Normal lumbar spine combination (four segments)

The normal lumbar spine combination (four segments) model is mainly used in medical teaching, anatomical demonstrations and clinical training to help learners gain a deeper understanding of the structure and function of the lumbar spine.

This model consists of four standard lumbar vertebrae, clearly presenting key structures such as the vertebral body, intervertebral disc, vertebral arch, vertebral foramen and intervertebral joints. It is also equipped with flexible materials to simulate the distribution of ligaments and nerve roots, allowing the physiological curvature and mobility characteristics of the lumbar vertebrae to be truly reproduced.

In teaching, students can observe the connection mode and movement patterns of the lumbar vertebrae through models, and master the stability and force characteristics of the lumbar vertebrae. In clinical training, the model can be used to demonstrate lumbar spine injury, degeneration and surgical approaches, etc., which is conducive to understanding the disease mechanism and treatment principle.

In addition, this model is also frequently used in rehabilitation teaching and spinal health education, helping the public intuitively understand the importance of lumbar spine health care, and has high teaching and popular science value.
