Abstract
Aim of the work
To discuss the impingement syndrome as regarding anatomical features, biomechanical evaluation, pathological changes, etiological factors, diagnosis, both clinically and investigatory and different methods of treatment.
Summary
A majority of patients have restricted shoulder motion associated with pain and muscle spasm of the shoulder as the arm is forward flexed. A positive impingement sign and impingement test proved to be more or less reliable in establishing a diagnosis of impingement syndrome. Plain radiology, bursography, arthrography, ultrasonography, computerized tomography, magnetic resonance imaging and arthroscopy of the shoulder, each of them play its role in diagnosing impingement syndrome.
As regards treatment if impingement syndrome, it is eighther non surgical or surgical. Non surgical treatment improves most of cases and composed of rest, no steroidal anti inflammatory medications, corticosteroid injection, physiotherapy and exercises. When this treatment fails in improving the condition of the patient, then surgical treatment must be done. Among different decompression procedures that have been reported, is the anterior acromioplasty described by Neer, (1992) and modified by Rockwood, (1993). It seems to be the most effective one, and it can be combined with rotator cuff repair or resection of the lateral end of the clavicle when indicated. The efficacy of open acromioplasty has been well documented. With the advancement of shoulder arthroscopy, techniques have been developed for arthroscopic acromioplasty.
