Periarthritis Humeroscapularis, also called PHS syndrom or Painful shoulder syndrome, is all cases of shoulder pain and reduced functions because of different inflammatory and degenerative changes in soft tissues of the shoulder.
There is an inflammation of the joint capsule surrounding the shoulder joint. This results in pain, and the capsule enlarges and becomes thicker, resulting in curtailed freedom of movement of the shoulder. It is not known exactly what causes this condition, but the condition is thought to be associated with slight shoulder injuries, tendon inflammation or bursitis.
It is believed that around 2% of the population will be afflicted by a PHS during a lifetime, women are slightly more often affected than men. Frozen shoulder is seen mostly between the 40 to 60 years, and is equally frequent in both shoulders.
- Primary PHS (freezing)
In this stage, patients often feel: fatigue at the shoulder, increased pain in the movement, especially in the arm, when raise or scratch. The back has many difficulties, no swelling red at shoulder joint but patients feel pain when press at acromion, the front of the humerus, the tendon of the bipedal muscles; Shoulder movements are not restricted, or only limited by pain. X-ray scan of the shoulder joint is not unusual. The disease progresses lightly, decreases pain gradually after several weeks, but relapses easily.
- Secondary PHS (frozen)
In frozen form, the symptoms of pain begin to worsen, pain develops and restricts the shoulder motion due to joint stiffness, lasting from months to years with these expressions: pain decreases, but movement restriction increases, the movement is limited, the disease’s extension can produce muscular atrophy due to reduced mobility.
- Scapulo-humeral syndrome:
People suffering from shoulder-to-hand syndrome will be affected by inflammation around the arthritis. In this stage, the pain is produced by congestion and vasomotor disorders in the hand. Patients suffer pain and limitation of shoulder joint motion blockage. The patient's hands begin to suffer from a vasomotor vasodilatation: leading to swollen forearms, forelimbs, purple or purplish skin, and chilly skin. Aching both hands day and night. Thin nails, fragile and brittle. The muscles of the hands begin to have significant atrophy, from which all hand movements and fingers begin to become confined to daily life.
The disease progresses from 6 months to 2 years, the symptoms gradually decrease but then leave the post-treatment, muscle tone reduction and limitation of hand movement. In some patients with recurrent illnesses when moving strongly to the shoulders or hands.
