The indispensable role of hand skeletal joint model in medical education is mainly due to its unique value in deepening students' understanding, improving practical skills and promoting the integration of theory and practice.

Firstly, the articular model of the hand bone greatly reduces the difficulty for students to understand the complex anatomical structure of the hand due to its intuitiveness and palpability. The hand skeleton consists of many small bones, which are connected to each other by precise joints, forming a highly flexible and versatile hand structure. For beginners, it is often difficult to form a clear three-dimensional concept only from the text and pictures on the book. The hand bone and joint model can truly restore the anatomical form of the hand, so that students can directly observe, touch and even operate these bones and joints, so as to more intuitively understand their structure and function.

Secondly, the hand skeletal joint model plays an important role as a practical tool in medical education. Medicine is a highly practical subject, and students need to improve their skills and experience through continuous practice. The hand skeletal joint model provides students with a safe, controlled practice environment in which they can practice hand anatomy, simulation of joint movement, and surgical procedures without contact with real patients. This practical training not only helps improve students' operational skills, but also develops their clinical thinking and decision-making abilities.

In addition, the hand bone joint model also promotes the close integration of medical theory and practice. In traditional medical education, there is often a disconnect between theory and practice. The hand bone joint model provides a bridge for students, enabling them to deepen their understanding of theoretical knowledge through practical operation while learning theoretically. This combination of theory and practice is helpful to improve students' comprehensive quality and clinical ability.

To sum up, the hand skeletal joint model plays an irreplaceable role in medical education. It can not only help students understand hand anatomy more intuitively, improve practical skills, but also promote the close combination of theory and practice, and provide strong support for cultivating outstanding medical talents. Therefore, the extensive application of hand skeletal joint model in medical education is of great significance for improving the quality of medical education and training high-quality medical talents.
