Posterior Approach for Intra-Articular Steroid Injection for Shoulder Arthropathy and Subacromial Impingement Syndrome: Simple Techniques
Anterior approach for intra-articular injections for shoulder joint is used traditionally. It has the disadvantage that anteriorly the space is narrow and one may find difficulty while introducing needle into the joint. Anteriorly, it is very difficult to approach the sub-acromial space. Posterior approach has the advantage that it is wide posteriorly and one can inject not only into subacromial area just below the angle of acromion but also into the shoulder joint 2 - 3 cm further below the acromion angle.
