How human bone models support clinical diagnostic training

In the anatomy lab in the school building, a model of 175 cm, marked by the neurological root, is being surrounded by a resident. It is not a mere decoration, but a three-dimensional structure of anatomy is moved directly to the clinic to help the doctor "preprepare" the direction of each vertebrae before the operation.

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

In the rotation of an osteoporator, "surgery simulations" can be performed first on models for common intervertebral discs, fractures or congenital malformations. Radiologists use models to compare the cut side of X-rays, CT or MRI to quickly locate the location of the abnormal vertebrae. In the face of multiple trauma, young doctors in emergency care often reset the model to confirm whether a plethora or pelvis injury was involved.

Data Support and Case

A multi-centre comparative study published in 2023 by the Chinese Osteroid Journal showed that the interpretation accuracy of vertebrae fractures increased from 78 per cent to 92 per cent, with an average time reduction of about 15 minutes. The spinal surgery team at a Beijing hospital reported a decrease of approximately 12 per cent in surgical haemorrhage and 1.3 days in hospital days following pre-operative planning using the model.

Outlook and challenges

Despite the obvious advantages of physical models in space perception, production costs remain a key factor limiting access. As the cost of 3D printed materials declines year by year, it is expected that in the future an exclusive model tailored to patient-specific anatomy data will be achieved. At the same time, the translation of model training results into algorithms for video diagnostics is the direction of interdisciplinary cooperation.

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