Frozen shoulder-how does it happen?
This condition was discovered in 1934 as”immobilization of the shoulder due to inflammation of the articular bag”. This term refers to diseases in which the main symptom is active and passive limitation of the range of motion. If the disease occurs without any cause, it is classified as a primary frozen shoulder. If the cause is detected, then it is said about the secondary form of “frozen shoulder”. In the initial form of this disease, the most important thing is the correct diagnosis to exclude any other pathologies.
The etiology of the primary form of frozen shoulder remains unknown. However, this disease is more common in diabetes, where the risk of this disease is estimated at 10-19% of the population with diabetes. The course of the frozen shoulder in diabetes is prolonged. Sometimes there is no complete retreat of the disease and to recover the full extent of the property. There is also an association with Dupuytren’s contracture in the hand, as patients with this condition have a much higher incidence of frozen shoulder.
Frozen shoulder often occurs after immobilization, trauma or surgery, but can also accompany inflammation of the shoulder joint, tendonitis causing calcification, or rotator cuff injuries. This condition also occurs as a result of micro – injuries, calcification in the tendon of the supraspinatus muscle, metabolic disorders, as well as as a result of the work performed-overloading the hands held up, jerking or pulling causing micro-injuries.
Do I have it or not? That is, the symptoms of a frozen shoulder
A typical symptom of a frozen shoulder is a limitation of active and passive mobility in the Panov-brachial joint. Movement is limited in all directions-there are problems with internal, external and reverse rotation. In the first stage of “freezing” the main symptom is pain, which appears suddenly, not as a result of injury and has no progressive character, but is also present at rest and intensifies at night.
There is inflammation of the joint bag, accompanied by a restriction of mobility. The stiffness felt in the pelvic-humeral joint is initially compensated by movement in the shoulder-thoracic joint, after which, over time, this compensation is visible in the form of distraction when trying to lift the shoulder. Symptoms of shoulder freezing include difficulty in performing small movements, such as placing your hands behind your back, and a sore arm is usually held in a prone position. The soft tissue layer surrounding the joint is often painful, which can lead to problems with the extensor and subscapular muscles.
