Frozen shoulder, also called adhesive capsulitis, causes pain and stiffness in the shoulder. Over time, the shoulder becomes very hard to move. Frozen shoulder occurs in about 2% of the general population. It most commonly affects people between the ages of 40 and 60, and occurs in women more often than men. In frozen shoulder, the shoulder capsule thickens and becomes tight. Stiff bands of tissue — called adhesions — develop. In many cases, there is less synovial fluid in the joint.
The hallmark sign of this condition is being unable to move your shoulder – either on your own or with the help of someone else.
It develops in three stages: Freezing In the”freezing” stage, you slowly have more and more pain. As the pain worsens, your shoulder loses range of motion. Freezing typically lasts from 6 weeks to 9 months.
Frozen, painful symptoms may actually improve during this stage, but the stiffness remains. During the 4 to 6 months of the “frozen” stage, daily activities may be very difficult.
Thawing shoulder motion slowly improves during the “thawing” stage.
Complete return to normal or close to normal strength and motion typically takes from 6 months to 2 years.
Cause & Symptoms
The causes of frozen shoulder are not fully understood. There is no clear connection to arm dominance or occupation.
A few factors may put you more at risk for developing frozen shoulder.
Diabetes. Frozen shoulder occurs much more often in people with diabetes, affecting 10% to 20% of these individuals. The reason for this is not known.
Other diseases. Some additional medical problems associated with frozen shoulder include hypothyroidism, hyperthyroidism, Parkinson’s disease, and cardiac disease. Immobilization. Frozen shoulder can develop after a shoulder has been immobilized for a period of time due to surgery, a fracture, or other injury. Having patients move their shoulders soon after injury or surgery is one measure prescribed to prevent frozen shoulder.
Pain from frozen shoulder is usually dull or aching. It is typically worse early in the course of the disease and when you move your arm. The pain is usually located over the outer shoulder area and sometimes the upper arm.
Your Great Lakes Orthopedics & Sports Medicine orthopedic surgeon will test the range of motion in your shoulder. After discussing your symptoms and medical history, he or she will examine your shoulder. Your doctor will move your shoulder carefully in all directions to see if movement is limited and if pain occurs with the motion. The range of motion when someone else moves your shoulder is called “passive range of motion.” Your doctor will compare this to the range of motion you display when you move your shoulder on your own (“active range of motion”). People with frozen shoulder have limited range of motion both actively and passively.
Other tests that may help your doctor rule out other causes of stiffness and pain include:
X-rays. Dense structures, such as bone, show up clearly on x-rays. X-rays may show other problems in your shoulder, such as arthritis.
Magnetic Resonance Imaging (MRI) and ultrasound. These studies can create better images of problems with soft tissues, such as a torn rotator cuff.
