The natural large pelvis with five lumbar vertebrae model is mainly used in medical education, anatomy teaching and clinical training, truly reproducing the structural characteristics of the human pelvis and lumbar vertebrae region. The model is made based on the anatomical scale of the human body, including a complete pelvis, sacrum and five movable lumbar vertebrae. It can clearly display the physiological curvature of the lumbar vertebrae, the intervertebral structure and the connection relationship between the pelvis and the spine

In teaching applications, this model is often used to explain the anatomy, physiological functions and related lesions of the lumbar vertebrae, such as intervertebral disc protrusion, lumbar spondylolisthesis and pelvic malformations. Students can gain a deep understanding of the movement laws and mechanical relationships between bones through observation and manual operation, thereby enhancing the intuitiveness and practicality of theoretical learning. In clinical training, the model is also used to guide orthopedic, rehabilitation and nursing professionals in performing skills such as lumbar spine positioning, body position placement and pelvic measurement.

In addition, this model is also frequently used in health education and scientific research demonstrations to help patients understand the structure of the spine and the mechanism of disease formation. Through the application of this model, learners can systematically master the structure and function of the lumbar vertebrae and pelvis, providing a scientific basis for clinical diagnosis and rehabilitation treatment.
