Impingement syndrome
Impingement Syndrome
Impingement Syndrome (pronunciation: im-pinj-ment sin-drohm) is a common condition affecting the shoulder, often seen in aging adults and those who engage in vigorous overhead activities. It is characterized by pain and loss of motion in the shoulder.
Etymology
The term "impingement" is derived from the Latin word "impingere" which means "to strike against". This is in reference to the way the tendons of the rotator cuff muscles become compressed, or "impinged" against the part of the shoulder blade known as the acromion.
Definition
Impingement Syndrome is a clinical syndrome which occurs when the tendons of the Rotator Cuff muscles become trapped and compressed during shoulder movements. This causes injury to the shoulder tendons and bursa resulting in painful shoulder movements.
Symptoms
Symptoms of Impingement Syndrome may include:
- Pain while lifting the arm
- Pain while doing activities that require overhead arm movements
- Weakness of the shoulder muscles
Causes
The primary cause of Impingement Syndrome is the narrowing of the bursal space between the Rotator Cuff and the Acromion. This can be due to:
- Aging
- Activities that require repetitive arm movements or overhead activities
- Structural abnormalities of the shoulder
Diagnosis
Diagnosis of Impingement Syndrome may involve:
- Physical examination
- X-rays
- MRI
Treatment
Treatment for Impingement Syndrome may include:
- Rest and avoiding activities that make the pain worse
- Physical therapy
- Medications
- Injections of a corticosteroid
- Surgery
