Coracoid impingement is an uncommon problem and rarely occurs alone without some other change in the nearby anatomic structures contributing to the problem. Idiopathic, traumatic, and iatrogenic etiologies have been identified. Subcoracoid impingement, which is defined as narrowing of the space between the coracoid process and the humerus, is an uncommon and infrequently recognized cause of shoulder pain. For example, rotator cuff tears or degeneration or an unusual shape or length of the coracoid bone can lead to coracoid impingement. Subcoracoid impingement, also known as coracoid impingement, is defined as encroachment of the coracoid process on the lesser tuberosity of the humerus. In all three the clinical findings consisted of pain in front of the shoulder, referred to the upper arm and forearm, a … Subcoracoid impingement may cause undersurface Subscapularis tears via the “Roller-Wringer Effect”. This leads to impingement of the subscapularis tendon as it courses through the coracohumeral space (7,27,28). Proper diagnosis requires a focused clinical examination of the anterior shoulder and adjacent structures. Subcoracoid Impingement: Impingement of the coracoid process against the humerus (usually the lesser tuberosity) in a coracoid impingement position (humerus is flexed, adducted and internally rotated). Coracoid impingement is an uncommon problem and rarely occurs alone without some other change in the nearby anatomic structures contributing to the problem. The coracoid process works together with the acromion to stabilize the shoulder joint The acromion is a curved piece of bone that comes from the back of the shoulder blade around and over the top of the shoulder joint. The subacromial space lies underneath the acromion, the coracoid process, the acromioclavicular joint and the coracoacromial ligament. The known etiologies of subcoracoid impingement are anatomic variations of the scapulae (coracoid process), ossifications of the subscapularis tendon ( Fig. Subcoracoid impingement is an unusual form of shoulder impingement, and results from narrowing of the coracohumeral interval (space between the tip of the coracoid and the humerus).Narrowing is typically seen in the setting of prior rotator cuff repair, but occasionally also results from congenital narrowing or trauma. It is an important entity to be aware of because it has been identified as a cause of persistent postoperative shoulder pain after rotator cuff repair [ 1 ]. Symptomatic impingement of the rotator cuff between the humeral head and the coracoid process has been studied and three varieties recognised: idiopathic, iatrogenic and traumatic. For example, rotator cuff tears or degeneration or an unusual shape or length of the coracoid bone can lead to coracoid impingement. Coracoid impingement is a controversial, well-known diagnosis that results in anterior shoulder pain. A: The coracoid process is a small hook-like structure at the top front part of the scapula (shoulder blade). Impingement of the tendinous rotator cuff on the coracoid process (subcoracoid impingement syndrome) has rarely been reported as a cause of pain after surgery for rotator cuff tear. The coracoid impingement test works like this: The PT stands beside you and raises your arm to shoulder level with your elbow bent at a 90 … Keywords Coracoid impingement Subcoracoid impingement Coracohumeral distance Coracohumeral interval Introduction In 1909, Goldthwait [20] was the first to describe a possible rotator cuff impingement by the coracoid process.
