The role of the hip joint model lies in helping learners systematically master the anatomical structure, movement mechanism and clinical operation skills of the hip joint. It is an important tool for medical teaching, rehabilitation training and orthopedic clinical practice. This model is made in accordance with the real scale of the human hip joint, clearly showing the femoral head, acetabulum, joint capsule, ligaments and the attachment points of the surrounding muscles, and can visually present the structural relationship and range of motion of the joint. Through observation and operation, students can understand the movement principles of hip joint flexion, extension, abduction, adduction, rotation, etc., and at the same time master the basic concepts of joint injury, dislocation and replacement surgery.

In addition, hip joint models are usually designed to be detachable, facilitating teaching demonstrations, manual practice and surgical simulation operations. The model material is durable and has a certain degree of elasticity, which can simulate the movement resistance of real joints, allowing learners to repeatedly practice touch, Angle and technique in a risk-free environment. It not only enhances students' spatial cognitive ability of hip joint structure, but also provides intuitive references for clinical surgical operations and rehabilitation treatment. Overall, hip joint models are indispensable and important teaching AIDS in medical education and orthopedic training.
