Os acromiale is a developmental aberration in which the distal acromion fails to fuse. Objectives: The literature indicates that reduced acromiohumeral distance (AHD) and increased critical shoulder angle (CSA) are associated with large and massive rotator cuff (RC) tears which may not be amenable to a successful repair.The purpose of this study was to examine the overall accuracy of these two radiographic features in diagnosing significant RC pathology.

Patients with an AHI 7 mm suggests a large rotator cuff tear 4, 6 and < 6 mm suggests a longstanding, total infraspinatus tear 7. Consequently, the humeral head migrates proximally and decreases the acromiohumeral interval, predisposing the cuff to further injury and degeneration. If the spur extends inferior, it can be called a subacromial spur. Figure 12-5. The ball is much larger than the socket, and some say that a good analogy is that the humeral head on the socket is like a beach ball on a dinner plate. Effect of anterior supraspinatus tendon partial-thickness tears on infraspinatus tendon strain through a range of joint rotation angles. We sought to determine how various types of full-thickness rotator cuff tears, fatty degeneration of the rotator cuff muscles, duration of symptoms, and mechanism of injury affect the sizes of the acromiohumeral and coracohumeral intervals. summary.

This is the American ICD-10-CM version of M25.9 - other international versions of ICD-10 M25.9 may differ. This prospective study assessed interobserver and intraobserver variability in the radiographic measurement of the acromiohumeral interval. The acromiohumeral interval was measured as the smallest distance from the inferior surface of the acromion to the superior aspect of the humerus ( Fig 1 ). Fehringer EV, Rosipal CE, Rhodes DA, Lauder AJ, Puumala SE, Feschuk CA, Mormino MA, Hartigan DE. The glenohumeral joint is the one most people think of as the shoulder joint. This aberration is often discovered incidentally but may present with a clinical picture similar to that of subacromial impingement syndrome. ACUTE One study showed a relative measure (dividing the distance from the center of the humeral head to the undersurface of the acromion by the radius of the humeral head18) proved much more accurate and reliable in measuring the subacromial space, compared with the absolute measure of the acromion-humeral interval. The acromiohumeral interval was measured in millimeters. Fig 7 Acromial slope (AS) measurement in standard outlet view. The radiographic acromiohumeral interval is affected by arm and radiographic beam position . Normal radiographic measurements of the shoulder. 1).

PMC ACROMION Part of the scapula (large triangular bone in the upper back on each side) that meets the collar bone. may show a decreased acromiohumeral interval <7 mm on true AP shoulder radiograph in chronic tears <2 mm on an 'active abduction' view in acute tears. The aim of this study was twofold: (i) to investigate the intrarater reliability of acromiohumeral distance measurement; (ii) to assess the level of association between acromiohumeral distance measured by ultrasonography, and the degree of supraspinatus tendon tear, in patients suffering from chronic shoulder pain.
