How does the elbow joint model show how the elbow joint moves?



Elbow joint model presents the complex biomechanical properties of elbow joint through elaborate design and simulation. Here is a detailed explanation of how the elbow joint model shows how it moves:

Simulate flexion movement:

The main movement of the elbow joint is flexion and extension. The elbow joint model demonstrates the flexion and extension of the elbow by simulating the relative motion of the lower end of the humerus (trochlea and capitulum of the humerus) with the upper end of the ulna and radius (notch of the trochlea of the ulna and fossa of the radius). These simulated structures allow the model to perform smooth flexion and extension movements within a specific range of angles, thereby visually demonstrating the flexion and extension function of the elbow joint.

Simulate pronation and supination:

In addition to flexion and extension, the elbow joint also has the function of pronation and supination. This mainly involves the relative rotation between the radius and ulna. The elbow joint model demonstrates pronation and supination of the forearm by simulating the relative rotation between the annular articular surface of the radius and the radial notch of the ulna, and the rotation of the ulnar notch around the ulnar bone. This simulation allows the model to demonstrate the rotation function of the elbow joint that is crucial in daily life and movement.

Combining flexion and rotation:

In actual motion, flexion and rotation of the elbow joint often occur at the same time. The elbow joint model can simulate this composite movement, such as forearm pronation during elbow flexion or forearm pronation during elbow extension. This simulation contributes to a more complete understanding of how the elbow joint performs in complex movements.

Structural details and range of motion:

Elbow joint models usually have fine structural details, such as joint capsules, ligaments, muscle attachment points, etc., which have important effects on the stability and range of motion of the elbow joint. The model can use these structural details to show the stability and range of motion of the elbow joint in different motion states.

Dynamic display and interactive teaching:

Modern elbow models may also feature dynamic displays and interactive teaching. For example, through electric or manual control, the model can simulate the movement of the elbow joint at different speeds and angles, while interactive learning with instructional software or videos helps students gain a deeper understanding of how the elbow joint moves and its biomechanical propert ...
