Having relatively recently, undergone subacromial decompression surgery I thought that I should write about my experience to help ease any worries of other people who are anticipating a similar operation.

A shoulder impingement can come about for a variety of reasons and the treatment will vary depending on the cause of the injury.

Within the shoulder there is a narrow passage, known as the subacromial space, that runs between the head of the upper arm bone or humerus and a part of the shoulder blade known as the acromion.

Through this channel run the tendons of the supraspinatus muscle. The Supraspinatus is one of the four muscles that make up the rotator cuff which pull the arm into the shoulder joint, to stabilize the joint and help with rotational movement of the arm.
