The Shoulder

Technique:

• The patient sits, the arm hanging in a neutral position.
• The lateral edge of the acromion and coraco-acromial ligament is identified.
• A thin needle, 5 cm long, is inserted about one cm under the acromial edge.
• The needle is then further moved, in a slightly cranial direction under the acromion.
  If resistance is felt before it has passed to nearly its full length it should be slightly withdrawn and the direction adjusted.
• The infiltration is given while withdrawing and reinserting the needle several times. This fanwise infiltration is important in order to reach the whole of the subacromial bursa.
