"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."

Hand and finger joints

You use them every day, every day they help you with each step. Built from small joints, bones and ligaments, together they form two helping hands without which it is hard to get around. Get to know their structure and functions and learn more about prevention. 


The human hand consists of 27 bones. Three segments can be distinguished:

  • the wrist (carpal segment)
  • the five bones of the metacarpus
  • the fingers


The carpal bones are placed in two rows: 

  • a proximal row 
  • a distal row

Each of them composed of four bones.  


The proximal row consists of the bones

  • scaphoid
  • lunate
  • triquetral
  • pisiform bone (located on the triquetral bone on palmar side)


The distal row is formed with the bones:

  • the trapezium
  • the trapezoid
  • the capitate
  • the hamate


The mechanics of the hand is quite specific. The dysfunction of one bone automatically affects the dynamics of the other bones.


Construction of the hand and fingers


The hand owes its mobility to many joints, which include:

  • Radial-wrist joint- it is an ellipsoidal joint formed by the combination of the radial bone with the proximal row of carpal bones. It is reinforced by a radial-wrist ligament.
    Its function is inhibiting the movement of the elbow abduction of the hand

  • The mid-carpal joint serves as the connection between the carpal bones. The movements permitted with this joint are the palmar and  dorsum  flexion, radial and ulnar abduction and adduction.

  • The articular connection (joints) of the proximal row of carpal bones
  • The articular connections (joints) of the distal row of carpal bones
  • The carpometacarpal and  intermetacarpal joints  are the plane joints of minimal mobility. The thumb joint is an exception, since it permits the movement of abduction and adduction, as well as deviation, opposition, flexion , extension and hyperextension.
  • The finger joints (interphalengeal joints) belong to the group of  spheroidal (ball and socket) joints which do not permit the rotation movement.


A few words about the ligaments of the palm

Hands consist of several ligaments that are responsible for specific movements that we can perform.

  1. The collateral radius ligament of the wrist - is relatively short, but not too strong.
    Functions: inhibiting the ulnar abduction movement of the hand 

  2. Ulnar collateral ligament of the wrist - which is longer, but much weaker than the radial wrist ligament.
    Functions: inhibits movement of radial arm abduction

  3. Palmar radial wrist ligament - broad and very strong.
    Functions: inhibits the dorsal flexion and hand inversion movement

  4. Dorsal radial-wrist ligament - less regular and slightly weaker than the previous one
    Functions: limits the movement of palmar flexion and conversion

  5. Arched arcuate ligament of the wrist - it is created by the  connection of a part of the palmar-radial-wrist ligament -with ligament the palmar-wrist ligament
    Functions: inhibiting movement of dorsiflexion

  6. Curved dorsal wrist ligament - runs only between the bones of the wrist
    Functions: braking movements of palmar flexion and abduction



Ligaments: Palmar metacarpal ligaments, dorsal and interosseous are designed to strengthen the metacarpal joint capsules


The most common hand disorders


The rheumatoid disorders of the hand mostly occur in the area of:

  • The radiocarpal joint
  • The carpometacarpal joints 
  • The interphalangeal joints of fingers


The degenerative changes in the radiocarpal joint occur most commonly as a result of injuries in this area. The alterations are manifested as the Heberden’s nodes, developed on the dorsolateral surface of the fingers II - V of the distal interphalangeal joints (DIP)


The nodes in the proximal interphalangeal joints area are called Bouchard's nodes.


The finger joint dislocations mostly involve the dislocations in the proximal interphalangeal joints, caused by the injuries which lead to the joint hyperthropy.


The chronic rheumatic arthritis usually develops symmetrically in the wrists and joints of the hand, including the proximal interphalangeal joints. The disease is marked by pain, inflammation,  deformity and the impairment of movement, followed by degradation of the  joints or even the joints atrophy. The disease belongs to the group of autoimmune disorders and it mostly affects people at the age of 30—40 or older. The occurrence of the disease if fourfold higher among women than men.


Dupuytren's contracture is the disease marked by the fixed  contracture of the fingers in the flexed position,  accompanied by the occurrence of the characteristic  nodes in the  palmar fascia. The disease is prevalent  among men and it is most likely to affect the IV and V finger. It is marked by  the  fibrous nodes in the palmar fascia and mainly affects elderly people. It has genetic etiology.

Can the hand joints be exercised?

You can, and it's very easy. It is often recommended for example to exercise with a ball which is based on kneading it with both hands, transferring it between fingers or crushing in one hand.


Another exercise - put your hand and forearm on the table, not moving your wrist from the table move your fingers toward the wrist. Move your fingers forward to make them straight. When bending, the hand should forma distinctive peak. Repeat this exercise at least 20 times for each hand.


Regular exercise, especially when you've been diagnosed with rheumatoid arthritis or degeneration contribute to significant improvements in health. Without movement, the muscles weaken and produce contracture and the pain intensifies.
