Thoracic Outlet Syndrome
What is Thoracic Outlet Syndrome?
In general, the cause of thoracic outlet syndrome is compression of the nerves or blood vessels in the thoracic outlet, just under your collarbone (clavicle). The passageway for these nerves and blood vessels to exit the chest and supply the upper extremities is referred to as the thoracic outlet. Muscle, bone, and other tissues border the thoracic. Any condition that results in enlargement or movement of these tissues of or near the thoracic outlet can cause the thoracic outlet syndrome.
What causes Thoracic outlet syndrome?
The cause of the compression varies and can include:
• Anatomical defects. Inherited defects that are present at birth (congenital) may include an extra rib located above the first rib (cervical rib) or an abnormally tight fibrous band connecting your spine to your rib.
• Poor posture. Drooping your shoulders or holding your head in a forward position can cause compression in the thoracic outlet area.
• Trauma. A traumatic event, such as a car accident, can cause internal changes that then compress the nerves in the thoracic outlet. The onset of symptoms related to a traumatic accident often is delayed.
• Pressure on your joints. Obesity can put an undue amount of stress on your joints, as can carrying around an oversized bag or backpack.
• Pregnancy. Because joints loosen during pregnancy, signs of thoracic outlet syndrome may first appear while you’re pregnant.
The primary treatment used by a chiropractor is the chiropractic adjustment. The chiropractic adjustment is low amplitude, high-velocity, focused thrust that reestablishes correct motion to a joint. The chiropractic adjustment can be performed on any joint in the body. The foremost location treated with a chiropractic adjustment for the restoration of skeletal movement is the spine.
