How human bone models support clinical diagnostic training

在教学楼的解剖实验室里，一套标注了神经根走向的 175 cm 全身骨骼模型正被住院医师围观。它不是单纯的装饰品，而是把解剖学的三维结构直接搬进诊室，帮助医生在手术前“预演”每一根椎间孔的走向。

Structural advantages of skeletal models

• Real rateThe vertebrae, which corresponds to the size of the adult population, can be seen in the direction of the thorax, vertebrae.
• Disable joints(b) Key areas such as shoulder rims and rims can be separated to allow for the observation of the spatial relationship of the stove to the surrounding organization.
• Neural Root MarkerEach nerve root is marked with a coloured silk line, with a transparent frame, which can be identified by a doctor when touching.

Clinical scenes

在骨科住院医师的轮转中，常见的椎间盘突出、骨折或先天性畸形，都可以先在模型上进行“手术模拟”。放射科医生则利用模型对比 X 光片、CT 或 MRI 的切面，快速定位异常椎体的具体位置。急诊科的年轻医生在面对多发创伤时，常常在模型上复盘，确认是否涉及到胸廓或骨盆的复合伤。

Data Support and Case

一项 2023 年《中华骨科杂志》发表的多中心对照研究显示，接受模型辅助训练的住院医师在椎体骨折判读准确率从 78%提升至 92%，平均用时缩短约 15 分钟。北京某三甲医院的脊柱外科团队报告，使用该模型进行术前规划后，手术出血量下降约 12%，住院天数缩短 1.3 天。

Outlook and challenges

尽管实体模型在空间感知上优势明显，但制作成本仍是限制普及的关键因素。随着 3D 打印材料的成本逐年下降，未来有望实现按患者个体解剖数据定制的专属模型。与此同时，如何将模型训练成果转化为影像诊断的算法输入，也是跨学科合作的方向。

Would it make clinical decision-making more like an accurate puzzle game by moving anatomy 'hardware' into the clinic?
