Extent:
- Between subclavius and pectoralis minor
- Deep to pectoralis major (which is enclosed anteriorly by pectoral fascia)
Function:
- Acts to suspend the floor of axilla
- Encloses 2 muscles – subclavius and pectoralis minor
Structures piercing the clavipectoral fascia:
Mnemonic: CLAP
- Cephalic vein
- Lymphatics (passing between infraclavicular and apical nodes of axilla)
- Acromiothoracic artery
- Pectoral nerve (lateral)
Surgical relevance:
- Joint immobility after shoulder arthroplasty – one of the factor is replacement of true clavipectoral fascia by fibrotic tissue.
