Elbow Joint

The elbow joint (elbow) is a complex block-shaped joint formed by the articular surfaces of the epiphysis (lower and upper epiphyses) of the humerus and the bones of the forearm (ulna and radius).

This joint allows flexion and extension of the forearm relative to the shoulder. It consists of three separate joints - the elbow, radioulnar and humeroulnar.

The elbow joint includes:

1. Lower epiphysis of the humerus
2. Upper epiphysis of the ulna

The radioulnar joint is formed by:

1. Upper epiphysis of the radius
2. Lower epiphysis of the humerus

The ulnohumeral joint is located between:

1. Lower epiphysis of the humerus
2. Upper epiphysis of the ulna

The joint capsule covers all three joints, ensuring their interconnection and overall mobility.

The elbow joint is a common site for fractures and dislocations due to its complex anatomy and susceptibility to injury. Proper treatment of injuries to this joint is essential to restoring normal function of the upper extremity.

The Elbow Joint, or Elbow Joint, is a complex block-shaped joint of our body, which is formed by the articular surfaces of the humerus and forearm bones - the ulna and radius. This joint is located in the elbow and is a typical site of fracture and dislocation.

The structure of the elbow joint includes three main components: the humerus (humerus), the ulna (ulna) and the radius (radius). The articular surface of the humerus is formed by two epiphyses, which connect to the ulna and radius. The ulna, in turn, also has two articular surfaces that connect to the radius and ulna.

The elbow joint is where flexion, extension, rotation and adduction and abduction of the arm occur. It is also responsible for maintaining balance and stability of the body.

However, the elbow joint can be easily injured during physical activities such as heavy lifting, running, jumping and other activities. Fractures and dislocations of the elbow can lead to pain, limited mobility, and even disability. Therefore, it is important to be careful not to put excessive stress on the elbow joint.

The elbow joint or elbow joint is one of the most complex joints in its structure, since it connects the human arm bone with the radius and ulna bones. In the medical literature, this joint is also called the trochlear-ulnar joint. It received this name largely because in appearance it resembles an acute angle.

The structure of the elbow joint includes the radius and ulna bones, humeral parts of the bones, intra-articular cartilaginous and spongy parts, extra-articular ligaments, capsule and synovial membrane of the joint. The ligaments of the elbow joint are its well-developed frame and provide friction between its various components. In addition, there is a special connection that separates the external and internal components.

Since the elbow joint is a trochlear-ulnar joint, it can be compared to a separate block that is placed in the large manubrium area. The function of this joint is to flex and extend the limb by forming the required angle, both in one plane and in several. If we talk about the functional significance of the elbow joints for a person, then without them it would be impossible to freely raise the arms, as well as make movements in the area of ​​the shoulder and wrist. That is, blocking the elbow joints is an absolutely necessary condition for the development of modern technology and means for work and communication between people.
