FROZEN SHOULDER Overview
WHAT IS FROZEN SHOULDER?
Frozen shoulder is a painful condition in which the shoulder becomes stiff and movement becomes limited. Frozen shoulder occurs when the supporting structure around the shoulder joint (capsule) becomes thick, stiff, and inflamed.
The condition is called "frozen" shoulder because the more pain that is felt, the less likely the shoulder will be moved. Lack of use causes the shoulder capsule to thicken and becomes tight, making the shoulder even more difficult to move and so it is "frozen" in its position.
Primary: Primary frozen shoulder is “out of the blue” frozen shoulder, occurring without any obvious connection to any other condition.
Secondary: Secondary cases appear following other medical problems, such as an injury to the area, the onset of diabetes, or even a surgery that has nothing to do with the shoulder.
Both types probably involves the same underlying vulnerability, but some triggers are more obvious than others.
- Age: Adults, most commonly between 40 and 60 years old.
- Gender: More common in women than men.
- Recent shoulder injury: Any shoulder injury or surgery that results in the need to keep the shoulder from moving.
- Diabetes: Having diabetes increases the chance of having frozen shoulder.
- Other health diseases and conditions: Includes stroke, hypothyroidism (underactive thyroid gland), hyperthyroidism (overactive thyroid gland), parkinson’s disease and heart disease.
If left untreated, frozen shoulder may cause:
- Pain in the shoulders
- Loss of mobility
- Reduced range of motion
- Muscle trouble that can worsen and persist for a long time
Complete immobilization is also a common complication of frozen shoulder.
