Subacromial injection is used to treat a variety of painful conditions, including adhesive capsulitis, rotator cuff tendinosis, and impingement syndrome. The physician may choose an injection site on the front, side or rear of the shoulder. During a subacromial injection, a mixture of anesthesia and anti-inflammatory medication is injected into the space between the acromion and the head of the humerus.
The patient is placed in a seated position, and the skin on the shoulder is cleaned and anesthetized.
The physician carefully inserts a needle into the joint space and injects the medicated solution. The mixture bathes the joint space to reduce pain and inflammation in the joint.
End of Procedure and Aftercare
The needle is removed, and a small bandage is placed on the shoulder. The patient may be advised to avoid strenuous activity for the next few days.
