Periprocedural Care

Equipment

Acromioclavicular (AC) joint injection is performed with the following equipment:

  • Needle, 25 gauge, 1-1.5 in.
  • Syringe, 3-5 mL
  • Povidone-iodine swabs or solution
  • Gauze pads, 4 × 4 in.

No consensus exists on the type or amount of steroids to be used for an AC joint injection. Typically, 0.25-0.5 mL of one of the following steroids is injected [5] :

  • Betamethasone sodium phosphate
  • Betamethasone acetate
  • Methylprednisolone, 40 mg/mL

Patient Preparation

Anesthesia

Typical anesthetics used include 0.5-1 mL of 1-2% lidocaine or 0.25-0.5% bupivacaine. A 2007 survey of western US physicians by Skedros et al found broad variations in the amount of anesthetic injected for painful shoulder conditions, with surgeons using larger volumes. [6]

Positioning

The patient can sit or stand, with the affected arm in a neutral position at the side.
