Hi, this is Peter Bock, and today I want to present our poster. This is a study about arthrodesis of the TMT2 and TMT2 joint. We did this arthrodesis of the lesser brace with a screw made out of bone graft, so this is something special. And we wanted to do this study because this is the first study on lisform arthrodesis done with this kind of screw made out of bone graft. The bone graft is harvested from the femur donors, and then the screw is fabricated. In this study, we had 23 patients with 25 feet. We had a follow-up time of about 15 months, with a minimum of 12 and a maximum of 33 months. We did a clinical evaluation with the AOA-FAS forefoot score, the foot function index, the foot and ankle outcome score, and the visual analog scale for pain. A radiological evaluation, where we had to have a look at the fusion rate, integration of the shark of the bone screw into the recipient bone. About our clinical results, we could see an improvement in all the clinical scores from pre- to post-operative, which was in all clinical scores and all the subscales clinically significant. The VIS score for pain improved to 4.1, and so in all the other scores, we could also see an improvement. Here you see again, sorry, I did a little mistake. Here again, you see all the scores pre- and post-operative from the visual analog score for pain from 7 to 2. FFI improved from 62 to 17, the FAOS for symptoms from 55 to 85, and the FAOS for pain from 30 to 87. In conclusion, we could see that all the screws made from bone donors was well-received by the patients, and at a maximum of 15 months, we could see that all screws were well-resorbed. So the good thing about this screw is you don't have to take it out, and in no case we saw any anapsis atrosis, so all of the joints fused properly. In conclusion, we think that we could demonstrate a significant improvement in all the clinical scores and also radiological scores with a screw made out of bone graft. Further studies will be needed for other foot surgeries, and this is the first one that we can present with this kind of screw. Thank you. Hello, model, you're on the move. Perfect, mouse. Everything is fine. I tried to document my poster, but I didn't succeed. I'll try something else. The poster for the American congress. Yes, that would be cool, yes. I'll try it again, but I'll see. If it doesn't work, it doesn't work. It's not a problem either. Take it easy. Exactly, honey, that's how it is. Yes, that's exactly how it is.
