"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."

Shoulder joint

The shoulder joint (the glenohumeral joint) is a junction between the humeral bone and the scapula. The articular surfaces are formed with the head of the humeral bone and the glenoid cavity (glenoid fossa) of scapula (which forms the joint socket.) The glenoid cavity is covered with the hyaline cartilage, its edge is surrounded by the fibrocartilaginous structure of glenoid labrum which deepens the cavity and facilitates the mobility of the joints.


Construction of the shoulder joint


The acetabular articular surface is increased so that there is large joint mobility.

Due to the difference between the size of the head and the cavity, as well as  the large mobility of the joint, the joint capsule forms a kind of the loose, capacious sack. The muscles which rotate the shoulder (e.g. subscapularis, supraspinatus, infraspinatus, teres minor) surround the articular capsule and are connected to it,  thereby protecting and strengthening it - they provide the active protection of the capsule.

The ligament of the shoulder joint

The passive ligaments reinforce the articular capsule.

The coracohumeral ligament (ligamentum coracohumerale) is a broad, strong and flat ligament which is attached to the base and posterior border of the coracoid process and to  the greater and the lesser  tubercle of the humerus.

  • This ligament limits the adduction movement and bears the shoulder in the normal, lowered position, preventing the detachment of the humerus head from the cavity.
  • The Glenohumeral ligaments, (the superior, middle, and inferior ligaments) are articulated in the same way as the fibrous membrane of the joint capsule.


Synovial bursae

A number of synovial bursae are located in the area of the shoulder joints. They are filled with the fluid which resembles the synovial fluid both in its content and consistency, and their function is to  reduce friction and allow the free movement of the particular elements of the shoulder. The bursae located in the shoulder joint are:

  • the bursa of the long head of the biceps
  • the subtendinous bursa of the subscapular muscle
  • subacromial bursa
  • the bursa of the coracobrachialis muscle


Movement of the shoulder joint

The shoulder joint is the ball and socket type of joint which allows a large range of motions in the shoulder, such as:

  • the adduction and abduction
  • the upward elevation of the arm 
  • extension, circumduction
  • the medial (internal) and lateral (external) rotation.


Chodź zawsze wyprostowany - utrzymanie odpowiedniej postawy ciała jest istotne dla kręgosłupa ale także stawów barkowych. Wymuszona, nienaturalna pozycja utrzymywana przez długi czas prowadzi do wyłączenia z użytku niektórych mięśni, co ma wpływ na stabilność stawu.



The most common injuries of the shoulder joint.

Impingement syndrome - it is a pathology leading to the inflammation of the subacromial bursa. The first symptoms are the pain in the acromion, occurring after  physical effort. The disorder develops mainly as a result of the imbalance between the deltoid muscle and the rotator cuff muscles (the stabilizers of the shoulder joint)


The rotator cuff injuries - the rotator cuff  is the element which connects the muscles arising from the scapula up to the humerus. As a result of the muscle overload or the repetitive micro-injuries, the weakening or the tear of the rotator cuff may occurs, (so called ‘wear and tear’). The main symptoms include the shoulder pain, the restricted range of the arm movement and the reduction of the shoulder endurance.


The shoulder instability  - it refers to the ailment when, during movement, the structures surrounding the joint  fail to keep the ball tightly within its socket, which leads to the painful dislocation of  the humerus head in the socket. The episodes of the repetitive dislocation and subluxation (shoulder dislocation) may be followed by the uncomfortable sense of the shoulder instability or even the acute pain and the self-imposed restriction of movement,  caused by the apprehension of the re-occurrence of the episode. The shoulder instability is usually the effect of the first traumatic shoulder dislocation sustained by the young people.
