“…MRI has also been used in the assessment of CHD. Specifically, one study has reported values of 0.72 cms [5] in maximal shoulder internal rotation, while with shoulder neutral rotation, values of 1.12 (0.33) cms have been found [10], which are in consonance with the results from this paper. Our values were similar in CHD at 0 degrees of shoulder evaluation (1.03 ± 0.21 cms) to those obtained by Oh et al [13] (1.01 ± 0.21 cms), but in different patient samples (anterior shoulder pain versus full rotator cuff tear).…”

“…Although it can occur alone, it usually presents with anterolateral shoulder pain (labeled as subacromial pain syndrome), sharing similar symptoms [5] and making it difficult to diagnose. The most related cause of anterior shoulder pain is subcoracoid impingement syndrome, defined as the encroachment of the posterolateral coracoid process upon the lesser tuberosity of the humerus [6], causing a compression of soft tissues, such as the subscapularis tendon, glenohumeral joint capsule and subcoracoid bursa, and occasionally the long head of the biceps tendon [7].…”

“…The coracohumeral interval (CHI) has been measured in previous investigations using the coracohumeral distance (CHD) to determine the severity of anterior shoulder pain [5, 6, 10], sometimes by means of computed tomography or magnetic resonance imaging (MRI). However, there is a clear lack of standard procedure to quantify it.…”

BackgroundThe aim of this study was twofold: (i) to assess the intrarater reliability of coracohumeral distance; (ii) to investigate the level of association between coracohumeral distance measured by ultrasonography, and pain-disability and shoulder range of movement, in patients suffering from chronic anterior shoulder pain.MethodsAn observational, cross sectional study was carried out. A convenience sample comprised of 87 patients with chronic anterior shoulder pain was assessed from 3 primary care centres. Main outcomes as pain and function were measured through the shoulder pain and disability index. Furthermore, shoulder range of movement-free of pain in shoulder elevation, as well as coracohumeral distance at both 0 and 60 degrees, were collected.ResultsAbsence of any correlation was found between coracohumeral distance and shoulder pain and disability index at both 0 and 60 degrees of shoulder elevation. Furthermore, absence of any correlation was found between coracohumeral distance measurements and active shoulder range of movement -free of pain.ConclusionsThere was poor association between coracohumeral distance and shoulder pain and function, as well as with shoulder range of movement, in patients with chronic anterior shoulder pain. Hence, clinicians should consider, not only increasing this space, but also other possibilities in their therapies, when patients with anterior shoulder pain are treated.Trial registration ACTRN12614000144617.

“…Despite our incomplete understanding of this clinical entity, several authors have published favorable outcomes relating to the treatment of subcoracoid impingement. 7 , 16 , 19 , 25 Lo et al 16 evaluated a small cohort of patients with combined subacromial impingement and subcoracoid impingement. In that series, all patients underwent subacromial decompression, subcoracoid decompression, and rotator cuff repair.…”

“… 25 These authors noted that subcoracoid impingement may be a cause of persistent symptoms after rotator cuff repair. 25 Interestingly, Misirlioglu et al 19 showed that arthroscopic subacromial decompression in patients with both subacromial and subcoracoid impingement resulted in improvement of the coracohumeral distance and resolution of both subacromial and subcoracoid impingement symptoms. Garofalo et al 7 performed several different surgical procedures in patients with subcoracoid impingement syndrome (4 men/9 women).…”

Background:Subcoracoid impingement has been implicated as a cause of anterior shoulder pain and subscapularis tendon tears.Purpose/Hypothesis:The purpose of this study was to evaluate the bony anatomy of the coracoid process and the subcoracoid space. We hypothesized that age-related changes that may contribute to subcoracoid impingement occur in the subcoracoid space.Study Design:Descriptive laboratory study.Methods:In total, 418 skeletal shoulder specimens were included in this study. We utilized 214 shoulders from a young cohort (25-35 years of age) and 204 shoulders from an older cohort (>55 years of age) for comparison. We evaluated several morphological characteristics of the coracoid process and the subcoracoid space: coracoid width, coracoid shape, coracoid thickness, and subcoracoid distance. Each coracoid was observed for the presence of spurring or other morphological changes.Results:The mean anteroposterior (AP) thickness of the coracoid tip was 7.9 and 9.4 mm in our young female and male cohorts, respectively, while the mean AP thickness was 8.1 and 9.7 mm in our older female and male cohorts, respectively. The coracoid tip was hooked in 31 of 108 young female shoulders compared with 55 of 102 older female shoulders, and the coracoid tip was hooked in 25 of 106 young male shoulders compared with 45 of 102 older male shoulders. The mean subcoracoid distance in neutral rotation was 14.8 and 12.5 mm in young and older female shoulders, respectively, while the mean subcoracoid distance in internal rotation in these same cohorts was 8.7 and 7.0 mm, respectively. The mean subcoracoid distance in neutral rotation was 14.8 and 13.3 mm in young and older male shoulders, respectively, while the mean subcoracoid distance in internal rotation was 8.6 and 8.1 mm in young and older male shoulders, respectively.Conclusion:The principal findings of our study demonstrate that anatomic changes implicated in subcoracoid impingement may be developmental and worsen with age. The subcoracoid space was narrower in our older cohort of shoulders. Additionally, these older shoulders also had a greater AP width and a more hooked coracoid compared with young shoulders.Clinical Relevance:Narrowing of the subcoracoid space has been shown to be implicated as a cause of anterior shoulder pain and subscapularis tendon tears. This is the first study to show that the morphological changes implicated in subcoracoid impingement become more prevalent with age. This may help to explain the increasing prevalence of subscapularis tendon tears in older patients. Furthermore, subcoracoid decompression may be seen as an option for older patients with anterior shoulder pain and subscapularis tendon tears.

Prevalence of the Association of Subacromial Impingement with Subcoracoid Impingement and Their Clinical Effects

Abstract: Chronic subacromial impingement occurred together with subcoracoid impingement in 35% of patients presenting with chronic shoulder pain. Following ASD, the coracohumeral distance increased with remission from pain.
