Can the elbow joint only perform flexion and extension movements?
Under normal circumstances, the elbow joint is not limited to flexion and extension movements but can also perform rotational movements. A detailed analysis is as follows:
The elbow joint is composed of the distal end of the humerus, the radial head, the joint capsule, ligaments, and other structures. Its primary function is to transport the hand to and stabilize it in required positions, which is achieved through various types of motion. In addition to flexion and extension, the elbow joint can also perform rotational movements, including ulnar and radial deviation. These movements enable individuals to carry out various daily activities smoothly, such as combing hair, washing the face, and using a keyboard.
In addition, appropriate elbow joint movement helps promote local blood circulation and enhances joint flexibility and stability. However, when performing elbow joint exercises, one should also avoid excessive force and potential injuries to prevent discomfort such as muscle soreness and joint pain.
