Prospective randomized comparison of ultrasound-guided and neurostimulation techniques for continuous interscalene brachial plexus block in patients undergoing coracoacromial
The procedure provides both static and dynamic stabilizing forces from the bone and tendon sling respectively, and repair augmentation is possible by incorporating the capsulolabral tissues together with the remnant of the coracoacromial
The cause of subacromial syndrome is compression of the soft tissues (rotator cuff muscles and subacromial bursae) in the subacromial space by the head of the humerus, acromion, coracoacromial
ligament and coracoid process (Ertem et al., 1990; Romanes; Aktan et al.; Unal et al., 1997; Ebraheim et al.; Taskinalp et al.; von Schroeder et al.).
The MRI revealed a type II AC injury (according to the Rockwood classification)  with oedema of the coracoclavicular ligament and an intact coracoacromial
ligament was released with the deltoid and reattached at the conclusion of the operation.
The tests were originally established to detect the pathology of a primary compressive shoulder impingement, as a direct result of compression of the rotator cuff tendons between the humeral head and the overlying anterior third of the acromion, the coracoacromial
ligament, and the coracoid, with a positive test indicated by pain [3,4].
In 1972 Weaver and Dunn first described the treatment of AC dislocations through excision of the lateral border of the clavicle and transfer of the coracoacromial
ligament to the clavicle .
Coracoid process is a small hooked structure located on the scapular neck that arises anteriorly and serves as attachment for the coracoacromial
, coracoclavicular and coracohumeral ligament, as well as for tendons of the coracobrachial, small pectoral and short head of the biceps brachii muscle.
ligament surface was fibrillated or rough in all of the patients, indicating the presence of subacromial impingement.
After that, the pectoralis minor tendon and coracoacromial
ligament were detached and the bone was used as a bony block in the anterior inferior glenoid region between superior one-third two-third of the subscapularis muscle (8).
