Lateral:

Laterally, it becomes thick and dense and attaches to the coracoid process.

Above:

It splits to enclose the subclavius and attaches to the lips of the subclavian groove of the clavicle.

Below:

It splits to enclose the pectoralis minor, and thereafter it continues downward as the suspensory ligament of the axilla, which is attached to the convex dome of the axillary fascia.

Clavipectoral Fascia Modifications

• Costocoracoid ligament: Thickening of clavipectoral fascia between coracoid process and 1st rib.
• Suspensory ligament of the axilla (vide supra).

Clavipectoral Fascia: Functional significance

Acts as a suspensory ligament of the axilla to maintain its concavity.

Clavipectoral Fascia Applied Anatomy

The cancer cells from breast may pass across the clavipectoral fascia to invade the Rotter’s lymph nodes lying in front of pectoralis minor muscles. Hence, the knowledge of clavipectoral fascia is of great surgical significance.
