint. A saw is used to resect the head of the proximal phalanx. It is important to also resect the base of the middle phalanx down to subchondral bone, to ensure adequate engagement of the screw. A guidewire is used to manually find the central canal in the proximal and distal phalanx. Using the drill portion of the drill driver tool, the proximal phalanx is drilled to the first laser line. The drill driver tool is then drilled through the middle and distal phalanx and out the end of the tow, leaving the driver portion in the pip joint. The driver is left in the joint to later engage the screw. Using the extra driver in the kit. The screw is inserted into the proximal phalanx until the distal threads touch the bone. The driver end of the drill driver tool is then used to engage the head of the screw. While holding the middle phalanx steady. The screw is turned counterclockwise into the middle phalanx until two thirds of the distal threads are engaged. The surgeon then turns the screw clockwise to compress the joint. The opposing threads on the screw will cause the joint to come together for optimal compression. The driver is then removed and the incision is closed and a compressive dressing is applied.
