ABSTRACT
An anatomic study of the coracoacromial ligament was conducted. The data collected from 20 anatomical preparations and the arthroscopic findings in 40 cases were compared. The shape and the tension of the ligament were evaluated, as well as the thickness. Anatomic tradition describes the ligament as a fibrous triangular lamina inserted with its apex on the acromial tip and its base on the lateral edge of the coracoid. It simply closes the coracoacromial arch and has no mechanical role. However, our observations suggest that the ligament has a trapezoidal shape and is situated below the acromion with a wide reflex portion. Its thickness varies from 2 to 5.6 mm. Given that structure, the ligament appears like a robust suspension structure of the coracoid, which contrasts the action of the muscles that connect to it. From these observations, a pathogenic hypothesis of the subacromial impingement proposes itself.

The results of experimental research into the physical, physiological and biological effects on the tissues of electromagnetic fields are analysed. The research was conducted on 354 patients either hospitalised or treated in outpatients departments for orthopaedic conditions. These patients were treated with electromagnetic currents for a period of 10 days and the effects mainly on oedema, pain and inflammation were evaluated. The effects were distinctly positive especially in the case of acute lesions. In addition, no unpleasant or harmful topical or systemic side effects were observed.
