Causes of Thoracic Inlet Syndrome

Thoracic Inlet Syndrome(TIS) can be attributed to several factors that lead to the compression of neurovascular structures in the thoracic inlet. The main causes include:

  1. Anatomical abnormalities: Some individuals are born with an extra cervical rib, elongated C7 transverse process, or an abnormal fibrous band connecting the spine to the rib. These anomalies can reduce the space available for the neurovascular structures and cause compression.
  2. Poor posture: Slouching or maintaining a forward head posture can lead to muscle imbalances and strain in the neck and shoulder area, contributing to TIS.
  3. Repetitive activity: Overuse or repetitive movements, such as typing or playing certain sports, can cause inflammation and compression of the neurovascular structures in the thoracic inlet.
  4. Trauma: Injuries to the neck, shoulder, or clavicle may cause TIS due to inflammation, scar tissue, or displaced bones.
  5. Pregnancy: Hormonal changes and increased fluid retention during pregnancy can cause swelling and compression in the thoracic inlet.
