Accurate reduction and maintenance of the stability with correct implant positioning is critical for surgical treatment of tibial plateau fractures. Our technique includes an arthroscopic reduction and fixation of Schatzker type III tibial plateau fractures with a bulls-eye screw placement without fluoroscopy control. With the arthroscopic guidance, an anterior cruciate ligament drill guide is placed and a K-wire sent to the midpoint of the depressed fragment through the guide at a 40° angle to the coronal axis of the tibia. A tunnel is created with the drill over the K-wire. The depressed fragment is further augmented with gentle impacts over the K-wire. After arthroscopic reduction control, an appropriate-sized iliac graft is pushed until it is below the depressed fragment. The targeting device is adjusted at 130° so that it is parallel to the joint line and a K-wire sent through the device so that it would pass just below the graft. The graft is then supported with cannulated screws sent over the K-wire. This technique provides an arthroscopic reduction of the chondral surface and precise placement of the rafting screws without fluoroscopy.
准确复位并通过正确的植入物定位维持稳定性对于胫骨平台骨折的手术治疗至关重要。我们的技术包括在无透视控制的情况下,通过靶心螺钉置入对Schatzker III型胫骨平台骨折进行关节镜下复位和固定。在关节镜引导下,放置前交叉韧带钻孔导向器,并通过导向器以与胫骨冠状轴成40°角的方向将一根克氏针送至塌陷骨折块的中点。用钻头沿克氏针钻出隧道。通过对克氏针施加轻柔冲击进一步抬高塌陷骨折块。在关节镜下确认复位后,将合适大小的髂骨移植物推送至塌陷骨折块下方。将瞄准装置调整至130°,使其与关节线平行,并通过该装置送入一根克氏针,使其刚好从移植物下方穿过。然后用空心螺钉沿克氏针置入以支撑移植物。该技术可在无透视的情况下对软骨表面进行关节镜下复位,并精确置入支撑螺钉。
