1选材 取一段长约40cm的胸段脊柱标本,保留肋骨长约5cm,最好带3～4个腰椎.2 制作方法 修洁前纵、棘上、棘间、横突间、肋头辐状和肋横突外侧韧带.在下部腰椎矢状方向除去一个半椎体,以显露椎间盘矢状断面结构.然后上行一个椎体,从椎弓根处断离,去掉两个椎体,游离前纵韧带,保持该韧带的连续完整性,去除脊髓,显示黄韧带及水平位的椎间盘结构.再间隔一个椎体,从后部先游离棘上韧带,同样保持韧带连续完整性,然后除去二块椎板和棘突,显露椎管,去除脊髓及硬脊膜,暴露修理后纵韧带.3 讨论 以往椎间连接标本制作,大部分是将脊椎分成几段,各显示它的结构,形态教学效果不佳,整体感差,学
A material selection of a length of about 40cm of the thoracic spine specimens, keep the rib length of about 5cm, preferably with 3 to 4 lumbar spine.2 methods of repair before the longitudinal, spine, spine, transverse process, And transverse rib lateral ligaments in the lower lumbar sagittal direction to remove a hemivertebra to reveal the disc sagittal section structure and then up a vertebral body, from the pedicle at the fracture, remove the two vertebral bodies, free anterior longitudinal Ligament, to maintain the continuity of the ligament integrity, removal of the spinal cord, showing the ligamentum flavum and level of the disc structure.An interval and then a vertebral body, from the back of the first free spine ligament, the same ligament to maintain the continuity of integrity, and then remove the two vertebral Plate and spinous process, revealing the spinal canal, spinal cord and spinal dura removed, exposed repair of the longitudinal ligament.3 Discussion Past intervertebral connection specimens, most of the spine is divided into several sections, each showing its structure, morphology, teaching effect is not Good, poor overall sense, learning
