The lumbar vertebrae with caudal vertebrae model is an important teaching aid commonly used in medical education and clinical training, which is of great significance for visually presenting the overall structure of the lumbar vertebrae, sacral vertebrae and caudal vertebrae. This model can clearly present the spatial relationship of the vertebral body, intervertebral disc, vertebral foramen and spinal canal, helping learners systematically understand the anatomical characteristics and mechanical structure of the lower lumbar spine, and is conducive to mastering the anatomical basis of human weight-bearing, movement and stability.

In teaching, models are widely applied in anatomy, orthopedics, rehabilitation medicine and nursing instruction. They can be used to explain the occurrence mechanisms of common diseases such as lumbar degeneration, intervertebral disc protrusion and sacrococcygeal injury, thereby enhancing students' comprehension ability and memory effect. In clinical practice training, the lumbar caudal vertebral model can also be used to demonstrate operations such as lumbar puncture and epidural anesthesia, helping medical staff accurately identify body surface positioning and reduce operational risks. Meanwhile, this model is also applicable to patient education, enabling patients to have a more intuitive understanding of their own lesion sites and treatment plans, and it has high teaching and application value.
