A common cause of shoulder joint pain is impingement. Impingement occurs when structures within the shoulder (such as tendons and bones) rub together, this is called tendonitis. Tendonitis of the shoulder blade is often referred to as Swimmer’s shoulder. Generally, external impingement occurs, where the rotator cuff intrudes into the sub-acromial space.
The space between the acromion and the rotator cuff is filled with the sub-acromial bursa, a fluid-filled sac that allows the shoulder to move properly. Any unusual impact on the rotator cuff can cause shoulder joint pain and impingement.
Conditions that can impact the function of the rotator cuff, and potentially cause impingement include:
Symptoms of impingement or rotator cuff injury include:
Your orthopaedic doctor will check your shoulder for tenderness, and check the function and strength of your arm and shoulder. He will rule out other potential conditions such as arthritis before proceeding with available treatment options. Your doctor may also use x-rays, ultrasound or magnetic resonance imaging (MRI) to check for abnormalities.
Some non-surgical treatments for Swimmer’s shoulder include:
If all treatment options have been exhausted, and there is no pain relief, your orthopaedic surgeon may recommend shoulder impingement surgery otherwise known as rotator cuff surgery. The surgical procedure will help to create more space for the rotator cuff. Your surgeon will remove a part of the acromion as well as the inflamed part of the bursa, ultimately minimising the pain in your rotator cuff. In this case, Dr Pirjol will conduct arthroscopy, during which he will insert a small camera into your shoulder joint. Images will then be displayed on screens as he guides small surgical tools with the use of a monitor.
