Shoulder Impingement Syndrome

This condition occurs when the tendons of the rotator cuff, along with the subacromial bursa, become compressed against a bony scapula protrusion called the acromion. As these tissues continually rub against bone, they become irritated and inflamed.

Cause
This condition is typically caused by excessive use of the shoulder. Occupations such as painting or construction, which require repetitive overhead motions, are common culprits.

Symptoms
Clavicle fractures can be very painful and may make it hard to move your arm.

Additional symptoms include:

• Tenderness
• Reduced range of motion
• Weakness in the shoulder
• Minor pain may be present even when the shoulder is at rest
• Sudden, sharp pain may be felt when the arm is use

Treatment

If non surgical options do not relieve the symptoms, surgery may be needed to create space in the shoulder.
