Read what spine surgeons are saying about the KG1
I tried the bone delivery tool twice this past week. It worked flawlessly. We’re trying to get it into the hospital through Gundy’s distributor company. I was able to use local autograft instead of DBX and the cost savings there should more than pay for the device. Let’s hope that strategy works. Good job conceiving the idea and getting it to market.
The Kleiner Bone Graft funnel assists my surgical cases and practice in several ways. Not only has it increased our documented fusion rates in patients from both a minimally invasive and open TLIF approach, but it greatly improves optimal bone graft delivery efficiency and safety. The funnel allows for stable and safe direct delivery of bone graft into the disc space without the need for nerve root and dural retraction. Eliminating repeated graft delivery near the dura and nerve elements through conventional means, this device greatly improves efficiency and safety for our patients. I have found that a combination of flowable graft extender in combination with ground autograft passes easily through the funnel without jamming or clogging. I have used this device safely and effectively in both conventional TLIF, OLIF and LLIF approaches.
I wanted to let you know what a beneficial impact the bi-portal bone graft tool has had on the way I perform my T-Lif and L-Lif operations. By using your device I was able to expedite bone graft insertion for these procedures and avoid the problems that I encountered with round, end-dispensing bone funnels including cannula tip visualization, jamming, injury to the bony end plates of the disk space and failure to distribute bone graft in the disk space. I found that I was able to introduce more scaffold and cells and still have room for my fusion cage. It has decreased my operating time, eliminated the frustration and challenge of interbody grafting and improved my early fusion results without using BMP. It works extremely well with any flowable graft extender and ground autograft. If there are any doctors who are interested in using it, please feel free to have them contact me so that I can share our experience with this device. Thank you for introducing this invaluable tool.
I have been using a posterior approach, minimally invasive - portal, for sacroiliac joint fusion for the past few years and I have been concerned that the joint is a lot larger than where I can place bone graft. With the Kleiner bone graft insertion tool I am able to place a significant amount of bone graft in the hard-to-reach spaces of the sacroiliac joint from my minimally invasive posterior approach. I have been very pleased with the amount of bone graft/putty and the directional placement of the graft with this tool. The distal tip marker also helps with positioning of the tool with fluoroscopy.
I learned of the Kleiner bone graft tool directly from Jeff Kleiner. He demonstrated a lot of passion in his invention, and I was immediately interested. TLIF procedures are at times tedious, and towards the end of the case, filling the disc space with graft was a repetitious process (I was using the Medtronic metal funnel), which necessitated placing and reinserting the device multiple times. Additionally, the graft is expelled at the end of the funnel, therefore not filling the disc space. The demonstration of the bone graft tool made immediate sense to me. I described it to my OR team as a “paperclip-like invention.” By this, I meant that this device is so simple, yet addresses many issues. I personally feel the device is brilliant and exactly what spine surgeons look for-simplicity and excellent functionality. The device allows me to precisely insert it into the disc space, with fluoroscopic confirmation, and then fill the disc space with 3-4x the volume I used to place. I place the device once, and therefore avoid the risk of a CSF leak or root injury with multiple placements of a funnel. When the device is removed, a channel is naturally formed for the implant! Brilliant! I have been using the device for several months; it took a while before my hospital got around to approving it - and am thrilled. Importantly, two of my colleagues have learned of the device and are enthusiastic about it as well. I whole-heartedly endorse this simple, brilliant design. Thanks for making my cases easier, faster, and safer, Jeff.
I just wanted to take a minute to let you know how pleased I am with the bone delivery device that you designed. As you [may know,] myself and a number of other orthopedic and neurosurgeons have begun to use it for our cases at Sky Ridge Medical Center. I have found that I have been able to get a great deal more graft material into the disc space in a much more quantifiable and rapid fashion. The delivery device has been very simple and easy to use and I have used it for both minimally invasive as well as in open applications. It has been particularly helpful for me in the minimally invasive fusions we do, greatly increasing the amount of bone graft material that I have been able to get into the interspace. I have also found it extremely helpful for our minimally invasive lateral approaches to the spine where due to the depth of the wound and the anatomy, it was difficult to get a good deal of bone graft into the interspace. The tool packs well and I have been able to use a variety of types of bone graft materials including autologous bone that we have morselized as well as other bone products such as Orthoblend and other DBM type materials. The tool is easy to use and is well-designed. The marking on it allows us to know exactly how deep to get the tool into the disc space and we have been able to distribute the bone graft more uniformly throughout the disc space than was previously the case. In the past, I have tried to use what the hospital provided as a bone funnel, but due to the aperture of delivery of the bone funnel we were not able to deliver the bone graft nearly as effectively. It would clog up and I would get frustrated and go back to packing the bone with forceps to place the graft then tamp it in with a bone tamp. Your tool is just so much faster. I just wanted to let you know that we are very pleased with it. I am very encouraged with our early fusion results. If there are any doctors who are interested in using it, please feel free to have them contact me so that I can share our experience with this devise. Again, I am a little upset that I did not think of it myself; it has been a wonderful addition to our practice.
