The soft tissue attachments to the coracoid (lateral coracoacromial ligament
stump and medial pectoralis minor tendon) need to be adequately elevated off the coracoid to visualize the bony margins and appropriately center the drill guide.
Impingement syndrome of the shoulder is defined as the encroachment of the acromion, coracoacromial ligament
, coracoid process and/or acromioclavicular joint on the rotator cuff mechanism that passes beneath them when the glenohumeral joint is moved, particularly during flexion and rotation.
thickening is associated with impingement of supraspinatus tendon leading to supraspinatus pathologies and coracohumeral ligament thickening is associated with impingement of subscapularis pathology.
The static constraints are the acromioclavicular ligaments, the coracoclavicular ligaments, and the coracoacromial ligament
. The acromioclavicular ligaments surround the AC joint and are comprised of the superior, inferior, anterior, and posterior ligaments.
Intraoperatively, they noted that the coracoacromial ligament
, conjoint tendon, and pectoralis minor remained attached to the coracoid fracture fragment.
Patients with subacromial impingement were managed by a subacromial decompression, with partial resection of the coracoacromial ligament
. Before the end of the procedure, the integrity of the articular side of the tendon was checked.
