Suspensory ligament of axilla

Suspensory ligament of axilla

The suspensory ligament of axilla is a significant anatomical structure within the axilla (armpit) region. It plays a crucial role in maintaining the contour and function of the axilla.

Anatomy

The suspensory ligament of axilla is a fibrous band that extends from the clavipectoral fascia to the skin of the axilla. It is part of the deep fascia of the upper limb and contributes to the formation of the axillary fossa.

Function

The primary function of the suspensory ligament of axilla is to support the skin and subcutaneous tissue of the axilla. It helps in maintaining the concave shape of the axillary fossa, which is essential for the mobility and function of the upper limb.

Clinical Significance

In clinical practice, the suspensory ligament of axilla is important in various surgical procedures, particularly those involving the breast and lymph nodes. It is also relevant in the context of axillary lymph node dissection and mastectomy.
