Tendinitis -
Rotator Cuff Tendinosis

What is the rotator cuff?

 

The rotator cuff is a set of four tendons that form a “belt” around the shoulder.

They help stabilize the joint and are involved in various lifting and rotation movements, being constantly required for the various functions of the arm.

Tendinitis, tendinosis, tendinopathy. What are the differences?

Tendinitis indicates an inflammation of the tendons, while tendinosis refers to the process of tendon wear and tear and degeneration. Although used interchangeably, they are biologically distinct terms that can be grouped together under what is described as tendinopathy – a more generic term that refers to any painful condition of the tendons caused by overload.

 

What is rotator cuff tendonitis?


The rotator cuff tendons can be involved in a process of wear and inflammation resulting from repetitive movements, excessive loads, “pinching” of the tendon (conflict) or even the natural process of tendon aging.

 

What are the symptoms of rotator cuff tendonitis?


These changes often do not cause symptoms and can occur silently.

However, shoulder pain can develop gradually over time and can be a major cause of disability. In addition to affecting professional performance, nighttime pain is common and can significantly disrupt sleep, increasing the impact on well-being and quality of life.

 

How can I distinguish rotator cuff tendonitis pain?


The pain of shoulder cuff tendonitis usually does not have an easily identifiable onset, but develops insidiously and worsens progressively over time or after certain efforts. The pain is most often reported in the lateral region of the shoulder, but is commonly associated with pain radiating to the cervical region and back, as well as to the rest of the arm and even the hand. Nighttime pain is common and may even make it impossible to sleep on the affected side or wake the patient during the night.

 

What are the treatments for rotator cuff tendonitis?


Non-surgical treatment is considered the first line of treatment, since most cases improve significantly with this type of treatment.  Surgical treatment is reserved for cases where pain and persistent disability persist after several months of conservative treatment.
