为了解薄的扁平骨垂直方向移动和骨愈合情况,以及骨牵引器和骨结合型植入体方法的有用性,作者对犬颅顶骨模型骨延长术进行实验性研究。 取约20kg杂种成犬9只。分为3组,每组3只。常规消毒麻醉后,于颅顶部矢状方向切开皮肤约5cm,剥离皮肤及骨膜,露出颅顶骨,沿矢状缝植入3枚直径3.75mm、长7mm纯钛植入体。经过10周后,2次手术连结旋钮,安装骨牵引器。采用裂钻,于中间植入体直径约30mm处,圆形切开颅顶骨全层。操作中注水,防止骨烫伤和脑硬膜损伤。充分止血后缝合创面。7d
In order to understand the vertical movement of thin flat bone and the healing of the bone, and the usefulness of the method of the bone tractor and bone-associated implant, we conducted an experimental study on the bone extension of the canine parietal bone model. Take about 20kg hybrid dogs 9. Divided into 3 groups of 3. Conventional disinfection of anesthesia, the skull in the direction of the top of the skull to cut open the skin about 5cm, skin and periosteum stripping, showing the parietal bone, implanted along the sagittal suture 3 diameter 3.75mm, 7mm long titanium implant. After 10 weeks, 2 surgical link knob, the installation of bone tractor. The use of split drill, the middle implant diameter of about 30mm, round incision cranial parietal full-thickness. Water in the operation to prevent bone scalds and brain dura injury. Suture the wound after hemostasis 7d
