About

Subacromial shoulder injections can be approached from the front or side of the shoulder. The investigators are comparing both methods, to find which one has better spread in the subacromial space.

Full description

Both lateral and posterio-lateral methods of subacromial injections are widely used for diagnostic and therapeutic purposes. It is not known which method allows the most accurate access into the subacromial space and is more effective.

The investigators have been using a novel approach from the anterior aspect of the shoulder for years with good clinical effect and propose comparing this approach to the described approach. This study will indicate which method is best and will be of practical clinical importance. The investigators feel the technique is easier to perform than other described methods and could be taught to clinicians throughout the country and adopted as the standard approach.
