How and why does the body create adhesion?

Think back to the last time you had a cut that resulted in a scar...


What happens when you cut your finger? Obviously, it is going to bleed. Eventually, the blood becomes sticky and that stickiness is the "fibrin" being laid down. This stops the bleeding and lays down the foundation for the cut area to be filled in. But what ends up binding together that cut skin? It is SCAR tissue, not skin.

What happens when you damage the muscles in your shoulder, such as your rotator cuff? It actually bleeds and may also become inflamed. Bleeding and inflammation lead to the same sticky glue that you get after cutting your finger.


1. Injury and Bleeding. Injuring just a few microscopic strands of muscle leads to bleeding. Bleeding signals fibroblasts to come into the area and begin preparing the scar-tissue adhesion
The entire injured area within your shoulder then becomes 'sticky'. Sticky "fibrin" glue seeps throughout the layers of damaged muscle. As the healing process completes itself, the glue leads to a tough scar tissue buildup.

The big problem with this process is that the body isn't very meticulous about what it 'glues' together. What happens most of the time, is it glues all the tissue in the area back together...whether it's damaged or not.


2. The Spread of Sticky Fibrin. The Fibroblast cells and sticky fibrin glue seep throughout the INJURED TISSUE as well as throughout the HEALTHY TISSUE.
"Shoulder Injuries lead to damaged tissue as well as healthy tissue adhering together...hence the term 'adhesion'."
What's the difference between scar tissue and muscle tissue? Does this adhesion / scar tissue work the same as muscle? Can it contract like muscle? Is it as flexible as muscle? The answer is again, "No." The scar tissue adhesion is less flexible, cannot contract, constricts blood flow and can prevent the muscle from functioning like it should.
3. Scar Tissue and Adhesion Forms. Damaged tissue as well as healthy tissue adheres together...hence the term 'adhesion'.
