The spine with pelvis and hemileg bone model is a comprehensive teaching tool used for anatomy instruction and clinical training. It combines and presents the main bony structures of the spine, pelvis, and one lower limb, helping learners to have a more systematic understanding of the skeletal relationships in the lower body of the human body.

Through the model, the arrangement of the cervical vertebrae to the sacral vertebrae, the morphology of the pelvic cavity and the structure of the acetabulum can be clearly observed. At the same time, the connection mode of the femur and its mechanical relationship with the pelvis are demonstrated, which is convenient for understanding the force line transmission of actions such as standing and walking.

In teaching, models can assist in explaining knowledge points such as the physiological curvature of the spine, anterior and posterior pelvic tilt, and the range of motion of the hip joint, enhancing students' understanding of three-dimensional anatomical structures.

In terms of clinical training, it holds significant value for related specialties such as orthopedics and rehabilitation. It can be used as a teaching tool to explain the causes of lumbar pain, hip joint disorders, and mechanical abnormalities of the lower extremities, which helps learners establish a more complete clinical thinking system.
