Scapulothoracic bursa
Also known as “snapping scapula syndrome”, arises when there is a problem with how the shoulder blade moves over the rib cage.
WHAT ARE THE CAUSES & RISK FACTORS?
The following are typical causes of snapping scapula syndrome:
- Overuse: Repetitive friction from overhead activities
- Muscle weakness: Less bulk between the ribcage and shoulder blade so they sit closer to each other.
- Posture: Avoid sustained forward flexed posture.
- Trauma: Injury to the surrounding area.
- Medical Conditions: Rheumatoid arthritis and other inflammatory diseases raise the risk of scapulothoracic bursitis.
- Poor Scapular Mobility: It could be caused by a nerve issue, a muscular deficiency, or another shoulder issue like a frozen shoulder.
- Bony Abnormality: The surrounding soft tissues will experience increased friction if the bones are not smooth. Examples include a tumor or more bone development.
