Posterosuperior impingement also known as internal impingement is a relatively uncommon form of shoulder impingement primarily involving the infraspinatus tendon and the posterosuperior glenoid labrum.

. PSI is described as posterior glenohumeral translation that reproduces symptoms outside the normal physiologic translation in an individual and only accounts for about 5 of all patients with shoulder instabilities. Overhead work or play tennis pitching Pain rolling on shoulder in bed night pain. Empty Can Provocative Screen.

The first symptom is pain at the front side of your shoulder. And thus increasing posterior shoulder mobility is part of the treatment protocol for many with shoulder pain. Internal impingement is characterized by posterior shoulder pain when the athlete places the humerus in extreme external rotation and abduction as in the cocking phase of pitching or throwing.

Defining posterior shoulder instability PSI is therefore difficult not only defining it within this continuum but differentiating it from other shoulder pathologies. Internal impingement is a condition that occurs in athletes in which the shoulder is put in extreme abduction and external rotation during overhead movements. The best way to treat this is to have the patient practice throwing the ball for about a couple of weeks along with taking care to strengthen his or her calf muscles.

The shoulder impingement syndrome symptoms are different for each of the various causes. This pain has a very nagging character. Internal posterosuperior impingement syndrome is typified by a painful shoulder due to impingement of the soft tissue including the RC joint capsule and the posterosuperior part of the glenoid.

In the first stage of posterior superior glenoid impingement there is a certain stiffness that is felt by the patient around the affected shoulder. Posterior shoulder pain produced by contact of the greater tuberosity with the posterosuperior aspect of the glenoid when the shoulder is abducted to approximately 90 degrees and fully externally rotated produces impingement of the posterior rotator cuff capsule and labrum Gold 2007 Walch 1992.

The aetiology of this syndrome is unclear but hypotheses include anterior shoulder instability or micro-instability contracture of the posterior capsule reduced humeral retroversion and scapular dyskinesis.

A tight posterior cuff is associated with a handful of shoulder dysfunctions like subacromial impingement syndrome posterior impingement anterior instability etc. Internal impingement is caused by repetitive impingement of the posterior supraspinatus tendon infraspinatus tendon rotator cuff muscles between the humeral head long bone of the arm and the glenoid of the scapula the cupped portion of the shoulder blade.

If younger and really looks like impingement think instability. Treatment for a posterior impingement includes stretching the muscles of your chest and neck and strengthening the muscles of the shoulder blade to bring the shoulder down and back.
