Abstract

Subacromial impingement syndrome is one of the most frequent causes of shoulder pain. Patients are commonly referred to the shoulder specialist for severe pain and limited function of the shoulder joint. The shoulder is a complex joint that needs to be balanced to work properly. Mechanical forces have to be counteracted by muscle action and capsular ligament structures. When the balance is lost, the humeral head is not properly controlled during shoulder movements. This can lead to abnormal humeral head motion within the glenohumeral joint and conflict with the surrounding bony structures.

Conservative treatment solves the majority of subacromial impingement syndromes; however, cases resistant to this treatment need a surgical approach. Arthroscopic decompression is a quick and safe procedure that gives good results with a low rate of complication and failures. A correct diagnosis and indication are a prerequisite to achieve relief of symptoms and a good clinical result.
