It resides in the subacromial space, the gap between the curved underside of the acromion and the head of the humerus. Corticosteroid injections may be used for acute flare-ups to provide rapid anti-inflammatory relief.
Understanding the Benefits of Subacromial Bursa Injection Corticosteroid
This space is critical because it houses not only the bursa but also the tendons of the rotator cuff, notably the supraspinatus. The subacromial bursa is a small, fluid-filled sac positioned between the acromion (the outer end of the shoulder blade) and the supraspinatus tendon, a key tendon of the rotator cuff.
The bursa itself is a synovial sac, meaning its lining produces synovial fluid, which reduces friction during the repetitive motions of the shoulder joint. Its primary function is to act as a lubricated cushion, allowing the tendon to glide smoothly beneath the bone during arm movements, particularly when lifting the arm overhead.
