- Incision
- the patient is prone for this approach.
- an incision is made following at the posterolateral lip of the acromion, extends along the spine of the scapula, and turns at a right angle inferiorly along the medial border of the scapula.
- Superficial dissection
- the posterior deltoid is elevated off the spine of the scapula.
- Deep dissection
- the underlying infraspinatus is elevated off the medial border of the scapula and retracted laterally on its suprascapular neurovascular pedicle, while care is taken to protect the pedicle.
