"I can sleep peacefully all night and it has not been possible before. What is important, with Hyalutidin, there was no stomach discomfort, which is important in pharmacological treatment. The product is well worth the money. "

Wanda Bąk

"After 30 days of starting supplementation, we observed a significant reduction in unpleasant knee friction. Moreover, the patient also stopped complaining about knee pain. The above case encouraged me to further recommend Hyalutidin to patients undergoing rehabilitation. "

Łukasz Hawełka

" My 82-year-old father-in-law after a month's treatment forgot about pain and restored his mobility, so I can recommend this preparation with a clear conscience."

Elbow joint

The elbow joint (articulatio cubiti ) is a complex joint. It consists of three articulations which are anatomically joined  and enveloped by the common joint capsule. They include: 

  • the humeroulnar joint
  • the humeroradial joint
  • the proximal  radiournal  joint 

The cubital joint belongs to the group of hinge joints.

 

Elbow joint construction in detail

Let's start with the most important issue - namely, the elbow joint has one joint capsule, in which 3 connection joints actually interact. Disruption of any one of them may lead to higher dysfunction of an upper limb, including hand restraint. The joint capsule also constitutes protection and stabilizes the joint in the extreme positions of the bones towards each other. Mainly, however, it is ligaments that constitute the stability of the joint. Both structures due to their function are exposed to high loads and therefore are often damaged during injuries.
 

The ligaments which connect the joints are:

  • the ulnar collateral ligament
  • the radial collateral ligament

 

The head of the humeroradial joint is the head of the humeral bone,  while its socket is the trochlear notch of the radius. The radiournal  joint has the articular head on the articular circumference of the radial bone, whereas its socket is located on the radial notch of the ulna.

The elbow joint is surrounded by the joint capsule, which protects the joint against the influence of external factors,  but  its main purpose is to produce the synovial fluid which is a nutritious  and lubricating substance, reducing friction on articular surfaces. The joint capsule also serves as a stabilizer of the joint in cases of the extreme position or displacement of the bone elements in relation to each other 

This joint is not stabilized by the muscles, thus the ligament structures play a significant role here, since they are exposed to the large load during the force strain displacement, especially in lateral directions. Both the ligaments and the joint capsule, serving as the main elbow stabilizers, are particularly vulnerable to the damage during injuries.

 

 

Elbow joint construction

 

The structures which are responsible for the elbow movement are the muscles surrounding the joints. They can be divided into the following groups: 

  • anterior - so called “flexor muscles" in the elbow (permitting flexion)
  • posterior - the muscles which permit extension movement in the elbow
  • lateral- the muscles  which permit the extension of the wrist and fingers
  • medial - the muscles which permit the flexion of the wrist and fingers

 

The pathology of the elbow joint

The most common pathology is so called 'tennis elbow' (Lateral epicondylitis) .  It is marked by the characteristic pain in the lateral part of elbow during gripping. The inflammation of the lateral epicondyle of the humeral bone is mostly caused by the overexertion of the wrist and fingers  extensors. The disease usually affects men. The overexertion  or the repetitive injuries may lead to the fibrosis and micro-tears of the exposed tissues.  The motion which induces the symptoms  is the resisted wrist extension,  combined with the forearm pronation, or the attempts to lift the chair.

The bursitis (inflammation of bursae) is a disorder occurring mostly as a result of the excessive pressure. The main function of bursa is to reduce friction. The synovial bursa prevents the excessive friction, lubricates joints and facilitates the free sliding  of the muscles and ligaments during movement. The inflammation of the bursa causes the symptoms of pain and swelling of the joint, which are increased by movement.

 

Degenerative joint disease (osteoarthritis) may affect any joint and it includes the degenerative changes of both the articular surfaces and the tissues which surround them. It leads to the loss of the joint movement capabilities.  The disease is caused by the damage to the articular cartilage ( protective layer surrounding the bones in the joints), followed by the damage to the bone covered by the cartilage. This kind of damage leads to the inflammation of the surrounding tissues.

 

A sprain is the dislocation of the articular surfaces relative to each other,  along with the tearing of both the joint capsule and ligaments. As for the sprained elbow, it usually occurs as a result of the falling on the outstretched arm.

 

Prevention 

It is always better to prevent, little hints with a big effect:

- are you working in front of the computer? It is worth to use a pad that will ensure free falling of the hand on the mouse or the keyboard. This way, only the fingers are working, and you do not feel constant tension in the wrists

- strengthen the muscles straightening the wrist when screwing in light bulbs - it is a simple exercise involving imitating the movement of screwing the bulb with a bended elbow. An exercise which is the perfect workout.
