Answer

Injection of the subacromial space for the treatment of rotator cuff tendinitis and shoulder impingement syndrome is a common and useful procedure. [33, 34] This can also be used diagnostically to differentiate between local and referred pain. The posterolateral approach, as follows, is safe and easy to execute [11] :

  • Palpate the posterior tip of the acromion, and insert the needle into the space between the acromion and the head of the humerus.

  • Angle the needle anteriorly toward the coracoid process.

  • Once in the space, draw back on the syringe to ensure that the needle is not in a vascular structure. Resistance during delivery of the medication should be minimal.
