Clavipectoral Fascia (Chest Region)

fascia clavipectoralis (regio thoracis)

The clavipectoral fascia of the chest region specifically refers to the portion below the pectoralis minor that encloses the axillary contents and forms the suspensory ligament of the axilla, creating the axillary dome.

Region: Chest
Biomechanics

Function & Actions

Forms the floor of the clavipectoral triangle and the anterior wall of the axilla below the pectoralis minor, suspends the axillary skin via the suspensory ligament, and encloses the axillary vessels and lymph nodes in the lateral axillary wall.

Clinical Relevance

Clinical Notes

In axillary lymph node dissection for breast cancer, the clavipectoral fascia is entered to access the axillary contents. Axillary web syndrome (cording) after ALND involves fibrosis of the clavipectoral fascial connections, producing a tight band limiting shoulder abduction.
